是否是使用了代理后
ssl._create_default_https_context = ssl._create_unverified_context
无效

获取代理ip

def get_proxy():
return requests.get("http://127.0.0.1:5010/get/").content

获得页面数据

def do_spider(page_no=1, encoding="gbk", parse_url="null"):
ssl._create_default_https_context = ssl._create_unverified_context
proxy = request.ProxyHandler({
"sock5": get_proxy()
})

opener = request.build_opener(proxy)
opener.addheaders = [('User-agent', 'Mozilla/5.0')]
request.install_opener(opener)
# 对于二级页面进行爬取
if parse_url == "null":
    html_bytes = request.urlopen(url.format(page_no)).read()
else:
    html_bytes = request.urlopen(parse_url).read()
html_code = str(html_bytes, encoding)
return html_code

    异常

循环6次左右后就会爆上面这个异常

python 仅仅是引入 requests即报错
