asp.net发送post数据

[QQ641350418]

如下有一个接口
http://api.vs128.com/ajax/api.ashx
它只接收post数据的id,

以下是 asp发送的post数据

set http = Server.CreateObject("MSXML2.XMLHTTP")
	'以异步方式发送数据
	http.open "POST","http://api.vs128.com/ajax/api.ashx",false
	http.setRequestHeader "Content-Type","application/x-www-form-urlencoded"
	http.send("id=1")
	'Result为api接口的响应信息
	'responseBody：			结果返回为无符号整数数组。
	'responseStream：		结果返回为IStream流。
	'responseText ：		结果返回为字符串。
	'responseXML：			结果返回为XML格式数据。

	Result = http.ResponseText
	set http = Nothing

请问asp.net 如果发送post数据

我试过不行的，，

string address = "http://api.vs128.com/ajax/api.ashx";
        string data = "id=1";
        string method = "POST";
        WebClient client = new WebClient();
        string reply = client.UploadString(address, method, data);
        Response.Write(reply);

		WebClient webClient = new WebClient();
		webClient.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
		string s = webClient.UploadString("http://api.vs128.com/ajax/api.ashx", "POST", "id=1");
		Response.Write(s);

3楼正解 指定下Encoding 更好 webClient.Encoding = System.Text.Encoding.UTF8

因为API有IP地址限制 所以只能在以下的FTP里测试 IP：124.173.159.11 user:[e-mail] pass:123456zx http://88bbdan.com/test.asp 代码如下：

<%
    strPostToUrl = "http://www.gzidc.com/api.php"
	postData="c_vtime=20130317005705&c_agentid=9641&c_action=Domain.Whois&c_email=[e-mail]&c_validatestr=1b8c6cbbdfb2284fde810e73c789e456&domain=jtdj%2Enet&year=1&tld=%2Enet&lang=ENG&encoding=ASCII"
	set http = Server.CreateObject("MSXML2.XMLHTTP")
	'以异步方式发送数据
	http.open "POST",strPostToUrl,false
	http.setRequestHeader "Content-Type","application/x-www-form-urlencoded"
	http.send(postData)
	
	Result = http.ResponseText
    response.Write(Result)
	set http = Nothing
	'doPost = Result
%>

能成功 http://88bbdan.com/web.aspx 代码如下：

 WebClient webClient = new WebClient();
        webClient.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
        string s = webClient.UploadString("http://www.gzidc.com/api.php", "POST", "c_vtime=20130317005705&c_agentid=9641&c_action=Domain.Whois&c_email=[e-mail]&c_validatestr=1b8c6cbbdfb2284fde810e73c789e456&domain=jtdj%2Enet&year=1&tld=%2Enet&lang=ENG&encoding=ASCII");
        Response.Write(s);

不能成功 请问为什么

[rayyu1989]

参数里有 encoding=ASCII 指定下编码试试 webClient.Encoding = System.Text.Encoding.GetEncoding("gb2312")
