Ruby套接字 - 在Socker上运行方法

Question

我是Ruby套接字的新手。我在服务器中有项目，并且我坐在服务器中的插座如下：

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

我想从客户端从项目中运行我的一种方法：

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在TCPSERVER类中

我找到了有关Ruby插座编程的文档

微小的Web浏览器

我们可以使用套接字库来实现任何Internet协议。例如，这里是获取网页内容

的代码

根据您的路由，您可能需要适应URL，它可能是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 

这是我们发送的HTTP请求以获取文件

您可以在HTTP post或put请求

中更改您的请求

request = "GET #{path} HTTP/1.0rnrn"
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("rnrn", 2) 
print body                          # And display it

要实现类似的Web客户端，您可以使用诸如NET :: HTTP之类的预构建库与HTTP合作。这是执行以前代码的代码 -

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
