可以直接访问ashx文件后面加参数 xxx.ashx?id=1&name=abc

Answer 5

和普通的一样啊，如果你不用Jquery的话<script type="text/javasccript">
var xmlHttp;
function createXmlRequest()
{
    if(window.ActiveXObject)
    {
        xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
    else if(window.XMLHttpRequest)
        xmlHttp=new XMLHttpRequest();
}
 
function Startreadystate()
{
CreateXmlRequest();
xmlHttp.onreadystatechange=handlerStateChange;
xmlHttp.open("GET","/xxxx.ashx?参数名="+escape(document.getElementById("参数ID").value),true);
xmlHttp.send(null);
}
 
function handlerStateChange()
{
if(xmlHttp.readystate=="4" && xmlHttp.status=="200")
{
    if(xmlHttp.responseText!="")
    {
        document.getElementById("ID").innerText=xmlHttp.responseText;
    }
}
}
</script>

lz问的是C#程序怎么访问.ashx页面吧，WebClient或者HttpWebRequest都可以

Answer 7

        StringBuilder builder = new StringBuilder();
        builder.Append("http://xxx.com.cn/misc.ashx");
        builder.Append("?");
        builder.Append("action=gold");
        builder.Append("&");
        builder.Append("token="+strToken+"");
        HttpWebResponse rsp = null;
        HttpWebRequest req = null;
        req = (HttpWebRequest)WebRequest.Create(new Uri(builder.ToString()));
        req.ContentType = "application/x-www-form-urlencoded";
        req.Accept = "*/*";
        req.Timeout = 30000;//30秒连接不成功就中断 
        req.Method = "GET";
        rsp = (HttpWebResponse)req.GetResponse();
        Stream rspStream = rsp.GetResponseStream();        StreamReader sr = new StreamReader(rspStream, Encoding.GetEncoding("utf-8"));
        result = sr.ReadToEnd();
        sr.Close();
       
        XmlDocument xmlDoc = new XmlDocument();        xmlDoc.LoadXml(result);

Answer 8

  StringBuilder builder = new StringBuilder();

        builder.Append("?"); 
        builder.Append("action=gold"); 
        builder.Append("&"); 
        builder.Append("token="+strToken+"");

        req.ContentType = "application/x-www-form-urlencoded"; 
        req.Accept = "*/*"; 
        req.Timeout = 30000;//30秒连接不成功就中断

        rsp = (HttpWebResponse)req.GetResponse(); 
        Stream rspStream = rsp.GetResponseStream();         StreamReader sr = new StreamReader(rspStream, Encoding.GetEncoding("utf-8")); 
        result = sr.ReadToEnd(); 
        sr.Close(); 
      
        XmlDocument xmlDoc = new XmlDocument();         xmlDoc.LoadXml(result); 

Answer 9

StringBuilder sb = new StringBuilder();
sb.Append("CashChargeStationDailyReport.ashx");
sb.Append("?StationID=" + onPack.StationID);
sb.Append("&ReportDate=" + onPack.ReportDate);HttpWebRequest request = null;
request = (HttpWebRequest)WebRequest.Create(new Uri(sb.ToString()));
请问：最后一行代码出错：无效的 URI: 无法确定 URI 的格式。
怎么写这个参数。
