如何 POST 和 jquery 到 WCF

Question

我在从 jquery 调用 WCF 服务时遇到问题。我得到的错误是

415 Cannot process the message because the content type 'application/json; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'.

Service1.cs

public class Service1 : IService1
{
    public string GetData(int value)
    {
        return string.Format("You entered: {0}", value);
    }

    public string Authenticate(string data)
    {
        return "1";
    }
}

IService1

[ServiceContract]
public interface IService1
{
    [OperationContract]
    string GetData(int value);

    [OperationContract]
    [WebInvoke(Method = "POST",
        ResponseFormat = WebMessageFormat.Xml,
        RequestFormat = WebMessageFormat.Xml,
        BodyStyle = WebMessageBodyStyle.Bare,
        UriTemplate = "auth")]

    string Authenticate(string data);

}

    <script>
        $(document).ready(function () {
            var tests = "test";
            $.ajax({
                cache: false,
                type: "POST",
                async: false,
                url: "http://localhost/TestService/Service1.svc/auth",
                data: '{"data": "' + tests + '"}',
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                processData: true,
                success: function (msg) {
                    alert('success');
                 }
            });
        });

我也尝试为此方法设置以下参数，但没有成功

    ResponseFormat = WebMessageFormat.Json,
    RequestFormat = WebMessageFormat.Json,
    BodyStyle = WebMessageBodyStyle.Wrapped,

当您托管服务时，请确保您的 svc 看起来像

<%@ ServiceHost Language="C#" Debug="true" Service="Service" Factory="System.ServiceModel.Activation.WebServiceHostFactory"
