Create an Image Share over LinkedIn API V2 not working

问题:

I use the api version 2.0 and want to create an image share.

Linkedin describes your image binary file upload prozess here: https://docs.microsoft.com/en-us/linkedin/consumer/integrations/self-serve/share-on-linkedin?context=linkedin/consumer/context#create-a-text-share

If you follow the instructions you will get a 400 HTTP error. I add the Content-Type in the header and get a 201 HTTP status with the X-RestLi-Id in the header. So far so good!

If I want to show my created post on linkedin (https://www.linkedin.com/in/me/detail/recent-activity/) I can't find the post with image.

How to fix it? Anybody got an idea?

PHP-Code:

           $imageRequestData = array(             "registerUploadRequest" => array(                 "recipes" => array(                     "urn:li:digitalmediaRecipe:feedshare-image"                 ),                 "owner" => $urn, // Person URN === urn:li:person:XXXX                 "serviceRelationships" => array(                     array(                         "relationshipType" => "OWNER",                         "identifier" => "urn:li:userGeneratedContent"                     )                 )             )         );         $image_request = $this->post('v2/assets?action=registerUpload', $imageRequestData);              $headers = array();             $headers[] = 'Authorization: Bearer ' . $this->accessToken;             $headers[] = 'X-Restli-Protocol-Version: 2.0.0';             $headers[] = 'Content-Type: ' . mime_content_type($image_path);  //ex. image/png             $ch = curl_init();             $options = array(                 CURLOPT_HEADER => true,                 CURLOPT_CUSTOMREQUEST => 'POST',                 CURLOPT_RETURNTRANSFER => true,                 CURLOPT_URL => $image_request['message']['value']['uploadMechanism']['com.linkedin.digitalmedia.uploading.MediaUploadHttpRequest']['uploadUrl'],                 CURLOPT_HTTPHEADER => $headers,                 CURLOPT_SSL_VERIFYPEER => false,                 CURLOPT_FOLLOWLOCATION => true,                 CURLOPT_POST => true,                 CURLOPT_CONNECTTIMEOUT => $this->connectTimeout,                 CURLOPT_TIMEOUT => $this->timeout,                 CURLOPT_POSTFIELDS => array("upload-file" => new CURLFile($image_path))             );             curl_setopt_array($ch, $options);             $response = curl_exec($ch);             $code = curl_getinfo($ch, CURLINFO_HTTP_CODE);             curl_close($ch);       $content = array(         'author' => $urn, // Person URN === urn:li:person:XXX         'lifecycleState' => 'PUBLISHED',         'specificContent' => array(             "com.linkedin.ugc.ShareContent" => array(                 'shareCommentary' => array(                     "text" => $comment,                 ),                 'shareMediaCategory' => 'IMAGE', //NONE - The share does not contain any media, and will only consist of text.  ||   ARTICLE - The share contains a URL.  ||  IMAGE - The Share contains an image.

You need to change your request to PUT and keep default for SSL VerifyPeer:

$headers = array(); $headers[] = 'Authorization: Bearer ' . $this->accessToken; $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', //need to set custom request to PUT instead of post     CURLOPT_RETURNTRANSFER => true,     CURLOPT_URL => $image_request['message']['value']['uploadMechanism']['com.linkedin.digitalmedia.uploading.MediaUploadHttpRequest']['uploadUrl'],     CURLOPT_HTTPHEADER => $headers,     // CURLOPT_SSL_VERIFYPEER => false, //keep default options     CURLOPT_FOLLOWLOCATION => true,     CURLOPT_POST => true,     CURLOPT_CONNECTTIMEOUT => $this->connectTimeout,     CURLOPT_TIMEOUT => $this->timeout,     CURLOPT_POSTFIELDS => array("upload-file" => new CURLFile($image_path)) ); curl_setopt_array($ch, $options); $response = curl_exec($ch); $code = curl_getinfo($ch, CURLINFO_HTTP_CODE); curl_close($ch); 

Or use GuzzleHttp\Client to simplify the upload:

$client =new \GuzzleHttp\Client(); $client->request('PUT', $image_request['message']['value']['uploadMechanism']['com.linkedin.digitalmedia.uploading.MediaUploadHttpRequest']['uploadUrl'], [         'headers' => [             'Authorization' => 'Bearer ' . $this->accessToken         ],         'body' => fopen($image_path, 'r'),      ]
