方案二:获取源链接后下载
附录:HumanVid链接
方案一:转换链接为download模式
将下载链接的后缀加入 /download 然后用下面的脚本下载:
import argparse
import json
import os
import timeimport requests
import tqdm
from pexels_api import APIPEXELS_API_KEY = os.environ['PEXELS_KEY']
MAX_IMAGES_PER_QUERY = 100
RESULTS_PER_PAGE = 10
PAGE_LIMIT = MAX_IMAGES_PER_QUERY / RESULTS_PER_PAGEdef get_sleep(t):def sleep():time.sleep(t)return sleepdef main(args):sleep = get_sleep(args.sleep)api = API(PEXELS_API_KEY)query = args.querypage = 1counter = 0photos_dict = {}# Step 1: Getting urls and meta informationwhile page <= PAGE_LIMIT:api.search(query, page=page, results_per_page=RESULTS_PER_PAGE)photos = api.get_entries()for photo in tqdm.tqdm(photos):photos_dict[photo.id] = vars(photo)['_Photo__photo']counter += 1if not api.has_next_page:breakpage += 1sleep()print(f"Finishing at page: {page}")print(f"Images were processed: {counter}")# Step 2: Downloadingif photos_dict:os.makedirs(args.path, exist_ok=True)# Saving dictwith open(os.path.join(args.path, f'{query}.json'), 'w') as fout:json.dump(photos_dict, fout)for val in tqdm.tqdm(photos_dict.values()):url = val['src'][args.resolution]fname = os.path.basename(val['src']['original'])image_path = os.path.join(args.path, fname)if not os.path.isfile(image_path): # ignore if already downloadedresponse = requests.get(url, stream=True)with open(image_path, 'wb') as outfile:outfile.write(response.content)else:print(f"File exists: {image_path}")if __name__ == '__main__':parser = argparse.ArgumentParser()parser.add_argument('--query', type=str, required=True)parser.add_argument('--path', type=str, default='./results_pexels')parser.add_argument('--resolution', choices=['original', 'large2x', 'large','medium', 'small', 'portrait','landscape', 'tiny'], default='original')parser.add_argument('--sleep', type=float, default=0.1)args = parser.parse_args()main(args)
方案二:获取源链接后下载
例如这个链接:
https://www.pexels.com/video/5901660/
浏览器打开:
然后单击右键,获取视频链接地址:
这个链接地址就是原视频的链接地址了,因此可以直接wget下载,也可以用response下载。
那么用脚本如何批量下载呢?以下是源代码:
