-------------------------------------------------------------------------------- 1 | ### 依赖环境 2 | 3 | 本工具依赖于 `Ruby` 执行环境。 4 | 5 | `Linux` 或 `OS X` 环境，可以通过 `RVM` 或者 `rbenv` 来安装 `Ruby`，当然，如果只是临时使用，也可以用系统自带的。 6 | 7 | #### RVM 8 | 9 | `RVM` [官方地址](http://rvm.io/)。 10 | 11 | ```bash 12 | # 安装 13 | gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB 14 | curl -sSL https://get.rvm.io | bash -s stable 15 | 16 | rvm reload 17 | rvm list known 18 | rvm install 2.5.1 19 | rvm use 2.5.1 —default 20 | 21 | # 更新 22 | rvm get stable 23 | ``` 24 | 25 | #### rbenv 26 | 27 | `rbenv` [官方地址](https://github.com/rbenv/rbenv)，下面以 `OS X` 平台来演示如何安装 `Ruby`。 28 | 29 | 30 | ```bash 31 | # 安装 32 | brew update 33 | brew install rbenv ruby-build 34 | 35 | rbenv init 36 | rbenv versions 37 | rbenv install 2.5.1 38 | 39 | # 更新 40 | brew upgrade rbenv ruby-build 41 | ``` 42 | 43 | 了解更多 `Ruby` 相关知识，可以参考 [Ruby 编程手札](https://github.com/jameszhan/notes-ruby)。 44 | 45 | #### 本工具依赖的 `gem` 46 | 47 | ```bash 48 | gem install nokogiri 49 | gem install faraday 50 | gem install thor 51 | ``` 52 | 53 | ### 下载喜马拉雅付费音频 54 | 55 | > 本工具只能下载你本人已经付费过的喜马拉雅专辑，也就是指定的 `uid` 已经购买了该专辑。 56 | 57 | #### 如何获取你的 `uid` 和 `token` 58 | 59 | 在电脑 `Chrome` 上随便打开一个喜马拉雅付费音频，并打开开发者工具(Developer Tools)，点击音频播放按钮， 60 | 在网络 `XHR` 中锁定检查支付的请求 `URL`，该 `URL` 以 `https://mpay.ximalaya.com/mobile/track/pay/` 开始。 61 | 此 `URL` 就包含你想要的 `uid` 和 `token`。 62 | 63 | > 注意：VIP 和 自购是不同的 `token` 64 | 65 | ![uid_token.png](./uid_token.png) 66 | 67 | ```bash 68 | export XMLY_UID=YOUR_UID 69 | export XMLY_TOKEN=YOUR_TOKEN 70 | ``` 71 | 72 | #### 激活工具 73 | 74 | ```bash 75 | chmod +x xmly 76 | ./xmly 77 | 78 | # Commands: 79 | # xmly album # xmly album 4417201 keji /tmp 80 | # xmly download # xmly download 26903700,27251627 /tmp 81 | # xmly help [COMMAND] # Describe available commands or one specific command 82 | ``` 83 | 84 | ### 示例演示 85 | 86 | #### 下载专辑 87 | 88 | 下载[卓老板聊科技第二季](https://www.ximalaya.com/keji/4417201/)。 89 | 90 | ```bash 91 | mkdir ~/keji4417201 92 | ./xmly album 4417201 keji ~/keji4417201 93 | ``` 94 | 95 | #### 批量下载多个音频 96 | 97 | 这个命令适合某些音频下载失败时候使用，音频 `ID` 可以从专辑下载的失败日志中拿到。 98 | 99 | 音频ID | 名称 | URL 100 | --- | --- | --- 101 | 45213979 | 发现天使粒子是怎么回事 |
