Ruby on Rails 学习笔记 一

最近在用rails设计一个网站的API，觉得需要注意的两个地方：

1. 注意在ActionController里设置:

protect_from_forgery :except => :your_action
           

   允许公开的非Get方式的请求 

2. 注意在config/routes.rb里设置好相关的路由，尤其是Post或者Get的方式：

map.connect 'controller/action', :conditions => {:method => :post}, :controller => "controller", :action => "action"
map.connect 'controller/action', :conditions => {:method => :get}, :controller => "controller", :action => "action"
           

Ruby发送http request的小结：

1. Ruby 以Get方式发送http request:

def get_http(host, path, port, query)
    return Net::HTTP.get(host, "#{path}?".concat(query.collect { |k,v| "#{k}=#{CGI::escape(v.to_s)}" }.reverse.join('&')), port) if not query.nil?
    return Net::HTTP.get(host, path, port)
end

def get(uri)
    url = URI.parse(uri)
    host = url.host
    path = url.path
    port = url.port
    query = url.query
    get_http(host, path, port, query)
end
           

get("http://localhost:3000/controller/action?sign=a98689zhxnxyi")
           

2. Ruby 以Post方式发送http request:

def post(uri, params)
    url = URI.parse(uri)
    Net::HTTP.start(url.host, url.port) do |http|
        res = Net::HTTP::post_form(url, params)
        puts res.body
    end
end
           

post("http://localhost:3000/controller/action", { 'sign' => 'zzbxxwz89y6n'})
