Python实现从订阅源下载图片的方法

本文实例讲述了Python实现从订阅源下载图片的方法。分享给大家供大家参考。具体如下：

这段代码是基于python 3.4实现的，和python2.X 比起来有了好多差别啊。
这是一个练习，数据源来自网易订阅。代码如下：
代码如下:__author__ = 'Saint'
import os
import urllib.request
import json
from html.parser import HTMLParser
# 从获取的网页内容筛选图片的内容
class MyHtmlParser(HTMLParser):
    links = []
    def handle_starttag(self, tag, attrs):
        if tag == "img":
            if len(attrs) == 0:
                pass
            else:
                for name, value in attrs:
                    if name == "src":
                        self.links.append(value)
class Down(object):
    # 总的目录
    img_path = "E:/saint"
    # 下载目录
    dir = ''
    # 采集源地址
    collect_links = ["http://dy.163.com/v2/media/articlelist/T1374483113516-1", "http://dy.163.com/v2/media/articlelist/T1420776257254-1", "http://dy.163.com/v2/media/articlelist/T1376641060407-1"]
    img_links = "http://dy.163.com/v2/article"
    def handleCollect(self):
        for collect_link in self.collect_links:
            notice = "开始从[" + collect_link + "]采集图片"
            print(notice)
            # 建立下载的目录
            dir_name = collect_link.split("/")[-1]
            self.isDirExists(dir_name)
            dict = self.getListFromSubscribe(collect_link)
            if dict == False:
                print("数据采集失败，是否继续(y/n)")
                op = input();
                if op == "y":
