javascript - 将 json 发送到(不是 REST)WCF 服务

Question

我需要一个 javascript 将对象作为 json 发送到 WCF 服务以保存它。我有javascript:

 <script>
      $(document).ready(function(){

                    $("#submitButton").click(function() {

console.info("executing submitButton click");
TestJSon();
 );
      });
       </script>
        <button type="button" id="submitButton">Save</button>
        <script>
            var varType;
            var varUrl;
            var varData;
            var varContentType;
            var varDataType;
            var varProcessData;          
            //Generic function to call AXMX/WCF  Service        
            function CallService() 
            {
            console.log('called CallService')
                    $.ajax({
                        type        : varType, //GET or POST or PUT or DELETE verb
                        url         : varUrl, // Location of the service
                        data        : varData, //Data sent to server
                        contentType : varContentType, // content type sent to server
                        dataType    : varDataType, //Expected data format from server
                        processdata : varProcessData, //True or False
                        success     : function(msg) {//On Successfull service call
                        ServiceSucceeded(msg);                    
                        },
                        error: ServiceFailed// When Service call fails
                    });
        }

        function ServiceSucceeded(result) {//When service call is sucessful
       alert('Service call succeded');
             varType=null;varUrl = null;varData = null;varContentType = null;varDataType = null;varProcessData = null;     
        }
        function ServiceFailed(result) {
            alert('Service call failed: ' + result.status + '' + result.statusText);
            varType = null; varUrl = null; varData = null; varContentType = null; varDataType = null; varProcessData = null;     
        }



        function TestJSon() {
                varType = "POST";
            varUrl = "http://localhost:56616/bebc179a-3a96-4934-88df-df1ca17da8b1/CountryDataService.svc/SaveObject";
            varData = { player: {'Name': '1' }};
            varContentType = "application/json; charset=utf-8";
            varDataType = "json";
            varProcessData = true;
            CallService();

        }
</script>

这个脚本应该使用WCF的这个方法:

 public void SaveObject(Player player)
        {
             var input = player;
            File.WriteAllText(@"c:\Temp\" + "index.html", input.Name, Encoding.UTF8);
            return player;
        }

在服务接口(interface)上是:

[OperationContract]
        [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json)]
        void SaveObject(Player player);

玩家类:

[DataContract(Name = "Player")]
    public class Player
    {
        private string _name;
        [DataMember]
        public string Name { get { return _name; } set { _name = value; } }     

    }

在我的配置中:

<services>
 <service name="MyCompany.Services.CountryDataService" behaviorConfiguration="CountryProvinceBehavior" >
    <endpoint address="" binding="webHttpBinding" contract="MyCompany.Services.ICountryDataService" behaviorConfiguration="CountryProvinceBehavior"/>
  </service>

   <behaviors>     
      <endpointBehaviors>
        <behavior name="CountryProvinceBehavior">
          <webHttp/>
        </behavior>
      </endpointBehaviors> 
      <serviceBehaviors>
        <behavior name="CountryProvinceBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>          
      </serviceBehaviors>
    </behaviors>     
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true" />
  </system.webServer>

最重要的是——结果:方法 ServiceFailed 已被代码 0 和 statusText - NoTransport 击中也没有交通( fiddler 告诉我)服务地址没问题，因为当我将 json 更改为 jsonp ServiceFailed 时，代码 200 和 statusText 也已命中 - 成功。

还有流量:

请求

GET http://localhost:56616/bebc179a-3a96-4934-88df-df1ca17da8b1/CountryDataService.svc/SaveObject?callback=jQuery1710486683341013641_1342788918981&player%5BName%5D=1&_=1342788921786 HTTP/1.1

    <div id="content">
      <p class="heading1">Service</p>
      <p>Endpoint not found.</p>
    </div>
  </body>
</html>

所以，我需要帮助在我的 WCF 服务中保存这个 Player 对象。我正在使用 Wk8 和 .net 4.0

如有任何帮助，我将不胜感激。

Answer 1

让我们一步一步来，这样您就可以有一个起点。

1. 创建一个新的空 ASP.NET 应用程序

2. 添加模型类

   [DataContract]
   public class Player
   {
       [DataMember]
       public string Name { get; set; }
   }
   

3. 服务契约(Contract):

   [ServiceContract]
   public interface ICountryDataService
   {
       [OperationContract]
       [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
       void SaveObject(Player player);
   }
   

4. 和一个实现:

   public class CountryDataService : ICountryDataService
   {
       public void SaveObject(Player player)
       {
       }
   }
   

5. 添加一个 .svc 端点(CountryDataService.svc):

   <%@ ServiceHost 
       Language="C#" 
       Debug="true" 
       Service="MyService.CountryDataService" 
   %>
   

6. 修改 web.config:

   <system.serviceModel>
       <behaviors>
         <endpointBehaviors>
           <behavior name="CountryProvinceBehavior">
             <webHttp/>
           </behavior>
         </endpointBehaviors>          
           <serviceBehaviors>
               <behavior name="">
                   <serviceMetadata httpGetEnabled="true" />
                   <serviceDebug includeExceptionDetailInFaults="false" />
               </behavior>
           </serviceBehaviors>
       </behaviors>
       <services>
           <service name="MyService.CountryDataService">
             <endpoint 
               address="" 
               binding="webHttpBinding" 
               contract="MyService.ICountryDataService" 
               behaviorConfiguration="CountryProvinceBehavior" />
           </service>          
       </services>
       <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
   </system.serviceModel>
   

7. 添加一个index.htm来消费:

   <!DOCTYPE html>
   <html>
   <head>
       <title></title>
   </head>
   <body>
       <script type="text/javascript" src=" http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
       <script type="text/javascript">
           $.ajax({
               url: 'countrydataservice.svc/saveobject',
               type: 'POST',
               contentType: 'application/json',
               data: JSON.stringify({ player: { Name: 'foo bar'} }),
               success: function (result) {
   
               }
           });
       </script>
   </body>
   </html>
