Warning: Shared objects are not supported by the 4D NetKit API.

OAuth2Provider

The OAuth2Provider class allows you to request authentication tokens to third-party web services providers in order to use their APIs in your application. This is done in two steps:

Using the New OAuth2 provider component method, you instantiate an object of the OAuth2Provider class that holds authentication information.
You call the OAuth2ProviderObject.getToken() class function to retrieve a token from the web service provider.

Here's a diagram of the authorization process:

This class can be instantiated in two ways:

by calling the New OAuth2 provider method
by calling the cs.NetKit.OAuth2Provider.new() function

Warning: OAuth2 authentication in signedIn mode requires a browser. Since some servers have restrictions regarding the supported browsers (for example, check this Google support page), the functionality may not work properly.

New OAuth2 provider

New OAuth2 provider( paramObj : Object ) : cs.NetKit.OAuth2Provider

Parameters

Parameter	Type		Description
paramObj	Object	->	Determines the properties of the object to be returned
Result	cs.NetKit.OAuth2Provider	<-	Object of the OAuth2Provider class

Description

New OAuth2 provider instantiates an object of the OAuth2Provider class.

In paramObj, pass an object that contains authentication information.

The available properties of paramObj are:

Parameter	Type	Description	Optional
name	text	Name of the provider. Available values: "Microsoft", "Google" or "" (if "" or undefined/null attribute, the authenticateURI and the tokenURI need to be filled by the 4D developer).	Yes
permission	text	- "signedIn": Azure AD/Google will sign in the user and ensure they gave their consent for the permissions your app requests (opens a web browser). - service": the app calls Microsoft Graph with its own identity/Google (access without a user).	No
clientId	text	The client ID assigned to the app by the registration portal.	No
redirectURI	text	(Not used in service mode) The redirect_uri of your app, the location where the authorization server sends the user once the app has been successfully authorized. When you call the `.getToken()` class function, a web server included in 4D NetKit is started on the port specified in this parameter to intercept the provider's authorization response.	No in signedIn mode, Yes in service mode
scope	text or collection	Text: A space-separated list of the Microsoft Graph permissions that you want the user to consent to. Collection: Collection of Microsoft Graph permissions.	Yes
tenant	text	Microsoft: The {tenant} value in the path of the request can be used to control who can sign into the application. The allowed values are: - "common" for both Microsoft accounts and work or school accounts (default value) - "organizations" for work or school accounts only - "consumers" for Microsoft accounts only - tenant identifiers such as tenant ID or domain name. Google (service mode only): Email address to be considered as the email address of the user for which the application is requesting delegated access.	Yes
authenticateURI	text	Uri used to do the Authorization request. Default for Microsoft: "https://login.microsoftonline.com/{tenant}/oauth2/v2.0/authorize". Default for Google: "https://accounts.google.com/o/oauth2/auth".	Yes
tokenURI	text	Uri used to request an access token. Default for Microsoft: "https://login.microsoftonline.com/{tenant}/oauth2/v2.0/token". Default for Google: "https://accounts.google.com/o/oauth2/token".	Yes
tokenExpiration	text	Timestamp (ISO 8601 UTC) that indicates the expiration time of the token.	Yes
clientSecret	text	The application secret that you created for your app in the app registration portal. Required for web apps.	Yes
token	object	If this property exists, the `getToken()` function uses this token object to calculate which request must be sent. It is automatically updated with the token received by the `getToken()` function.	Yes
timeout	real	Waiting time in seconds (by default 120s).	Yes
prompt	text	(Optional) A space-delimited, case-sensitive list of prompts to present the user. Possible values are: - none: Do not display any authentication or consent screens. Must not be specified with other values. - consent: Prompt the user for consent. - select_account: Prompt the user to select an account. (if you don't specify this parameter, the user will be prompted only the first time your project requests access. )	Yes
loginHint	text	(Optional) This option can be used to inform the Google Authentication Server which user is attempting to authenticate if your application is aware of this information. By prefilling the email field in the sign-in form or by selecting the appropriate multi-login session, the server uses the hint to simplify the login flow either. Set the parameter value to a sub-identifier or email address that corresponds to the user's Google ID.	Yes
accessType	text	(Recommended) Indicates whether your application can refresh access tokens when the user is not present at the browser. Valid parameter values are online (default) and offline. Set the value to offline if your application needs to update access tokens when the user is not present at the browser. This is how access tokens are refreshed. This value instructs the Google authorization server to return a refresh token and an access token the first time that your application exchanges an authorization code for tokens.	Yes
clientEmail	text	(mandatory, Google / service mode only) email address of the service account used	No
authenticationPage	text or file object	Path of the web page to display in the web browser when the authentication code is received correctly in signed in mode (If not present the default page is used).	Yes
authenticationErrorPage	text or file object	Path of the web page to display in the web browser when the authentication server returns an error in signed in mode (If not present the default page is used).	Yes
PKCEEnabled	boolean	false by default. If true, PKCE is used for OAuth 2.0 authentication and token requests and is only usable for permission=”SignIn”.	Yes
PKCEMethod	text	"S256" by default. The only supported values for this parameter are "S256" or "plain".	Yes
thumbprint	text	Certificate thumbprint. Only usable with permission="Service"	Yes (No for certificate based authentication)
privateKey	text	Certificate private key. Only usable with permission="Service". (Google / service mode only) Private key given by Google. Mandatory if .permission="service" and .name="Google"	Yes (No for certificate based authentication)
clientAssertionType	text	The format of the assertion as defined by the authorization server. The value is an absolute URI. Default value: "urn:ietf:params:oauth:client-assertion-type:jwt-bearer". Only usable with permission="Service"	Yes
browserAutoOpen	boolean	True (default value), the web browser is open automatically. Pass false if you don't want the web browser to open automatically.	Yes

