1、low版本（用户端）：
from socket import * ip_port = ("127.0.0.1",8080) back_log = 5 buffer_size = 1024 tcp_client = socket(AF_INET,SOCK_STREAM) tcp_client.connect(ip_port) while 1: cmd = input(">>>>>>>>:").strip() if not cmd: continue if cmd == "quit": break tcp_client.send(cmd.encode("utf-8")) #解决粘包 length = tcp_client.recv(buffer_size) tcp_client.send(b"ready") length = int(length.decode("utf-8")) recv_size = 0 recv_msg = b"" while recv_size < length: cmd_res = tcp_client.recv(buffer_size) recv_msg = recv_msg + cmd_res recv_size = len(recv_msg) print("命令的执行结果是",recv_msg.decode("gbk")) tcp_client.close()
服务端：
from socket import *
import subprocess
ip_port = ("127.0.0.1",8080)
back_log = 5
buffer_size = 1024
tcp_server = socket(AF_INET,SOCK_STREAM)
tcp_server.bind(ip_port)
tcp_server.listen(back_log)
while 1:
conn,adr = tcp_server.accept()
print("新的客户端连接是%s,地址是%s"%(conn,adr))
while 1:
try:
cmd = conn.recv(buffer_size)
if not cmd:
break
print("收到客户端的命令",cmd)
res = subprocess.Popen(cmd.decode("utf-8"),shell= True,stdout=subprocess.PIPE,stderr=subprocess.PIPE,stdin=subprocess.PIPE)
err = res.stderr.read()
# if not err:#为空
if err:#有值
cmd = err
else:
cmd_res = res.stdout.read()#bite
if not cmd_res:
cmd_res = "执行成功".encode("gbk")
length = len(cmd_res)
conn.send(str(length).encode("utf-8"))
client_ready = conn.recv(buffer_size)
if client_ready == b"ready":
conn.send(cmd_res)
except Exception as e:
print(e)
break
conn.close()
2、高逼格版本：（提升性能）
用户端：
from socket import *
import struct
ip_port = ("127.0.0.1",8080)
back_log = 5
buffer_size = 1024
tcp_client = socket(AF_INET,SOCK_STREAM)
tcp_client.connect(ip_port)
while 1:
cmd = input(">>>>>>>>:").strip()
if not cmd:
continue
if cmd == "quit":
break
tcp_client.send(cmd.encode("utf-8"))
#解决粘包
length_data = tcp_client.recv(4)
length = struct.unpack("i",length_data)[0]
recv_size = 0
recv_msg = b""
while recv_size < length:
cmd_res = tcp_client.recv(buffer_size)
recv_msg = recv_msg + cmd_res
recv_size = len(recv_msg)
print("命令的执行结果是",recv_msg.decode("gbk"))
tcp_client.close()
服务端：
from socket import * import subprocess import struct ip_port = ("127.0.0.1",8080) back_log = 5 buffer_size = 1024 tcp_server = socket(AF_INET,SOCK_STREAM) tcp_server.bind(ip_port) tcp_server.listen(back_log) while 1: conn,adr = tcp_server.accept() print("新的客户端连接是%s,地址是%s"%(conn,adr)) while 1: try: cmd = conn.recv(buffer_size) if not cmd: break print("收到客户端的命令",cmd) res = subprocess.Popen(cmd.decode("utf-8"),shell= True,stdout=subprocess.PIPE,stderr=subprocess.PIPE,stdin=subprocess.PIPE) err = res.stderr.read() # if not err:#为空 if err:#有值 cmd = err else: cmd_res = res.stdout.read()#bite if not cmd_res: cmd_res = "执行成功".encode("gbk") length = len(cmd_res) data_length = struct.pack("i",length) conn.send(data_length) conn.send(cmd_res) except Exception as e: print(e) break conn.close()
