API命中誤差給出 - 完成500內部服務器錯誤，類型錯誤（未繳的隱式轉換成字符串）

Question

我的routes.rb -

Rails.application.routes.draw do 
    root 'welcome#index' 

    namespace :api, defaults: { format: :json } do 
    namespace :v1 do 
     get "https://stackoverflow.com/users/:cv_id" => "engine#users_get" 
     post "/users" => "engine#users_add" 
    end 
    end 

和我的主控制器是 -

class Api::V1::MainController < ApplicationController 

    http_basic_authenticate_with name: ENV["API_USERNAME"], password: ENV["API_PASSWORD"] 

    API_CMDS_LIST = { 
    "Engine" => [:users_add, :users_update], 
    } 

    include Api::V1::ErrorMessage 
    skip_before_filter :verify_authenticity_token 
    protect_from_forgery with: :null_session 

    def resulting_json(resp) 
    if resp[:result] == "error" && !resp[:code] 
     resp[:code] = Api::V1::ErrorMessage::CODES[resp[:message]] || Api::V1::ErrorMessage::DEFAULT_CODE 
    end 

    render json: resp 
    end 

    def authenticate 
    #authenticate_or_request_with_http_basic do |user, password| 

     #File.write('test.txt', "USER: #{user}. PASS: #{password}") 
     #@user && password == @user.secret_token #&& @user.belongs_to_active_brand? 
     true 
    #end 
    end 

    def validate_request 
    action = params[:action] 
    klass = API_CMDS_LIST.select{ |klass, methods| methods.include?(action.to_sym) }.keys[0] 

    @req = "Api::V1::#{klass}".constantize.new(send("# {action}_params").merge({user: @user}), request) 

    if !@req.valid? 
     err_msg = @req.errors.full_messages.first 
     code = Api::V1::ErrorMessage::CODES[err_msg] || Api::V1::ErrorMessage::DEFAULT_CODE 
     render json: { result: "error", msg: err_msg, code: code } and return 
    end 
    end 

end 

和發動機控制器代碼 -

class Api::V1::EngineController < Api::V1::MainController 
    include Api::V1::ErrorMessage 
    before_filter :validate_request 

    API_CMDS_LIST["Engine"].each do |method| 

    define_method(method) do 
     response = @req.send(method) 
     resulting_json(response) 
    end 
    end 

    def users_add_params 
    params.permit(:first_name, :last_name) 
    end 
end 

，但是當我嘗試打端點「/用戶」使用參數{FIRST_NAME：「SATY am「，last_name：」agrawal「}它給我這個錯誤---

Api :: V1 :: EngineController＃users_add處理爲JSON 參數：{」first_name「=>」satyam「，」last_name「 => 「阿格拉瓦爾」} 完成500內部服務器錯誤在1ms內（ActiveRecord的：0.0ms）

請幫我整理出來

Answer 1

有了你給它看起來像它的失敗上main_controller.rb日誌

http_basic_authenticate_with name: ENV["API_USERNAME"], password: ENV["API_PASSWORD"] 

調試的一種方法是進入您的rails控制檯並檢查是否設置了您的環境變量。

rails console 

ENV['API_USERNAME'] 
    => 'api_username' 

ENV['API_PASSWORD'] 
    => 'hash1234090909'
