我要去哪里错了，呼吁ASMX Web方法从jQuery的？ [英] Where am I going wrong in calling ASMX web methods from jquery?

问题描述

我有一个简单的WebMethod上一个asp.net 2.0应用程序（使用1.0扩展而不是3.5 AJAX扩展）。我试图调用从jQuery的方法，当我这样做是为无数例子表明在互联网上，并在这里的话，我得到一个内部服务器错误消息返回。

I have a simple webmethod on an asp.net 2.0 application (using the 1.0 extensions not the 3.5 ajax extensions). I'm attempting to call the method from jQuery and when I do it as the countless examples show on the Internet and here on SO, I get an Internal Server Error message returned.

下面是我目前的code：

Here's my current code:

[WebMethod]
[ScriptMethod(ResponseFormat=ResponseFormat.Json)]
public string Select(string login)
{
    UserProfile profile = UserProfile.GetUserProfile(login);

    return "{ FirstName: '" + profile.FirstName + "', " +
             "LastName: '" + profile.LastName + "', " +
             "EmailAddress: '" + profile.EmailAddress + "', " +
             "PhoneNumber: '" + profile.PhoneNumber + "' }";
 }

而现在的jQuery的：

And now the jquery:

$.ajax({
    type: "POST",
    url: "Services/ProfileService.asmx/Select",
    dataType: "json",
    data: "{'login':'DOMAIN%5CUSER1'}",
    contentType: "application/json; charset=utf-8",
    success: function(msg){ alert(msg); },
    error: function(xhr){ alert(xhr.statusText);}     
});

WebService的装饰与 [ScriptService] 属性为好。如果我注释掉的contentType，更改数据类型设置为文本，更改数据是一个查询字符串（名称=值），我得到返回的XML适当。

The webservice is decorated with the [ScriptService] attribute as well. If I comment out the contentType, change the dataType to text, and change the data to be a query string (name=value), I get the XML returned appropriately.

我在哪里去了？

更新： 我使用jQuery的V1.3.1和测试均IE6和Firefox 3。我得到一致的结果。

UPDATE: I am using jQuery v1.3.1 and testing in both IE6 and Firefox 3. I'm getting consistent results.

推荐答案

这是我的一部分，一个愚蠢的错误。该问题已得到解决。虽然我包括参考AJAX扩展，我忘了重写的HttpHandler的ASMX服务，以ScriptHandlerFactory类。

This was a stupid mistake on my part. The issue has been resolved. While I included the reference to the AJAX Extensions, I forgot to rewrite the httphandler for ASMX services to the ScriptHandlerFactory class.

添加此解决了问题。

既然我已经得到了一些电子邮件，询问的例子或我如何固定的问题，我写了一篇关于如何做到这一点一应俱全博客文章。

Since I have got some emails inquiring about examples or how I fixed the issue, I wrote a blog post about how to do this soup to nuts.
