• Python 自动爬取B站视频


    文件名自定义(文件格式为.py),脚本内容:

    #!/usr/bin/env python
    #-*-coding:utf-8-*-
    import requests
    import random
    import time
    
    
    def get_json(url):
    	headers = {
    		'User-Agent': 
    		'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36'
    	}
    
    	params = {
    		'page_size': 10,
    		'next_offset': str(num),
    		'tag': '今日热门',
    		'platform': 'pc'
    	}
    	try:
    		html = requests.get(url,params=params,headers=headers)
    		return html.json()
    		
    	except BaseException:
    		print('request error')
    		pass
    		
    def download(url,path):
    	start = time.time() # 开始时间
    	size = 0
    	headers = {
    		'User-Agent': 
    		'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36'
    	}
    	
    	response = requests.get(url,headers=headers,stream=True) # stream属性必须带上
    	chunk_size = 1024 # 每次下载的数据大小
    	content_size = int(response.headers['content-length']) # 总大小
    	if response.status_code == 200:
    		print('[文件大小]:%0.2f MB' %(content_size / chunk_size / 1024)) # 换算单位
    		with open(path,'wb') as file:
    			for data in response.iter_content(chunk_size=chunk_size):
    				file.write(data)
    				size += len(data) # 已下载的文件大小
    
    
    
    if __name__ == '__main__':
    	for i in range(10):
    		url = 'http://api.vc.bilibili.com/board/v1/ranking/top?'
    		num = i*10 + 1
    		html = get_json(url)
    		infos = html['data']['items']
    		for info in infos:
    			title = info['item']['description'] # 小视频的标题
    			video_url = info['item']['video_playurl'] # 小视频的下载链接
    			print(title)
    
    
    			# 为了防止有些视频没有提供下载链接的情况
    			try:
    				download(video_url,path='videos/%s.mp4' %title)
    				print('成功下载一个!')
    			except BaseException:
    				print('凉凉,下载失败')
    				pass
    		time.sleep(int(format(random.randint(2,8)))) # 设置随机等待时间
    

    爬取效果如下:

    爬取的文件:

    生成一个windows平台可执行exe程序
    工具安装:pip install PyInstaller
    生成exe程序:
    pyinstaller -i test.ico -F Grasp.py