If you want the .getToken() function to use the Assertion Framework described in the RFC 7521 to connect to the server, make sure to pass the thumbprint and privateKey properties. If clientSecret, thumbprint and privateKey are present, the thumbprint is used by default and the RFC 7521 is used to connect. For more information, please refer to the OAuth2.0 authentication using a certificate blog post.

Note: The authenticationPage and authenticationErrorPage and all the resources associated must be in the same folder.

Returned object

The OAuth2 provider returned object cs.NetKit.OAuth2Provider properties correspond to those of the paramObj object passed as a parameter and some additional properties:

Property	Type	Description
paramObj.properties		< properties passed in parameter `paramObj`>
authenticateURI	text	Returns the calculated authenticateURI. Can be used in a webbrowser or in a web area to open the connection page.
isTokenValid	Function	`OAuth2Provider.isTokenValid() : boolean` Verifies the token validity. - If no token is present, returns false. - If the current token is not expired, returns true. - If the token is expired and no refresh token is present, returns false. - If a refresh token is present, automatically requests a new token and returns true if the token is generated correctly, otherwise false.

Example 1

//authentication into google account and token retrieval

var $File1; $File2 : 4D.File
var $oAuth2 : cs.NetKit.OAuth2Provider
var $param: Object

$File1:=File("/RESOURCES/OK.html")

var $oauth2:=cs.NetKit.OAuth2Provider.new($credential)
var $token:=Try($oauth2.getToken())
if ($token=null)
  ALERT("Error: "+Last errors[0].message)
end if

Example 3

// Initial authentication with Microsoft OAuth2 and retrieval of token with refresh token

// Define OAuth2 provider details for Microsoft
$provider:=New object()
$provider.name:="Microsoft"
$provider.permission:="signedIn"
$provider.clientId:="xxx-xxx-xxx-xxx-c460fc"
$provider.redirectURI:="http://127.0.0.1:50993/authorize/"
$provider.scope:="https://graph.microsoft.com/.default"

