这个用Python写的开源爬虫网站 让你秒搜所有豆瓣好书 ！

程序员在提升自己的道路，大多还是会选择阅读编程书籍这一途径，但找到一本好书就没那么容易了。

通过查看各大销售网站的销量数据和评价，以及豆瓣评分和评价人数，可以帮助我们更快的挖掘出经典的计算机书籍，还有那些被人们忽视的好书。

最近猿哥在GitHub上发现了一个网站，是中国科学院自动化研究所的一大神（lanbing510）用Python写的一个爬虫，他在16年的时候就爬下了豆瓣所有的读书数据并做了个WebApp接口方来挖掘查找和阅读好书。怪我知道的太晚

Python学习交流群：1004391443，这里有资源共享，技术解答，还有小编从最基础的Python资料到项目实战的学习资料都有整理，希望能帮助你更了解python，学习python

后来lanbing510再次爬了一遍豆瓣读书的数据，总共更新了3232088本图书信息，共2138386KB，并将其开源

为什么说它很好用呢？猿哥演示一遍你就知道了：

<tt-image data-tteditor-tag="tteditorTag" contenteditable="false" class="syl1558940808166 ql-align-center" data-render-status="finished" data-syl-blot="image" style="box-sizing: border-box; cursor: text; text-align: left; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "WenQuanYi Micro Hei", "Helvetica Neue", Arial, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: block;"> image

<input class="pgc-img-caption-ipt" placeholder="图片描述(最多50字)" value="" style="box-sizing: border-box; outline: 0px; color: rgb(102, 102, 102); position: absolute; left: 187.5px; transform: translateX(-50%); padding: 6px 7px; max-width: 100%; width: 375px; text-align: center; cursor: text; font-size: 12px; line-height: 1.5; background-color: rgb(255, 255, 255); background-image: none; border: 0px solid rgb(217, 217, 217); border-radius: 4px; transition: all 0.2s cubic-bezier(0.645, 0.045, 0.355, 1) 0s;"></tt-image>

可以看出这网站的界面非常简洁，没有花里花哨的内容，只有干货，你可以直接通过关键字、分数、和评价人数这三个选项进行搜索，比如我们可以搜索关键字：编程；分数：9.0；评价人数：100人以上

查找结果的显示方式有按照分数排序和人数排序两种，按照分数排序的截图如下：

<tt-image data-tteditor-tag="tteditorTag" contenteditable="false" class="syl1558940808169 ql-align-center" data-render-status="finished" data-syl-blot="image" style="box-sizing: border-box; cursor: text; text-align: left; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "WenQuanYi Micro Hei", "Helvetica Neue", Arial, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: block;"> image

<input class="pgc-img-caption-ipt" placeholder="图片描述(最多50字)" value="" style="box-sizing: border-box; outline: 0px; color: rgb(102, 102, 102); position: absolute; left: 187.5px; transform: translateX(-50%); padding: 6px 7px; max-width: 100%; width: 375px; text-align: center; cursor: text; font-size: 12px; line-height: 1.5; background-color: rgb(255, 255, 255); background-image: none; border: 0px solid rgb(217, 217, 217); border-radius: 4px; transition: all 0.2s cubic-bezier(0.645, 0.045, 0.355, 1) 0s;"></tt-image>

按照评价人数排序的截图如下：

<tt-image data-tteditor-tag="tteditorTag" contenteditable="false" class="syl1558940808172 ql-align-center" data-render-status="finished" data-syl-blot="image" style="box-sizing: border-box; cursor: text; text-align: left; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "WenQuanYi Micro Hei", "Helvetica Neue", Arial, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: block;"> image

<input class="pgc-img-caption-ipt" placeholder="图片描述(最多50字)" value="" style="box-sizing: border-box; outline: 0px; color: rgb(102, 102, 102); position: absolute; left: 187.5px; transform: translateX(-50%); padding: 6px 7px; max-width: 100%; width: 375px; text-align: center; cursor: text; font-size: 12px; line-height: 1.5; background-color: rgb(255, 255, 255); background-image: none; border: 0px solid rgb(217, 217, 217); border-radius: 4px; transition: all 0.2s cubic-bezier(0.645, 0.045, 0.355, 1) 0s;"></tt-image>

除了以上演示的操作，这个网站并实现了以下功能：

• 可以爬下豆瓣读书标签下的所有图书
• 按评分排名依次存储
• 存储到Excel中，可方便大家筛选搜罗，比如筛选评价人数>1000的高分书籍；可依据不同的主题存储到Excel不同的Sheet
• 采用User Agent伪装为浏览器进行爬取，并加入随机延时来更好的模仿浏览器行为，避免爬虫被封

也就是说你不仅可以在网站上搜索，还能通过下载各类目下的Excel书单文件，直接在Excel中搜索

<tt-image data-tteditor-tag="tteditorTag" contenteditable="false" class="syl1558940808177 ql-align-center" data-render-status="finished" data-syl-blot="image" style="box-sizing: border-box; cursor: text; text-align: left; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "WenQuanYi Micro Hei", "Helvetica Neue", Arial, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: block;"> image

<input class="pgc-img-caption-ipt" placeholder="图片描述(最多50字)" value="" style="box-sizing: border-box; outline: 0px; color: rgb(102, 102, 102); position: absolute; left: 187.5px; transform: translateX(-50%); padding: 6px 7px; max-width: 100%; width: 375px; text-align: center; cursor: text; font-size: 12px; line-height: 1.5; background-color: rgb(255, 255, 255); background-image: none; border: 0px solid rgb(217, 217, 217); border-radius: 4px; transition: all 0.2s cubic-bezier(0.645, 0.045, 0.355, 1) 0s;"></tt-image>

效果截图如下：
