[中国大学 MOOC 下载助手](https://greasyfork.org/zh-CN/scripts/372684) 3 | ### 功能 4 | 在中国大学 MOOC 的课程学习页面添加批量下载按钮，用来下载视频和文档资源，可以进行下载设置，下载功能由 Aria2 提供，所以下载课程前一定要配置好 Aria2，不然脚本无效，Aria2 的配置请看这篇文章：[如何配置 Aria2 来进行文件下载](https://mofiter.com/2018-08-19/%E5%A6%82%E4%BD%95%E9%85%8D%E7%BD%AE-Aria2-%E6%9D%A5%E8%BF%9B%E8%A1%8C%E6%96%87%E4%BB%B6%E4%B8%8B%E8%BD%BD.html) 。 5 | ### 注意 6 | - 请注意你所在的学习页面的地址，形式为 www.icourse163.org/learn/xxx 这样的才会有批量下载按钮，也就是你必须先参加这门课； 7 | - 第一次使用脚本时，请先点击下载设置，然后填写你要下载视频的保存地址，Mac 上的地址形式为:Users/xxx/Downloads/icourse163，Windows 上的地址形式为:D:\Downloads\icourse163，当然具体保存在哪个文件夹由你自己决定； 8 | - 只在 Chrome 浏览器测试了可以正常使用，其他浏览器能不能用全看缘分； 9 | - 此脚本的目的只为方便个人学习，请勿用于商业用途，否则后果自负。 10 | ## [网易云课堂下载助手](https://greasyfork.org/zh-CN/scripts/371551) 11 | ### 功能 12 | 在网易云课堂的课程详情的课程主页添加下载助手按钮，可以进行下载设置，然后批量下载当前课程，在每一个课时上面也添加了下载按钮，可以单独下载当前课时，下载功能由 Aria2 提供，所以下载课程前一定要配置好 Aria2，不然脚本无效，Aria2 的配置请看这篇文章：[如何配置 Aria2 来进行文件下载](https://mofiter.com/2018-08-19/%E5%A6%82%E4%BD%95%E9%85%8D%E7%BD%AE-Aria2-%E6%9D%A5%E8%BF%9B%E8%A1%8C%E6%96%87%E4%BB%B6%E4%B8%8B%E8%BD%BD.html) 。 13 | ### 注意 14 | - 只有免费课程支持下载，收费课程下载之后无法播放，所以在收费课程的页面没有添加下载按钮； 15 | - 请注意你所在的课程目录页面地址，形式为 study.163.com/course/courseMain.htm?courseId=xxx 这样的才会有下载按钮(如果是 study.163.com/course/introduction.htm?courseId=xxx 这种形式，你需要先参加这门课程)； 16 | - 第一次使用脚本时，请先在下载助手按钮中选择设置，然后填写你要下载视频的保存地址，Mac 上的地址形式为:Users/xxx/Downloads/study163，Windows 上的地址形式为:D:\Downloads\study163，当然具体保存在哪个文件夹由你自己决定； 17 | - 在使用批量下载前，建议先选择任何一个课时，点击课时上面的下载测试一下效果，如果可以成功下载再去使用批量下载； 18 | - Chrome 浏览器和 Firefox 浏览器已测试可正常使用，其他浏览器看缘分； 19 | - 此脚本的目的只为方便个人学习，请勿用于商业用途，否则后果自负。 20 | ## [Udemy 下载助手](https://greasyfork.org/zh-CN/scripts/371552) 21 | ### 功能 22 | 在 Udemy 的课程内容页面添加下载助手按钮，可以进行下载设置，然后批量下载当前课程，在每一个课时上面也添加了下载按钮，可以单独下载当前课时，下载功能由 Aria2 提供，所以下载课程前一定要配置好 Aria2，不然脚本无效，Aria2 的配置请看这篇文章：[如何配置 Aria2 来进行文件下载](https://mofiter.com/2018-08-19/%E5%A6%82%E4%BD%95%E9%85%8D%E7%BD%AE-Aria2-%E6%9D%A5%E8%BF%9B%E8%A1%8C%E6%96%87%E4%BB%B6%E4%B8%8B%E8%BD%BD.html) 。 23 | ### 注意 24 | - 请注意你所在的课程内容页面地址，形式为 www.udemy.com/xxx/learn/v4/content 这样的才会有下载按钮； 25 | - 第一次使用脚本时，请先在下载助手按钮中选择设置，然后填写你要下载视频的保存地址，Mac 上的地址形式为:Users/xxx/Downloads/study163，Windows 上的地址形式为:D:\Downloads\study163，当然具体保存在哪个文件夹由你自己决定； 26 | - 在使用批量下载前，建议先选择任何一个课时，点击课时上面的下载测试一下效果，如果可以成功下载再去使用批量下载； 27 | - Chrome 浏览器、Firefox 浏览器、Safari 浏览器都已测试可正常使用，至于其他浏览器看缘分； 28 | - 此脚本的目的只为方便个人学习，请勿用于商业用途，否则后果自负。 29 | ## [微信公众号文章内视频下载](https://greasyfork.org/zh-CN/scripts/372880) 30 | ### 功能 31 | 在微信公众号的文章页面添加视频下载按钮（如果当前文章中包含视频的话），方便将视频下载到本地使用。下载功能由 Aria2 提供，所以下载视频前一定要配置好 Aria2，不然脚本无效，Aria2 的配置请看这篇文章：[如何配置 Aria2 来进行文件下载](https://mofiter.com/2018-08-19/%E5%A6%82%E4%BD%95%E9%85%8D%E7%BD%AE-Aria2-%E6%9D%A5%E8%BF%9B%E8%A1%8C%E6%96%87%E4%BB%B6%E4%B8%8B%E8%BD%BD.html) 。 32 | ### 注意 33 | - 请先安装 Adblock 等去除广告的浏览器插件([Google 应用商店地址](https://chrome.google.com/webstore/detail/adblock/gighmmpiobklfepjocnamgkkbiglidom) 或 [非 Google 应用商店地址](https://www.chromedownloads.net/extensions/456.html)），因为有些公众号文章内的视频是有广告的，会影响脚本的正常使用； 34 | - 有一小部分视频是无法下载的，就没有提供下载按钮，可以多刷新页面试一下，在没有广告的前提下，如果一直没有下载按钮出现，那应该这个视频就无法下载； 35 | - 视频可能会自动播放，因为只有点击了视频播放，才能拿到视频地址，我已做点击播放后的暂停处理，但可能有时候效果不太好； 36 | - 时间特别长的视频可能下载不全，因为长视频是在播放的过程中分段加载的，每一段的地址都不同，没法一次性拿到全部视频的地址，但短视频应该没影响； 37 | - 第一次使用脚本时，请先点击下载地址设置，然后填写你要下载视频的保存地址，Mac 上的地址形式为:Users/xxx/Downloads，Windows 上的地址形式为:D:\Downloads，当然具体保存在哪个文件夹由你自己决定； 38 | - Chrome 浏览器和 Firefox 浏览器应该可以正常使用，其他浏览器看缘分； 39 | - 视频的版权归原所有者，此脚本的目的只为方便个人学习，请勿用于商业用途，否则后果自负。 40 | ## 如果有任何想法可以加群交流哦~
