【问题描述】：

我正在使用 oauth2 gem 进行谷歌登录身份验证。我的代码看起来像

omniauth.rb

OmniAuth.config.logger = Rails.logger
require "omniauth-google-oauth2"
Rails.application.config.middleware.use OmniAuth::Builder do
  provider :google_oauth2, 'secret-client-id', 'secret-number', {client_options: {ssl: {ca_file: Rails.root.join("cacert.pem").to_s}}}
end

我的 routes.rb

  get 'auth/:provider/callback', to: 'sessions#create'
  get 'auth/failure', to: redirect('/')

我的观点

 <%= link_to "Sign in with Google", "/auth/google_oauth2", id: "sign_in" %>

我在这个页面之后得到这个 URL

我哪里出错了？

【解决方案1】：

尝试将令牌添加到omniauth 初始化程序：

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :google_oauth2, "id", "secret", {
    client_options: {ssl: {ca_file: Rails.root.join("cacert.pem").to_s}},
    scope: 'email profile',
    access_type: 'online',
    setup: (lambda do |env|
      request = Rack::Request.new(env)
      env['omniauth.strategy'].options['token_params'] = {:redirect_uri => 'http://.../auth/google_oauth2/callback'}
    end)
}
end
