C＃得到的WebClient摆脱连接头的 [英] C# get rid of Connection header in WebClient

问题描述

我使用的是C＃中使用WebClient的（）。

我是测试出来被送到什么头，我注意到下面的头会自动添加。

 连接：保持活动
  

有什么办法去除呢？

<类=h2_linDIV>解决方案

我已经遇到了同样的问题，今天上午。

$ B：关于飞碟双向的提示之后，就可以通过传递的HttpWebRequest 到 Web客户端通过继承它来实现
$ b

 类MyWebClient：Web客户端
 {
保护覆盖的WebRequest GetWebRequest（URI地址）
 {
的WebRequest请求= base.GetWebRequest（地址）; 
如果（请求的HttpWebRequest）
 {
（要求为HttpWebRequest的）.KeepAlive = FALSE; 
} 
返回请求; 
} 
} 
  

现在发送标题将包括连接：关闭

I'm using the C# using the WebClient().

I was testing out what headers are sent, and I noticed that the following header is automatically added.

Connection : Keep-Alive

Is there any way to remove this?

解决方案

I had ran into the same issue this morning. Following on Skeet's hint, it can be achieved by passing HttpWebRequest to WebClient by inheriting it:

class MyWebClient : WebClient
{
    protected override WebRequest GetWebRequest(Uri address)
    {
        WebRequest request = base.GetWebRequest(address);
        if (request is HttpWebRequest)
        {
            (request as HttpWebRequest).KeepAlive = false;
        }
        return request;
    }
}

Now sent headers will include Connection : close
