Question

以下while循环在运行IOError除外时停止

我得到了输出：

IP：192.168.1.1，PORT：80，已建立连接

IP: 192.168.1.1 ,PORT: 22 ,Connection established
IP: 192.168.1.1 ,PORT: 22 ,Connection established
IP: 192.168.1.1 ,PORT: 22 ,Connection established
IP: 192.168.1.97 ,PORT: 22 ,Cannot Connect  (stops here)

任何帮助都会很棒。我不明白为什么它会运行IOError除外，然后停止

谢谢

while True:
    f = input('Type the File Name/Path:')
    if f == '': break

    try:
        with open(f, 'r', encoding='utf-8') as f:
            for check in f:
                check = check.split("\t")
                HOSTNAME = check[0]
                IP = check[1]
                PORT = int(check[2])
                s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
                s.settimeout(TIMEOUT)
                s.connect((IP, PORT))
                f = open("output.txt", "a")
                print('IP:', IP, ',' 'PORT:', PORT, ',' "Connection established", file=f)
                time.sleep(1)
                f.close()
                s.close()

    except IOError:
            f = open("output.txt", "a")
            print('IP:', IP,',' 'PORT:', PORT,',' "Cannot Connect", file=f)
            f.close()

    except FileNotFoundError:
        print("\n")
        print('The file {} does not exist'.format(f))
        input('Press ENTER to continue...')
        print("\n")
        break

如果IO错误是由套接字调用引起的，我认为您的try/except语句必须进行一些更改。您可以尝试：

while True:
    file = input('Type the File Name/Path:')
    if file == '':
        break
    try:
        with open(file, 'r', encoding='utf-8') as f:
            for check in f:
                check = check.split("\t")
                HOSTNAME = check[0]
                IP = check[1]
                PORT = int(check[2])
                try:
                    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
                    s.settimeout(TIMEOUT)
                    s.connect((IP, PORT))
                    s.close()
                except IOError:
                    log = open("output.txt", "a")
                    print('IP:', IP,',' 'PORT:', PORT,',' "Cannot Connect", file=log)
                    log.close()
                    continue # will go back to the beginning of the while loop
                log = open("output.txt", "a")
                print('IP:', IP, ',' 'PORT:', PORT, ',' "Connection established", file=log)
                log.close()
                time.sleep(1)
    except FileNotFoundError:
        print('\nThe file {} does not exist'.format(file))
        input('Press any key to continue...\n')
        break

当我遇到IOError时，Python While循环停止
