Rails-Gem Instagram-关于访问令牌和沙箱的问题

Question

I need to put on a website the complete instagram feed of my customer. I have tried several ways to access to instagram and get the whole feed, but I get some errors.

Using the gem "instagram" (the easiest and simplest method) i got the following error when I try to get the access token.

Instagram::BadRequest: POST https://api.instagram.com/oauth/access_token/: 400: OAuthException: Matching code was not found or was already used.

I tried to follow the indication on the instagram documentation https://www.instagram.com/developer/authentication/ using my browser and I can get the access token, but I am not able to do the http calls manually in ruby.

I need to download all the data and keep it inside my database (as I always done) so I need everything in the controller.

my code is very simple:

accessToken = Instagram.get_access_token(Instagram.client_id, :redirect_uri => CALLBACK_URL)
client = Instagram.client(access_token: accessToken)
response = client.user_recent_media

#other code to cycle inside posts and put everything in db

i'm sure to have included the same redirect_url in my instragram registration app and in my code.

Answer 1

As shown in the sample application in the gem's repo , you will need to call authorize_url first:

 Instagram.authorize_url(:redirect_uri => CALLBACK_URL)

and then you will get request on the CALLBACK_URL , where you should have an action with the code that you provided:

 response = Instagram.get_access_token(params[:code], :redirect_uri => CALLBACK_URL)
 client = Instagram.client(:access_token => response.access_token)    
 # do stuff with the client

Answer 2

SOLVED! I have misunderstood the usage of the api.

I got my access token following this https://elfsight.com/blog/2016/05/how-to-get-instagram-access-token/

and i can access my posts using in my model:

access_token  = Instagram.access_token
client = Instagram.client(access_token: access_token)
response = client.user_recent_media

and in my config file:

Instagram.configure do |config|
config.client_id     = "CLIENT_ID"
config.client_secret = "CLIENT_SECRET"
config.access_token  = "ACCESS_TOKEN"
end

thanks a lot for your support

您应在omniauth.auth哈希中处理回调时获得令牌：request.env ['omniauth.auth'] ['credentials'] ['token']
