Omniauth2 设计 Coinbase 策略

Omniauth2 Devise Coinbase strategy

我正在使用 Devise 使用 Google 和 CoinBase oauth2 策略构建一个应用程序。我几乎完全遵循了 Devise oauth 说明,但我仍然无法使用 CoinBase 进行身份验证。我在登录时遇到的错误是 Authentication failure! invalid_credentials: OAuth2::Error, invalid_client: Client authentication failed due to unknown client, no client authentication included, or unsupported authentication method.。通过 Google 的身份验证在开发和生产模式下均能完美运行。以下是每个适用的文件:

config/initializers/devise.rb

config.omniauth :google_oauth2, ENV['google_id'], ENV['google_secret']
config.omniauth :coinbase, ENV['coinbase_id'], ENV['coinbase-secret']

OmniAuth.config.logger = Rails.logger if Rails.env.development?

controllers/users/omniauth_callbacks_controller.rb

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController

  def coinbase
    @user = User.from_omniauth(request.env["omniauth.auth"])

    if @user.persisted?
      sign_in_and_redirect @user
      set_flash_message(:notice, :success, :kind => "Coinbase") if is_navigational_format?
    else
      session["devise.coinbase_data"] = request.env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end

  def google_oauth2
    @user = User.from_omniauth(request.env["omniauth.auth"])

    if @user.persisted?
      sign_in_and_redirect @user
      set_flash_message(:notice, :success, :kind => "Google") if is_navigational_format?
    else
      session["devise.google_data"] = request.env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end

  def failure
    redirect_to root_path
  end
end

models/user.rb

class User < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable, :async,
     :recoverable, :rememberable, :trackable, :validatable, 
     :omniauthable, omniauth_providers: [:google_oauth2, :coinbase]

  def self.from_omniauth(auth)
    where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
      user.email = auth.info.email
      user.password = Devise.friendly_token[0,20]
    end
  end

  def self.new_with_session(params, session)
    super.tap do |user|
      if (data = session["devise.google_data"] && session["devise.google_data"]["extra"]["raw_info"]) || (data = session["devise.coinbase_data"] && session["devise.coinbase_data"]["extra"]["raw_info"])
        user.email = data["email"] if user.email.blank?
      end
    end
  end

我一直在试图找出可能触发失败的原因,我所想到的只是 omniauth-coinbase gem 可能不再受支持。还有其他人 运行 在 CoinBase 上使用 oauth2 遇到困难吗?

我在这个项目上遇到了死胡同,但我确实找出了问题的根源。 Coinbase 只允许你重定向到 https 域,如果你使用本地主机,这是一个问题。

解决方案是为本地域设置 SSL 证书(我不具备这方面的专业知识)或使用 ngrok 之类的服务。
