如何在Ruby中通过Instagram API获取用户名和/或ID？

Question

I'm not exactly sure how to call methods such as screen name in order to get the username and/or id with Instagram and Ruby:

username = Instagram.configure do |config|
  config.client_id = "YOUR_CLIENT_ID"
  config.client_secret = "YOUR_CLIENT_SECRET"
  # For secured endpoints only
  #config.client_ips = '<Comma separated list of IPs>'
end

puts username.user

Answer 1

First, you need to give a link that will take you to Instagram, and you will be asked to enter your username and password, and get verified there.

<%= link_to 'Click here to go to Instagram', '/oauth/connect' %>

In your routes file,

get '/oauth/connect' => 'users#connect'

In your UsersController class,

def connect
  redirect Instagram.authorize_url(:redirect_uri => CALLBACK_URL)
end

CALLBACK_URL is crucial here; this is the link Instagram will redirect you once you enter your username and password on Instagram site. When Instagram will hit on your CALLBACK_URL , you can do the following to get the parameters you have asked in your question:

client = Instagram.client(:access_token => session[:access_token])
user = client.user
username = user.username
