Ruby - reddit oauth 返回 404

Question

我正在尝试使用 HTTParty 从 reddit 获取身份验证令牌。我正在使用 reddit 的脚本身份验证，这在 here 中进行了解释。

该页面的 curl 版本如下所示。如果我在其中输入我的详细信息，那么它可以正常工作并返回身份验证令牌。

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

这是我的 ruby​​ 代码，其中的身份验证实现不起作用。

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

这是我的日志

Answer 1

您似乎在初始请求中遇到了从 https://reddit.com 到 https://www.reddit.com 的 301 重定向。

当 HTTParty 遵循重定向时，它会执行 GET 请求而不是 POST（应该如此）。

尝试将您的 base_uri 改为“https://www.reddit.com”。
