<p>背景：</p>
<p>Course Crawler是一个开源项目，这个可以爬取一些学习视频，比如我最近在看Java，就爬了<br>
一些Java的学习视频；<br><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THprd015ODBZelprWWpkak56QXdZMlkyTlRFeU9XRTRNVEl6TW1JNU9USTFNekJsTnk1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"><br>
这世上没有无缘无故的爱憎。。。我写这个文档的原因是…之前把这个爬虫工具介绍给了一个<br>
小伙伴，我说随便搞两个小时你就会了。</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpZeUx6Y3hNMlkwWkRReVpUa3hPV014WlRKaFptSXhabVk1TW1FM05HSTBNelZsTG5CdVp3PT0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>结果朋友这样回答我</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpVek5TOHpaalpqT1dJeU1tVTNNelU1WlRNd05UUTNZVGRsTVdaaFptWXlOalZqTnk1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>

<p>一： 进入正题前，让我们扯点别的。。。</p>
<p>磨难不会让人成长，但是对磨难的反思会；我还依稀记得我大学我C语言考了65分，我感到很<br>
羞愧，因为是院长教的，但我学习的那么差；将心比心，我毕竟工作了一年半了，看这个捣鼓起来比较快，要是一个啥也不会的小白你让人家咋整（比如我那个朋友，看到不要打我…）</p>
<p>在我刚毕业的时候，要是有人给我推荐一个网站，然后BlaBla说两个小时就能学会，我一定打爆他的狗头，问问他说的是人话吗，我连第一步都不会啊（这么坚强的我为啥哭了）。<br><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THprd0wySTFOelV6WVdJeU0yRTVZMlpqT0dOa09EQTFaRFZpWmpSa05EQmhPVE15TG5CdVp3PT0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>二：</p>
<p>那我们进入正题呗… 先安装Python</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpZd05TODNaakUzTXpKaE9EUXlNemhtTkRSaE0yRXpZemt3TXpSbE1USmtPV1UxTlM1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"><br><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpFMk1TOWxOV1ZoTWpCa1lqZGxZVFUxWXpRM01ESXhOVEJqT1RJd1pUUTRaR1ZrTVM1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpNeE55ODVZV0UzTURRM05tUTNaVGRtWVRJelpEUm1Zemc0TVRWak1EZGhZakJqTlM1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"><br>
弹出一系列的Python版本，我们就用最新的吧3.8.1的；<br><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpjNUx6UTRaRFZpTjJFMVpURmxNekV5TmpjMk5HSmxaVE0wWldVME4yRTNOV0ptTG5CdVp3PT0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"><br>
在D盘新建一个文件夹：</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpnMk1DOWxPVFU0TnpNMFlUTmlOVFZsT1Rjd1ptWTNaREJoT0RCbFptUXpZemMxTkM1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>然后双击下载好的安装包安装：<br><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THprM0wyRXdOemhsT0dOaVlUUXdaRFJsWmpRd1lqZGpOamRoTlRBek9UVXhOVGc1TG5CdVp3PT0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>我要改下安装路径：</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpFNU9TODNPRFJrTkdVM01XVmtOR1JsTTJZeVpETXhOR0ZqWm1ZM01qZGhOemt4Tnk1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>注意这个pip后面会用到，继续点击Next，所有都默认好了…反正又不是用Python搞开发…</p>

<p>OK，Python安装成功了，我们close掉界面。</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpneU15ODBNbVkwTnpWaVpUTTJaak0xWkRRMVlXVTVNVEEyWVdKbFl6WTNPVEUxTnk1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>三：</p>
<p>安装这个爬虫工具需要的运行库， (这就是我那个朋友说的第一步就不会的地方…）</p>
<p>我们先找到pip的位置：（上面我自定义安装的）<br>
D:\Python\Scripts</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpjMk1DODRZMlpoWldGaE0yUXpaalk0TlRFeVl6ZGtZV1ZoTmpWall6a3pOekl6TUM1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>处于上面这个界面，在空白区域同时按住键盘上的shirft以及鼠标右键打开命令行窗口(WIN7)；</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpJME1DODNOVEUwWmpBMU5qUmtNV0U0TkdRMFpURTJOR0UwTTJNME5ESXpaalpqTUM1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>如果是win10，它使用Powershell窗口替代了命令行；<br><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpFd09DOW1PR0prTkRNM01ESmhabVJpT0RjMU5EWXpPVEJqTlRreU5XUTFaVEUwTkM1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>OK，接下来我们输入命令：</p>
