我正在使用.Net framework 2.0 / jQuery对2.0 Web服务进行Ajax调用。无论我在ajax调用中将contentType设置为什么,该服务始终返回XML。我希望它返回Json!
这里是电话:
$(document).ready(function() {
$.ajax({
type: "POST",
url: "DonationsService.asmx/GetDate",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
// Hide the fake progress indicator graphic.
$('#RSSContent').removeClass('loading');
// Insert the returned HTML into the <div>.
$('#RSSContent').html(msg.d);
}
});
});
这是Fiddler中的请求标头的样子:
POST /DonationsService.asmx/GetDate HTTP/1.1
x-requested-with: XMLHttpRequest
Accept-Language: en-us
Referer: http://localhost:1238/text.htm
Accept: application/json, text/javascript, */*
Content-Type: application/json; charset=utf-8
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; eMusic DLM/4; .NET CLR 2.0.50727)
Host: localhost:1238
Content-Length: 2
Connection: Keep-Alive
Pragma: no-cache
我尝试将contentType设置为'text / json'并获得相同的结果。
这是Web服务方法:
<WebMethod()> _
Public Function GetDate() As String
'just playing around with Newtonsoft.Json
Dim sb As New StringBuilder
Dim sw As New IO.StringWriter(sb)
Dim strOut As String = String.Empty
Using jw As New JsonTextWriter(sw)
With jw
.WriteStartObject()
.WritePropertyName("DateTime")
.WriteValue(DateTime.Now.ToString)
.WriteEndObject()
End With
strOut = sw.ToString
End Using
Return strOut
End Function
这是它返回的内容:
<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://DMS.Webservices.org/">{"DateTime":"11/13/2008 6:04:22 PM"}</string>
有人知道我要Json时如何强制Web服务返回Json吗?
请不要告诉我升级到.Net Framework 3.5或类似的东西(我不是那么愚蠢)。我需要一个2.0解决方案。