// Use the "offline" parameter to request a refresh token in addition to the regular access token
$provider.accessType:="offline"

// Create new OAuth2 object for Microsoft
$OAuth:= cs.NetKit.OAuth2Provider.new ($provider)

// Request the token, which includes the refresh token
var $myCurrentToken : Object := $OAuth.getToken()

// After receiving the token and refresh token, save it for future token requests

#DECLARE($myCurrentToken : object)
var $provider:=New object()
$provider.name:="Microsoft"
$provider.permission:="signedIn"
$provider.clientId:="xxx-xxx-xxx-xxx-c460fc"
$provider.redirectURI:="http://127.0.0.1:50993/authorize/"
$provider.scope:="https://graph.microsoft.com/.default"

// Include the token from the previous request
$provider.token:=$myCurrentToken

// Re-create OAuth2 object with the stored token
$OAuth:= cs.NetKit.OAuth2Provider.new ($provider)

// getToken() checks if the token has expired
// If the token is still valid, it returns the current token
// If the token has expired, it automatically requests a new one
// If a refresh token is present, the token is automatically renewed without user sign-in
// If no refresh token is available, the user will need to sign in again
$myCurrentToken:=$OAuth.getToken()

Note: Some servers, like Google, do not always return the refresh token during subsequent token requests. In such cases, you should remember to include the refresh token in the token object before saving it for future use.

OAuth2ProviderObject.getToken()

OAuth2ProviderObject.getToken() : Object

Parameter	Type		Description
Result	Object	<-	Object that holds information on the token retrieved

Description

.getToken() returns an object that contains a token property (as defined by the IETF), as well as optional additional information returned by the server:

Property	Object properties	Type	Description
token		Object	Token returned
	expires_in	Text	How long the access token is valid (in seconds).
	access_token	Ttext	The requested access token.
	refresh_token	Text	Your app can use this token to acquire additional access tokens after the current access token expires. Refresh tokens are long-lived, and can be used to retain access to resources for extended periods of time. Available only if the value of the `permission` property is "signedIn".
	token_type	Text	Indicates the token type value. The only token type that Azure AD supports is "Bearer".
	scope	Text	A space separated list of the Microsoft Graph permissions that the access_token is valid for.
tokenExpiration		Text	Timestamp (ISO 8601 UTC) that indicates the expiration time of the token

If the value of token is empty, the command sends a request for a new token.

If the token has expired:

If the token object has the refresh_token property, the command sends a new request to refresh the token and returns it.
If the token object does not have the refresh_token property, the command automatically sends a request for a new token.

When requesting access on behalf of a user ("signedIn" mode) the command opens a web browser to request authorization.

In "signedIn" mode, when .getToken() is called, a web server included in 4D NetKit starts automatically on the port specified in the redirectURI parameter to intercept the provider's authorization response and display it in the browser.

Office365

The Office365 class allows you to call the Microsoft Graph API to:

Example: Create an email with a file attachment and send it

Send an email with an attachment, on behalf of a Microsoft 365 user:

var $oAuth2 : cs.NetKit.OAuth2Provider
var $token; $param; $email; $status : Object

// Set up authentication
$param:=New object()
$param.name:="Microsoft"
$param.permission:="signedIn"
$param.clientId:="your-client-id" // Replace with your client ID
$param.redirectURI:="http://127.0.0.1:50993/authorize/"
// Ask permission to send emails on behalf of the Microsoft user
$param.scope:="https://graph.microsoft.com/Mail.Send"  

$oAuth2:=New OAuth2 provider($param)

$token:=$oAuth2.getToken()

// Create the email, specify the sender and the recipient
$email:=New object()
$email.from:=New object("emailAddress"; New object("address"; "[email protected]")) // Replace with sender's email
$email.toRecipients:=New collection(New object("emailAddress"; New object("address"; "[email protected]")))
$email.body:=New object()
$email.body.content:="Hello, World!"
$email.body.contentType:="html"
$email.subject:="Hello, World!"

