8 | 请使用篡改猴|油猴插件 Tampermonkey 来进行安装
9 |
10 | 最新功能(v 0.30)：可通过配置ocr服务自动识别登录验证码；可自动下载课件。
11 |
12 | ## 一键安装
13 |
14 | ### 第一步
15 | **请先安装 [Tampermonkey](https://www.tampermonkey.net/) 浏览器扩展**
16 |
17 | 各浏览器具体链接：
18 |
19 | [](https://chromewebstore.google.com/detail/tampermonkey/dhdgffkkebhmkfjojejmpbldmpobfkfo)
20 | [](https://addons.mozilla.org/zh-CN/firefox/addon/tampermonkey/)
21 | [](https://microsoftedge.microsoft.com/addons/detail/%E7%AF%A1%E6%94%B9%E7%8C%B4/iikmkjmpaadaobahmlepeloendndfphd)
22 | [](https://apps.apple.com/us/app/tampermonkey/id1482490089)
23 | [](https://addons.opera.com/zh-cn/extensions/details/tampermonkey-beta/)
24 |
25 | ### 第二步
26 | 第一次安装需要打开浏览器的开发者模式。
27 |
28 | Edge浏览器: 地址栏输入edge://extensions/并回车，打开开发人员模式
29 | 
30 |
31 | Chrome浏览器: 地址栏输入chrome://extensions/并回车，打开开发人员模式
32 |
33 | 其他浏览器同理。
34 |
35 | ### 第三步
36 | 点击下面的按钮直接安装最新版本：
37 |
38 | [](https://greasyfork.org/zh-CN/scripts/546406-%E5%8D%97%E5%A4%A7lms%E6%99%BA%E6%85%A7%E6%95%99%E8%82%B2%E5%B9%B3%E5%8F%B0-mooc%E5%A2%9E%E5%BC%BA/)
39 |
40 | ## 自动更新
41 |
42 | 脚本已配置自动更新功能
43 |
44 | ## 配置OCR验证码识别
45 | 如果需要自动识别登录验证码，请按以下步骤操作（如已有相应API接口可直接在第二步填入）：
46 |
47 | ### 第一步
48 | 下载startocr.bat文件并保存在本地任意目录，双击运行，等待命令行窗口提示`启动ddddocr验证码识别服务...\\
49 | 服务地址: http://127.0.0.1:5000`即运行成功，无需关闭该 cmd 窗口。
50 |
51 | 该脚本为傻瓜式一键操作脚本，如该批处理脚本无法正常运行，请手动运行`startocr.py`文件，确保已安装 Python3 和 ddddocr 库。
52 |
53 | ### 第二步
54 | 在登录页面 authserver.nju.edu.cn 的右侧菜单开启自动识别，并填入API地址`http://127.0.0.1:5000/ocr`。
55 |
56 | ## 功能简介
57 | 1. ▶️解除自动暂停，可后台播放
58 | 2. 🚫解除禁用右键，不可跳转进度条等限制
59 | 3. ⏩自动加速视频课程完成进度
60 | 4. ⏭️播放完成后自动播放下一个视频，跳过无视频页面
61 | 5. 🚀侧边菜单可控制多种倍速0.1x/1x/3x/16x
62 | 6. 🚀可自动识别登录验证码（需配置OCR服务）
63 |
64 | ## 使用演示
65 | 其他功能自动开启，如需倍速请按下图从右侧菜单选择所需倍速
66 | 
67 |
68 | ## 温馨提示
69 | - 当您在对应网站看到页面右侧蓝色隐藏倍速按钮时，代表脚本已经成功安装并生效。
70 |
71 | - 如遇页面卡顿/功能失效等问题，以及“系统繁忙”提示时，请立即通过 `ctrl + shift + R` 刷新缓存，以及 `F5` 强制刷新。
72 |
73 | - 建议遵循适度使用和非必要不使用的准则。使用过程中您可随时选择关闭该脚本。由使用此脚本导致的任何问题请自行承担风险。
74 |
75 | - 欢迎反馈问题和建议！
76 |
77 | ## TODO List
78 |
79 | 📋 **功能扩展计划**
80 |
81 | - ☐
82 |
83 |
84 | **⭐ 如果这个脚本对您有帮助，请给个 Star 支持一下！(\*╹▽╹\*)**
