requests.exceptions.ConnectionError :('Connection aborted。'，gaierror（8，'nodename或servname提供，或未知'））

Question

我正在嘗試檢查包含url的文件，該文件將返回響應狀態代碼200.我正在使用python 3.7.1下面是我使用過的代碼

import requests
import sys
url_list = sys.argv[1]
with open(url_list) as fp:
    for line in fp:
        response = requests.get(line)
        if (response.status_code == '200'):
            print ("%s is up "%line)
        print (response.status_code)

上面的代碼是觸發錯誤

用於txt的文件的URL

• https://www.google.com
• https://www.instagram.com
• https://www.facebook.com

使用requests.get("https://www.instagram.com")直接測試時，上面的網址會提供所需的輸出。

您應該從字符串中刪除尾隨換行符：

import requests
import sys

url_list = sys.argv[1]
with open(url_list, 'r') as fp:
    for line in fp:
        url = line.rstrip()
        response = requests.get(url)
        if (response.status_code == 200):
            print ("%s is up " % url)
        print (response.status_code)
