I'm now working with Linkedin V2 integration with my application. I'm facing an issue while trying to upload image to Linkedin.
I have tried CURL request from my terminal(I'm using Ubuntu OS) & getting response as below:
Terminal command (Working & file uploaded):
curl -i --upload-file /Users/peter/Desktop/superneatimage.png --header "Authorization: Bearer redacted" 'https://api.linkedin.com/mediaUpload/C5522AQGTYER3k3ByHQ/feedshare-uploadedImage/0?ca=vector_feedshare&cn=uploads&m=AQJbrN86Zm265gAAAWemyz2pxPSgONtBiZdchrgG872QltnfYjnMdb2j3A&app=1953784&sync=0&v=beta&ut=2H-IhpbfXrRow1'
It's response as below:
HTTP/2 201 date: Wed Apr 10 09:14:44 UTC 2019 server: Play set-cookie: lang=v=2&lang=en-us; Path=/; Domain=api.linkedin.com x-ambry-creation-time: Wed Apr 10 09:14:44 UTC 2019 access-control-allow-origin: https://www.linkedin.com content-length: 0
I'm facing issue when I integrate the CURL request in my application. My CURL request code from my application is given below.
$headers = array();
$headers[] = 'Authorization: Bearer xxxxx';
$headers[] = 'X-Restli-Protocol-Version: 2.0.0';
$headers[] = 'Content-Type: multipart/form-data';
$ch = curl_init();
$options = array(
CURLOPT_HEADER => true,
CURLOPT_CUSTOMREQUEST => 'PUT',
CURLOPT_RETURNTRANSFER => true,
CURLOPT_URL => 'https://api.linkedin.com/mediaUpload/C5522AQGTYER3k3ByHQ/feedshare-uploadedImage/0?ca=vector_feedshare&cn=uploads&m=AQJbrN86Zm265gAAAWemyz2pxPSgONtBiZdchrgG872QltnfYjnMdb2j3A&app=1953784&sync=0&v=beta&ut=2H-IhpbfXrRow1',
CURLOPT_HTTPHEADER => $headers,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => array("upload-file" => '/Users/peter/Desktop/superneatimage.png')
// CURLOPT_POSTFIELDS => array("upload-file" => new CURLFile('/Users/peter/Desktop/superneatimage.png'))
);
curl_setopt_array($ch, $options);
$response = curl_exec($ch);
print_r($response);
$code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
Response as:
HTTP/1.1 400 Bad Request Server: Play Set-Cookie: lang=v=2&lang=en-us; Path=/; Domain=api.linkedin.com Date: Wed, 10 Apr 2019 09:16:25 GMT Content-Length: 0 X-Li-Fabric: prod-lsg1 Connection: keep-alive
Similar question from SO, which do not solved my issue.
Use Guzzle HTTP client instead of curl.I tried curl but it is not working.
First install the composer in the current directory with below command:
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === '48e3236262b34d30969dca3c37281b3b4bbe3221bda826ac6a9a62d6444cdb0dcd0615698a5cbe587c3f0fe57a54d8f5') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
After the composer Update, run below command to install the Guzzle (default version will be 3.9 it requires php >= 5.3.3.You can specify based on your php version):
php composer.phar require guzzlehttp/guzzle
Once Guzzle client installed successfully.Please use the below code to upload the file
require 'vendor/autoload.php';
$client =new \GuzzleHttp\Client();
$image_path='/path_to_your_image/my_image.png';
$result=$client->request('PUT',$target_url, [
'headers' => [
'Authorization' => 'Bearer ' . $token
],
'body' => fopen($image_path, 'r'),
]);
You will get below success full response

Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and trivial to integrate with web services.
