如何防止 WebClient 类自动跟随标头中的位置?

How do you prevent the WebClient class from automatically following the location in headers?(如何防止 WebClient 类自动跟随标头中的位置?)

问题描述

在 WebClient 类上可以吗?

Is it possible on the WebClient class?

例如类似:

MyWebClient.AllowAutoRedirect = false; (of HttpWebRequest) 

推荐答案

您可以编写一个自定义 Web 客户端并启用此功能:

You could write a custom web client and enable this functionality:

public class WebClientEx : WebClient
{
    protected override WebRequest GetWebRequest(Uri address)
    {
        var request = (HttpWebRequest)base.GetWebRequest(address);
        request.AllowAutoRedirect = false;
        return request;
    }
}

然后:

using (var client = new WebClientEx())
{
    Console.WriteLine(client.DownloadString("http://google.com"));
}
