authentication ionic2

but, this is not work.
ill look it up.

What doesn’t work? “does not work” is not a good description.

when push login button, nothing.
i expected to move tabs page.

but,when push login button, alwasy this happen.

 127.0.0.1 - - [31/May/2017 20:35:19] "OPTIONS /api/login HTTP/1.1" 200 10

i dont need “OPTIONS” method. i want “PUT” method. but not work…

in spite of adding this config, still not work.

{
  "name": "auth",
  "app_id": "",
  "type": "ionic-angular",
  "proxies": [{
    "path": "/api/login",
    "proxyUrl": "http://localhost:3000"
  }]
}

what should i do…?

This is how browsers work. You can read all about it here: Cross-Origin Resource Sharing (CORS) - HTTP | MDN If the OPTIONS request is successful, it should then do the desired request.

And again:

is not a error description we can work with.

thanks your reply.
yes… options request is always successful
but, idont know why next page is not showing up when i click login button.

mmm…ill look it up arround “token”.

thanks !!
