红宝石插座 - 运行在socker上的方法

Question

我是Ruby插座中的新手。我在服务器项目，我坐了起来插座的服务器如下：

require 'socket'    
server = TCPServer.open(2000)  
loop {       
    Thread.start(server.accept) do |client| 
    client.puts(Time.now.ctime) 
    client.puts "Closing the connection. Bye!" 
    client.close     
end 

我想从客户端运行我的方法之一，在我的项目：

require 'socket'  

hostname = 'localhost' 
port = 2000 

s = TCPSocket.open(hostname, port) 

while line = s.gets  
    puts line.chop  
    puts "hey" 

    # call helloWorldMethod() 
end 

s.close     

Answer 1

require 'socket'    
server = TCPServer.open(2000)  
loop do       
    Thread.start(server.accept) do |client| 
    client.puts(Time.now.ctime) 
    client.puts "Closing the connection. Bye!" 
    client.close     
    end 
end 

我相信您的解决方案是在​​

，我发现这个文档中关于ruby socket programming

微型网页浏览器

我们可以使用套接字库来实现任何Internet协议。这里，例如，是抓取网页

取决于你的路由你可能要调整URL的内容的代码，它chould是www.yourwebsite.com/users

require 'socket' 

host = 'www.tutorialspoint.com'  # The web server 
port = 80       # Default HTTP port 
path = "/index.htm"     # The file we want 

这是HTTP请求我们发送获取文件

，您可以在HTTP post或put要求

改变你的要求

request = "GET #{path} HTTP/1.0\r\n\r\n" 

socket = TCPSocket.open(host,port) # Connect to server 
socket.print(request)    # Send request 
response = socket.read    # Read complete response 
# Split response at first blank line into headers and body 
headers,body = response.split("\r\n\r\n", 2) 
print body       # And display it 

要实现类似的Web客户端，您可以使用像Net :: HTTP这样的预建库来处理HTTP。以下是代码，代码相当于以前的代码 -

require 'net/http'     # The library we need 
host = 'www.tutorialspoint.com'  # The web server 
path = '/index.htm'     # The file we want 

http = Net::HTTP.new(host)   # Create a connection 
headers, body = http.get(path)  # Request the file 
if headers.code == "200"   # Check the status code 
    print body       
else         
    puts "#{headers.code} #{headers.message}" 
end
