在 Android 中通过 SSL 使用 WCF 服务

Question

我一直在使用WCF (.svc) 服务，在一个运行良好的 Android 应用程序中，请求格式为JSON ，响应格式为XML 。 几天前，我在 DigiCert 的WCF服务上实现了一个SSL证书（使用我的通配符功能）。 该服务可以从浏览器访问，并且没有显示错误。 下面是WebConfig

<?xml version="1.0"?>
<configuration>
  <configSections>
    <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >

          <behavior name="IntermediateWebService.WebBehavior">
              <serviceMetadata httpsGetEnabled="true" />

              <serviceDebug includeExceptionDetailInFaults="true"/>
          </behavior>
        <behavior>

          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata 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 -->

                  </security>
              </binding>
          </basicHttpBinding>
          <webHttpBinding>
              <binding name="webHttpBindingConfig">
                  <readerQuotas maxStringContentLength="2048000" />
              </binding>
          </webHttpBinding>
      </bindings>
      <services>

          <service behaviorConfiguration="IntermediateWebService.WebBehavior" name="IntermediateWebService.Service1">
              <host>
                  <baseAddresses>
                      <add baseAddress="https://myurl:4445/"/>
                  </baseAddresses>
              </host>
              <endpoint address="" binding="basicHttpBinding" contract="IntermediateWebService.IService1" behaviorConfiguration="WebBehavior" bindingConfiguration="secureHttpBinding" />
          </service>
          <!--<service name="IntermediateWebService.Service1">
               <endpoint address=""
      binding="basicHttpBinding"
      bindingConfiguration="secureHttpBinding"
      contract="IntermediateWebService.IService1"/>



          </service>-->
      </services>
      <serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
  </system.serviceModel>
 <system.webServer>
     <validation validateIntegratedModeConfiguration="false"/>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>
</configuration>

所以现在在使用相同的 Android 代码时，响应总是

The server cannot service the request because the media type is unsupported.

我试过使用 SSL Factory，也试过不使用它。

HttpClient client = getHttpsClient(new DefaultHttpClient()); //new DefaultHttpClient();

            HttpPost get = null;
            commandType = params[0].toString();
            if ("Login".equals(params[0])){

                JSONStringer img = new JSONStringer()
                        .object()
                        .key("value")
                            .object()
                                .key("username").value(params[1].toString())
                                .key("pwd").value(params[2].toString())
                                .key("channelID").value(params[3].toString())
                            .endObject()
                        .endObject();
                        StringEntity se = new StringEntity(img.toString());

                get = new HttpPost("https://" + serverIP + ":" + serverPort + "/Service1.svc/auth");
                //get.setHeader("User-Agent", "com.app.new");
                get.setHeader("Accept", "application/json");
                get.setHeader("Content-Type", "application/json");
                get.setEntity(se);

当我探索状态代码 415 返回的错误时， WCF服务以某种方式不接受该请求作为有效的JSON ，因此通过在 svc 标记中添加以下属性来解决问题

Factory="System.ServiceModel.Activation.WebServiceHostFactory"

这是完整的标记

<%@ ServiceHost Language="C#" Debug="true" Service="IntermediateWebService.Service1" CodeBehind="Service1.svc.cs"
Factory="System.ServiceModel.Activation.WebServiceHostFactory" %>
