league_skin自动更新软件
用python编写的一个league_skin自动更新脚本，通过检测当前目录是否存在文件以及相应的网络版本号对比检查更新，若存在更新则进行下载解压并覆盖原有文件。纯文本代码如下:
import requests
from lxml import etree
import os
import time
import zipfile
import shutil#删除模块
#v1.1
def download(url, filename):
start = time.time() #下载开始时间
try:
response = requests.get(url, stream=True)# 来获取服务器的原始套接字响应
size = 0# 初始化已下载大小
chunk_size = 1024# 每次下载的数据大小
content_size = int(response.headers['content-length'])# 下载文件总大小
if response.status_code == 200: #判断是否响应成功
print('Start download,:{size:.2f} MB'.format(size = content_size / chunk_size /1024)) #开始下载，显示下载文件大小
with open(filename, 'wb') as f: #显示进度条
for data in response.iter_content(chunk_size=chunk_size): #边下载边存储
f.write(data)
size += len(data)
print('\r'+'[下载进度]:%s%.2f%%' % ('>'*int(size*50/ content_size), float(size / content_size * 100)) ,end=' ')
end = time.time() #下载结束时间
print('Download completed!,times: %.2f秒' % (end - start))#输出下载用时时间
except:
print('可能存在网络问题，下载失败，请重试')
os.system('pause')
exit()
def del_dir(): #删除原有文件夹
path = os.getcwd()
files = os.listdir(path)
try:
for file in files:
if 'MODSKIN' in file:
path = path + '\\' + file
print(path)
shutil.rmtree(path)
print('成功删除'+ path)
except:
print('删除旧文件夹失败或未找到')
def unzip_file(filename, dir):
if(zipfile.is_zipfile(filename)):
fz = zipfile.ZipFile(filename, 'r') #读取zip文件
for file in fz.namelist():#返回压缩包内所有文件名的列表。
fz.extract(file, dir) #将zip文档内的指定文件解压到当前目录
print('解压成功')
else:
print('解压失败')
def start():
url = 'http://leagueskin.net/p/download-mod-skin-2020-chn'
try:
result = requests.get(url).content
except:
print('无法连接网络')
exit()
soup = etree.HTML(result)
down_url = soup.xpath('//a[@id="link_download3"]/@href')# 内容提取
down_url = down_url
filename = str(down_url).split('/')
filename = filename
dir_name = filename.replace('.zip', '')
if not os.path.exists(dir_name):
print("开始处理，请等待")
del_dir()
download(down_url, filename)
dir = os.path.join(os.getcwd(), dir_name)
unzip_file(filename, dir)
try:
print('尝试删除压缩包')
file_path = os.path.join(os.getcwd(), filename)
print(file_path)
os.remove(file_path)
print('删除成功')
except:
print('删除失败')
else:
print("没有更新的版本")
os.system('pause')
if __name__ == '__main__':
start()
