Little knowledge , Great challenge ！ This article is participating in “ A programmer must have a little knowledge ” Creative activities .

Preface

Today, I'll take you to climb the full set of skin of the king's glory , I don't say much nonsense , Just start ~

development tool

Python edition ： 3.6.4

Related modules ：

requests modular ;

urllib modular ;

As well as some Python Built in modules .

Environment building

install Python And add to environment variable ,pip Install the relevant modules required .

Thought analysis

1、 Open the official King's glory wallpaper website Web site address ：pvp.qq.com/web201605/w…

2、 Shortcut key F12, Call out the console to capture packets

3、 Find the right link and analyze

4、 View the return data format

5、 analysis url link

6、 see url Whether the content is the required picture , The discovery is actually a thumbnail

7、 Then analyze the website , Just click on a piece of wallpaper , View links in the specified format

8、 Find the target address

9、 Analyze the differences between the target link and the thumbnail link

 thumbnail ：http://shp.qpic.cn/ishow/2735090714/1599460171_84828260_8311_sProdImgNo_6.jpg/200

 Goal map ：http://shp.qpic.cn/ishow/2735090714/1599460171_84828260_8311_sProdImgNo_6.jpg/0
 Copy code 

You can know , Will specify the format of the thumbnail address after 200 Replace with 0 It's the real picture of the target
