在Linkedin API上创建一个图像共享

Question

I'm not able to Create an Image Share, can you put some example code please or check my code.

I've already tried "Create a Text Share", "Create an Article or URL Share" on this link : https://docs.microsoft.com/en-us/linkedin/consumer/integrations/self-serve/share-on-linkedin (it work's)

I need to show if my code is good

I have create register_image() which work's well

Now I want to upload_image

public function upload_image($src_path, $image_request) {

    if(!file_exists($src_path)) return -1;

    $ch = curl_init();

    if ($ch === false) {
        throw new Exception('failed to initialize');
    }

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $image_request['value']['uploadMechanism']['com.linkedin.digitalmedia.uploading.MediaUploadHttpRequest']['uploadUrl'] . "&oauth2_access_token=" . $this->_access_token);

    $postData = array(
        'upload-file' => $src_path,
    );

    $str = http_build_query($postData);

    curl_setopt($ch, CURLOPT_POSTFIELDS, $str);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    $response = curl_exec($ch);

    if ($response === false) 
        $response = curl_error($ch);

    return $this->share_v3($image_request);


}

I get this error :
