Http Post AngularJS to Ionic v2

I am new to Ionic 2 and am trying to migrate an old application made in v1 now to v2. I’m trying to do a POST to a service developed in C #, specifically WCF, but I get an error in doing so and it’s that the data types I send are not the ones the service receives (JSON or XML). Similar error occurred when I started with ionic v1 that was solved like this:

         method: 'POST',
         url: url,
         data: JSON.stringify({ dato: 11 }),
         dataType: "json",
         contentType: "application/x-www-form-urlencoded"

But I get the same error I received earlier. The service if it receives data of type JSON since it is working correctly in the version with AngularJS

    let data = JSON.stringify({ dato: 11 });
    let headers = new Headers({ 'Content-Type': 'application/x-www-form-urlencoded'});
    let options = new RequestOptions({ headers: headers });, data, options)
    .subscribe(data => {
    }, error => {

I’m baffled as to what content type the backend wants. You say you’re giving it www-form-urlencoded, but then seem to be feeding it JSON.

Yes, but why in AngularJS does it work? If I set it to receive only JSON also fails.

If you set your backend to receive JSON, the following should work:, {dato: 11})

not working, Change the content type to application / json and my service will configure it so that it would receive JSON as request data and it will not work either. But since postman YES

You do not have to be so verbose with Angular’s Http client. You don’t need to explicitly set content types. You do not need to manually stringify things. I would concentrate my effort on fixing the backend to be able to handle JSON, as that will pay off for all your other requests.

I think the error is not on the side of the backend, because with Angularjs if it works accordingly.

Good luck with that, then.

I retract !, the problem was the backend. I do not understand why, but I had to leave a STREAM object as a request parameter and then deserialize it in the WebService. I stay with the doubt because in AngularJS worked but with Angular2 not. :stuck_out_tongue:
