无法通过 Web 服务获取 URL 中的数据

本文关键字：URL 数据 获取 服务 Web | 更新日期: 2023-09-27 18:37:25

我正在制作网络服务，而不是通过URL获取解析数据WEB服务的代码是这样的。我的服务类

  namespace DataService
 {
   [ServiceContract]
   public interface IService1
  {
     [OperationContract]
    [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedResponse)]
    List<RequestData> GetUser(RequestData data);
    [OperationContract]
    [WebGet(ResponseFormat = WebMessageFormat.Json, UriTemplate = "UsersList/{id}", RequestFormat = WebMessageFormat.Json)]
    RequestData UsersList(string id);
     }

  [DataContract]
   public class RequestData 
   {
    [DataMember] 
    public string Name { get; set; } 
    [DataMember] 
    public int Age { get; set; } 
    [DataMember] 
    public string Address { get; set; }
}

}

这是我的服务 1 类由 Iservice1 类继承

namespace DataService
{
    public class Service1 : IService1
   {
      public List<RequestData> GetUser(RequestData data)
      {
        List<RequestData> list = new List<RequestData>();
        if (data.Name.ToUpper() == "MAIRAJ")
        {
            list.Add(new RequestData
            {
                Name = "Mairaj",
                Age = 25,
                Address = "Test Address"
            });
            list.Add(new RequestData
            {
                Name = "Ahmad",
                Age = 25,
                Address = "Test Address"
            });
            list.Add(new RequestData
            {
                Name = "Minhas",
                Age = 25,
                Address = "Test Address"
            });
        }
        return list;
    }
    public RequestData UsersList(string userId)
    {
        if (userId == "1")
        {
            return new RequestData
            {
                Name = "Mairaj",
                Age = 25,
                Address = "Test Address"
            };
        }
        else
        {
            return new RequestData
            {
                Name = "Amir",
                Age = 25,
                Address = "Test Address"
            };
        }
        }
       }
    }

我在部署 Web 服务后提供此 URL http://116.58.61.180/ADG/Service1.svc确切的 url 应该解析什么来获取数据

这是我的 Web.config

   <?xml version="1.0"?>
  <configuration>
   <system.web>
  <compilation debug="true" targetFramework="4.0" />
   </system.web>
  <system.serviceModel>
   <behaviors>
   <serviceBehaviors>
      <behavior>
      <serviceMetadata httpGetEnabled="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>
  </behaviors>
  <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
   </system.serviceModel>


  <directoryBrowse enabled="true"/>
  </system.webServer>
  </configuration>

无法通过 Web 服务获取 URL 中的数据

我想你只是忘记了web.config中的一些东西： 

<endpointBehaviors>
    <behavior>
        <webHttp helpEnabled="true"/>
    </behavior>
</endpointBehaviors>

和

<protocolMapping>
   <add binding="webHttpBinding" scheme="http" />
</protocolMapping>

如果你不把所有这些东西放在你的web.config中，你将无法让你的服务工作。

完整的Web.config是这样的： 

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>
  <system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5"/>
  </system.web>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
        <endpointBehaviors>
            <behavior>
                <webHttp helpEnabled="true"/>
            </behavior>
        </endpointBehaviors>
    </behaviors>
    <protocolMapping>
        <add binding="webHttpBinding" scheme="http" />
    </protocolMapping>    
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
    <directoryBrowse enabled="true"/>
  </system.webServer>
</configuration>

有关更多详细信息，我几个月前在我的博客上写了一篇关于WCF和REST的文章：

简单的 WCF 和 REST 服务

WCF 和 POST 方法

按照以下步骤操作：

  1. 使用以下属性装饰您的服务类

    [ServiceContract]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1

  2. Web.config 应该看起来像这样

      <?xml version="1.0"?>
    <configuration>
      <system.web>
         <compilation debug="true" targetFramework="4.0" />
      </system.web>
      <system.webServer>
         <modules runAllManagedModulesForAllRequests="true">
            <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
         </modules>
      </system.webServer>
      <system.serviceModel>
        <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
          <standardEndpoints>
            <webHttpEndpoint>
              <standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="true"/>
            </webHttpEndpoint>
          </standardEndpoints>
      </system.serviceModel>
    </configuration>

  3. 您的 Global.asax 应如下所示。

    public class Global : HttpApplication
{
    void Application_Start(object sender, EventArgs e)
    {
      RegisterRoutes();
    }
    private void RegisterRoutes()
    {
    // Edit the base address of Service1 by replacing the "Service1" string below
        RouteTable.Routes.Add(new ServiceRoute("Service1", new WebServiceHostFactory(), typeof(Service1)));
    }
}
