我正在尝试在已发布的Power BI报表中抓取刷新日期对象，以便可以看到上次刷新服务器上的报表的时间。为了做到这一点，我一直在尝试将Beautiful Soup和Selenium与Python结合使用。但是，实际上我没有运气来开始输出任何html代码。
我是否需要使用特定的网址或在URL中添加一些内容才能使其刮取此报告的网站？
这是我一直在使用的代码：
## install google chrome
! wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
! sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list'
! apt-get -y update
! apt-get install -y google-chrome-stable
#
## install chromedriver
! apt-get install -yqq unzip
! echo "y" | wget -O /tmp/chromedriver.zip http://chromedriver.storage.googleapis.com/`curl -sS chromedriver.storage.googleapis.com/LATEST_RELEASE`/chromedriver_linux64.zip
! echo "y" | unzip /tmp/chromedriver.zip chromedriver -d /usr/local/bin/
#
## install xvfb
! apt-get install -yqq xvfb
#
## set display port and dbus env to avoid hanging - in Environment file
! ENV DISPLAY=:99
! ENV DBUS_SESSION_BUS_ADDRESS=/dev/null
#
## install selenium
! pip install selenium==3.8.1

##Install beautifulsoup
! pip install bs4
