我将如何使用错误的输出修复此脚本？

Question

它以多种方式搞砸了

代码如下：

import threading
import sys
import time
import os
import subprocess
import requests
import threading

ip = sys.argv[1:]

website_loaded = False

def verify():
    while website_loaded == False:
        sys.stdout.write("Verifying IP    \r")
        time.sleep(0.5)
        sys.stdout.write("Verifying IP.   \r")
        time.sleep(0.5)
        sys.stdout.write("Verifying IP..  \r")
        time.sleep(0.5)
        sys.stdout.write("Verifying IP... \r")
        time.sleep(0.5)
        continue

verify_thread = threading.Thread(target = verify, args = ())
verify_thread.start()

ping = os.system("ping %s >nul" % str(ip))
ipVerification = subprocess.getoutput(str(ping))

website_loaded = True
if ipVerification == "Ping request could not find host %s. Please check the name and try again." % ip:
    print("Invalid IP. Please try again")
    print("Press any key to exit")
    os.system("pause >nul")
    exit()
elif ipVerification.find('PING: transmit failed. General failure.') != -1:
    print("Invalid IP. Please try again")
    print("Press any key to exit")
    os.system("pause >nul")
    exit()
website_loaded = False

def loading():
    while website_loaded == False:
        sys.stdout.write("Loading    \r")
        time.sleep(0.5)
        sys.stdout.write("Loading.   \r")
        time.sleep(0.5)
        sys.stdout.write("Loading..  \r")
        time.sleep(0.5)
        sys.stdout.write("Loading... \r")
        time.sleep(0.5)
        continue

loading_thread = threading.Thread(target = loading, args = ())
loading_thread.start()

info = requests.get("http://ip-api.com/json/%s" % ip).json()

website_loaded = True

print(info)

当我在cmd中输入“ipinfo.py 55”时，输出是“{'message': 'invalid query', 'query': '[]', 'status': 'fail'} 正在加载... P...”，我不知道为什么。我希望它说 IP 无效，但由于某种原因，它正在做这个奇怪的事情

要获取单个 IP，请执行以下操作：

ip = sys.argv[1]

如果您想要正确的命令行处理，请查看argparse。

如果您使用的是subprocess，则无需执行os.system。而不是：

ping = os.system("ping %s >nul" % str(ip))
ipVerification = subprocess.getoutput(str(ping))

你可以这样做：

ipVerification = subprocess.getoutput(f"ping {ip}")

当ip = 55 这个ipVerification 的值是：

connect: Invalid argument

这将允许您在调用ip-api.com API 之前捕获它。或者，您可以忽略 ping，让来自 ip-api.com 的响应中的 message 确定 IP 地址是否有效。

if response.get("message") == "invalid query":
    print(f"The IP address is invalid: {ip}".
else:
    print(response.get("isp"))
