问题描述

我是python的新手，正在尝试学习网络抓取.在学习完一个教程之后，我试图从一个网站中提取价格，但没有打印任何内容.我的代码有什么问题?

I'm very new to python and trying to learn webscraping. Following a tutorial, I'm trying to extract a price from a website but nothing is being printed. What is wrong with my code?

from selenium import webdriver

chrome_path = r"C:\webdrivers\chromedriver.exe"
driver = webdriver.Chrome(chrome_path)
driver.get("https://reservations.airarabia.com/service-app/ibe/reservation.html#/fare/en/AED/AE/SHJ/KHI/07-09-2019/N/1/0/0/Y//N/N")
price = driver.find_elements_by_class_name("fare-and-services-flight-select-fare-value ng-isolate-scope")
for post in price:
        print(post.text)

推荐答案

要打印第一个 title ，必须为所需的visibility_of_element_located()引入 WebDriverWait ，您可以使用以下定位器策略:

To print the first title you have to induce WebDriverWait for the desired visibility_of_element_located() and you can use either of the following Locator Strategies:

• 使用CSS_SELECTOR:

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "isa-flight-select button:first-child span.fare-and-services-flight-select-fare-value.ng-isolate-scope"))).get_attribute("innerHTML"))

使用XPATH:

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//isa-flight-select//following::button[contains(@class, 'button')]//span[@class='fare-and-services-flight-select-fare-value ng-isolate-scope']"))).text)

注意:您必须添加以下导入:

Note : You have to add the following imports :

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

控制台输出两个背对背执行:
