Php Quickblox：用户图像或化身通过API成功上传，但未在Quickblox管理面板中预览？

内容部分图像状态中的Quickblox管理面板已上载，但nethier图像正在预览，AWS（amazons3）链接也不起作用

步骤1-使用quickblox帐户（主帐户）创建会话，并从响应中获取会话令牌

步骤2-使用用户凭据和会话令牌登录API用户

步骤3-创建一个blob，并从响应中提取所有blob信息参数，并生成一个json数组

步骤4-上传用户图像/化身并获得响应

步骤5-上传声明的文件

步骤6-已将blob id连接到API用户

这是我的全部代码，告诉我我做错了什么：

注意：登录凭据不是真实的

在curl请求之前，您应该创建新的CURLFile对象
并在$fields数组中使用它

        $file_ext  = mime_content_type($profile_pic);
        $file_path = realpath($profile_pic);
        $curl_file = new CURLFile($file_path, $file_ext, $profile_pic);

        $fields = array
        (
            "Content-Type"          => $content_type,
            "Expires"               => $expires,
            "acl"                   => $acl,
            "key"                   => $key,
            "policy"                => $policy,
            "success_action_status" => $success_action_status,
            "x-amz-algorithm"       => $x_amz_algorithm,
            "x-amz-credential"      => $x_amz_credential,
            "x-amz-date"            => $x_amz_date,
            "x-amz-signature"       => $x_amz_signature,
            "file"                  => $curl_file
