我正在尝试检查包含将返回响应状态代码 200 的 url 的文件。我正在使用 python 3.7.1 下面是我用过的代码
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)
以上代码触发错误

用于 txt 的文件的 URL
当直接使用 requests.get("https://www.instagram.com") 测试时，上述 url 给出了所需的输出。
最佳答案
您应该从字符串中删除结尾的换行符:
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)
关于python - requests.exceptions.ConnectionError : ('Connection aborted.' , gaierror(8, 'nodename nor servname provided, or not known' ))，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57690498/
