带有json的Android WCF服务

Question

I have a created a WCF service which is used by android. It returns a json string but the actual string data sent by server code is different as accessed.

My Web.Config

<?xml version="1.0"?>
<configuration>

  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>
  <system.web>
    <compilation debug="true" strict="false" explicit="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5"/>
  </system.web>
  <system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="httpBehavior">
          <webHttp />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior>

          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>

          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service name="WcfAndroid.Service1">
        <endpoint address=""
            behaviorConfiguration="httpBehavior"
            binding="webHttpBinding"
            contract="WcfAndroid.IService1" />

      </service>
    </services>
    <protocolMapping>
        <add binding="webHttpBinding" scheme="https" />
    </protocolMapping>    
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
     <directoryBrowse enabled="true"/>
  </system.webServer>

</configuration>

And My WCF Service Interface :

<ServiceContract()>
Public Interface IService1

     <OperationContract()> _
        <WebGet(UriTemplate:="GetText", BodyStyle:=WebMessageBodyStyle.WrappedRequest, responseformat:=WebMessageFormat.Json, RequestFormat:=WebMessageFormat.Json)> _
        Function GetText() As String

 End Interface

I am returning a constant string from service for testing :

Public Function GetText() As String Implements IService1.GetText
    '' GetjsonString()   returns   {"id": 100,"name": "item X","active": true}
    Return GetjsonString()
End Function

GetjsonString() function returns String {"id": 100,"name": "item X","active": true}

But when service is called it returns :

{\\"id\\": 100,\\"name\\": \\"item X\\",\\"active\\": true}

I don't know Why it is not returning the actual string?

Answer 1

I an not really familiar with language so I am not pretty sure how that function works. Do something like this:

string.replaceAll("\\", "")

to get rid of "\\";

What happened with your string is that it have escaped ".

If this is not enough, and clearly this method has flaws, there is an answer to similar problem: wcf forces chars escaping in response
