Question

我已经遵循Auth0 for Rails API here中的快速入门指南，但是向我的Rails API发送可验证的请求始终返回500.标题中有一个JWT，我相信它是有效的，因为复制它到JWT.io，将我的私钥粘贴到＆＃34;秘密＆＃34;输入，然后单击＆＃34; secret base64 encoded＆＃34;显示＆＃34;已验证＆＃34;。

以下相关代码：

请求信息：

Did you mean?  authenticate):

        def request_params
          params.require(:feedback).permit(:data)

end

user.rb

class User < ActiveRecord::Base
  has_secure_password

  def self.from_token_payload payload
    # Returns a valid user, `nil` or raise
    # e.g.
    #   self.find payload["sub"]
  end
end

schema.rb

  create_table "users", force: :cascade do |t|
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.string   "auth_id"
  end

  create_table "visitor_ratings", force: :cascade do |t|
    t.integer  "data",       null: false
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
  end

我根据Auth0论坛中的this帖子更改了Knock的knock.rb配置文件中的一些变量。

Knock.setup do |config|

  config.current_user_from_token = -> (claims) { User.find_or_create_by(auth_id: claims['sub']) }

  config.token_audience = -> { Rails.application.secrets.auth0_client_id }

  config.token_secret_signature_key = -> {
      secret = Rails.application.secrets.auth0_client_secret
      secret += '=' * (4 - secret.length.modulo(4))
      Base64.decode64(secret.tr('-_', '+/'))
    }

end

application_controller.rb的一部分

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  before_action :authenticate, only: :testie

  protect_from_forgery with: :exception

  respond_to :json

  # Knock is used for user JWT requests
  include Knock::Authenticable

  def angular
    render 'layouts/application'
  end

  private

    def reply(message, status)
      respond_to do |format|
        format.json  { render :json =>  {:message => message}, status: status}
      end
    end

end

写完之后，我认为问题可能与目前不属于用户模型的VisitorRating模型有关，但我是Rails的新手并且不确定细节。

我认为您的应用是在12月6日之后创建的。如果是这样，您的config / initializers / knock.rb应该看起来像

Knock.setup do |config|
  config.token_audience = -> { Rails.application.secrets.auth0_client_id }
  config.token_secret_signature_key = -> { Rails.application.secrets.auth0_client_secret }
end

请注意，令牌密码不是base64编码的：https://github.com/nsarno/knock/issues/149和https://github.com/nsarno/knock/issues/146

您的app / models / user.rb看起来应该像

class User < ApplicationRecord
  def self.from_token_payload(payload)
    self.find_or_create_by(auth_id: payload['sub'])
  end
end

您的用户不应该有密码，但from_token_payload需要实际从该有效负载中获取用户。

除此之外，请确保删除控制器中的重复内容（可能不是app / controllers / application_controller.rb中的before_action :authenticate）。

在使用Knock的Rails 4中无法获得Auth0 JWT身份验证
