Ruby on rails 缺少必需的客户端标识符-Google日历

我遵循本教程在Rails应用程序上实现google日历。

config/initializer/omiauth.rb

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :google_oauth2,
           ENV['my_long_key'],
           ENV['my_other_key'],
           { scope: "userinfo.email, calendar" }
end

class ExampleController < ApplicationController
  before_action :authenticate_candidate!, except: [:redirect]
  before_action :authenticate_interviewer!, except: [:client_options]


  def redirect
    client = Signet::OAuth2::Client.new(client_options)
    redirect_to client.authorization_uri.to_s
  end

  private

  def client_options
    {
      client_id: ENV["google_client_id"],
      client_secret: ENV["google_client_secret"],
      authorization_uri: "https://accounts.google.com/o/oauth2/auth",
      token_credential_uri: "https://accounts.google.com/o/oauth2/token",
      scope: Google::Apis::CalendarV3::AUTH_CALENDAR,
      redirect_uri: callback_url

    }
  end
end

我还生成了config/secrest.yml（它不存在）：

控制器/example_controller.rb

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :google_oauth2,
           ENV['my_long_key'],
           ENV['my_other_key'],
           { scope: "userinfo.email, calendar" }
end

class ExampleController < ApplicationController
  before_action :authenticate_candidate!, except: [:redirect]
  before_action :authenticate_interviewer!, except: [:client_options]


  def redirect
    client = Signet::OAuth2::Client.new(client_options)
    redirect_to client.authorization_uri.to_s
  end

  private

  def client_options
    {
      client_id: ENV["google_client_id"],
      client_secret: ENV["google_client_secret"],
      authorization_uri: "https://accounts.google.com/o/oauth2/auth",
      token_credential_uri: "https://accounts.google.com/o/oauth2/token",
      scope: Google::Apis::CalendarV3::AUTH_CALENDAR,
      redirect_uri: callback_url

    }
  end
end

但是

当我去：

我得到：

缺少所需的客户端标识符。

最有可能的是，您的google凭据中的env变量没有传递到进程（即

env[“google\u client\u id”]

或者其他变量）

谢谢，我如何验证它们是否已传递？如果我从

example\u controller

中放入

client

，我会得到以下结果：

。…}>

您可以使用

put“google\u client\u id:{ENV[“google\u client\u id”]}

例如，如果控制台中为空，那么它就不会传递到我应该放在哪个文件中

config/initializer/omiauth.rb

？您可以将其放在

def client_options

方法的第一行，但通常是在Rails过程中执行的任何文件中
