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")
