使用 SSL 找不到资源 wcf 服务

Question

我使用 asp.net vb 创建了一个 REST api，我试图通过安全连接 (https) 调用该 api，但出现错误

The resource cannot be found

我可以使用 (http) 调用任何方法，但使用 (https) 我不能。我可以使用（https）访问api（service.svc）的主页，但是功能有问题！下面是我的配置和函数头。

    <system.serviceModel>


   <services>
  <service name="RESTAPI" behaviorConfiguration="MyServiceTypeBehaviors">

    <endpoint address="customBinding" binding="customBinding" bindingConfiguration="basicConfig" contract="RESTAPI"/>

<endpoint address="" behaviorConfiguration="HerbalAPIAspNetAjaxBehavior"
      binding="webHttpBinding" contract="HerbalAPI"  />

    <endpoint contract="RESTAPI" binding="mexHttpBinding" address="mex" />


     </service>

</services>

  <!-- **** Services ****-->


<behaviors>

  <serviceBehaviors>
    <behavior name="MyServiceTypeBehaviors">
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>


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

</behaviors>
 <bindings>
  <customBinding>
    <binding name="basicConfig">
      <binaryMessageEncoding/>
      <httpTransport transferMode="Streamed" maxReceivedMessageSize="67108864"/>
    </binding>
  </customBinding>

</bindings>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"
  multipleSiteBindingsEnabled="true" />

API 类

<ServiceContract(Namespace:="")>
<AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Allowed)>
Public Class RESTAPI
 <OperationContract()>
<WebInvoke(Method:="GET", ResponseFormat:=WebMessageFormat.Json, RequestFormat:=WebMessageFormat.Json)>
Public Function test(ByVal st As String) As JSONResultString
//any code
End Function
End Class

您需要在 web.config 文件中定义一个特殊的绑定配置，以允许 SVC 服务正确绑定 HTTPS 请求。

请看这篇博文：https://weblogs.asp.net/srkirkland/wcf-bindings-needed-for-https

您的服务已经在web.config 中定义，只需添加bindingConfiguration 属性：

<services>
  <service name="TestService">
    <endpoint address="" behaviorConfiguration="TestServiceAspNetAjaxBehavior"
      binding="webHttpBinding" bindingConfiguration="webBindingHttps" contract="TestService" />
  </service>
</services>

然后为webHttpBinding定义特殊绑定设置，修复HTTPS请求的神奇部分是<security mode="Transport" />：

<bindings>
  <webHttpBinding>
    <binding name="webBindingHttps">
     <security mode="Transport">
     </security>
    </binding>
  </webHttpBinding>
</bindings>

这将有效地将服务切换到 HTTPS，但如果您希望 HTTP 和 HTTPS 都可以工作，您需要定义 2 个绑定配置，然后每个服务有 2 个相同的端点，其中一个使用 http bindingConfiguration另一个使用 https bindingConfiguration，如下所示：

<bindings>
  <webHttpBinding>
    <binding name="webBindingHttps">
     <security mode="Transport">
     </security>
    </binding>
    <binding name="webBindingHttp">
      <!-- Nothing special here -->
    </binding>
  </webHttpBinding>
</bindings>

<services>
  <service name="TestService">
    <endpoint address="" behaviorConfiguration="TestServiceAspNetAjaxBehavior"
      binding="webHttpBinding" bindingConfiguration="webBindingHttps" contract="TestService" />
    <endpoint address="" behaviorConfiguration="TestServiceAspNetAjaxBehavior"
      binding="webHttpBinding" bindingConfiguration="webBindingHttp" contract="TestService" />
  </service>
</services>
