Question

我在发送数据包时遇到麻烦，我将较旧的代码从python的较旧版本导出到了python3。我收到TypeError：需要输入整数（错误类型为str），并且我不知道如何解决它

import socket
import random
import time

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

bytes = random._urandom(1024)

ip = int(input('Target ip:'))
port = int(input('port:'))
duration = int(input('number of seconds to send packets: '))
timeout = time.time() + float(duration)
sent = 0
while True:
    if time.time() > timeout:
        break
    else:
        pass
    sock.sendto(bytes,(ip,port))
    sent = sent + 1
    print ("sent %s packets to %s through port %s")%(sent, ip, port)

我是这个论坛的新手，所以提前对不起。

这里有我的完整回溯

    Target ip:157.240.22.35:
port:8080
number of seconds to send packets: 2

TypeError: an integer is required (got type str)

Answer 1

limit = n，$query = "SELECT `firstName`, `lastName`, `nickName`, `cellNumber` , `workNumber` , `homeNumber` , `birthday` , `memo` FROM contacts LIKE '%".$valueToSearch."%' WHERE userId = '{$_SESSION['user_id']}' ";和ip必须是我认为的整数值。因此，这应该可以解决-

port

Answer 2

根据documentation，port方法的地址元组中的socket.sendto()项必须是整数，因此应将input()的返回值转换为port转换为整数：

port = int(input('port:'))

TypeError：是否需要一个整数（类型为str）？
