我想在Heroku上部署我的应用程序。我的应用程序抓取公寓网站的数据。对于一个URL，我有多个选择器。应用程序使用APSceduler运行。日志显示以下错误：

已解码：
about：netror？e=netTimeout&u=&d=位于x的服务器响应时间过长。
如果我转到链接，我就可以访问它。我已经禁用了JavaScript和图像，以便更快地加载链接。
我不确定这里有什么问题。

结果发现，目标网站屏蔽了Heroku。解决方法是使用代理

我认为您希望等到您正在寻找的元素等待：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.common.exceptions import TimeoutException

try:
   my_element = WebDriverWait(browser, delay).until(EC.presence_of_element_located((By.ID, 'ID_of_element')))
   print "Page is ready"
except TimeoutException:
   print "Loading took to much time"

遇到同样的问题，也许其他人也可以防止同样的错误。如果网站使用http，但你输入https，它也会有这个确切的错误
示例：

正确的网站：http://some-website.com

driver.get('http://some-website.com')
错误
