selenium python 不能与 phantomjs 一起使用，但可以与 Firefox 一起使用

Question

我尝试使用下面的代码按最近的选项排序，但它给出了以下错误

错误

Message: {"errorMessage":"Unable to find element with css selector 'span.sortedLabel'","request":{"headers":{"Accept":"application/json","Accept-Encoding":"identity","Connection":"close","Content-Length":"107","Content-Type":"application/json;charset=UTF-8","Host":"127.0.0.1:34510","User-Agent":"Python http auth"},"httpVersion":"1.1","method":"POST","post":"{\"using\": \"css selector\", \"value\": \"span.sortedLabel\", \"sessionId\": \"f5246520-f7d4-11e7-a9f4-adb0a497f49e\"}","url":"/element","urlParsed":{"anchor":"","query":"","file":"element","directory":"/","path":"/element","relative":"/element","port":"","host":"","password":"","user":"","userInfo":"","authority":"","protocol":"","source":"/element","queryKey":{},"chunks":["element"]},"urlOriginal":"/session/f5246520-f7d4-11e7-a9f4-adb0a497f49e/element"}}

屏幕截图：可通过屏幕查看

在 Firefox 上一切正常，但在 phantomjs 上却不行。

代码如下：

from selenium import webdriver  # open webdriver for specific browser
from selenium.webdriver.common.keys import Keys  # for necessary browser action
from selenium.webdriver.common.by import By  # For selecting html code
import time

url="https://www.magicbricks.com/property-for-rent/residential-real-estate?proptype=Multistorey-Apartment,Builder-Floor-Apartment,Penthouse,Studio-Apartment,Service-Apartment,Residential-House,Villa&Locality=Bellandur&cityName=Bangalore"
# os.environ['NO_PROXY'] = '127.0.0.1'
# driver = webdriver.Firefox()
driver = webdriver.PhantomJS(executable_path=r'D:\Setup\NEW SOFTWARE\Python\phantomjs-2.1.1-windows\bin\phantomjs.exe')

driver.get(url)
try:
    #driver.find_element_by_id("sort4").click()
    driver.find_element_by_css_selector("span.sortedLabel").click()
    driver.find_element_by_id("sort4").click()
    time.sleep(3)
    html = driver.page_source
except Exception as e:
    print(str(e))

有什么解决办法吗？

Answer 1

您似乎没有实施任何超时。 FF 和 PahntomJS 在页面被认为完全加载时可能会执行不同的操作，这可能导致 FF 工作正常而 PhantomJS 不能正常工作的情况。要快速调试此行为，只需在您的阳离子之间添加一些隐式等待，看看它们是否有帮助。如果可行，请将隐式等待替换为适当的显式等待。

隐式等待 10 秒的示例：

driver.implicitly_wait(10) # seconds
