1、结果展示

将每一个英雄保存一个文件夹下，把他所有的皮肤保存在他对应的文件夹下(自动生成的你运行爬虫就好了)

2、代码解释

2.1用到第三方的模块

有些自带，有些需要你自己安装，pip install 模块名 就好了，如果有问题可以看我的第三方库导入大全那篇文章，有详细解释

import requests # 请求数据
import os # 操作系统模块，用于创建文件夹
import jsonpath # 用于提取json类型的数据
import re # 正则表达式模块，用于获取皮肤名称
import time # 时间模块，防止爬的太快被封id
import random # 随机数模块，配合time使用

2.2请求头以及主页面js地址

user-agent：故名思意，用户代理，你设置了这个相当于把爬虫程序伪装成浏览器，如果不设置，服务器就会发现你是爬虫，这是最基本的反爬手段之一
hero_list_url：这是通过分析lol官网页面从中提取hero_id的url，如果想学页面分析可以留言我在写一篇分析页面的文章，这个主要教如何爬取

headers = {
    'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.106 Safari/537.36'
           }
hero_list_url = 'https://game.gtimg/images/lol/act/img/js/heroList/hero_list.js'

2.3获得详情页面的函数

写一个获得hero_id的函数找到每一个英雄的详情url为下载做准备，这里我用了列表推导式作为返回值将所有英雄的详情url返回出来方便下载函数调用

def get_id(url):
    response = requests.get(url, headers=headers).json()
    hero_Id = jsonpath.jsonpath(response, '$..heroId')
    time.sleep(random.randint(1, 3))
    base_url = 'http://game.gtimg/images/lol/act/img/js/hero/{}.js'
    return [base_url.format(every_id) for every_id in hero_Id]

2.4定义函数一个提取及下载数据

我直接再代码中进行解释

def get_skin(li1):
      for url in li1: # 遍历列表推导式
        response = requests.get(url, headers=headers)
        result = response.json()['skins'] # 得到关于皮肤的所有信息
        skin_name = [] # 设置空列表用来存储提取到的皮肤名
        skin_url = [] # 设置空列表用来存储提取到的皮肤下载地址
        time.sleep(random.randint(1, 3)) # 随机休眠1到3秒防止被封
        for skin_json in result:
            skin_name.append(skin_json['name']) # 将英雄名保存到上面的空列表之中
            skin_url.append(skin_json['mainImg']) # 将英雄下载地址保存到上面的空列表之中
        hero_folder = 'allhero/' + response.json()['hero']['name'] + response.json()['hero']['title']
        #设置保存的路径
        if not os.path.exists(hero_folder):
            os.mkdir(hero_folder)
        # 判断路径是否存在不存在就创建一个
        for i in range(len(skin_url)):
            if not skin_url[i]=='':
                image_path = hero_folder +'/' + re.findall('\w+',skin_name[i])[0] + '.png' # 具体设置图片的下载路径以及名称和格式
                with open(image_path,'wb')as file:
                    print('正在下载{}'.format(skin_name[i])) # 打印下载进度
                    file.write(requests.get(skin_url[i],headers=headers).content) #下载图片

4、王者荣耀

会遇到英雄名乱码，以及皮肤名乱码等问题，通过selenium获得网页解决，爬取思路很简单，附上结果截图以及源码，为啥我写的博客这么少人看呢
