Python下载图片并保存本地的两种方式

一：使用Python中的urllib类中的urlretrieve()函数，直接从网上下载资源到本地，具体代码：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

import os,stat import urllib.request    img_url="https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1516371301&di=d99af0828bb301fea27c2149a7070" \   "d44&imgtype=jpg&er=1&src=http%3A%2F%2Fupload.qianhuaweb.com%2F2017%2F0718%2F1500369506683.jpg" file_path='D:/book/img' file_name ="pyt"    try:  #是否有这个路径  if not os.path.exists(file_path):  #创建路径   os.makedirs(file_path)   #获得图片后缀  file_suffix = os.path.splitext(img_url)[1]  print(file_suffix)   #拼接图片名（包含路径）  filename = '{}{}{}{}'.format(file_path,os.sep,file_name,file_suffix)  print(filename)   #下载图片，并保存到文件夹中  urllib.request.urlretrieve(img_url,filename=filename)    except IOError as e:  print("IOError") except Exception as e:  print("Exception")

二：利用读写操作写入文件，具体代码：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

import os,stat import urllib.request    for i in range(1,3):  if not os.path.exists("./rym"):   print("不纯在")   os.makedirs("./rym")     else:   print("存在")   os.chmod("D:/imagss",777)         with urllib.request.urlopen("https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1516371301&di=d99af0828b"          "b301fea27c2149a7070d44&imgtype=jpg&er=1&src=http%3A%2F%2Fupload.qianhuaweb.com%2F2017%2F0718%"          "2F1500369506683.jpg", timeout=30) as response, open("./rym/lyj.png"     , 'wb') as f_save:    f_save.write(response.read())    f_save.flush()    f_save.close()    print("成功")
