Question

我使用的是api版本2.0，并且想要创建图像共享。

Linkedin在这里描述您的图像二进制文件上传过程： https://docs.microsoft.com/en-us/linkedin/consumer/integrations/self-serve/share-on-linkedin?context=linkedin/consumer/context#create-a-text-share

如果按照说明进行操作，则会收到400 HTTP错误。我在标头中添加Content-Type，并在标头中获得带有X-RestLi-Id的201 HTTP状态。到目前为止一切顺利！

如果我想在linkedin（https://www.linkedin.com/in/me/detail/recent-activity/）上显示我创建的帖子，则找不到带有图片的帖子。

如何解决？有人知道吗？

PHP代码：

           $imageRequestData = array(
            "registerUploadRequest" => array(
                "recipes" => array(

                ),
                "owner" => $urn, // Person URN === urn:li:person:XXXX

您需要将请求更改为PUT，并保持SSL VerifyPeer的默认设置：

$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);

或使用GuzzleHttp \ Client简化上传：

$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'),

    ]

通过LinkedIn API V2创建图像共享不起作用
