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

this look like headers need to be setup but i did by my server with:

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?

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

Please also spend some time to format your post.

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 `Observable`s here, not raw scalars.

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?

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

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)
