What is the best approach for submitting a form with data through a POST request in an Ionic application?

I am facing an issue while trying to make a POST request in Ionic for submitting a form with an array of data. Surprisingly, it works perfectly fine when I test it on POSTMAN.

https://i.sstatic.net/t8sEG.jpg

Although I attempted to use this form, it did not yield the desired results:

  submitRegistration(value):void{

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

let link = 'http://apidata.com/';

let myData = {
  fos_user_registration_form: [{
    _token: this.data.token,
    username: value.usuario,
    email: value.correo,
    plainPassword: [{
      first: value.password,
      second: value.confirmPassword
    }],
    userLocalization: value.municipio}
  ]};

console.log(myData);

this.http.post(link, myData, options)
  .subscribe(data => {
    this.data.response = data["_body"];
  }, error => {
    alert("Oooops!");
  });

}

Could someone kindly provide assistance?

Answer №1

Make sure to convert the data into a string before submitting, give this a shot

this.http.post(link, JSON.stringify(myData), options)
  .subscribe(data => {
    this.data.response = data["_body"];
  }, error => {
    alert("Oops, something went wrong!");
  });

This method should work effectively

Answer №2

At last, the solution has been discovered (by me). Below is the code snippet:

  function submitRegistration(value) {
    var headers = new Headers();
    let options = new RequestOptions({ headers: headers });
    headers.append("Content-Type", 'application/x-www-form-urlencoded');

    let link = 'http://APIREST.com/';

    let myData = 'fos_user_registration_form[_token]=' + encodeURI(this.data.token);
    myData += '&fos_user_registration_form[username]=' + encodeURI(value.username);
    myData += '&fos_user_registration_form[email]=' + encodeURI(value.email);
    myData += '&fos_user_registration_form[plainPassword][first]=' + encodeURI(value.password);
    myData += '&fos_user_registration_form[plainPassword][second]=' + encodeURI(value.confirmPassword);
    myData += '&fos_user_registration_form[userLocalization]=' + encodeURI(value.city);

    console.log(myData);

    this.http.post(link, myData, options)
      .subscribe(data => {
        this.data.response = data["_body"];
        console.log(data);
      }, error => {
        console.log("Oops!");
      });
  }

}
