Question

我无法从span标记中获取值，如下所示：

var error = driver.findElement(webdriver.By.id('error-container-text')).getAttribute('innerHTML');

但这显示出类似的内容 -

ManagedPromise {
  flow_: 
   ControlFlow {
     propagateUnhandledRejections_: true,
     activeQueue_: 
      TaskQueue {
        name_: 'TaskQueue::216',
        flow_: [Circular],
        tasks_: [Object],
        interrupts_: null,
        pending_: null,
        subQ_: null,
        state_: 'new',
        unhandledRejections_: Set {} },
     taskQueues_: Set { [Object] },
     shutdownTask_: null,
     hold_: 
      Timeout {
        _called: false,
        _idleTimeout: 2147483647,
        _idlePrev: [Object],
        _idleNext: [Object],
        _idleStart: 22977,
        _onTimeout: [Function],
        _timerArgs: undefined,
        _repeat: 2147483647 } },
  stack_:

尝试使用以下内容：

import requests
import urllib.request
from lxml import html

def PictureScraping():
    url = "https://www.yify-torrent.org/search/1080p/"
    response = requests.get(url)
    tree = html.fromstring(response.text)
    titles = tree.xpath('//div[@class="movie-image"]')
    for title in titles:
        Pics = "https:" + title.xpath('.//img/@src')[0]
        urllib.request.urlretrieve(Pics, Pics.split('/')[-1])
PictureScraping()
