What I try to do is send data to php using codeigniter and receive a response from the server to manage a login.

in a few words send an email and a password to php using URLSearchParams in the service part

my login method:

login( email:string, pass:string ){

// console.log(email, pass);


let data = new URLSearchParams();
data.append('correo', email);
data.append('contrasena', pass);

// console.log(data);

let url =  'http://localhost:90/generales/rest/index.php/login/prueba';

return this.http.post( url, data ).map( resp=>{

  let data_resp = resp;
  console.log(data_resp);
        
});

}

when i’m trying this i have this error

POST http://localhost:90/generales/rest/index.php/login/prueba 404 (Not Found)

this look like headers need to be setup but i did by my server with:
Header(“Access-Control-Allow-Headers”, “*”);
Header(“Access-Control-Allow-Methods: PUT, GET, POST, DELETE, OPTIONS”);
Header(“Access-Control-Allow-Headers: Content-Type, Content-Length, Accept-Encoding”);

Your post is unreadable - did you look at it?

What is your ionic info output?

santanajensy · August 3, 2018, 9:27pm

What I try to do is send data to php using codeigniter and receive a response from the server to manage a login.

in a few words send an email and a password to php by email using URLSearchParams in the service part

my ionic version
ionic@4.0.3

Sujan12 · August 3, 2018, 9:28pm

Not what I asked for. Run ionic info in your project directory.

Please also spend some time to format your post.

rapropos · August 3, 2018, 9:35pm

You are badly abusing the map operator. It is designed solely for transforming data from format A to format B. None of the error-handling, view layer stuff, or state modification (assigning to object properties) should be in there. I would even argue error-handling and alert popping doesn’t belong in your service class at all, but at the very least you need to get it out of map and into tap, if you insist on storing state in the provider.

The way you are storing that state is also problematic, because clients have no way of (a) knowing when it is valid or (b) being informed of changes. You should be exposing Observables here, not raw scalars.

ok i really understand that now but i’m new using ionic. pls may you write me an example or please edit my code. i will appreciate that.

santanajensy · August 3, 2018, 9:58pm

ok thank you so much. i just did

Sujan12 · August 3, 2018, 10:02pm

Still no ionic info output in sight.

ok please check now again

Sujan12 · August 3, 2018, 10:22pm

Seems your server is returning an error 404 when you POSt to this URL.
Can you manually POST there using a tool like Postman or Insomnia?

santanajensy · August 3, 2018, 10:53pm

yes, i’m using postman.

postman can see everything but when i’m use my service is the problem.

Sujan12 · August 3, 2018, 11:00pm

That doesn’t make sense. If the requests are identical, they have to be responded in the same way as well.

santanajensy · August 3, 2018, 11:10pm

ok thank you so much

santanajensy · August 3, 2018, 11:20pm

yes i know i will put a picture to show you

php code:
public function prueba_post() {
$data = $this->post();

    $this->response($data);

}

Sujan12 · August 3, 2018, 11:26pm

And the request your app is creating, screenshot of the dev tools of your browser with the relevant tabs selected?

santanajensy · August 3, 2018, 11:39pm

yes it is the devtool postman

Sujan12 · August 3, 2018, 11:41pm

You didn’t understand what I said.

We need to see the request your app is sending and results in a 404. We have to be able to compare. (Actual request, not the code that generates the request)

santanajensy · August 3, 2018, 11:45pm

ok i’m sorry.

this is my php code function:

public function prueba_post() {
$data = $this->post();

    $this->response($data);

}
