Ionic2 Post Services

How can you post data that requires a JSON object as the parameter (parameters if you think about it).

let var url = ...
let jsonObject = ...
let headers = ...., JSON.stringify(jsonObject), {headers: headers})

So after, how do I work with the data?

However you need to inside the subscribe onnext block., JSON.stringify(jsonObject), {headers: headers})
  .map((response) => response.json())
  .subscribe((json) => {console.log(json)});

Thanks, you are really helping me out and I appreciate it. However, I have a little problem, anytime I post data (the server requests a JSON object), I get an Error 400 (which I found out to mean that the server could not receive the data in the format it wanted).
I set some headers and got a new error; Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote
resource at (Reason: CORS preflight
channel did not succeed).
Can someone please review my code and see what I did wrong?

var url = “”;
var headers = new Headers({
‘Content-Type’: ‘application/json’,
‘Accept’: ‘application/json’
var data = ‘, password:123456a’;, JSON.stringify({data}), {headers: headers}).subscribe(
data => {console.log(“Worked”)},
error => {console.log(“Did not work”)},

are you found solution for this?

Your data doesn’t seems to be a valid JSON object.

var data = ', password:123456a';

You can check your json object with JSONLint

Correct json format is

{ "email": "", "password": "123456a" }

And you could remove JSON.stringify() function i think.
