我的jquery看起来像这样，但我尝试将我发送的实际数据作为串行化的json(可以看到)发送到一个具有相同悲伤结果的纯json对象。
$.ajax({
type: "POST",contentType: "application/json; charset=utf-8",url: "ajax/Statistics.svc/Get7DaysStatistics",dataType: "json",data: "{'customerId': '2'}",timeout: 10000,success: function(obj) { updateStatistics(obj.d); },error: function(xhr) {
if (xhr.responseText)
$("body").html(xhr.responseText);
else
alert('unknown error');
return;
}
});
wcf服务如下所示：
[SuppressMessage("Microsoft.Performance","CA1822:MarkMembersAsStatic"),OperationContract]
public string Get7DaysStatistics(string customerId)
{
Debug.WriteLine(customerId);
return "Test done";
}
它放在一个具有以下属性的类中：
[ServiceContract(Namespace = "")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
我不会列出web.config中的配置，以保持这个长消息“短”，但我可以发布，如果有人认为他们可以使用它 – 我只是想强调，我可以调用一个方法，并得到一个结果 – 字符串或者甚至一个json对象，我可以读取，只要我不传递任何数据到wcf服务。
解决方法
data: "{'customerId': '2'}",
至
data: '{"customerId": "2"}',
我已经在本地进行了测试，这就解决了这个问题。
顺便说一下，我使用我在使用内置ASP.NET工具之外的库调用ASMX和WCF服务时经常使用的方法进行了调试。我使用由asp:ScriptReference创建的客户端代理程序调用该服务，然后使用HTTP嗅探器(如HttpFox for FireFox)检查发送到服务器的请求，并将请求与jQuery发送的请求进行比较。看到有什么不同(可能是错误的)与请求。在这种情况下，很明显，POST数据被发送有差异。
