linkedin - 为什么在将照片上传到 LinkedIn API 时收到 CLIENT_ERROR？

问题描述

我正在使用 LinkedIn v2 api 制作图像共享。根据LinkedIn 文档，分为三个步骤。

  1. 注册要上传的图像。
  2. 将您的图片上传到 LinkedIn。
  3. 创建图像共享。

完成第 2 步后，我使用 /v2/assets/{asset-id} 检查上传状态并获得“CLIENT_ERROR”。我不知道这意味着什么，也没有在 LinkedIn 文档或在线上找到太多相关信息。正如LinkedIn所要求的那样，它可能与上传二进制图像文件有关，但据我所知，我正在上传一个。

编辑：我用来上传图片的 php-curl 如下。$uploadUrl 是从图像寄存器中获取的（步骤 1。）

    $data = [
        'file' => curl_file_create($file, $mimeType)//;
    ];

    ob_start();
    $out = fopen('php://output', 'w');
    $ch = curl_init($uploadUrl);
    curl_setopt($ch, CURLOPT_VERBOSE, true);
    curl_setopt($ch, CURLOPT_STDERR, $out);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    curl_setopt($ch,CURLOPT_USERAGENT,'curl/7.35.0');

    $authorizationHeader = trim("Authorization: Bearer $accessToken");
    curl_setopt($ch, CURLOPT_HTTPHEADER, array($authorizationHeader,"Content-Type: {$mimeType}","X-Restli-Protocol-Version: 2.0.0"));

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_SAFE_UPLOAD, true);
    curl_setopt($ch, CURLOPT_UPLOAD, '1L');
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    $response = curl_exec($ch);

    fclose($out);
    $debug = ob_get_clean();
    print_r($debug);

    $resp_obj = json_decode($response);
    print_r($response);
    curl_close($ch);

资产 API 正在返回：

响应对象是：

                [identifier] => urn:li:userGeneratedContent

            )

    )

)

更新：当我使用命令行 curl 上传图像时它工作正常：

curl -i --upload-file {file} --header "Authorization: Bearer {auth}" {url}

更新：解决方案：

使用 file_get_contents： curl_setopt($ch, CURLOPT_POSTFIELDS, file_get_contents({path-to-your-image));** 

    $ch = curl_init($uploadUrl);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    curl_setopt($ch,CURLOPT_USERAGENT,'curl/7.35.0');
    $authorizationHeader = trim("Authorization: Bearer $accessToken");
    curl_setopt($ch, CURLOPT_HTTPHEADER, array($authorizationHeader,"Content-Type: {$mimeType}","X-Restli-Protocol-Version: 2.0.0"));
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_SAFE_UPLOAD, true);

    curl_setopt($ch, CURLOPT_POSTFIELDS, file_get_contents({path-to-your-image));
    $response = curl_exec($ch);
