如何使用3-legged Token将文件上传到Autodesk Forge的存储位置？

Question

我已通过创建存储位置API按3脚标记，accessToken和bucketKey生成objectName，如所示。

我想将文件上传到存储位置。我的请求返回'OK 200'状态，但它不会将文件上传到A360，因为我需要。 哪里出错了？如何使用3-legged Token正确地将文件上传到用户的存储位置？

    [HttpGet]
    public JObject UploadFile(string accessToken,string bucketKey,string objectName,string filePath)
    {                      
        var url = String.Format("https://developer.api.autodesk.com/oss/v2/buckets/{0}/objects/{1}", bucketKey, objectName);

        using (var client = new HttpClient())
        {
            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
            var response = client.PutAsync(url, new StreamContent(System.IO.File.OpenRead(filePath))).Result.EnsureSuccessStatusCode();
            System.Diagnostics.Debug.WriteLine(response);
        }

    }

Request必须返回带有创建文件参数的JSON，但返回：
