python3 登录后 获取 cookie 继续进行下一步操作

使用的是 urllib cookiejar

这里 以 jira 为例

def getAuthorizationCookie():
    url = 'https://jira.amer.XXX.com/login.jsp'

    headers = {
               'Content-Type': 'application/x-www-form-urlencoded',
               'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Safari/537.36',
               'Connection': 'keep-alive',
               'Host': 'jira.amer.XXXX.com',
               'Referer': 'https://jira.amer.XXXX.com/login.jsp'
               }
    params = {
        'os_username': '[email protected]',
        'os_password': 'your_password',
        'os_destination': '/issues/?jql=project%20%3D%20SCME%20AND%20issuetype%20in%20subTaskIssueTypes()',
        'user_role': '',
        'atl_token': '',
        'login': 'Log In'
    }
    data = urllib.parse.urlencode(params).encode('utf-8')
    request = urllib.request.Request(url = url,data = data,headers = headers,method = 'POST')
    cjar = cookiejar.CookieJar()
    # 使用HTTPCookieProcessor创建cookie处理器，并以其为参数构建opener对象
    cookie = urllib.request.HTTPCookieProcessor(cjar)
    opener = urllib.request.build_opener(cookie)
    # 将opener安装为全局
    urllib.request.install_opener(opener)

    response = urllib.request.urlopen(request)
    return cjar

这里获取到 cookie 类 在下一步的操作中 把cookie 给下一次请求 携带访问

def downLoadFIle():
    cookie = getAuthorizationCookie()
    handler = urllib.request.HTTPCookieProcessor(cookie)
    opener = urllib.request.build_opener(handler)

    get_url = 'https://jira.amer.thermo.com/sr/jira.issueviews:searchrequest-csv-current-fields/temp/SearchRequest.csv?jqlQuery=project+%3D+SCME+AND+issuetype+in+subTaskIssueTypes%28%29'
    urllib.request.install_opener(opener)
    get_request = urllib.request.Request(get_url)
    get_response = urllib.request.urlopen(get_request)
    data = get_response.read()
    with open('jira11.csv', 'wb') as f:
        f.write(data)

这里的方法就是进行了一下 下载操作
