我正在工作和一個簡單的套接字程序,並需要測試客戶端發送到服務器的值。我在一個地步,我可以打印服務器上的客戶端輸入,但任何數據發送,則返回true,當我用「startswith」測試在python3 startswith似乎總是返回True
代碼:
'''
Simple socket server using threads
'''
import socket
import sys
from _thread import *
HOST = ''
PORT = 127 # Arbitrary non-privileged port
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print("Socket created")
#Bind socket to local host and port
try:
s.bind((HOST, PORT))
except socket.error as msg:
print("Bind failed. Error Code : " + str(msg[0]) + " Message " + msg[1])
sys.exit()
print("Socket bind complete")
#Start listening on socket
s.listen(10)
print("Socket now listening")
#Function for handling connections. This will be used to create threads
def clientthread(conn):
#Sending message to connected client
#conn.send("Welcome to the server. Type something and hit enter") #send only takes string
#infinite loop so that function do not terminate and thread do not end.
commandz = ""
while True:
#Receiving from client
data = conn.recv(1024)
commandz += data.decode()
#reply = "OK..." + commandz
print(commandz)
if commandz.startswith('F'):
print("Forwardmove")
else:
print("Not forward")
if not data:
break
#conn.sendall("heard you")
#came out of loop
conn.close()
#now keep talking with the client
while 1:
#wait to accept a connection - blocking call
conn, addr = s.accept()
print("Connected with " + addr[0] + ":" + str(addr[1]))
#start new thread takes 1st argument as a function name to be run, second is the tuple of arguments to the function.
start_new_thread(clientthread ,(conn,))
s.close()
不要使用'進口*'第一個數據並打印。另外,你確定你想要低層'_thread'而不是其中一個高層模塊嗎? – ThiefMaster
'127'不是非特權端口。你需要一個大於1024的。 – ThiefMaster
你能詳細說明導入*有什麼問題嗎?對此語言不熟悉,歡迎所有反饋。 – WillMc
