换一种方式写了页面：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net;
using System.Text.RegularExpressions;
using System.Text;
public partial class Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
public static string getHtml(string url, params string[] charSets)
{
try
{
string charSet = null;
if (charSets.Length == 1)
{
charSet = charSets[0];
}
WebClient myWebClient = new WebClient(); //创建WebClient实例myWebClient
myWebClient.Credentials = CredentialCache.DefaultCredentials;
byte[] myDataBuffer = myWebClient.DownloadData(url);
string strWebData = Encoding.Default.GetString(myDataBuffer);
//获取网页字符编码描述信息
Match charSetMatch = Regex.Match(strWebData, "<meta([^<]*)charset=([^<]*)", RegexOptions.IgnoreCase | RegexOptions.Multiline);
string webCharSet = charSetMatch.Groups[2].Value;
if (charSet == null || charSet == "")
charSet = webCharSet;
if (charSet != null && charSet != "" && Encoding.GetEncoding(charSet) != Encoding.Default)
{
strWebData = Encoding.GetEncoding(charSet).GetString(myDataBuffer);
}
else
{
strWebData = Encoding.GetEncoding("utf-8").GetString(myDataBuffer);
}
return strWebData;
}
catch (Exception e) { return ""; }
}
protected void Button1_Click(object sender, EventArgs e)
{
//Response.Write(getHtml("https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=wx6f952ddf4d761d06&corpsecret=Pm1rRxFph7ceeAZZIHuZts6lYkx8O_t0FsoK057WfB6tPI6VzON1nXeYpjeJClDC"));
Response.Write(getHtml("https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=wx6f952ddf4d734506&corpsecret=gfjhguyfkjl867tuyhoi09hkjnoiui"));
}
}
在本地调试有返回结果，而放到远程服务器上，就什么都没有，也不出错。
疯了，要！！！
