找不到引用契约的默认终结点元素 - 托管WCF

Question

我在这个网站http://wswob.somee.com/wobservice.svc上有一个wcf服务。

我尝试用我的winform应用程序消费该服务。当我创建该服务的实例时，我收到以下错误：

com.somee.wobservice.IwobserviceClient myservice = new com.somee.wobservice.IwobserviceClient();

错误：

Could not find default endpoint element that references contract
'com.somee.wobservice.Iwobservice' in the ServiceModel client configuration section. This 
might be because no configuration file was found for your application, or because no 
endpoint element matching this contract could be found in the client element.

我搜索并修改了我的app.config文件：

<system.serviceModel>
<behaviors>
  <endpointBehaviors>
    <behavior name="wobservice">
      <clientVia />
    </behavior>
  </endpointBehaviors>
</behaviors>

<client>
  <endpoint
      name="wobservice"
      address="http://wswob.somee.com/wobservice.svc"
      binding="webHttpBinding"
      contract="com.somee.wobservice"
      behaviorConfiguration="wobservice" />
</client>

</system.serviceModel>
</configuration>

我的wcf文件夹中的web.config：

<system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true"/>

          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>

        <endpointBehaviors>
            <behavior name="Web">
                <webHttp/>
            </behavior>
        </endpointBehaviors>
    </behaviors>

      <serviceHostingEnvironment  multipleSiteBindingsEnabled="true">
          <baseAddressPrefixFilters>
              <add prefix="http://wswob.somee.com/"/>
          </baseAddressPrefixFilters>
      </serviceHostingEnvironment>

      <bindings>
          <webHttpBinding>
              <binding>
                  <security mode="None" />
              </binding>
          </webHttpBinding>
      </bindings>

      <protocolMapping>
           <add binding="basicHttpsBinding" scheme="https"/>
           <add binding="basicHttpBinding" scheme="http"/>
      </protocolMapping>

      <services>
           <service name="wobwcf.wobservice">
              <endpoint address="" 
                        binding="webHttpBinding" 
                        behaviorConfiguration="Web" 
                        contract="wobwcf.Iwobservice" />
           </service>
      </services>
   </system.serviceModel>

我不是很确定哪一部分出了错。我对WCF的经验仅有一周...

Answer 1

将您的库项目中的app.config中的system.serviceModel部分复制到web.config文件中，并刷新服务引用。另请参阅此答案。

当我设置地址为"http://wswob.somee.com/"或者"http://wswob.somee.com/wobservice.svc"时，服务无法工作... - Jackie Ngo Anh Khoi

终于搞定了！！！我设置了绑定，然后是客户端。合同应该像这样：contract="com.somee.wobservice.Iwobservice" - Jackie Ngo Anh Khoi

Answer 2

在客户端的web.config文件中添加以下内容来定义客户端；

 <system.serviceModel>
  /////
 <client>
         <endpoint  address="referencedurl"
          binding="webHttpBinding" bindingConfiguration=""
          contract="MemberService.IMemberService"
          name="MemberServiceEndPoint"
          behaviorConfiguration="Web">
      </endpoint>
 </client> 
////
 </system.serviceModel>

AND服务引用名称必须与接口前缀相同。 contract="引用名称.IMemberService"

Answer 3

在您的WCF服务web.config文件中添加“WSHttpBinding”端点，如下所示。

 <endpoint address="web" behaviorConfiguration="jsonBehavior" binding="webHttpBinding" bindingConfiguration="webHttpBindingWithJsonP" contract="DataService.IDataService"/>
 <endpoint address="" binding="wsHttpBinding" bindingConfiguration="wsHttpBinding" contract="DataService.IDataService"  />

在你的app.config文件中编写以下代码。

<system.serviceModel>
<bindings>
  <wsHttpBinding>
    <binding name="WSHttpBinding_IDataService" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647">
      <security mode="None" />
    </binding>
  </wsHttpBinding>
</bindings>
<client>
  <endpoint address="http://localhost/pricedataservice/DataService.svc" binding="wsHttpBinding"
      bindingConfiguration="WSHttpBinding_IDataService" contract="DataService.IDataService"
      name="WSHttpBinding_IDataService" />
</client>

我相信这会解决你的问题，下面的博客将帮助你了解WCF服务中不同类型的绑定。

是的，那正是我所做的，但我没有使用JSON... 非常感谢。 - Jackie Ngo Anh Khoi

这与JSON无关，但您在WCF服务web.config文件中没有添加“wsHttpBinding”端点，这就是为什么您会遇到错误的原因。 - Rachit Patel
