我正在尝试编写自己的资金聚合器,因为市场上大多数可用工具尚未覆盖所有金融网站。我在raspberrypi上使用python 2.7.9。
由于请求库,我设法连接到我的两个帐户(一个放贷网站和一个我的养老金)。 我想要汇总的第三个网站给我带来了2个星期以来的困难,它的名字是https://www.amundi-ee.com。
我发现该网站实际上是在使用JavaScript,经过多次研究后我最终使用了dryscrape(我不能使用selenium因为不再支持Arm)。
问题:
运行此代码时:
import dryscrape
url='https://www.amundi-ee.com'
extensionInit='/psf/#login'
extensionConnect='/psf/authenticate'
extensionResult='/psf/#'
urlInit = url + extensionInit
urlConnect = url + extensionConnect
urlResult = url + extensionResult
s = dryscrape.Session()
s.visit(urlInit)
print s.body()
login = s.at_xpath('//*[@id="identifiant"]')
login.set("XXXXXXXX")
pwd = s.at_xpath('//*[@name="password"]')
pwd.set("YYYYYYY")
# Push the button
login.form().submit()
s.visit(urlConnect)
print s.body()
s.visit(urlResult)
代码访问urlConnect第21行时出现问题,正文打印行22返回以下内容:
{"code":405,"message":"No route found for \u0022GET \/authenticate\u0022: Method Not Allowed (Allow: POST)","errors":[]}
问题
为什么我有这样的错误消息?如何正确登录网站以检索我要查找的数据?
PS:我的代码灵感来自这个问题 Python dryscrape scrape page with cookies
答案 0 :(得分:0)
好的,经过一个多月的努力解决这个问题,我很高兴地说我终于得到了我想要的东西
问题是什么?
基本上有两件大事(可能更多,但我可能已经忘记了):
login.form().submit()
通过点击验证按钮足够好来搞乱所需数据页面的访问这是最终的代码,如果你发现一个糟糕的用法,请不要犹豫,因为我是一个python新手和一个零星的编码器。
