使用HTTPWebRequest上传到Google云端硬盘非常慢 [英] Uploading to Google Drive using HTTPWebRequest is very slow

问题描述

您好：

在我的项目中，我使用的是将数据上传到Google云端硬盘HttpWebRequest的。由于文件大小很大，我使用Resumable upload。我已经将文件分成5 MB的块并上传了块。  对于相同大小的网页浏览器需要几秒钟的时间
，而申请时间超过2分钟。 

In my project I am uploading data to Google drive using HTTPWebrequest. As the file size is large the I am using Resumable uploading. I have divided file in chunks of 5 MB and uploading the chunks.  For the same size of chunk web browser takes few seconds while application is taking more than 2 mins. 

我已经检查过以下设置，但没有或上传速度变化非常小zh。

I have checked with following settings but there is no or very minimal change in uploading speed

                ServicePointManager.UseNagleAlgorithm = false; 

                System.Net.ServicePointManager.CheckCertificateRevocationList = false;

                ServicePointManager.DefaultConnectionLimit      = 1000;

                System.Net.ServicePointManager.Expect100Continue = false;

                ServicePointManager.UseNagleAlgorithm = false; 
                System.Net.ServicePointManager.CheckCertificateRevocationList = false;
                ServicePointManager.DefaultConnectionLimit      = 1000;
                System.Net.ServicePointManager.Expect100Continue = false;

                  httpRequest.Proxy                  =  null;

                 httpRequest.Proxy                  =   null;

              

 这是我的示例代码。如何提高上传速度？提前致谢。

 Here is my sample code. How can I increase the upload speed? Thanks in advance.

public bool UploadRequest(byte[] docChunk,long StartOffset,long EndOffset)
   {
    HttpWebRequest httpRequest =        (HttpWebRequest)WebRequest.Create(URL);

                   httpRequest.Method= "PUT";

                  httpRequest.ContentLength= docChunk.Length;

                   httpRequest.Headers["Content-Range"] = "bytes " + StartOffset + 
                                                           "-" +EndOffset + "/" +
                                                           FileSize.ToString();

      using (Stream f_ObjHttpStream = httpRequest.GetRequestStream())
                       {                          

                        MemoryStream f_ChunkStream = null;

                        f_ChunkStream = new MemoryStream(docChunk);
                        
                        f_ChunkStream.CopyTo(f_ObjHttpStream);//This line execution takes more than 2 mins

f_ObjHttpStream.Flush（）;

f_ObjHttpStream.Close（）;

f_ChunkStream.Close（）;
}

使用（HttpWebResponse httpResponse =（HttpWebResponse）（httpRequest.GetResponse（）））
{
if（httpResponse.StatusCode == HttpStatusCode.OK）
{
httpResponse.Close（）;

返回f_IsUploaded = true;
}
}
}
}

f_ObjHttpStream.Flush(); f_ObjHttpStream.Close(); f_ChunkStream.Close(); } using (HttpWebResponse httpResponse = (HttpWebResponse)(httpRequest.GetResponse())) { if (httpResponse.StatusCode == HttpStatusCode.OK) { httpResponse.Close(); return f_IsUploaded = true; } } } }

推荐答案

Hello Ruyan，

Hello Ruyan,

对于某些上传方式。很明显，Google公司在优化上传操作方面做了大量工作。除了使用浏览器，您还可以选择谷歌同步客户端，您可以将任何您喜欢的内容拖入和移出Drive文件夹。毫无疑问，您可以通过这些工具快速上传文件。

For some upload ways . it is clear that Google company has done much job to optimize the upload action. Beside using browser you also could choose google sync client you can drag whatever you like into and out of the Drive folder.There is no doubt that you upload file fast by these tools.

对于HTTPWebRequest，它只提供WebRequest类的特定于HTTP的实现。我不是谷歌的工作，我想谷歌公司已经为其他上传方式做了一些速度限制工作。

For HTTPWebRequest , it just provides an HTTP-specific implementation of the WebRequest class. I'm not work for google and I guess that google company has done some speed-limit job for other upload ways.

并且有一些关于使用google drive apis上传的信息，你可以参考它。

And there is some information about upload with google drive apis , you could take reference with it.
