private string requestget(string theurl)
{
Uri lcUri = new Uri(theurl);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(lcUri);
string page;
try
{
//request.KeepAlive = false;
//request.ProtocolVersion = HttpVersion.Version10;
request.Method = "GET";
//request.ContentType = "application/x-www-form-urlencoded";
//request.Proxy = WebProxy.GetDefaultProxy();
//request.AllowAutoRedirect = true;
//request.MaximumAutomaticRedirections = 10;
//request.Timeout = (int)new TimeSpan(0, 0, 60).TotalMilliseconds;
//request.UserAgent = "mozilla/4.0 (compatible; msie 6.0; windows nt 5.1)";

HttpWebResponse res = (HttpWebResponse)request.GetResponse();

Stream st = res.GetResponseStream();
StreamReader sr = new StreamReader(st, Encoding.Default);
page = sr.ReadToEnd();
sr.Close();
res.Close();
}
catch(Exception ee)
{
page = "fail message : " + ee.Message;
}
return page;
}

我网上找了这么个方法，高手们看看对不？

public string PostLogin(string strURL, string strArgs, string strReferer)

恩，就是用 HttpWebRequest

[tkscascor]

嗯. 如果是调用页面 就是上面的代码了, 你参照一下就行了.
其实如果是要引入别人的页面, 如果不做处理的话,, 镶嵌一个iframe可以偷懒...

[godhuang]

上面1星和4星高手的有没有联系方式

[godhuang]

在这里也说不清楚，给你们发消息了，看到留个言，谢谢

[阿非]

有什么问题

[大笨蛋]

用webservice吧.

[inmyownsky1]

楼主用下ajax

[godhuang]

请求的服务器页面是个普通的页面，不是webservice

[godhuang]

如果不用ajax的话要怎么处理

[tkscascor]

我怎么觉得你这是脱了裤子放屁,,, 都后台代码了,直接运行 那个页面要干的事情..

[godhuang]

正因为不知道怎么写代码所以问大家，如果有更好的解决方案那我跟欢迎

[tkscascor]

a a页面做b页面的事情不就行了吗?
b function d(returnvalue)

[godhuang]

如果两个页面是我自己同一个程序那简单了，可以用楼上的做，问题是两个页面根本没关系的，就是接口问题啊

[tkscascor]

额. 你调用接口 ? 调用页面?

[大笨蛋]

接口...不是webservice么...- -!
