如何使用Selenium获取停车费?

How to use Selenium to get the parking price?

我正在尝试使用网络抓取来获取 link、https://application.parkbytext.com/accountus/prepay.htm?locationCode=1127 的停车价格。当天的价格是 $2,这就是我想要得到的。我正在使用 python+selenium,但无法获取停车费。下面是我正在使用的代码,但有时我会击中目标,但大多数时候我会收到错误

selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: {"method":"class name","selector":"gwt-RadioButton"}.

有人可以帮忙吗?提前致谢

def downtownparking(driver):
driver.get("https://application.parkbytext.com/accountus/prepay.htm?locationCode=1127")
try:
    ### driver.wait = WebDriverWait(driver, 16)
    ### driver.implicitly_wait(20)
    cr = driver.find_element_by_class_name("gwt-RadioButton")
    dayprice = cr.find_element_by_tag_name("label")
    print (dayprice.text)

页面加载需要时间。目前 webdriver 试图找到一个元素,它还没有出现在 DOM 树中。添加一个 Explicit Wait:

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

cr = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.CLASS_NAME, "gwt-RadioButton"))
)

顺便说一句,请注意,我会改用 input 的名字:

cr = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.XPATH, "//input[@name='periodType']/following-sibling::label"))
)
print(cr.text)  # prints "Day - .00"
