工欲善其事  必先利其器

要想玩好LOL，那了解所有英雄的技能必然是其最基本的。所以此爬虫就应运而生

运行环境

python 3.7

此爬虫所用的库有

requests (获取网页信息)

openpyxl (Excel相关操作)

pymysql (MySQL数据库相关操作)

re (正则)

代码

下面有已打包为EXE的程序，可直接使用

主要代码

import requests

import re

import openpyxl

import pymysql

def get_html(hero):

headers = {

'Referer': 'http://lol.qq.com/web201310/info-defail.shtml?id=' + hero,

'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36',

}

url = 'http://lol.qq.com/biz/hero/' + hero + '.js'

# print(url)

response = requests.get(url, headers=headers)

response = response.text

return response

def hero_info(response):

# 英雄名称

hero_name = re.findall(r'"name":"(.*?)","title"', response, re.S)[0]

hero_title = re.findall(r'"title":"(.*?)","tags"', response, re.S)[0]

# 技能(QWER)

hero_spells = re.findall(r'"spells":(.*?),"passive"', response, re.S)[0]

# 技能名称

hero_spells_name = re.findall(

# 技能主被动

# 被动技能

# 被动技能名称

r'"name":"(.*?)","description"', hero_passive, re.S)[0]

# 技能描述

r'"description":"(.*?)","image"', hero_passive, re.S)[0]

# 技能主被动

# print(sql)

# 执行sql语句

cursor.execute(sql)

# 提交到数据库执行

db.commit()

db.close()

return True

def main():

her_encode.append(i)

her.append(her_encode)

save_to_excel(her)

#save_to_mysql(her)

if __name__ == '__main__':

main()

获取英雄数据文件

运行此文件后会在当前目录下生产hero的数据文件

import requests

import re

headers = {

'Referer': 'https://lol.qq.com/data/info-defail.shtml?id=Aatrox',

'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36',

}

response = requests.get('https://lol.qq.com/biz/hero/champion.js', headers=headers)

keys = re.findall(r'"keys":{(.*?)},"data"',response.text,re.S)

keys = keys[0]

keys = keys.split(',')

with open('hero','w') as f:

for key in keys:

f.write(key)

f.write('\n')

print(key)

_如果想要保存到MySQL，请先创建MySQL数据库，然后用下面的代码创建表，最后取消主代码save_tomysql(her)的注释即可

创建数据表代码

#!/usr/bin/python3

import pymysql

# 打开数据库连接

db = pymysql.connect("localhost","root","123456","python_mysql" )

# 使用 cursor() 方法创建一个游标对象 cursor

cursor = db.cursor()

# 使用 execute() 方法执行 SQL，如果表存在则删除

cursor.execute("DROP TABLE IF EXISTS EMPLOYEE")

# 使用预处理语句创建表

sql = """CREATE TABLE lolheroinfo (

英雄称号  CHAR(255),

英雄名称 CHAR(255),

被动技能 CHAR(255),

主动技能 varchar(999)

)

"""

cursor.execute(sql)

# 关闭数据库连接

db.close()
