中山大学(SYSU)选课系统的抢课软件 2 | 3 | ## 这是什么？ 4 | 5 | SYSU Course Selector(SCS)，是一个基于 python3 的抢课软件，系我在贵校就读三年来，从未选上理想的课程，愤然而作。 6 | 7 | 实践证明，有了 SCS 的帮助，我的确选到了我想要的课程。 8 | 9 | ## 如何使用？ 10 | 11 | 0. 你必须把源码拉到本地，执行 `git clone https://github.com/Siriussee/sysu-course-selector.git`； 12 | 1. 我只提供了源代码，所以首先你得准备一个 [python 3.7.0](https://www.python.org/downloads/)； 13 | 2. 安装对应的依赖 `pip install -r requirements.txt`； 14 | 3. 根据你的实际情况修改 `info.py`； 15 | 4. 运行主程序 `python main.py`； 16 | 5. 根据 `code.bmp` 中的验证码，输入验证码； 17 | 6. 输入你想选的课的课程号； 18 | 7. 别关掉它，耐心等待。 19 | 20 | 需要注意的是，这个抢课软件也仅仅是在有人退课的情况下为你尽快抢选这门课程。因此，它不能保证你一定能够选上这门课——说不定大家都不退课，或者有别人也用了这个软件捷足先登了呢。 21 | 22 | ## 我是真的不会用怎么办？ 23 | 24 | 请带上一杯奶茶找我，我帮你。如果我们素未谋面，请在 issue 留下您的邮箱。 25 | 26 | ## 出现了bug？ 27 | 28 | 请在提交 issue 时附带运行时生成的 `log3.log`，这样能方便我定位错误。 29 | 30 | ## 更新计划 31 | 32 | - 打包成二进制可执行文件（没什么动力）。 33 | - 我的代码只在SE专业的专选课程进行过测试，希望能够将适用性扩展到更多专业和更多课程类别。 34 | - 二维码的机器识别。 35 | - TBD 36 | -------------------------------------------------------------------------------- /code.bmp: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/Siriussee/sysu-course-selector/631233df0b75f6e771a756f676cffe02d45c8229/code.bmp -------------------------------------------------------------------------------- /info.py: -------------------------------------------------------------------------------- 1 | #