// Create a text file and attach it to the email
var $attachment : Object
var $attachmentText : Text

$attachmentText:="Simple text file"
BASE64 ENCODE($attachmentText)
$attachment:=New object
$attachment["@odata.type"]:="#microsoft.graph.fileAttachment"
$attachment.name:="attachment.txt"
$attachment.contentBytes:=$attachmentText
$email.attachments:=New collection($attachment)

// Send the email
$Office365:=New Office365 provider($token; New object("mailType"; "Microsoft"))
$status:=$Office365.mail.send($email)

Status object

Several Office365.mail functions return a standard **status object**, containing the following properties:

Property	Type	Description
success	Boolean	True if the operation was successful
statusText	Text	Status message returned by the server or last error returned by the 4D error stack
errors	Collection	Collection of errors. Not returned if the server returns a `statusText`
id	Text	- `copy()` and `move()`: returned id of the mail. - `createFolder()` and `renameFolder()`: returned id of the folder

Basically, you can test the success and statusText properties of this object to know if the function was correctly executed.

Error handling

When an error occurs during the execution of an Office365.mail function:

if the function returns a **status object**, the error is handled by the status object and no error is thrown,
if the function does not return a status object, an error is thrown that you can intercept with a project method installed with ON ERR CALL.

Office365.user.get()

Office365.user.get( id : Text { ; select : Text }) : Object
Office365.user.get( userPrincipalName : Text { ; select : Text }) : Object

Parameters

Parameter	Type		Description
id	Text	->	Unique identifier of the user to search for
userPrincipalName	Text	->	User principal name (UPN) of the user to search for
select	Text	->	Set of properties to be returned
Result	Object	<-	Object holding information on the user

Description

Office365.user.get() returns information on the user whose ID matches the id parameter, or whose User Principal Name (UPN) matches the userPrincipalName parameter.

The UPN is an Internet-style login name for the user based on the Internet standard RFC 822. By convention, it should correspond to the user's email name.

If the ID or UPN is not found or connection fails, the command returns an object with Null as a value and throws an error.

In select, you can pass a string that contains a specific set of properties you want to retrieve. Each property must be separated by a comma (,). If the select parameter is omitted, the function returns an object with a predefined set of properties (see below).

The list of available properties is available on Microsoft's documentation website.

Returned object

By default, if the select parameter is omitted, the command returns an object with the following properties:

Property	Type	Description
id	Text	Unique identifier for the user
businessPhones	Collection	The user's phone numbers.
displayName	Text	Name displayed in the address book for the user.
givenName	Text	The user's first name.

For more details on user information, see Microsoft's documentation website.

Office365.user.getCurrent()

Office365.user.getCurrent({select : Text}) : Object

Description

Office365.user.getCurrent() returns information on the current user. In this case, it requires a signed-in user, and therefore a delegated permission.

The command returns a Null object if the session is not a sign-in session.

In select, pass a string that contains a set of properties you want to retrieve. Each property must be separated by a comma (,).

By default, if the select parameter is not defined, the command returns an object with a default set of properties (see the property table).

Example

To retrieve information from the current user:

var $userInfo; $params : Object
var $oAuth2 : cs.NetKit.OAuth2Provider

filter	Text	Allows retrieving just a subset of users. See Microsoft's documentation on filter parameter.
select	Text	Set of properties to retrieve. Each property must be separated by a comma (,). By default, if `select` is not defined, the returned user objects have a default set of properties
top	Integer	Defines the page size for a request. Maximum value is 999. If `top` is not defined, the default value is applied (100). When a result set spans multiple pages, you can use the `.next()` function to ask for the next page. See Microsoft's documentation on paging for more information.
orderBy	Text	Defines how the returned items are ordered. By default, they are arranged in ascending order. The syntax is "fieldname asc" or "fieldname desc". Replace "fieldname" with the name of the field to be arranged.

