GUI页面，使用tkinter写了GUI，方便使用。 15 | >4. ~~异步处理~~ 16 | >5. ~~ip隧穿实现高速爬取~~ 17 | 18 | 19 | ## 使用方法 20 | 21 | 1. 将文件clone到本地`git clone` 22 | 2. cd到解压的文件夹 `pip install -r requirements.txt` 23 | 3. `python -m GUI.py` 24 | 25 | ## 注意事项 26 | 1. 打开GUI页面之前检查程序同目录下有没有“data.txt”,"cookies_string.txt"文件，如果没有可以自己建一个(GUI页面插入也会自动建)，如果没有这两个文件会报错。 27 | 2. 使用自动获取cookie的功能时确保文件不处于中文路径上 (opencv在中文路径上会报错) 28 | -------------------------------------------------------------------------------- /test3.py: -------------------------------------------------------------------------------- 1 | import threading 2 | import time 3 | from getCommond import Calculator,getcookie 4 | import os 5 | def startMultiprocess(): 6 | a = [] 7 | # path = os.path.split(os.path.realpath(__file__))[0]+r"data.txt" 8 | with open(os.path.split(os.path.realpath(__file__))[0]+r"/data.txt",'r',encoding='utf-8')as f: 9 | a.append(f.read()) 10 | cookie = getcookie() 11 | threads = [] 12 | b = a[0].split('\n') 13 | for i in range(len(b)): 14 | c = b[i].split(',') 15 | if(len(c)>1): 16 | cal = Calculator(cookie=cookie,catename=c[0],rifle_name=c[1],minprice=float(c[2]),maxprice=float(c[3]),minmosun=float(c[4]),maxmosun=float(c[5])) 17 | t = threading.Thread(target=cal.buy_until_complete) 18 | threads.append(t) 19 | 20 | for t in threads: 21 | t.start() 22 | time.sleep(1) 23 | 24 | 25 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | MIT License 2 | 3 | Copyright (c) 2022 LRJ 4 | 5 | Permission is hereby granted, free of charge, to any person obtaining a copy 6 | of this software and associated documentation files (the "Software"), to deal 7 | in the Software without restriction, including without limitation the rights 8 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 9 | copies of the Software, and to permit persons to whom the Software is 10 | furnished to do so, subject to the following conditions: 11 | 12 | The above copyright notice and this permission notice shall be included in all 13 | copies or substantial portions of the Software. 14 | 15 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 16 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 17 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
