复杂的参数调用.NET Web服务 [英] Calling .net web service with complex parameters

问题描述

我已经看到了与WCF在asp.net接受之一参数JSON Web服务的例子很多。我需要我的服务的方法来接受许多参数和返回像这样的列表;

I have seen many examples of json web services with WCF in asp.net that accept one in-parameter. I need my service method to accept many parameters and return a list like this;

这是我的Service.svc：

This is my Service.svc:

public class Car
{
    public string Title;
    public int Number;
}

[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

public class Service
{

    [OperationContract]
    [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
    public List<Car> GetCarById(int userid, string password , List<Cars> carlist)
    {
        //Doing some stuff here
    }
}

在我的web.config：

In my web.config:

<system.serviceModel>
   <behaviors>
       <endpointBehaviors>
             <behavior name="ServiceAspNetAjaxBehavior">
                 <enableWebScript />
             </behavior>
       </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
   <services>
         <service name="Service">
             <endpoint address="" behaviorConfiguration="ServiceAspNetAjaxBehavior"
 binding="webHttpBinding" contract="Service" />
          </service>
  </services>
  </system.serviceModel>

如何，如果我想通过这些参数，我把这个服务？当我尝试打电话与PARAMS用户ID，密码和卡洛斯的方法，他们都是空。这是我送 HTTP：//localhost/Service.svc/GetCarById 称为应用程序中使用POST菲德勒：

How can I call this service if I want to pass all these parameters? When I try to call the method with the params userid, password and carlist, they are all null. This is what I send to http://localhost/Service.svc/GetCarById using POST in an application called Fiddler:

HEADERS:
Host: localhost
Content-Length: 136
Content-Type: application/json; charset=utf-8

BODY:
{"d":{"password":"test","userid":123,"carlist":[{"__type":"Car","Number":1,"Title":"BMW"},{"__type":"Car","Number":2,"Title":"Honda"}]}}

响应为：{D：空}该方法返回卡洛斯，所以我知道调用该方法，而且卡洛斯为空。如果我改变了方法返回例如错误的字符串我找回来，所以我知道该方法被调用。

The response is: {"d":null} The method is returning carlist, so I know the method is called and that carlist is null. If I change the method to return a string for example "Error" I get that back, so I know the method is called..

你有一个想法是什么，我做错了？

Do you have an idea what I'm doing wrong?

推荐答案

终于找到了解决办法：

从更改：

[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]

要刚：

[WebInvoke]

然后我叫不最初的D的服务，一切都运行完美！

And then I called the service without the initial "d", everything works perfect!
