测试python是否可以联网

使用如下代码即可 

import requests

# 设置代理服务器地址

proxy_address = "http://127.0.0.1:10809"

# 创建代理字典

proxies = {

    "http": proxy_address,

    "https": proxy_address

}

def check_internet_connection():

    baidu_result = False

    google_result = False

    try:

        # Check connection to baidu.com

        response = requests.get("http://www.baidu.com", proxies=proxies)

        if response.status_code == 200:

            baidu_result = True

    except requests.exceptions.RequestException:

        baidu_result = False

    try:

        # Check connection to google.com

        response = requests.get("http://www.google.com", proxies=proxies)

        if response.status_code == 200:

            google_result = True

    except requests.exceptions.RequestException:

        google_result = False

    if baidu_result:

        print("网络可以上网")

    else:

        print("无法连接到网络")

    if google_result:

        print("已连接谷歌")

    else:

        print("无法科学上网")

# 循环调用函数

for _ in range(5):

    check_internet_connection()
