從asp.net Webservice生成無效的JSON？

任何人都可以引導，下面哪些錯誤生成的JSON代碼是通過asp.net web服務的方法生成的。從asp.net Webservice生成無效的JSON？

--------------------------- 
Message from webpage 
--------------------------- 
Error: Invalid JSON: <?xml version="1.0" encoding="utf-8"?> 

<string xmlns="http://tempuri.org/">[{"id:" '1',"title:" 'Event1',"start:" 1310236200,"end:" 1310236200,"allDay:"true,"description:" 'Event1'},{"id:" '3',"title:" 'Event2',"start:" 1309804200,"end:" 1309804200,"allDay:"true,"description:" 'Event2'},{"id:" '4',"title:" 'Event5',"start:" 1311705000,"end:" 1311705000,"allDay:"true,"description:" 'Event5'},{"id:" '5',"title:" 'Event3',"start:" 1309006800,"end:" 1309006800,"allDay:"false,"description:" 'Event3'},{"id:" '6',"title:" 'Event4',"start:" 1310495400,"end:" 1310495400,"allDay:"true,"description:" 'Event4'},{"id:" '7',"title:" 'Time Event1',"start:" 1312144200,"end:" 1312174800,"allDay:"false,"description:" 'Time Event1'},{"id:" '8',"title:" 'save1',"start:" 1312309800,"end:" 1312309800,"allDay:"true,"description:" 'save1111'},{"id:" '9',"title:" 'today',"start:" 1311273000,"end:" 1311273000,"allDay:"true,"description:" 'today'}]</string>

我覺得你的問題是在錯誤的請求服務結束。通過ASP.NET AJAX

<asp:ScriptManager ID="_scriptManager" runat="server"> 
    <Services> 
    <asp:ServiceReference Path="Service/WebService1.asmx" /> 
    </Services> 
</asp:ScriptManager> 

<script type="text/javascript"> 
    $(document).ready(function() { 
    Test.Service.WebService1.HelloWorld(OnComplete); 

    function OnComplete(result) { 
     alert(result.value); 
     alert(result.name); 
    } 
    } 
</script>

namespace Test.Service 
{ 
    [WebService(Namespace = "http://tempuri.org/")] 
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] 
    [ToolboxItem(false)] 
    [ScriptService] 
    public class WebService1 : WebService 
    { 
    [WebMethod] 
    public object HelloWorld() 
    { 
     // ! return anonymous object. It cannot be serialized to xml and orients solely to json-request. 
     return new { value = 12345, name = "John" }; 
    } 
    } 
}

通過jQuery中獲取數據

<script type="text/javascript"> 
    $(document).ready(function() { 
    $.ajax({ 
     type: "POST", 
     contentType: "application/json; charset=utf-8", 
     url: "Service/WebService1.asmx/HelloWorld", 
     data: "{}", 
     dataType: "json", 
     success: function (data) { 
      alert(data.d.value); 
      alert(data.d.name); 
     } 
    }); 
    } 
</script>

獲取數據：請參閱工作代碼：

詭計問題？

因爲這是XML，JSON不是。

因此錯誤

這是真的。但是如何在asp.net中爲JSON調用webservice？ –

什麼是真正奇怪的，我是，我XMLHttpRequest是返回XML，並通過JSON.parse（）來與谷歌Chrome瀏覽器被成功解析，但在Android瀏覽器的股票（這我還帶領相信運行WebKit的），我得到一個「意外的令牌非法「錯誤。它是這個原因，我認爲，如果它的工作對我的開發機瀏覽器，它會在Android瀏覽器工作了。 –

也許您的請求指定了「application/xml」或「text/xml」內容類型，請確保您指定的「application/json」內容類型來代替。

您可以使用調試代理像Fiddler或Web瀏覽器的開發工具（如螢火蟲，Chrome瀏覽器開發工具）驗證這一點。

如果你告訴我們的JavaScript代碼，我們可以可能找到的東西，否則請確保您使用jQuery.getJSON或指定「contentType: "application/json; charset=utf-8"」如果你使用jQuery.ajax（你需要實際的字符集）。
