A simple example of sending a request based on an HTTP protocol in a Ruby program _ruby topic

1. Establish an HTTP connection (send request parameters by Get method)

Require "Open-uri"  
#如果有GET请求参数直接写在URI地址中  
uri = ' Http://uri '  
html_response = nil  
open (URI) do |http|  
Html_response = Http.read  
end  
puts Html_response  
require "Open-uri" 
#如果有GET请求参数直接写在URI地址中 
URI = ' Http://uri ' 
html_response = nil 
open (URI) do |http| 
Html_response = Http.read 
end 
puts Html_response 

2. Send request Parameters via post

params = {}  
params[' name ' = ' Tom '  
uri = uri.parse (' Http://uri ')  
res = Net::http.post_form
(URI, params)  
#返回的cookie  
puts res.header[' Set-cookie ']  
#返回的html body  
puts res.body  
= {} 
params["Name" = ' Tom ' 
uri = Uri.parse ("Http://uri") 
res = Net::http.post_form
(URI, params)  
#返回的cookie 
puts res.header[' Set-cookie '] 
#返回的html body 
puts Res.body 

3.HTTPS Request

# 
Description: 
#  send courier data to Datasystem, use HTTPS 
# input: # data  -assembled Expess's 
output:  # Datasystem return status Information 
# 
def self.senddatassl (url,data) 
 url = url + data 
 $logger. info (URL) 
 Begin 
  URI = Uri.parse (uri.escape (URL)) 
  http = net::http.new (uri.host, uri.port) 
  Http.use_ssl = True 
   
  if ($logger!= nil) 
   $logger. Info ("link address parameter: #{uri.escape (URL)}, FileName: #{__file__}, #{__line__} line") 
   $ Logger.info ("Incoming data parameter: #{data.to_json}, FileName: #{__file__}, #{__line__}") End 
  request = Net::http::get.new (Uri.request_uri) 
   
  Response = http.request (Request) 
 rescue =>exception 
  $logger. Error ("Delivery URL address is #{url}, error!#{exception.to_ s}, FileName: #{__file__}, #{__line__} line ") Return 
  Nil end 
 return 
 Response.body
