Troubleshooting: Ionic Cordova's Post Functionality Fails to

I am a newcomer to Hybrid application development, currently utilizing Ionic Cordova for my project. My aim is to implement a POST method within the application.

var url = "http://XXXXXXXXXXXXX.com/XXXX";
var headers = new Headers();
 headers.append("Accept",'application/json');
  headers.append('Content-Type','application/json');
   let options = new RequestOptions({headers : headers});

   let postParams = {
     Name: this.imagename,
     StartDate: this.adstartdate,
     EndDate: this.adEnddate,
     UploadName:this.imagename
  }

// The above code (postParams) seems to not be properly connected with the following code.

 this.http.post(url,postParams,options)
 .subscribe(data =>{
   console.log(data['_body']);
   alert('Success! Entered: '+ data['_body']);
   this.jsonvalue = JSON.stringify(data['_body']);


    alert('Json Value: '+ this.jsonvalue);

 },error =>{

   console.log(error);
   alert('Fail');
 } 

I'm seeking guidance on where I may have faltered in this code. Please overlook any grammatical errors.

To make a successful post request, you must pass a RequestOptions object as a parameter.

For example:

import {RequestOptions} from '@angular/http'

Then create the following RequestOptions object:

let options = new RequestOptions({
               Name: this.imagename,
               StartDate: this.adstartdate,
               EndDate: this.adEnddate,
               UploadName:this.imagename
               });

Now you can use the 'options' variable for the http request.

this.http.post(url,postParams,options)
 .subscribe(data =>{
   console.log(data['_body']);
   alert('Success! Data received: '+ data['_body']);
   this.jsonvalue = JSON.stringify(data['_body']);

    alert('JSON Value: '+ this.jsonvalue);

 },error =>{

   console.log(error);
   alert('Failure');
 }
