去做

• 讲座（视频、字幕、幻灯片）
• 读数
• 测验
• Jupyter 笔记本

安装

需要 Python 3.x。建议将此工具安装在虚拟环境中。

$ pip install -U dl_coursera
$ dl_coursera --version

如何

1. 获取cookies.txt文件

   登录Coursera，然后使用浏览器扩展将 cookie 导出为cookies.txt。cookies.txt将在大约两周后过期，因此您无需如此频繁地执行此操作。

   对于Chrome，您可以使用cookies.txt扩展。

   

   对于Firefox，您可以使用Export Cookies扩展。

   

2. 注册

   导航到您要下载的课程/专业的主页，您可以在地址栏看到它的slug。注册它。

   

3. 下载

   $ dl_coursera --help
   usage: dl_coursera_run.py [-h] [--version] [--cookies COOKIES] --slug SLUG
                             [--isSpec] [--n-worker {1,2,3,4,5}]

                             {builtin,curl,aria2,aria2-rpc,uget,dummy}

                             [--aria2-rpc-secret ARIA2_RPC_SECRET]
   
   A simple, fast, and reliable Coursera crawling & downloading tool
   
   optional arguments:
     -h, --help            show this help message and exit
     --version             show program's version number and exit
     --cookies COOKIES     path of the `cookies.txt`
     --slug SLUG           slug of a course or a specializtion (with @--isSpec)
     --isSpec              indicate that @--slug is slug of a specialization
     --n-worker {1,2,3,4,5}
                           the number of threads used to crawl webpages. Default:
                           3
     --outdir OUTDIR       the directory to save files to. Default: `.'
     --how {builtin,curl,aria2,aria2-rpc,uget,dummy}
                           how to download files. builtin (NOT recommonded): use
                           the builtin downloader. curl: invoke `curl` or
                           generate an "input file" for it (with @--generate-
                           input-file). aria2: invoke `aria2c` or generate an
                           "input file" for it (with @--generate-input-file).
                           aria2-rpc (HIGHLY recommonded): add downloading tasks
                           to aria2 through its XML-RPC interface. uget
                           (recommonded): add downloading tasks to the uGet
                           Download Manager
     --generate-input-file
                           when @--how is curl/aria2, indicate that to generate
                           an "input file" for that tool, rather than to invoke
                           it
     --aria2-rpc-url ARIA2_RPC_URL
                           url of the aria2 XML-RPC interface. Default:
                           `http://localhost:6800/rpc'
     --aria2-rpc-secret ARIA2_RPC_SECRET
                           authorization token of the aria2 XML-RPC interface
   
   If the command succeeds, you shall see `Done :-)`. If some UNEXPECTED errors
   occur, try decreasing the value of @--n-worker and/or removing the directory
   @--outdir. For more information, visit `https://github.com/feng-lei/dl_coursera`.
   

   # download the course, of which slug is "mathematical-thinking"
   # saving files to the directory "mt"
   # using the "built-in" downloader
   $ dl_coursera --cookies path/to/cookies.txt --slug mathematical-thinking --outdir mt --how builtin
   

   # download the specialization, of which slug is "algorithms"
   # saving files to the directory "alg"

例子

使用“内置”下载器

$ dl_coursera --cookies path/to/cookies.txt --slug mathematical-thinking --outdir mt --how builtin

使用“curl”下载器

# make sure curl (https://curl.haxx.se/download.html) is installed and in PATH
$ curl --version

“curl”下载器可以以两种不同的方式使用：调用curl，或为curl.

调用curl

$ dl_coursera --cookies path/to/cookies.txt --slug mathematical-thinking --outdir mt --how curl

生成一个输入文件curl

$ dl_coursera --cookies path/to/cookies.txt --slug mathematical-thinking --outdir mt --how curl --generate-input-file
$ curl --config mt/mathematical-thinking.download.curl_input_file.txt

使用“aria2”下载器

# make sure aria2 (https://aria2.github.io) is installed and in PATH
$ aria2c --version

“aria2”下载器可以以两种不同的方式使用：调用aria2c，或为aria2c.

调用aria2c

$ dl_coursera --cookies path/to/cookies.txt --slug mathematical-thinking --outdir mt --how aria2

生成一个输入文件aria2c

$ dl_coursera --cookies path/to/cookies.txt --slug mathematical-thinking --outdir mt --how aria2 --generate-input-file
$ aria2c --input-file mt/mathematical-thinking.download.aria2_input_file.txt

使用“aria2-rpc”下载器

# make sure aria2 (https://aria2.github.io) is installed and in PATH
$ aria2c --version

# start aria2 with its XML-RPC interface enabled
$ aria2c --enable-rpc

$ dl_coursera --cookies path/to/cookies.txt --slug mathematical-thinking --outdir mt --how aria2-rpc

强烈推荐使用像 webui -aria2这样的 aria2 GUI 。

使用“uget”下载器

# make sure uGet (https://sourceforge.net/projects/urlget/files/) is installed and in PATH

## on Windows
$ uget --version | more

## on Linux
$ uget-gtk --version

# start uGet

## on Windows
$ uget

## on Linux
$ uget-gtk &

$ dl_coursera --cookies path/to/cookies.txt --slug mathematical-thinking --outdir mt --how uget
