c# - 请求中对象的值在wcf服务中始终为null

Question

我有一个 WCF 服务和用于测试该服务的客户端网站。 WCF 服务没有获取对象的值。我已经在网上搜索并修改了我的代码。然而我还没有解决。有人会帮助我吗。提前致谢。

有我的服务:

 [OperationContract]
    [WebInvoke(Method = "POST",
       ResponseFormat = WebMessageFormat.Xml,
        RequestFormat = WebMessageFormat.Json,
       BodyStyle = WebMessageBodyStyle.WrappedRequest,          
       UriTemplate = "BookInfo/")]

    BookingResult Booking(BookInfo bookInfo);


 public BookingResult Booking(BookInfo bookInfo)
    {
        BookingResult result = new BookingResult();            
        if (bookInfo.Name == null)
        {
            result.isSucceed = false;
        }
        else
        {
            result.isSucceed = true;
        }

        return result;
    }

我的网站上有调用服务的方法。

using Booking; //this is WCF service reference
private string callService(BookInfo input)
    {

        string serviceUrl = "http://localhost:1599026/Booking.svc/BookInfo/";            
        string stringPayload = "{\"bookInfo\":[" +JsonConvert.SerializeObject(input) +"]}";           
        WebClient client = new WebClient();
        client.Headers["Content-type"] = "application/json";                    
        client.Encoding = Encoding.UTF8;
        string rtn = client.UploadString(serviceUrl,"POST", stringPayload);
        return rtn;

    }

Answer 1

你的错误信息是从哪里得到的，可以分享给我吗？您是否正确配置和发布了 WCF 网络模式服务？我复制了你的代码并在IIS上托管了web模式的服务，终于成功访问了该方法。我建议你可以暴露默认的GetData()方法，然后测试它是否能正确获取返回结果，然后我们测试强类型方法。

这是我的demo，希望对你有用。

IService1.cs

public interface IService1
{
    [OperationContract]
    [WebGet]
    string GetData(int value);

    [OperationContract]
    [WebInvoke(Method = "POST",
   ResponseFormat = WebMessageFormat.Xml,
    RequestFormat = WebMessageFormat.Json,
   BodyStyle = WebMessageBodyStyle.WrappedRequest,
   UriTemplate = "BookInfo/")]
    BookingResult Booking(BookInfo bookInfo);
}

Service1.svc.cs

public class Service1 : IService1
{
    public BookingResult Booking(BookInfo bookInfo)
    {
        BookingResult result = new BookingResult();
        if (bookInfo==null)
        {
            result.isSucceed = false;
        }
        else
        {
            result.isSucceed = true;
        }
        return result;
    }
    public string GetData(int value)
    {
        return string.Format("You entered: {0}", value);
    }

}
[DataContract]
public class BookInfo
{
    [DataMember]
    public string Name { get; set; }
}
[DataContract]
public class BookingResult
{
    [DataMember]
    public bool isSucceed { get; set; }

网络配置

<system.serviceModel>
<services>
  <service name="WcfService4.Service1" behaviorConfiguration="svbehavior">
    <endpoint address="" binding="webHttpBinding" contract="WcfService4.IService1" behaviorConfiguration="webbehavior">
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"></endpoint>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="svbehavior">
      <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
      <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
      <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
    <behavior name="webbehavior">
      <webHttp />
    </behavior>
  </endpointBehaviors>
</behaviors>
<protocolMapping>
    <add binding="basicHttpsBinding" scheme="https" />
</protocolMapping>    
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />

结果。

获取方法。
