[英]Hello I'm new to Python and scripting. Each time I try to run it in the Terminal I get a Error(Please HELP) what am I doing wrong?
[英]Python Socket Scripting. What am i doing wrong?
我的套接字程序掛在clientsocket(地址)= serversocket.accept()上,不會吐出任何錯誤或其他信息。
我按照https://docs.python.org/3/howto/sockets.html上的說明進行操作
我一直在試圖弄清楚一個小時,但無濟於事。 我正在使用python3 btw。 我究竟做錯了什么? 編輯:我的想法都搞砸了,因為我粘貼錯了,但除此之外,我的代碼是我在文件中擁有的。
#import socket module
import socket
#creates an inet streaming socket.
serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print('socket created')
#binds socket to a public host, and a well known port
serversocket.bind(('127.0.0.1', 1024))
#print(socket.gethostname())# on desktop prints 'myname-PC')
#become a server socket
serversocket.listen(5) # listens for up to 5 requests
while True:
#accept connections from outside
#print('In while true loop') This works, but we never get to the next print statement. Why the hell is it catching at line 20?
(clientsocket, address) = serversocket.accept()
#clientsocket = serversocket.accept()
print('Ready to serve')
#now we do something with client socket...
try:
message = clientsocket.recv(1024)
filename = message.split()[1]
f = open(filename[1:])
outputdata = f.read()
#send an http header line
clientsocket.send('HTTP/1.1 200 OK\nContent-Type: text/html\n\n')
for i in range(0, len(outputdata)):
clientsocket.send(outputdata[i])
clientsocket.close()
except IOERROR:
clientsocket.send('HTTP/1.1 404 File not found!')
clientsocket.close()
如果您尚未編寫客戶端腳本/程序來連接到套接字並發送數據,則由於沒有任何內容可以接受,因此它也將掛在serversocket.accept()上。 但是假設你有...
while True:
#accept connections from outside
#print('In while true loop') This works, but we never get to the next print statement. Why the hell is it catching at line 20?
(clientsocket, address) = serversocket.accept()
#clientsocket = serversocket.accept()
它掛起是因為循環永遠不會因為True始終為True而退出。 在提供的示例中,一旦連接被接受,他們就假裝服務器已線程化,其想法是創建一個單獨的線程以開始讀取和處理接收到的數據,從而允許套接字繼續偵聽更多的連接。
while True:
# accept connections from outside
(clientsocket, address) = serversocket.accept()
# now do something with the clientsocket
# in this case, we'll pretend this is a threaded server
ct = client_thread(clientsocket)
ct.run()
