Ionic native http plugin error

Hello, I’m trying to make http request using Ionic native http plugin.
i send the request like this:

this.login = {
      Username: this.loginForm.value.userName,
      Password: this.loginForm.value.password
    console.log(this.connection.baseUrl);`${this.connection.baseUrl}/LogOn/LogInMobile`, this.login, {
      "content-type": "application/json",
      "Accept": 'application/json',
      'Access-Control-Allow-Origin': '*',
      'Access-Control-Allow-Headers': 'Content-Type',
      'Access-Control-Allow-Methods': 'GET,PUT,POST,DELETE,OPTIONS'
    }).then(data => {
      let resp = JSON.parse(;
      console.log('resp', data);
      if ( === true) {'userId', resp.Id);'branchId', resp.branch);
      else {
        let message = "error 1";
    }).catch(err => {
      this.errorMessage.errMsg('error 2');

but i always get this error on catch()

This request is working well on Postman.

Hi @aboelhaithem!

Is there any reason why you’re using the HTTP plugin instead of the browser’s XHR or Angular’s HttpClient? Also, the Access-Control headers needed for CORS need to be returned by the server, not sent by the client :wink:

In any case, your server is returning 404 Not Found so you might not be sending the requests to the right endpoint.


First I’d like to thank you. I was using the angular http client first but i faced a problem with CORS and many solutions referred to use Ionic native http instead of angular http and that already worked for me, but when i tried to convert the login function i faced this problem.
What i want to say that the ionic native plugin works well with another post requests.
The 404 url which in the error is not the url which i call.
This request works well on postman.


as a test, try to hard code the url instead of doing this:

this may be your problem.
