Python 程序下载经办人照片

进行图片下载，需要提前准备好下载图片的存放文件夹；

python在与文件、目录打交道时，少不了os模块。os模块包含普遍的操作系统功能。

os.path.exists(filepath)——检验指定的对象是否存在；os.mkdir(filepath)——创建目录；os.path.join(path, name)——连接目录和文件名

---

 import os
 import sys

 #city_id = sys.argv[1]
 city_id = 660

 def check_make_image_floder(filepath):
     if not os.path.exists(filepath):
         os.makedirs(filepath)
 image_floder = "C:\\Users\\admin\\Desktop\\%s" %city_id
 check_make_image_floder(image_floder)

urllib.urlretrieve(url, filename)—将远程数据下载到本地指定路径

---

 import os
 import sys
 import urllib

 #city_id = sys.argv[1]
 city_id = 660

 def check_make_image_floder(filepath):
     if not os.path.exists(filepath):
         os.makedirs(filepath)
 image_floder = "C:\\Users\\admin\\Desktop\\%s" %city_id
 check_make_image_floder(image_floder)

 filename = "660170120991757571.jpg"
 dest_dir = os.path.join(image_floder,filename)

 url_example = 'http://xxx.xxx.xx.xxx:xxxx/REST/docService?timestamp=1450063392000&organId=xxxxx&busiType=1&appId=crmlog&staffNo=xxTEST200&filename=660/16000004/13298809/660170120991757571.jpg&method=get&password=crmlog1452&latnId=660&signature=731ccc37de5e48dc69bb9ba3xxxxxxxxx&version=001'
 def crawl_image(url_example,dest_dir):
     urllib.urlretrieve(url_example,dest_dir)

 crawl_image(url_example,dest_dir)

进行文件下载前，先替换latnId；

 import os
 import sys
 import urllib
 import re

 #city_id = sys.argv[1]
 city_id = 660

 url_example = 'http://xxx.xxx.xx.xxx:xxxx/REST/docService?timestamp=1450063392000&organId=2222&busiType=1&appId=crmlog&staffNo=xxTEST200&filename=663/16000004/13298809/6601701209917xxxxx.jpg&method=get&password=crmlog1452&latnId=663&signature=731ccc37de5e48dc69bb9ba34b9f3188&version=001'
 pattern = re.compile(r'latnId=\d{2,3}')
 image_url01 = re.sub(pattern, 'latnId='+str(city_id).strip(), url_example)

 def check_make_image_floder(filepath):
       if not os.path.exists(filepath):
          os.makedirs(filepath)
 image_floder = "C:\\Users\\admin\\Desktop\\%s" %city_id
 check_make_image_floder(image_floder)

 def crawl_image(image_url,dest_dir):
     urllib.urlretrieve(image_url,dest_dir)

 with open("C:\\Users\\admin\\Desktop\\%sdata.txt"%city_id,'r') as f:
     lines = f.readlines()
     lists = image_url01.split('&')
     for list in lists:
         if list.startswith('filename'):
             for line in lines:
                 image_url02 = re.sub(list, 'filename='+line.strip(), image_url01)
                 results = line.split('/')
                 image_name_ex = results.pop()
                 image_info = urllib.urlopen(image_url02.strip())
                 if image_info.getcode() == 200:
                     image_url = image_url02.strip()
                     dest_dir = os.path.join(image_floder,image_name_ex.strip())
                     crawl_image(image_url,dest_dir)
                     print image_url + " write sucess !"
