谷歌OAuth访问令牌

Question

我被OAuth和谷歌弄糊涂了。我花了很长时间才让refresh_token创建一个新的access_token。那就知道refresh_token也过期了？？那又有什么意义呢？

我所需要做的就是持久化一个有效的access_token，以便与连奏一起使用。

下面是我手动输入终端以检索OAUTH代码的内容：

client = OAuth2::Client.new('GA_CLIENT_ID', 'GA_SECRET_KEY', {
        :authorize_url => 'https://accounts.google.com/o/oauth2/auth',
        :token_url => 'https://accounts.google.com/o/oauth2/token'
})
client.auth_code.authorize_url({
       :scope => 'https://www.googleapis.com/auth/analytics.readonly',
       :redirect_uri => 'http://localhost',
       :access_type => 'offline',
       :approval_prompt=> 'force'
}) 

然后在浏览器中手动输入输出的url。我将返回的OAUTH代码导出为env变量并获取访问令牌：

access_token = client.auth_code.get_token(ENV['GA_OAUTH_CODE'], :redirect_uri => 'http://localhost')

然后我可以访问access_token和refresh_token：

   begin
      api_client_obj = OAuth2::Client.new(ENV['GA_CLIENT_ID'], ENV['GA_SECRET_KEY'], {:site => 'https://www.googleapis.com'})
      api_access_token_obj = OAuth2::AccessToken.new(api_client_obj, ENV['GA_OAUTH_ACCESS_TOKEN'])
      self.user = Legato::User.new(api_access_token_obj)
      self.user.web_properties.first # this tests the access code and throws an exception if invalid
    rescue Exception => e
      refresh_token
    end

  end

  def refresh_token
    refresh_client_obj =  OAuth2::Client.new(ENV['GA_CLIENT_ID'], ENV['GA_SECRET_KEY'], {
            :authorize_url => 'https://accounts.google.com/o/oauth2/auth',
            :token_url => 'https://accounts.google.com/o/oauth2/token'
        })
    refresh_access_token_obj = OAuth2::AccessToken.new(refresh_client_obj, ENV['GA_OAUTH_ACCESS_TOKEN'], {refresh_token: ENV['GA_OAUTH_REFRESH_TOKEN']})
    refresh_access_token_obj.refresh!
    self.user = Legato::User.new(refresh_access_token_obj)
  end

一个小时后，我的令牌过期，我必须手动从浏览器重新启动进程！我如何在代码中复制这个？

给你，给你做了点小东西:)

这是一个简单的实现，特别是为了减轻更新令牌的痛苦。

只需确保：

1. 放入您自己的APP_ID和APP_SECRET。
2. 要么只保存您的refresh_token并在每次使用它之前调用refresh_token()，要么每次都使用refresh_token_if_needed()，然后重新保存token和expires_at (很明显，因为只有在需要时才会刷新)。
3. 让我知道结果如何。

。

require 'gmail'
require 'gmail_xoauth'
require 'httparty'

class GmailManager
  APP_ID      = "DDDDDDDDDDDD-SSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS.apps.googleusercontent.com"
  APP_SECRET  = "SSSSSS-SSSSSSSSSSSSSSSSS"

  def refresh_token(refresh_token)
    Rails.logger.info "[GmailManager:refresh_token] refreshing using this refresh_token: #{refresh_token}"
    # Refresh auth token from google_oauth2 and then requeue the job.
    options = {
      body: {
        client_id:     APP_ID,
        client_secret: APP_SECRET,
        refresh_token: refresh_token,
        grant_type:    'refresh_token'
      },
      headers: {
        'Content-Type' => 'application/x-www-form-urlencoded'
      }
    }
    response = HTTParty.post('https://accounts.google.com/o/oauth2/token', options)
    if response.code == 200
      token = response.parsed_response['access_token']
      expires_in = DateTime.now + response.parsed_response['expires_in'].seconds
      Rails.logger.info "Success! token: #{token}, expires_in #{expires_in}"
      return token, expires_in
    else
      Rails.logger.error "Unable to refresh google_oauth2 authentication token."
      Rails.logger.error "Refresh token response body: #{response.body}"
    end
    return nil, nil
  end

  def refresh_token_if_needed(token, expires_on, refresh_token)
    if token.nil? or expires_on.nil? or Time.now >= expires_on
      Rails.logger.info "[GmailManager:refresh_token_if_needed] refreshing using this refresh_token: #{refresh_token}"
      new_token, new_expires_on = self.refresh_token(refresh_token)
      if !new_token.nil? and !new_expires_on.nil?
        return new_token, new_expires_on
      end
    else
      Rails.logger.info "[GmailManager:refresh_token_if_needed] not refreshing. using this token: #{token}"
    end
    return token, expires_on
  end
end
