前言

英雄联盟有那么多皮肤，不知道你喜欢那一款呢？我最喜欢的瑞文的兔女郎，不管你喜欢那款皮肤，Python都能让你尽情爬取并保存到文件夹，让你拥有视觉盛宴。

首先导入库:

import requests import json from urllib import parse import os

初始化变量和下载HTML

class GetLolSkin(object): """抓取LOL英雄皮肤""" def __init__(self): """初始化变量""" self.hero_url = 'https://lol.qq.com/biz/hero/champion.js' self.hero_detail_url = 'http://lol.qq.com/biz/hero/' self.skin_folder = 'skin' self.skin_url = 'https://ossweb-img.qq.com/images/lol/web201310/skin/big' @staticmethod def get_html(url): """下载html""" request = requests.get(url) request.encoding = 'gbk' if request.status_code == 200: return request.text else: return "{}"

获取英雄的详细信息

def get_hero_list(self): """获取英雄的详细信息""" hero_js = self.get_html(self.hero_url) # 删除左右的多余信息，得到json数据 out_left = "if(!LOLherojs)var LOLherojs={};LOLherojs.champion=" out_right = ';' hero_list = hero_js.replace(out_left '').rstrip(out_right) return json.loads(hero_list) def get_hero_info(self hero_id): """获取英雄的详细信息""" # 获取js详情 detail_url = parse.urljoin(self.hero_detail_url hero_id '.js') detail_js = self.get_html(detail_url) # 删除左右的多余信息，得到json数据 out_left = "if(!herojs)var herojs={champion:{}};herojs['champion'][%s]=" % hero_id out_right = ';' hero_info = detail_js.replace(out_left '').rstrip(out_right) return json.loads(hero_info)

下载皮肤图片

def download_skin_list(self skin_list hero_name): """下载皮肤列表""" # 循环下载皮肤 for skin_info in skin_list: # 拼接图片名字 if skin_info['name'] == 'default': skin_name = '默认皮肤' else: if ' ' in skin_info['name']: name_info = skin_info['name'].split(' ') skin_name = name_info[0] else: skin_name = skin_info['name'] hero_skin_name = hero_name '-' skin_name '.jpg' self.download_skin(skin_info['id'] hero_skin_name) def download_skin(self skin_id skin_name): """下载皮肤图片""" # 下载图片 img_url = self.skin_url skin_id '.jpg' request = requests.get(img_url) if request.status_code == 200: print('downloading……%s' % skin_name) img_path = os.path.join(self.skin_folder skin_name) with open(img_path 'wb') as img: img.write(request.content) else: print('img error!')

创建文件夹保存图片

def make_folder(self): """初始化，创建图片文件夹""" if not os.path.exists(self.skin_folder): os.mkdir(self.skin_folder) def run(self): # 获取英雄列表信息 hero_json = self.get_hero_list() hero_keys = hero_json['keys'] # 循环遍历英雄 for hero_id hero_code in hero_keys.items(): hero_name = hero_json['data'][hero_code]['name'] hero_info = self.get_hero_info(hero_id) if hero_info: skin_list = hero_info['result'][hero_id]['skins'] # 下载皮肤 self.download_skin_list(skin_list hero_name) else: print('英雄【%s】的皮肤获取有问题……' % hero_name)

程序执行入口

# 程序执行入口 if __name__ == '__main__': lol = GetLolSkin() # 创建图片存储文件 lol.make_folder() # 执行脚本 lol.run()

是不是感觉跟爬取其他图片的套路一样？是的，其实你只有懂一个就可以写很多类似的代码，多多练习，让你更加牢记d
