Usage

To post a message to a slack an easy way, create a hook object and send data with Angler.easy_throw!.

hook = SlackTsuribari::Hook.config('https://hooks.slack.com/services/webhook_url')
SlackTsuribari::Angler.easy_throw!(hook, 'test message')

Use Angler.throw! If you need a bit more control, like adding color.

hook = SlackTsuribari::Hook.config('https://hooks.slack.com/services/webhook_url')
payload = {
  attachments: [
    fallback: 'test message',
    text: 'test message',
    color: '#00FF00',
  ]
}
SlackTsuribari::Angler.throw!(hook, payload)

The second argument of throw! can specify the payload of slack's Incoming Webhook. See Setup Instructions of Incoming Webhook and Adding secondary attachment for arguments that can be specified in the payload.

proxy setting

If a proxy is needed, it can be configured as follows

hook = SlackTsuribari::Hook.config do |config|
  config.uri = 'https://hooks.slack.com/services/webhook_url'
  config.proxy_addr = '127.0.0.1'
  config.proxy_port = 8080
  config.proxy_user = 'test'
  config.proxy_pass = 'password'
  config.no_proxy = '192.168.1.1'
end
SlackTsuribari::Angler.easy_throw!(hook, 'test message')

pre payload setting

In config you can also set the channel, username, text and icon to post. The channel is set when you change the channel to post.

hook = SlackTsuribari::Hook.config do |config|
  config.uri = 'https://hooks.slack.com/services/webhook_url'
  config.pre_payload.channel = 'sample_channel'
end
SlackTsuribari::Angler.easy_throw!(hook, 'test message')

The username allows you to change the name of the post.

hook = SlackTsuribari::Hook.config do |config|
  config.uri = 'https://hooks.slack.com/services/webhook_url'
  config.pre_payload.username = 'Robot'
end
SlackTsuribari::Angler.easy_throw!(hook, 'test message')

The text allows you to set the text to be posted. If text is specified with easy_throw! or throw!, its setting is preferred.

hook = SlackTsuribari::Hook.config do |config|
  config.uri = 'https://hooks.slack.com/services/webhook_url'
  config.pre_payload.text = 'pre payload text'
end
SlackTsuribari::Angler.easy_throw!(hook) # => throw 'pre payload text'
SlackTsuribari::Angler.throw!(hook) # => throw 'pre payload text'

SlackTsuribari::Angler.easy_throw!(hook, 'text') # => throw 'text'
SlackTsuribari::Angler.throw!(hook, {text: 'text'}) # => throw 'text'

If you want to set an icon, put a value in either icon_url or icon_emoji. The icon_url is the URL of the icon. The icon_emoji is the text of the emoji to be set for the icon.

hook = SlackTsuribari::Hook.config do |config|
  config.uri = 'https://hooks.slack.com/services/webhook_url'
  config.pre_payload.icon_url = 'path to icon url'
end
SlackTsuribari::Angler.easy_throw!(hook, 'test message')

hook = SlackTsuribari::Hook.config do |config|
  config.uri = 'https://hooks.slack.com/services/webhook_url'
  config.pre_payload.icon_emoji = ':+1:'
end
SlackTsuribari::Angler.easy_throw!(hook, 'test message')
