我有一个名为app.rb的文件,当我在本地机器上运行服务器时运行服务器。我想将app.rb部署到Heroku,以便服务器在Heroku上运行。我认为我需要在routes.rb中指向它。我该怎么做呢?rails + heroku:指向routes.rb文件的根目录到app.rb文件
这是config.ru:
require_relative 'config/environment'
require '/.app.rb'
run Rails.application
run Sinatra::Application
这是app.rb web服务器代码,代码路径从引导件(https://guides.codepath.com/android/Google-Cloud-Messaging#step-3-setup-web-server):
require 'sinatra'
require 'rest-client'
require 'sequel'
# Create a SQLite3 database
DB = Sequel.connect('sqlite://gcm-test.db')
# Create a Device table if it doesn't exist
DB.create_table? :Device do
primary_key :reg_id
String :user_id
String :reg_token
String :os, :default => 'android'
end
Device = DB[:Device] # create the dataset
# Registration endpoint mapping reg_token to user_id
# POST /register?reg_token=abc&user_id=123
post '/register' do
if Device.filter(:reg_token => params[:reg_token]).count == 0
device = Device.insert(:reg_token => params[:reg_token], :user_id => params[:user_id], :os => 'android')
end
end
# Ennpoint for sending a message to a user
# POST /send?user_id=123&title=hello&body=message
post '/send' do
# Find devices with the corresponding reg_tokens
reg_tokens = Device.filter(:user_id => params[:user_id]).map(:reg_token).to_a
if reg_tokens.count != 0
send_gcm_message(params[:title], params[:body], reg_tokens)
end
end
# Sending logic
# send_gcm_message(["abc", "cdf"])
def send_gcm_message(title, body, reg_tokens)
# Construct JSON payload
post_args = {
# :to field can also be used if there is only 1 reg token to send
:registration_ids => reg_tokens,
:data => {
:title => title,
:body => body,
:anything => "foobar"
}
}
# Send the request with JSON args and headers
RestClient.post 'https://gcm-http.googleapis.com/gcm/send', post_args.to_json,
:Authorization => 'key=' + AUTHORIZE_KEY, :content_type => :json, :accept => :json
end
这是procfile:
web: bundle exec puma -C config/puma.rb
当我按照Ruby on Heroku入门的例子,我可以看到示例webpag即不过,如果我编辑与“运行西纳特拉::应用”的config.ru文件,并将其部署到Heroku的,它是不是能再显示网页例子,只是说:“未找到”
你能提供更多的细节吗? 'app.rb'是否定义了应用程序服务器的Rack应用程序?你可以粘贴你的'config.ru'(如果你有)? –
require_relative'config/environment' require'/.app.rb' 运行Rails.application 运行Sinatra ::应用程序 – mjpablo23
好的,谢谢,我已经把app.rb和config.ru代码放进去了。我不确定Rack应用是什么。该代码是用于接收和发送推送通知的服务器。 – mjpablo23
