我想从客户端(JavaScript)异步发送POST到服务器端(ASP.Net),带有2个参数:numeric和long formated string。
我理解长格式字符串必须有encodeURIComponent()才能传递它。
我的麻烦是我想在主体请求中嵌入长编码字符串,然后在服务器端从C#打开它。
拜托,你能帮助我吗?我用ajax,xhr,Request.QueryString [],Request.Form [],......搞错了。

首先,创建一个HTTPHandler:
using System.Web;
public class HelloWorldHandler : IHttpHandler
{
public HelloWorldHandler()
{
}
public void ProcessRequest(HttpContext context)
{
HttpRequest Request = context.Request;
HttpResponse Response = context.Response;
//access the post params here as so:
string id= Request.Params["ID"];
string longString = Request.Params["LongString"];
}
public bool IsReusable
{
// To enable pooling, return true here.
// This keeps the handler in memory.
get { return false; }
}
}
然后注册:
<configuration>
<system.web>
<httpHandlers>
<add verb="*" path="*.ashx"
type="HelloWorldHandler"/>
</httpHandlers>
</system.web>
</configuration>
现在使用jQuery Ajax调用它:
$.ajax({
type : "POST",
url : "HelloWorldHandler.ashx",
data : {id: "1" , LongString: "Say Hello"},
success : function(data){
//handle success
}
});
我刚刚测试过,开箱即用。这就是我所说的:
<script language="javascript" type="text/javascript">
function ajax() {
$.ajax({
type: "POST",
url: "HelloWorldHandler.ashx",
data: { id: "1", LongString: "Say Hello" },
success: function (data) {
//handle success
}
});
}
</script>
<input type="button" id="da" onclick="ajax();" value="Click" />
