C#获取页面返回结果(含cookie获取)

直接调用方法，传入登录请求地址

using System;
using System.Net;

private string GetCookie(string url){ 
	HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url);
    myHttpWebRequest.CookieContainer = new CookieContainer();
	myHttpWebRequest.CookieContainer.SetCookies(new Uri(url), "");
    HttpWebResponse myresponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
    return myresponse.Headers["Set-Cookie"];
}

有时候一些网站的数据请求需要登录后才能获取，这时候可以根据上面的方法获取到cookie保存下来，然后再通过下面的方法请求。

using System.IO;

public string GetHtml(string url, string cookieStr)
{ 
	WebRequest wrt = WebRequest.Create(url);
	wrt.Credentials = CredentialCache.DefaultCredentials;
    wrt.Headers.Add("Cookie", cookieStr);
    WebResponse wrp = wrt.GetResponse();
    return new StreamReader(wrp.GetResponseStream(), Encoding.UTF8).ReadToEnd();
}
