HTTParty 使 Sinatra 崩溃

Question

我有一个小型模块化 Sinatra 应用程序，我正在构建它作为单独 REST API 的前端。一切都很顺利，直到我添加了 HTTParty（向我的 API 发出请求），现在不会加载任何页面。

API 服务器在 localhost 端口 9393 上运行，但即使我关闭该服务器，错误仍然存​​在。 （当我注释掉路由中的一个 HTTParty 请求时。

这是我的 app.rb 文件：

ENV["RACK_ENV"] ||= "development"

require 'bundler' require 'sinatra/base' require 'sinatra/contrib/all' require 'json' require 'sinatra/strong-params' require 'haml' require 'sinatra/partial' require 'sass'
# require 'httparty'

require 'pry'


Bundler.setup Bundler.require(:default, ENV["RACK_ENV"].to_sym)

# DATABASE CONFIG
# dbconfig = YAML.load(File.read('./config/database.yml'))
# ActiveRecord::Base.establish_connection dbconfig["#{settings.environment}"]

# Base URL for API calls API_BASE = 'http://localhost:9393'

class PantryApp < Sinatra::Base   include HTTParty   register Sinatra::Partial

  set :root, File.dirname(__FILE__)   enable :sessions

  # set folder for templates to ../views, but make the path absolute   set :views, File.expand_path('../app/views', __FILE__)

  # don't enable logging when running tests   configure :production, :development do
    enable :logging   end

  # will be used to display 404 error pages   not_found do
    erb :not_found   end

  get '/' do
    haml :login   end

  get '/login' do
    haml :login   end

  post '/login' do
    # api_token = HTTParty.post(API_BASE + '/token', query: {email: params['email'], password: params['password']})
    binding.pry
    haml :user_pantry   end

  # REQUIRE ALL APP FILES   Dir["./app/**/*.rb"].each { |f| require f }

end

当我尝试转到 /login 时，我得到：

Boot Error

Something went wrong while loading config.ru

而config.ru 很简单：

require File.dirname(__FILE__) + '/app.rb'

map('/users') { run UsersController }
map('/') { run PantryApp }

在我看来，我在 app.rb 中的第一条路线的“get”导致了 httparty 而不是 Sinatra，但我不知道为什么或如何解决它。

Answer 1

我回答了我自己的问题，但我想把它留在这里，以防它对其他人有用。

在这种情况下，我不需要在类中使用include HTTParty，而是在顶部使用它。我认为使用include 是混淆get 请求的原因。
