1、low版本（使用者端）：
from socket import *ip_port = ("
127.0.0.1
",8080)
back_log = 5buffer_size = 1024tcp_client =socket(af_inet,sock_stream) #ipv4 internet協議，sock_stream位元組流，對應tcp，sock_dgram資料報文，對應udp
tcp_client.connect(ip_port)
while 1:
cmd = input("
>>>>>>>>:
").strip()
ifnot
cmd:
continue
if cmd == "
quit":
break
tcp_client.send(cmd.encode(
"utf-8"))
#解決粘包
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 cmd_res =tcp_client.recv(buffer_size)
recv_msg = recv_msg +cmd_res
recv_size =len(recv_msg)
print("
命令的執行結果是
",recv_msg.decode("
gbk"
))tcp_client.close()
服務端：
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("新的客戶端連線是%s,位址是%s"%(conn,adr))
while 1:
try:
cmd = conn.recv(buffer_size)
if not cmd:
break
print("收到客戶端的命令",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:#為空
if err:#有值
cmd = err
else:
cmd_res = res.stdout.read()#bite
if not cmd_res:
cmd_res = "執行成功".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：（提公升效能）
使用者端：
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"))
#解決粘包
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("命令的執行結果是",recv_msg.decode("gbk"))
tcp_client.close()
服務端：
from socket import *import
subprocess
import
struct
ip_port = ("
127.0.0.1
",8080)
back_log = 5buffer_size = 1024tcp_server =socket(af_inet,sock_stream)
tcp_server.bind(ip_port)
tcp_server.listen(back_log)
while 1:
conn,adr =tcp_server.accept()
print("
新的客戶端連線是%s,位址是%s
"%(conn,adr))
while 1:
try:
cmd =conn.recv(buffer_size)
ifnot
cmd:
break
print("
收到客戶端的命令
",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:#為空
if err:#
有值 cmd =err
else
: cmd_res = res.stdout.read()#
bite
ifnot
cmd_res:
cmd_res = "
執行成功
".encode("
gbk"
) length =len(cmd_res)
data_length = struct.pack("i"
,length)
conn.send(data_length)
conn.send(cmd_res)
except
exception as e:
(e)
break
conn.close()
