【问题描述】：
我一直在使用WCF (.svc) 服务一段时间，其请求格式为JSON，响应格式为XML 在运行正常的Android 应用程序中。几天前，我在 DigiCert 的 WCF 服务上实现了一个用于 SSL 目的的证书（使用我的通配符功能）。该服务可从浏览器访问，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" >
<section name="IntermediateWebService.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</sectionGroup>
</configSections>

<compilation debug="true" targetFramework="4.0" />

<behavior>

</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.
我尝试过使用 SSL Factory，但也没有使用它。
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);
【问题讨论】：
-
目标android平台是否支持tls版本？
-
尝试将此标头用于请求“Content-Type”、“text/xml; charset=utf-8”
-
您是否尝试过从浏览器以外的其他设备发出请求并看到它正常工作？例如，如果您使用的是 Google Chrome，请尝试名为“Postman RestClient”和“Advanced RestClient”的插件。查看它是否与您在 Java 代码中设置的标题和
POST正文一起使用。我要解决的问题是，弄清楚这是否是 Android/Java 的问题。如果它仍然有效，请尝试用OkHttp替换您的 HTTP 客户端，看看是否有区别。您也可以向我们公开您的服务，如果您愿意，我们可以“试驾”它;-)
