Python Selenium：PhantomJS驱动程序未加载所需的元素

Question

因此，我正在尝试自动化并从http://50.17.237.182/PIM/获取数据。如果输入类似1355025的值，它将在右窗格中加载文本。它在Firefox上可以正常工作，但在PhantomJS上，即使我放了Wait While之类的东西，它也根本没有加载所需的元素。下面是完整的代码。

from time import sleep

from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait


def init_phantomjs_driver(*args, **kwargs):
    headers = {'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
               'Accept-Language': 'zen-US,en;q=0.9,ur;q=0.8',
               'Referer': 'http://propertymap.sfplanning.org/',

               'Connection': 'keep-alive'
               }

    for key, value in headers.items():
        webdriver.DesiredCapabilities.PHANTOMJS['phantomjs.page.customHeaders.{}'.format(key)] = value

        # webdriver.DesiredCapabilities.PHANTOMJS[
        #     'phantomjs.page.settings.userAgent'] = 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.116 Safari/537.36'

        # driver = webdriver.PhantomJS(*args, **kwargs)


if __name__ == '__main__':
    driver = None
    url = 'http://propertymap.sfplanning.org/'
    url = 'http://50.17.237.182/PIM/'
    input_apn = '1355025'

    # init_phantomjs_driver()
    driver = webdriver.PhantomJS(executable_path='/Setups/phantomjs-1.9.8-macosx/bin/phantomjs')
    # driver = webdriver.Firefox()
    driver.set_window_size(1400, 1000)
    driver.get(url)
    sleep(2)
    # input
    # driver.find_element_by_id('addressInput').send_keys('1344038')
    # elem = driver.find_element_by_id('findButton')
    elem = driver.find_element_by_id('addressInput')
    if elem:
        elem.send_keys(input_apn)

    sleep(5)
    elem = driver.find_element_by_id('findButton')
    if elem:
        elem.click()

    sleep(10)
    myElem = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.ID, 'map_canvas_container')))

    driver.save_screenshot('page.png')
    html = driver.page_source
    soup = BeautifulSoup(html, 'lxml')

    driver.quit()
    entries = soup.select('.reportData')
    print(entries)
