c# - WCF Web 服务客户端没有端点监听

Question

我正在尝试使用 JSON 创建一个 WCF Web 服务，并在 ASP .NET 中与客户端一起使用我的 WCF Web 服务器已启动并运行在 IIS 上托管，我已检查浏览器，获取 JSON 响应。

这是服务器 web.config 文件:

<?xml version="1.0"?>
<configuration>
  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true"/>
  </appSettings>
  <system.web>
    <!--<compilation debug="true" targetFramework="4.5"/>
    <httpRuntime targetFramework="4.5"/>-->
    <compilation debug="true"/>
  </system.web>
  <system.serviceModel>
    <services>
      <service name="WcfServiceApp.Service1">
        <endpoint address="../Service1.svc" binding="webHttpBinding" contract="WcfServiceApp.IService1" behaviorConfiguration="webBehaviour"/>
      </service>
    </services>

    <behaviors>
      <serviceBehaviors>
        <behavior >
          <!-- 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="webBehaviour">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <protocolMapping>
      <add binding="basicHttpsBinding" scheme="https"/>
    </protocolMapping>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
  </system.serviceModel>
  <system.webServer>
    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*"/>
        <add name="Access-Control-Allow-Headers" value="Content-Type, Accept"/>
      </customHeaders>
    </httpProtocol>
    <directoryBrowse enabled="true"/>
  </system.webServer>
</configuration>

之后，我在 ASP .NET 中创建了一个 Web 应用程序客户端来使用 WCF Web 服务。我在客户端添加了 WCF web 服务引用，但是

Visual Studio 2012 not updating client web.config

.我在 stackoverflow 中发现了一些东西对于我的客户 web.config

客户端 web.config

<?xml version="1.0"?>
<configuration>
  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true"/>
  </appSettings>
  <system.web>
    <!--<compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5"/>-->
    <compilation debug="true"/>
  </system.web>
  <system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="webby">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <client>
      <endpoint address="http://localhost/WCFService/Service1.svc" name="Service1" binding="webHttpBinding" 
                contract="ServiceReference1.IService1" behaviorConfiguration="webby"/>
    </client>
  </system.serviceModel>
</configuration>

calling Service from Client

protected void Button1_Click(object sender, EventArgs e)
        {
            string result;
            string input = tbInput.Text;
            ServiceReference1.Service1Client client = new ServiceReference1.Service1Client();
            try
            {
                result = client.GetData(input);
                lbResult.Text = result;
                client.Close();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }

        }

但是当我尝试从 Web 服务读取时，出现异常

There was no endpoint listening at http://localhost/WCFService/Service1.svc/GetData that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

Inner Exception: The remote server returned an error: (404) Not Found."}

我怀疑它是我的 web.config 文件中的配置问题，但不确定是什么导致了这个问题。

谢谢，阿肖克

Answer 1

您正在为您的服务使用 WebHttpBinding。所以基本上这是一个 REST 服务。所以你不能添加 Service Reference 因为 REST 服务不公开任何元数据，你需要通过 HTTP 动词查询资源，比如 GET 或 POST 左右。

试一试:

var req = (HttpWebRequest)WebRequest.Create("your endpoint");
var data_to_send = Encoding.ASCII.GetBytes("some data");
using (var _temp = req.GetRequestStream())
{
    _temp.Write(data_to_send, 0, data_to_send.Length);
}    

var res = req.GetResponse();

或者你可以选择:

var req = new HttpClient().PostAsync("your url", new StringContent(JsonConvert.SerializeObject("your params")));

同时在您的 endpointBehavior 中启用一些属性以捕获更具体的异常详细信息。
