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:

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:

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")