Tutorials

Authenticate to the Microsoft Graph API in service mode

Objectives

Establish a connection to the Microsoft Graph API in service mode.

Prerequisites

You have registered an application with the Microsoft identity platform and obtained your application ID (also called client ID) and client secret.

Here, the term "application" does not refer to an application built in 4D. It refers to an entry point you create on the Azure portal. You use the generated client ID to tell your 4D application to trust the Microsoft identity platform.

Steps

Once you have your client ID and client secret, you're ready to establish a connection to your Azure application.

Open your 4D application, create a method and insert the following code:

var $oAuth2 : cs.NetKit.OAuth2Provider
var $office365 : cs.NetKit.Office365

var $credential:={}
$credential.name:="Microsoft"
$credential.permission:="service"

$credential.clientId:="your-client-id" //Replace with your Microsoft identity platform client ID
$credential.clientSecret:="your-client-secret" //Replace with your client secret
$credential.tenant:="your-tenant-id" // Replace with your tenant ID
$credential.scope:="https://graph.microsoft.com/.default"

$oAuth2:=New OAuth2 provider($credential)

$office365:=$cs.NetKit.Office365.new($oAuth2; {mailType: "MIME"})
// In service mode, you need to indicate on behalf of which user you are sending the request:
$office365.mail.userId:="MyUserPrincipalName"
// Get mails of MyUserPrincipalName account
$mailList:=$office365.mail.getMails()

Execute the method to establish the connection.

(Archived) Authenticate to the Microsoft Graph API in signedIn mode and send an email with SMTP

This tutorial has been archived. We recommend using the Office365.mail.send() method to send emails.

Objectives

Establish a connection to the Microsoft Graph API in signedIn mode, and send an email using the SMTP Transporter class.

In this example, we get access on behalf of a user.

Prerequisites

You have registered an application with the Microsoft identity platform and obtained your application ID (also called client ID).

Here, the term "application" does not refer to an application built in 4D. It refers to an entry point you create on the Azure portal. You use the generated client ID to tell your 4D application to trust the Microsoft identity platform.

You have a Microsoft e-mail account. For example, you signed up for an e-mail account with Microsoft's webmail services designated domains (@hotmail.com, @outlook.com, etc.).

Steps

Once you have your client ID, you're ready to establish a connection to your Azure application and send an email:

Open your 4D application, create a method and insert the following code:

var $token; $param; $email : Object
var $oAuth2 : cs.NetKit.OAuth2Provider
var $address : Text

// Configure authentication


$param:=New object
$param.name:="Microsoft"
$param.permission:="signedIn"
$param.clientId:="your-client-id" // Replace with your Microsoft identity platform client ID
$param.redirectURI:="http://127.0.0.1:50993/authorize/"
$param.scope:="https://outlook.office.com/SMTP.Send" // Get consent for sending an smtp email

// Instantiate an object of the OAuth2Provider class
$oAuth2:=New OAuth2 provider($param)

// Request a token using the class function

// Send a token request and start the a web server on the port specified in $param.redirectURI
//to intercept the authorization response
$token:=$oAuth2.getToken()

// Set the email address for SMTP configuration
$address:= "[email protected]" // Replace with your Microsoft email account address

// Set the email's content and metadata
$email:=New object
$email.subject:="My first mail"
$email.from:=$address
$email.to:="[email protected]" // Replace with the recipient's email address
$email.textBody:="Test mail \r\n This is just a test e-mail \r\n Please ignore it"

// Configure the SMTP connection
$parameters:=New object
$parameters.accessTokenOAuth2:=$token

$parameters.authenticationMode:=SMTP authentication OAUTH2
$parameters.host:="smtp.office365.com"
$parameters.user:=$address

// Send the email

$smtp:=SMTP New transporter($parameters)
$statusSend:=$smtp.send($email)

Execute the method. Your browser opens a page that allows you to authenticate.
Log in to your Microsoft Outlook account and check that you've received the email.
