PEXELS网站上的图片素材，质量很高，可以免费用于个人和商业用途，但是搜索功能不能用中文，这里结合百度翻译API完成搜索路径的构建。由于百度翻译API为个人申请使用，这里用XXX代替，需要的童鞋可以自己申请免费key。代码如下：
from bs4 import BeautifulSoup
import requests
import json
import random
import hashlibappid = 'XXXXX' #这里换成自己申请的
key = 'XXXXX' #这里换成自己申请的img_list=[]
save_path = 'F://photos/'
url_path = 'https://www.pexels.com/search/'
headers ={'accept':'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8','user-agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.112 Safari/537.36'

url = url_path + Chinese_to_English(word)+'/'
wb_data = requests.get(url,headers=headers)
soup = BeautifulSoup(wb_data.text,'lxml')
imgs = soup.select('article > a > img')
#print(soup.prettify())
