urllib的SSL错误

问题描述

尝试使用BeautifulSoup4抓取网站时出现SSLError ，但我使用urllib只是打开了链接。 通过在我要从 JSoup的网站生成证书，我使其与JSoup （Java的刮板程序）一起在Java中工作。 是否可以在Python中使用该证书？ 生成的文件称为jssecacerts，但重命名为cacerts。

这是我正在使用的代码：

def open(url, postdata=None):
    if postdata is not None:
        postdata = urlencode(postdata)
        postdata = postdata.encode('utf-8')
    return browser.open(url, postdata).read()

def login(i):
    cj = http.cookiejar.CookieJar()
    global browser
    browser = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cj))

    POST = {'timezoneOffset': TIMEZONEOFFSET,
            'userid': USERID,
            'pwd': PWD,
            }

    open(LOGIN_URL, POST)

错误：
