    这篇文章主要介绍了python获取网络图片方法及整理过程详解,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

    方式1

    使用urllib库

    import urllib.request
    import os ,stat
    url = "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.request
    import os ,stat
    
    req = 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 os
    os.makedirs('./image/', exist_ok=True)
    IMAGE_URL = "/uploads/cj/201912/20171122113404332.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 urllib
    from  urllib import request
    import re
    
    response = 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/' + url
    urllib.request.urlretrieve(download,filename="/home/baixiaoxu/desk/download.jpg")
