本文實例講述了Python實現從訂閱源下載圖片的方法。分享給大家供大家參考。具體如下：

這段代碼是基于python 3.4實現的，和python2.X 比起來有了好多差別啊。
這是一個練習，數據源來自網易訂閱。代碼如下：
代碼如下:__author__ = 'Saint'
import os
import urllib.request
import json
from html.parser import HTMLParser
# 從獲取的網頁內容篩選圖片的內容
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):
    # 總的目錄
    img_path = "E:/saint"
    # 下載目錄
    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 = "開始從[" + collect_link + "]采集圖片"
            print(notice)
            # 建立下載的目錄
            dir_name = collect_link.split("/")[-1]
            self.isDirExists(dir_name)
            dict = self.getListFromSubscribe(collect_link)
            if dict == False:
                print("數據采集失敗，是否繼續(y/n)")
                op = input();
                if op == "y":
