方式1

使用urllib库

import urllib.requestimport os ,staturl = "https://cn.bing.com/th?id=OHR.Lidong2019_ZH-CN0761273672_1920x1080.jpg"try:  urllib.request.urlretrieve(url,filename="/home/baixiaoxu/desk/123.jpg")except IOError as e:  print("IOE ERROR")except Exception as e:  print("Exception")注意：1，获取地址，判断地址是否存在2，本地保存地址，判断存在3，获取远程地址的图片名，或改名"""url = "https://cn.bing.com/th?id=OHR.Lidong2019_ZH-CN0761273672_1920x1080.jpg"file_suffix = os.path.split(url)[1][-20:-1]print(file_suffix)"""

2,使用系统库文件读写操作

import urllib.requestimport os ,statreq = urllib.request.Request(url)file = "/home/baixiaoxu/desk/file-ttttt.jpg"req.add_header('User-Agent','Mozilla/5.0 (Windows NT 6.3; WOW64; rv:51.0) Gecko/20100101 Firefox/51.0')response = urllib.request.urlopen(url)html = response.read()with open(file, 'wb') as f:   f.write(html)

网上的方法

import osos.makedirs('./image/', exist_ok=True)IMAGE_URL = "http://image.nationalgeographic.com.cn/2017/1122/20171122113404332.jpg" def urllib_download():  from urllib.request import urlretrieve  urlretrieve(IMAGE_URL, './image/img1.png')    def request_download():  import requests  r = requests.get(IMAGE_URL)  with open('./image/img2.png', 'wb') as f:    f.write(r.content)def chunk_download():  import requests  r = requests.get(IMAGE_URL, stream=True)    with open('./image/img3.png', 'wb') as f:    for chunk in r.iter_content(chunk_size=32):      f.write(chunk)

整理简单的下载图片

import urllibfrom  urllib import requestimport reresponse = request.urlopen('https://cn.bing.com/')html = response.read()ht = html.decode()pattern = r'bgLink(.*?\.jpg)'compile_re = re.compile(pattern)hh = compile_re.findall(ht)url = hh[0].split('/')[1]download = 'https://cn.bing.com/' + urlurllib.request.urlretrieve(download,filename="/home/baixiaoxu/desk/download.jpg")
