How to access API from another device? #57

Open shesko opened 8 years ago

shesko commented 8 years ago

Hi, First of all thank you very much for this tutorials, I have learnt a lot from them!

However, I have a problem. I am trying to access the api from my iPhone application and I am having problems on figuring out what the correct address is.

When I run the command rails server -b 0.0.0.0 -p 3000, with an IP such as 130.xxx.xxx.xxx, what links should I use to access an account for example?

I tried api.130.xxx.xxx.xxx/accounts/1 but it doesn't seem to reach my rails app.

How does your routes.rb file looks like?

shesko commented 8 years ago 
require 'api_constraints'

Rails.application.routes.draw do
  devise_for :accounts
  namespace :api, defaults: { format: :json },
                    constraints: { subdomain: 'api' }, path: '/'  do
      scope module: :v1, constraints: ApiConstraints.new(version: 1, default: true) do
        resources :accounts, :only => [:show, :create, :update, :destroy]
        resources :sessions, :only => [:create, :destroy]
      end
  end
end

As you may have noted, I am using accounts instead of users

kurenn commented 8 years ago

You endpoints will be under:

api.application.dev/accounts/

Notice that application is the name of your folder name in case you are using pow or the complete domain.

shesko commented 8 years ago

I know how to access it through pow, however I still don't understand what to use when deployed publicly. Let's assume my domain is www.example.com. What would be the link?

When I try http://api.example.com/accounts/1, the rails server does not receive any request.

kurenn commented 8 years ago

I recommend you use naked domains, otherwise

api.example.com/accounts
``

Remember to send the `Accept` header for the correct version. Let me know how it goes
shesko commented 8 years ago

So, to make sure I use the Accept header I decided to use the following curl command: curl -H 'Accept: application/vnd.app_api.v1' http://api.ww.xx.yyy.zzz:3000/accounts/1

where ww.xx.yyy.zzz is the ip address of my server and the rails app is running on port 3000. The request does not reach my server. On the other hand if I use the following curl command: curl -H 'Accept: application/vnd.app_api.v1' http://ww.xx.yyy.zzz:3000/accounts/1

the server receives the requests and returns an html script representing the default rails page. It seems that the "api" part of the full domain name is not recognised by the app.

kurenn commented 8 years ago

It probably has to be with the www try striping that out....

api.xx.zzz:3000/accounts/1
shesko commented 8 years ago

sorry the ww must have confused you. the ww in http://api.ww.xx.yyy.zzz:3000/accounts/1 is meant to be one of the numbers in the ip address of the server

just think it as 

curl -H 'Accept: application/vnd.app_api.v1' http://api.xxx.xxx.xxx.xxx:3000/accounts/1

where xxx.xxx.xxx.xxx is the server's ip address

kurenn commented 8 years ago

The www is a subdomain for your domain, that is way the Rails app can't find the endpoint, try the curl without the www

shesko commented 8 years ago

I edited my previous comment. please read above. in the actual address I am not writing the www.

kurenn commented 8 years ago

I'm not sure why is that, you get the html response? what response is it?

shesko commented 8 years ago

I get an html error page from my internet provider BT

It is super weird, the port 3000 is open on the server?

shesko commented 8 years ago

Yes it definitely is opened since I get a response from the server when I don't add the api subdomain to the address

kurenn commented 8 years ago

Do you have the subdomain configured?, or created on the server?

shesko commented 8 years ago

That must be the problem. I did not know it needed to be set up. As you may have guess, I am a bit of a newbie in all of this. I will let you know if I manage to make it work

thanks for the help !
