执行 flickr.com 搜索 ( https://www.flickr.com/search/?text=lake ) 后,我尝试导航到“人物”部分。

我无法在 <div id="content"> 中找到元素(HTML 图像中从顶部算起的第 6 行)。基本上,无论我尝试什么,NoSuchElementException被抛出。

#! python3

# Saves photos to file from flickr.com using specified search term

import logging
import os
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
import sys

logging.basicConfig(level=logging.DEBUG, format="%(asctime)s - \
%(levelname)s - %(message)s")

def flickr_images():
try:
search_term, number_images = sys.argv[1:]
except:
print("Something went wrong. Command line input must be of \
format: 'filename searchterm numbermessages'")
return

driver = webdriver.Firefox()
driver.get("https://www.flickr.com/")

# wait for page to load
WebDriverWait(driver, 10).until(EC.presence_of_element_located(\
(By.ID, "search-field")))

# find search text field and input search term
driver.find_element_by_id("search-field").send_keys(search_term)

# find and click search button
driver.find_element_by_class_name("search-icon-button").click()

WebDriverWait(driver, 5)

content = driver.find_element_by_id("content")
content.find_element_by_class_name("search-subnav-content")

if __name__ == "__main__":
flickr_images()

enter image description here

最佳答案

我会直接导航到搜索结果页面并等待结果出现:

driver.get("https://www.flickr.com/search/?text=" + search_term)

# wait for the search results to appear
wait = WebDriverWait(driver, 10)
wait.until(EC.visibility_of_element_located((By.CLASS_NAME, "search-photos-results")))

content = driver.find_element_by_id("content")
content.find_element_by_class_name("search-subnav-content")
