错误的请求调用WCF服务Jquery Ajax

Question

我正在尝试为Jquery Ajax的JSON提供WCF服务，但是该方法甚至无法启动，现在返回错误Bad Request。

以下是调用服务，服务接口，服务类，服务Web.config，Global.asax服务的Java脚本代码。

如果访问$ .getJSON的GetData方法有效，但不能使用$ .Ajax，则详细信息。

已经使用AddStudant方法无法正常工作。

谁能告诉我这是怎么回事？

JavaScript的

$（“＃bt”）。click（function（）{

var url =“ http://domain.net/Service1.svc/AddStudant ”; var data = {“ ID”：1，“ Name”：“ Ericsson Alves”}; var jdata = {}; jdata.student =数据；

callAjax（url，'json'，'POST'，函数（结果）{alert（result）;}，JSON.stringify（jdata））; }）;

函数callAjax（ajaxUrl，ajaxDataType，ajaxType，funcSucess，dataValues）{

  $.ajax({ url: ajaxUrl, dataType: ajaxDataType, type: ajaxType, data: dataValues, processdata: true, contentType: "application/json;charset-uf8" }) .done(function (data) { funcSucess(data); }) .always(function (data) { }).fail(function (xhr, status, errorThrown) { alert(xhr.responseText); }); } 

接口

[ServiceContract]
    public interface IService1
    {
        [OperationContract]
        [WebInvoke(Method = "GET",
        BodyStyle = WebMessageBodyStyle.WrappedRequest,
        ResponseFormat = WebMessageFormat.Json)]
        Student GetData(int id);

        [OperationContract]
        [WebInvoke(Method = "POST",
        BodyStyle = WebMessageBodyStyle.WrappedRequest,
        ResponseFormat = WebMessageFormat.Json,
        RequestFormat = WebMessageFormat.Json)]
        Student AddStudant(Student student);

    }

[DataContract]
    public class Student
    {
        [DataMember]
        public int ID { get; set; }
        [DataMember]
        public string Name { get; set; }
    }

服务等级

[AspNetCompatibilityRequirements(RequirementsMode
    = AspNetCompatibilityRequirementsMode.Allowed)]
    public class Service1 : IService1
    {
        [WebInvoke(Method = "GET",
        BodyStyle = WebMessageBodyStyle.WrappedRequest,
        ResponseFormat = WebMessageFormat.Json)]
        public Student GetData(int id)
        {
            return new Student() { ID = id, Name ="Ericsson Alves" };
        }

        [WebInvoke(Method = "POST",
        BodyStyle = WebMessageBodyStyle.WrappedRequest,
        ResponseFormat = WebMessageFormat.Json,
        RequestFormat = WebMessageFormat.Json)]
        public Student AddStudant(Student student)
        {
            return new Student() { ID = student.ID , Name ="Ericsson Alves" };
        }
    }

Answer 1

在ajax请求中将contentType设置为text/plain

Answer 2

尝试发送data而不是jdata ，我想您需要发送的对象是{ "ID": 1, "Name": "Ericsson Alves" }而不是像您目前正在做的那样在另一个对象中发送{student: { "ID": 1, "Name": "Ericsson Alves" }}
