Asp.net Google Drive api将文件名上载为；无标题；

我可以上传文件到谷歌驱动器从我的网站，但我的问题是，它会显示为无标题的文件上传后

如何向上传文件添加或发布标题

谢谢

我的代码：

public string UploadFile(string accessToken, byte[] file_data, string mime_type)
    {
        try
        {
            string result = "";
            byte[] buffer = file_data;
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.googleapis.com/upload/drive/v2/files?uploadType=media");

            request.Method = "POST";

            request.ContentType = mime_type;
            request.ContentLength = buffer.Length;
            request.Headers.Add(HttpRequestHeader.Authorization, "Bearer " + accessToken);

            var stream = request.GetRequestStream();
            stream.Write(file_data, 0, file_data.Length);
            stream.Close();

            HttpWebResponse webResponse = (HttpWebResponse)request.GetResponse();//Get error here
            if(webResponse.StatusCode == HttpStatusCode.OK)
            {
                Stream responseStream = webResponse.GetResponseStream();
                StreamReader responseStreamReader = new StreamReader(responseStream);
                result = responseStreamReader.ReadToEnd();//parse token from result

                var jLinq = JObject.Parse(result);

                JObject jObject = JObject.Parse(jLinq.ToString());

                webResponse.Close();

                return jObject["alternateLink"].ToString();
            }

            return string.Empty;


        }
        catch
        {
            return string.Empty;
        }
    }

不使用google.api DLL就可以做到这一点并不是那么容易。在发送文件的其余部分之前，需要先发送元数据。为此，您需要使用uploadType=multipart

如果你需要评论以外的解释，请告诉我。我费了一个月的劲才把它修好。这几乎和可恢复的上传一样糟糕。