<p>pip install requests BeautifulSoup4 lxml</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpRMU1pOWtaRFF5WWpObVpqVTFaVFExT0dNd09UVTVaR0l3TkRSak9ERTVNRFExTkM1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>卧槽居然有报错，那我们按照它的提示再整下(win7就不会报错，只是格式不同）：</p>
<p>.\pip install requests BeautifulSoup4 lxml</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpneU9TOWpaV1l5TURZeU16bGhNbVpoTVdRM1kyWTJNRFJsTWpGbE9HSTBOalZrWkM1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>稳，安装成功了</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpFNU9TODJZemRpTXpkaFl6VTJZamN3TUdFek1HRm1PR0psWkRobE1qVTNaVGMwTnk1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>四：</p>
<p>现在东西都准备好了，我们去github下载这个爬虫工具本身，感谢作者；</p>
<p>https://github.com/Foair/course-crawler</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpZeE5TODRaVGxrWVdWaE1qaGlabVV5TjJRMlpUUTNOak5sTUdFNVpEWXdaVGxoWmk1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>我们在浏览器输入地址，然后下载</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpJek15OWtPVGxoT0RabU9HRTFaVGswTldNMFpHVTJNalExWmpGbFpHVTNZek0xT1M1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>把压缩包放到Python同级目录：</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpnNU1pODVZbUkxWTJJNFpUYzJaV1kwT0RobU5XWmxZV0poTURRek56bGhPVGczWXk1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>进入： D:\Python\course-crawler-master</p>
<p>还是和刚才一样，用shift+鼠标右键打开Powershell</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpjMk15OWxaVGxpTldSbFpESTVaRFZpT1dGbU4yWXdaREl6TjJFNVptSm1aakZtTXk1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>五： 我们找下资源地址，比如我想看浙大陈越教授的数据结构：</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpRd01TOWxZVFE0TmpRNE5qZGpNRFl4TmpJeVpEUXhZVE15WXpGa1pETmhZelU1T1M1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>这个还没开始，我们找下之前的，第10次的；<br><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpJNE5DODVOMkkwT0dKa05tTmhaalJqTkdVMU0yTTRPVFZoWmpJM1l6VXpZamt4WXk1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>必须处于当前界面，把网址拷贝：</p>
<p>win7输入： mooc.py https://www.icourse163.org/course/ZJU-93001?tid=1207006212</p>
<p>win10输入： .\mooc.py https://www.icourse163.org/course/ZJU-93001?tid=1207006212</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpVMU5pODVZbVptWVdRNVpEQmtZVE01TldFMk9HWmpZMkl4T0RVMFpETTNNVGhtWXk1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>各种课件、pdf、视频源地址都爬好了：</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpnME5pOHlZekZrT0RWaU5XSmhNVFUxT0dRNE1UazBPV1l4WmpCaU9HUmxOR0kwWlM1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"><br>
进入Videos文件夹，然后可以用下载工具把视频下下来（比如用迅雷）之后用批处理文件，Rename.bat批处理文件，就能把文件名显示正常了。</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpRM015OWpNVFpsTXpBMk5tTTFOREkxWTJaaVpqZ3dOMkpqWWpnNE1XRTJNakV6TVM1d2JtYz0=" alt="从零开始教你用Course Crawler爬虫工具" title="从零开始教你用Course Crawler爬虫工具"></p>
<p>之后大家可以用Potplayer播放器播放视频文件（强烈推荐，没有广告，这个是音视频开发常用的软件）</p>
<p>请大家不要把视频用于商业用途，如果要表达感谢，请给作者加个star.</p>
<p>希望对大家有帮助，努力学习感兴趣的课程，并且坚持下去，共勉！</p>
<p>OVER！</p>
