Question

我正在尝试在WCF中使用“POST”方法，但是我不能使用它，我在WCF服务中唯一可以使用的是“GET”方法，但是当我尝试使用“POST”时问题就开始了“发送对象的方法：

这是您的合同

namespace Mywcf
{ 
    [DataContract] 
    public class Person 
    { 
        [DataMember] 
        public string Name { get; set; } 
    } 
}

我的对象：

namespace Mywcf 
{ 
    public class Implementacion : Itest 
    { 
        public string Hello() 
        { 
            return "Hi"; 
        }

        public void AddObject(Person p)
        {
            string Name = p.Name;
            TurnBack(Name);
        }

        public string TurnBack(string Name) 
        {
            return Name;
        }
    }
}

我认为问题出现在合同内的标题中或者当我调用AJAX时。

Answer 1

我认为这是附加json数据的错误方法。

 data: "{'p':" + stringJ + "}",

忽略p作为传递它或以正确的方式连接json stringify。

function Insert(name) {
            var objectPerson = {
                "Name": name
            };
           // var stringJ = JSON.stringify(objectPerson);
            $.ajax({
                url: "http://localhost:83/Mywcf/Service.svc/AddObject",
                dataType: "json",
                data: JSON.stringify(objectPerson),
                type: "POST",
                contentType: "application/json; utf-8",
                success: function(msg) {
                    try {
                        alert(msg);
                    } catch (Exception) {
                        alert(Exception);
                    }
                },
                error: function(result) {
                    alert("Error " + result.status + '' + result.statusText);
                }
            });
        }

@Hameed 是的！，我把它放在这里：

 debugger;
        $.ajax({
            url: "http://localhost:83/WCFPruebaServicio/Servicio.svc/AgregarObjeto",

            data: JSON.stringify(objetoPersona),
            async: false,
            crossDomain: true,
            dataType: "json",
            type: "POST",
            contentType: "application/json; utf-8",
            success: function (msg) {
                try {
                    alert('Si se pudo :) '+msg);
                } catch (Exception) {
                    alert(Exception);
                }
            },
            error: function (result) {
                alert("Error " + result.status + '' + result.statusText);
            }
        });

错误400错误请求AJAX（WCF）
