运用selenium进行爬虫时，获取的网页中的body内的内容被字符“正在载入中代替”，请问如何解决。这导致了我无法对网页进行元素提取。print("开始执行")op = webdriver.Chrome(r'C:\Program Files\Google\Chrome\Application\chromedriver.exe')
op.get('http://www.sci-hub.tw.cn/')
e01=op.find_element_by_tag_name('input')
e01=op.find_element_by_tag_name('input')
e01.send_keys('此处为账号')
e02=op.find_elements_by_tag_name('input')
e02.send_keys('此处为密码')
e03=op.find_element_by_tag_name('button')
e03.click()
time.sleep(5)
op.refresh()
html=op.page_source
print(html)
下面务必注意html文件中的“正在载入”下为输出的html源代码:<html lang="en"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8">
