Found this error when use getTopMediasByTag() and getMediasByTag(). Caching user session

[javagose]

After several request (5 request or more) i get this error:

Catchable fatal error: Object of class stdClass could not be converted to string in
C:\xampp\htdocs\instagram\vendor\raiym\instagram-php-scraper\src\InstagramScraper\Instagram.php
on line 519

Getting the same error... dumping the $response var seems to be a security check from instagram... to verify that you are logging in to your account... Not sure the way around this

@javagose and @jonahfuller
thank you for comments

Could you please check how new version works for you?
I have added session caching. For caching purpose I use this library: https://github.com/PHPSocialNetwork/phpfastcache

You don't need to change your code.
But you can specify where to store cache (otherwise it will be stored somewhere in /vendor folder).
If you want specify session cache folder:

$instagram = Instagram::withCredentials('PASTE_LOGIN', 'PASTE_PASSWORD', '/path/to/folder/');
$instagram->login();

And you need call $instagram->login() only once after creating object. It will check for existing session for specified username.
If cache file exists it will call instagram.com to check if session is not expired. In all other cases (session file is not exists, session expired) it will login again.

This issue will be open until I implement following:

• In every function we need to check if session expired.
• If session expired library should try to login and continue
• If password is wrong it should throw corresponding exception

NOTE: Library does not track API limits, so you need adjust request frequency on your own

So far so good... I'll update if I find any issues. Thanks again for your continued work on this... Library is just what I needed to build my hashtaged photos wall.

Hello Raym and thank you for your job!
I had the same issue, I followed your instruction (updated your version to 0.5.3 with composer; added the path for the cache) but I get the same error.
This happens with php 7.1 and centOS 7 (if this could help you).
Thank you again!

@pinotarantino strange.
Can you please give more info about your situation.

What exactly you do? (How many requests you send, how frequently, what is delay time)

[pinotarantino]

Hello Raiym,
this issue happens immediatly, at the first request of top media by tags.
The issue happens with 'use phpFastCache\CacheManager' or without it.
Note that I've the problem of SSL certificate, issue #63 (if this could matter).

Here you are an extract of my code, if this could help you:

"...
require '/root/vendor/autoload.php';

use phpFastCache\CacheManager;

Unirest\Request::verifyPeer(false);

use InstagramScraper\Instagram ;

$instagram = Instagram::withCredentials('pxxxxxx', 'pxxxxxxx', '/var/www/html/socialtool');
$instagram->login();
...
$medias_top = Instagram::getTopMediasByTagName("$kw");
..."

Thanks a lot!
P;)

A clarification about SSL: I noticed now that with centOS, if I don't use 'Unirest\Request::verifyPeer(false)', it woks fine. I had the error of issue #63 in a previous project version developed on WAMP server. With Linux/Lamp the problem off SSL doesn't occur.

Thaks

Problem solved if I make the call from the same IP I used when I registered my account on Istagram...;)

i still get the same error

Object of class stdClass could not be converted to string in
C:\xampp\htdocs\instascrapper\vendor\raiym\instagram-php-scraper\src\InstagramScraper\Instagram.php on line
525

what i'm trying to build is a website that let users scrapp instagram content, so i build different php files, each file is calling a different Instagram.php Method.

for example, getTopMediasByTag.php call getTopMediasByTag(tags), getUserMedias.php calls getMedias(username), getUser.php call getAccount(username) ... etc

In each file i use

$instagram = Instagram::withCredentials('PASTE_LOGIN', 'PASTE_PASSWORD', '/path/to/folder/');
$instagram->login();

[peyvand]

require('autoload.php');

use InstagramScraper\Instagram;
Unirest\Request::verifyPeer(false);

$instagram = Instagram::withCredentials('username', 'password', '/cached');
$instagram->login();
