利用Python进行简单爬虫----学习之二

（先占坑，之后补充）

1.爬取王者荣耀单张皮肤

import urllib.request
import json
import os

v_herolist_url = urllib.request.urlopen("http://pvp.qq.com/web201605/js/herolist.json")
v_herolist = v_herolist_url.read().decode('utf-8')
v_herolist = v_herolist.encode('utf-8')[3:].decode('utf-8')
hero_json = json.loads(v_herolist)
hero_dir = 'D:\图片1\\'
if not os.path.exists(hero_dir):
    os.mkdir(hero_dir)
skin_url = 'http://game.gtimg.cn/images/yxzj/img201606/skin/hero-info/195/195-bigskin-2.jpg'
hero_img = hero_dir + 'aa.jpg'
urllib.request.urlretrieve(skin_url , hero_img)

2.爬取王者荣耀所有英雄皮肤

import urllib.request
import json
import os

v_herolist_url = urllib.request.urlopen("http://pvp.qq.com/web201605/js/herolist.json")
v_herolist = v_herolist_url.read().decode('utf-8')
v_herolist = v_herolist.encode('utf-8')[3:].decode('utf-8')
hero_json = json.loads(v_herolist)
# print(hero_json)
hero_dir = 'D:\图片1\\'

hero_num = len(hero_json)

if not os.path.exists(hero_dir): 
    os.mkdir(hero_dir)

for i in range(hero_num):
    skin_names = hero_json[i]['skin_name'].split('|')
    for j in range(len(skin_names)):
        img_name = hero_dir + str(hero_json[i]['ename']) + '-' + hero_json[i]['cname'] + '-' + skin_names[j] + '.jpg'
        skin_url = 'http://game.gtimg.cn/images/yxzj/img201606/skin/hero-info/' + str(hero_json[i]['ename']) + '/' + str(hero_json[i]['ename']) + '-bigskin-' + str(j+1) + '.jpg'
        urllib.request.urlretrieve(skin_url , img_name)
