Foreword

Hello there. Here is a Python reptile from the entry to abandon a series of articles. I SunriseCai.

This article describes the use of crawlers download all the heroes of the League of skin.

League Heroes Gallery: https://lol.qq.com/data/info-heros.shtml

1. Article Ideas

League of Legends website look, multi-map as follows:

• Home (one page)
  
• Skin page (two pages)
  
• Pictures (three pages)
  

It can be seen above a few pictures, which set down is still a Russian doll! ! !

1. Access home page (a page) to get all heroes links (two pages)
2. Access hero Link (two pages) to obtain image link (three pages)
3. Access image link (three pages) , save the image.

So, the next is to be implemented in code download pictures.

2. Request + page analysis

Added to the above, this article's request to be home for https://lol.qq.com/data/info-heros.shtml .

2.1 Request Home

浏览器打开 网站首页，点击F12，进入开发者模式。看看页面结构，发现了二级页面的链接就在<li>标签里面。perfect ！！！那接下来就是去 请求网页 。

首页请求代码：

import requests

url = 'https://lol.qq.com/data/info-heros.shtml'
headers = {
    'User-Agent': 'Mozilla/5.0'
}
res = requests.get(url, headers=headers)
if res.status_code == 200:
    print(res.text)
else:
    print('your code is fail')

执行上述代码之后，发现并没有上图中的<li>标签的内容，这是怎么回事呢？<li>标签的内容极有可能是通过xhr异步加载出来的的文件，咱们来抓包看看！！

• 再次请求首页时候发现，在xhr这里，有一个hero_list.js文件，翻译过来就是英雄列表。

• 看到hero_list.js的url为 ：https://game.gtimg.cn/images/lol/act/img/js/heroList/hero_list.js
  

• 点击之后，发现这正是我们需要的内容！！！
  
  下面请求hero_list.js。

请求的代码很简单，只需要将上面的代码的url更改为 https://game.gtimg.cn/images/lol/act/img/js/heroList/hero_list.js 即可。

未完待续。。。
