通过GET方法与jQuery调用ASP.NET Web服务功能 [英] Calling ASP.NET web service function via GET method with jQuery

问题描述

我试图调用使用jQuery通过GET方法，Web服务的功能，但有一个问题。这是一个Web服务code：

I'm trying to call web service function via GET method using jQuery, but having a problem. This is a web service code:

[WebService(Namespace = "http://something.com/samples")]
[ScriptService]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class TestWebService  : System.Web.Services.WebService {
    [WebMethod]
    public string Test2()
    {
        string result = null;

    try
        {
            result = "{'result':'success', 'datetime':'" + DateTime.Now.ToString() + "'";
        }
        catch (Exception ex)
        {
            result = "Something wrong happened";
        }

        return result;
    }

}

这是我调用该函数的方式：

That's the way I call the function:

$.ajax({ type: "GET",
         url: "http://localhost/testwebsite/TestWebService.asmx/Test2",
         data: "{}",
         contentType: "application/json",
         dataType: "json",
         error: function (xhr, status, error) {
             alert(xhr.responseText);
         },
         success: function (msg) {
             alert('Call was successful!');
         }
     });

方法调用成功，但结果字符串被覆盖的XML标签，就像这样：

Method is called successfully, but result string gets covered by XML tags, like this:

<string>
{'result':'success', 'datetime':'4/26/2010 12:11:18 PM'
</string>

和我得到的，因为这一个错误（错误处理程序被调用）。有谁知道什么可以做什么呢？

And I get an error because of this (error handler is called). Does anybody know what can be done about this?
