title: MobileFirst Platform JavaScript adapter can't get the parameters through WLResourceRequest
body: <p>I'm using mobilefirst platform v7,  and I send post request using the  WLResourceRequest/sendFormParameters api, however, I can't get the submitted parameters from js adapter side...</p>
  
  <p>belows are sample code:</p>
  
  <pre><code>var resourceRequest = new WLResourceRequest("adapters/businessAdapter/flightsearch", WLResourceRequest.POST);
  var params={
          "flightNum":'mu8899',
          "departCity":'SHA',
          "destCity" :'PEK'
  };
  resourceRequest.sendFormParameters(params).then(
          callSuccess,
          callFailure
  );
  </code></pre>
  
  <p>js adapter code:</p>
  
  <pre><code>function flightsearch(params) {
     WL.Logger.info("get params "+params);
  
  
      var input = {
          method : 'post',
          returnedContentType : 'json',
          path : 'restapi/api/flightsearch',
          body :{
              contentType: 'application/json; charset=utf-8',
              content:params
          },
          headers: {"Accept":"application\/json"} 
      };
  
      return WL.Server.invokeHttp(input);
  }
  </code></pre>
