我想在自动化完成后将电影/连续剧的 IMDB 评级打印到终端

Question

我使用 Google 搜索来查找该元素，因为它似乎比 IMDB 更容易导航。

import selenium.webdriver as webdriver
print("This program finds the imdb rating of a movie or TV series!!!")

def get_results(search_term):
    url="https://www.google.com"
    browser=webdriver.Safari()
    browser.get(url)
    search_box= browser.find_element_by_id("lst-ib")
    search_box.send_keys(search_term)
    search_box.submit()
    links = browser.find_element_by_id("//div[@class = 'slp f']/text()")#this line is problematic, should i use xpath?how?
    print(links)

search_key=input("Enter the movie name : ")
get_results("what is the imdb rating of "+search_key)

这是错误...

This program finds the imdb rating of a movie or TV series!!!
Enter the movie name : inception
Traceback (most recent call last):
  File "web1.py", line 15, in <module>
    get_results("what is the imdb rating of "+search_key)

    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.NoSuchElementException: Message: An element could not be located on the page using the given search parameters.

请具体说明。谢谢！

我对你的代码做了一些修改，它可以工作。添加了显式等待并更改了选择器。

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


print("This program finds the imdb rating of a movie or TV series!!!")

def get_results(search_term):
    url = "https://www.google.com"
    browser = webdriver.Safari()
    browser.get(url)
    search_box= browser.find_element_by_id("lst-ib")
    search_box.send_keys(search_term)
    search_box.submit()
    rating = WebDriverWait(browser, 5).until(
    EC.presence_of_element_located((By.XPATH, '//*[@id="rso"]/div/div/div[1]/div/div/div[1]/div/div[2]')))
    print(rating.text)
    links = browser.find_elements_by_xpath('//h3/a')
    first_link = links[0].get_attribute('href')
    print(first_link)
    browser.quit()

search_key=input("Enter the movie name : ")
get_results("what is the imdb rating of "+search_key)

希望这会对您有所帮助。
