做一个REST WCF WebService的电话时坏请求 [英] Bad Request when making a call to a REST WCF WebService

问题描述

我写一个Android应用程序和WCF REST服务从中调用。当我尝试拨打电话，以一定的方法我收到一个错误的请求的消息。在previous测试我设法做到这一点调用及其工作，但在课堂上的一些变化后，我不能试。

I'm writing an Android application and a WCF REST service to call from it. When I try to make a call to a certain method I receive an "Bad Request" message. In a previous test I managed to do this call and its worked, but after some changes in classes I could not again.

这是在服务类：

public class Venda
    {
        public int Cod { get; set; }
        public string Pedido { get; set; }
        public int Cliente { get; set; }
        public int Vendedor { get; set; }
        public string Modo { get; set; }
        public DateTime Data { get; set; }
        public double Total { get; set; }
        public string Observacoes { get; set; }
        public string TipoPagto { get; set; }
        public double Desconto { get; set; }
        public int ST { get; set; }
        public int GF { get; set; }

        public List<DetalheVenda> DetalhesVenda { get; set; }

        public Venda()
        {
            DetalhesVenda = new List<DetalheVenda>();
        }
    }

public class DetalheVenda
    {
        public int Cod { get; set; }
        public string Pedido { get; set; }
        public string Produto { get; set; }
        public double Quantidade { get; set; }
        public double ValorVenda { get; set; }
        public double ValorCompra { get; set; }
        public double ValorVendaMinimo { get; set; }
        public int ST { get; set; }
        public double Desconto { get; set; }
        public int Vendedor { get; set; }
        public int Cliente { get; set; }
        public string Modo { get; set; }
        public DateTime Data { get; set; }
        public string Grade { get; set; }
        public string SubGrade { get; set; }
    }

方法接口和实现：

Method interface and implementation:

[OperationContract]
        [WebInvoke(
            Method = "POST",
            UriTemplate = "AdicionaVenda",
            BodyStyle = WebMessageBodyStyle.WrappedRequest,
            ResponseFormat = WebMessageFormat.Json,
            RequestFormat = WebMessageFormat.Json)]
        void AdicionaVenda(Venda venda);


 //a breakingpoint nor enter here
public void AdicionaVenda(Venda venda)
        {
            repositorio.AdicionaVenda(venda);
        }

这是我送的身体要求JSON：
{文达：
    {鳕鱼：空，Pedido：1.1.56，Cliente：0，Vendedor：1，摩多：A prazo，数据：2014年2月22日 总计0，Observacoes：，TipoPagto：TIPO泰斯特，Desconto：0，ST：1，GF：0，
    \"DetalhesVenda\":[{\"Cod\":null,\"Pedido\":\"1.1.56\",\"Produto\":\"13\",\"Quantidade\":0,\"ValorVenda\":9,\"ValorCompra\":5,\"ValorVendaMinimo\":0,\"ST\":0,\"Desconto\":0,\"Vendedor\":0,\"Cliente\":0,\"Modo\":\"A prazo，数据：2014年2月22日，等级：1级，路基：路基1}]}}

This is the JSON that I send as the body request: {"venda": {"Cod":null,"Pedido":"1.1.56","Cliente":0,"Vendedor":1,"Modo":"A prazo","Data":"2014-02-22","Total":0,"Observacoes":"","TipoPagto":"Tipo Teste","Desconto":0,"ST":1,"GF":0, "DetalhesVenda":[{"Cod":null,"Pedido":"1.1.56","Produto":"13","Quantidade":0,"ValorVenda":9,"ValorCompra":5,"ValorVendaMinimo":0,"ST":0,"Desconto":0,"Vendedor":0,"Cliente":0,"Modo":"A prazo","Data":"2014-02-22","Grade":"grade 1","SubGrade":"subgrade 1"}]}}

推荐答案

其实它不是一个以的DateTime 问题在你的模型类申请，但它是从.NET的东西。

Actually its not a problem with DateTime filed in your model classes but it is something from .NET.

有 。这没有标准的JSON格式。这就是为什么你面对这个问题。有两个方案来解决这个：

There is no standard JSON format of Date.This is why you are facing this problem. There are two solutions for this:

1. 使用 JSON.NET 。

或者，在模型类设置日期类型字符串后来当您收到JSON，解析成日期时间上。

Or, set the type of your date to String in model class and later on when you receive json, parse it into DateTime.
