requests-html的js执行功能简单使用

Posted 2020-11-09 一起来学python

#运行js
session=HTMLSession()
r=session.get("https://www.facebook.com/login.php?login_attempt=1")
#开始调用pyppeteer
dom=r.html
#page1=dom.render()#相当于await page.evaluate

#page=dom.render(script=script)#相当于await page.evaluate

# print(dir(dom)) #获取dom对象所有的属性和方法
# print(dom.__dict__) #获取dom对象所有的属性和值,字典形式
# print(dom.links) #获取所有相对连接
# print(dom.absolute_links) #获取所有连接的完整路径
#dom.session就相当于requests模块的response了
#print(dom.render(script=geturl))
print(dom.render(script=loginjs))
time.sleep(5)
print(dom.session)
