c＃中的http Webrequest [英] http Webrequest in c#

问题描述

你好

我写了一个ac＃desktop app，它使用webrequest / response将大型记录发布到远程网站。



当我在本地测试应用程序，将我的localhost网站指定为我的网址，该应用程序正常工作，但当我尝试连接到远程（实时）网站时，应用程序变得非常慢：上传2,000条记录需要两天以上。



我需要一个更可靠，更快捷的方式来发送这些记录。

（nb：我使用Backgroundworker进行多线程处理）

下面是我的代码的副本：



< pre lang =cs> public string PostDataToWeb（string postData，string url）

{

string retu;

WebRequest request = WebRequest.Create（url）;

request.Method =& quot ; POST& quot ;;

byte [] byteArray = Encoding.UTF8.GetBytes（postData）;



request.ContentType =&am p; quot; application / x-www-form-urlencoded& quot ;;



request.ContentLength = byteArray.Length;



使用（Stream dataStream = request.GetRequestStream（））

{

dataStream.Write（byteArray，0，byteArray.Length）;

}

使用（WebResponse response = request.GetResponse（））

{

retu =（（（HttpWebResponse）回复）.StatusDescription）;

}

返回retu;

}< / pre>





我现在将上述方法包含在循环中，循环遍历所有记录的数据表并逐行发送。



感谢预期。

hello
I wrote a c# desktop app that use webrequest/response to post large records to a remote website.

when i test the app locally, specifying my localhost site as my url, the app works fine but when i try to connect to a remote (live) website the application becomes very slow:it takes more than two days to upload 2,000 records.

Please I need a more reliable and faster way to send this records.
(n.b.:I am using Backgroundworker to multithread)
below is a copy of my code:

<pre lang="cs">public string PostDataToWeb(string postData, string url)
{
string retu;
WebRequest request = WebRequest.Create(url);
request.Method = &quot;POST&quot;;
byte[] byteArray = Encoding.UTF8.GetBytes(postData);

request.ContentType = &quot;application/x-www-form-urlencoded&quot;;

request.ContentLength = byteArray.Length;

using (Stream dataStream = request.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
}
using (WebResponse response = request.GetResponse())
{
retu = (((HttpWebResponse)response).StatusDescription);
}
return retu;
}</pre>


I now included the above method in a loop that loop through a datatable for all the records and send them row by row.

thanks in anticipation.

推荐答案

如果它在本地更快，那么你的网络速度就是问题。除了使数据更小外，没有什么能比它更快。如果你拉链并发送拉链怎么办？

If it's faster locally, then your network speed is the issue. Nothing is going to make it faster except making your data smaller. What if you zip it and send a zip ?
