Using the javascript fetch api to perform a POST request

Question

I would like to reproduce the behavior of this cURL request :

➜  % curl --data "" https://api.t411.ch/auth
{"error":"User not found","code":101}

In this case, the server send me back JSON.

The code I use in Javascript is :

fetch('https://api.t411.ch/auth/', {
    method: 'POST'
}).then(response => {
  return response.json();
}).then(datas => {
  console.log(datas);
});

With that, I get a parsing json error, so, I decided to return response.text() instead of response.json()

The console.log(datas) prints : string(5) "1.2.4" Service 'view' wasn't found in the dependency injection container

It's the same string that I get when I access to the url : https://api.t411.ch/auth with my browser (GET request).

That means that my javascript code send a GET request, even with the method: 'post'

What am I doing bad ?

PS: I think it's not related at all, but I use es6/jsx transpiled by babel in an electron project.

Thanks

Word of warning: this is experimental javascript and poorly supported. Don't use it for anything other than fiddling around, just use a standard XMLHttpRequest. — Damon

Your code is trying to POST to https://api.t411.ch/auth/. It should be https://api.t411.ch/auth instead. This should work fine:

fetch('https://api.t411.ch/auth', {
    method: 'POST'
}).then(response => {
  return response.json();
}).then(datas => {
  console.log(datas);
});
