使用socket模拟数据流计算

Posted 2020-09-19 葫芦杯

场景描述：

客户端读取一个文件的每一行

与服务端建立scoket链接

服务端接收客户端发送的数据

服务端将文件写到本地

 

客户端代码：

import socket
import time
obj = socket.socket()

obj.connect(("192.168.169.133",8080))

ret_bytes = obj.recv(1024)
ret_str = str(ret_bytes,encoding="utf-8")
#print(ret_str)
filename ="d:/part-r-00000.txt"

while True: 
    inp =""
    if inp == "q":
        obj.sendall(bytes(inp,encoding="utf-8"))
        break
    else:
        for line in open(filename): 
            time.sleep(1/20)
            inp = line
            obj.sendall(bytes(inp, encoding="utf-8"))
            ret_bytes = obj.recv(1024)
            ret_str = str(ret_bytes,encoding="utf-8")
            print(ret_str)

 

服务端代码：

import  socketserver
#服务端

class Myserver(socketserver.BaseRequestHandler):

    def handle(self):
        f=open(‘f.txt‘,‘a‘)

        conn = self.request
        conn.sendall(bytes("你好，我是机器人",encoding="utf-8"))
        while True:
            ret_bytes = conn.recv(1024)
            ret_str = str(ret_bytes,encoding="utf-8")
            f.write(ret_str) 
            f.write(‘\n‘) 
            if ret_str == "q":
                break
            conn.sendall(bytes(ret_str+"你好我好大家好",encoding="utf-8"))
        
        f.close()

if __name__ == "__main__":
    server = socketserver.ThreadingTCPServer(("192.168.169.133",8080),Myserver)
    server.serve_forever()
