Question

我正在尝试为Jquery Ajax获取JSON的WCF服务，但是现在甚至不启动该方法返回错误Bad Request。

以下是调用服务，服务接口，服务等级，服务Web.config，Global.asax服务的Java Script代码。

详细说明我是否访问$ .getJSON的GetData方法，但不是$ .Ajax。

已经使用AddStudant方法无法以某种方式工作。

任何人都可以帮我告诉我什么是错的吗？

的JavaScript

$（“＃bt”）。click（function（）{

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

callAjax（url，'json'，'POST'，                   function（result）{                       警报（结果）;                   }，                   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; }
    }

服务类

[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

在您的ajax请求中将public List<Foo> getFoos(List<Bar> bars) { return IntStream.range(0, bars.size()) //you may add .parallel() .mapToObj(idx -> bazUtils.getFoo(bars.get(idx), idx+1)) .collect(Collectors.toList()); }设置为contentType

Answer 2

尝试发送data而不是jdata，我想您需要发送对象{ "ID": 1, "Name": "Ericsson Alves" }，而不是将其发送到您正在执行的其他对象{{1} }

错误的请求调用WCF服务Jquery Ajax
