但是执行>>> r = requests.get("http://www.126.com")是正常的

print(r.status_code)

200

r.text

最好添加个请求头headers
SSL设置为 verify=False

headers = {'User-Agent':
'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.104 Safari/537.36'
}
requests.get("http://www.baidu.com",headers=headers, verify=False)
