ruby​​ - reddit oauth returns 404

Question

を使用してredditから認証トークンを取得しようとしています。私はhereと説明されているredditのスクリプト認証を使用しています。

そのページのカールバージョンは次のようになります。これで私の詳細を入力すると正しく動作し、認証トークンが返されます。

curl -X POST -d 'grant_type=password&username=reddit_bot&password=snoo' --user 'p-jcoLKBynTLew:gko_LXELoV07ZBNUXrvWZfzE3aI' https://www.reddit.com/api/v1/access_token 

ここでは、動作していない認証実装を使用したRubyコードです。ここで

require 'httparty' 
require 'logger' 

class Reddit 
    include HTTParty 
    base_uri 'https://reddit.com' 
    logger ::Logger.new("httparty.log"), :debug, :curl 

    def initialize(client_id, client_secret, username, password, user_agent) 
    @auth = { username: client_id, password: client_secret } 
    @username = username 
    @password = password 
    @user_agent = user_agent 
    end 

    def authenticate() 
    options = { 
     basic_auth: @auth, 
     body: { grant_type: 'password', username: @username, password: @password }, 
     headers: { 'User-Agent' => @user_agent } 
    } 
    self.class.post('/api/v1/access_token', options) 
    end 
end

Answer 1

であるあなたが最初の要求でhttps://reddit.comからhttps://www.reddit.comに301リダイレクトを打ったようです。

HTTPartyがリダイレクトをたどると、POSTの代わりにGET要求が実行されます。

base_uriを代わりに「https://www.reddit.com」に設定してみてください。
