-# BiliNovel Downloader
+# Bilinovel Downloader
 
-这是一个用于下载和生成轻小说 EPUB 电子书的工具。
+这是一个用于从 Bilinovel 下载和生成轻小说 EPUB 电子书的工具。
+生成的 EPUB 文件完全符合 EPUB 标准，可以在 Calibre 检查中无错误通过。
 
-## 功能特点
+## 使用示例
 
-- 支持下载轻小说并转换为标准 EPUB 格式
-- 自动处理图片和文本内容
-- 生成符合 EPUB 3.0 规范的电子书文件
-- 支持多章节内容的组织和管理
-- 保留原有插图和排版格式
+1. 下载整本 `https://www.bilinovel.com/novel/2388.html`
 
-## 使用说明
+   ```bash
+   bilinovel-downloader download -n 2388
+   ```
 
-1. 确保系统环境满足要求
-2. 运行下载器获取小说内容
-3. 程序会自动处理并生成标准格式的 EPUB 文件
-4. 生成的电子书文件可以在任何支持 EPUB 3.0 的阅读器中打开
+2. 下载单卷 `https://www.bilinovel.com/novel/2388/vol_84522.html`
 
-## 注意事项
+   ```bash
+   bilinovel-downloader download -n 2388 -v 84522
+   ```
 
-- 生成的 EPUB 文件严格遵循 EPUB 3.0 规范
-- 建议使用支持 EPUB 3.0 的阅读器以获得最佳阅读体验
-- 请遵守相关法律法规，合理使用下载的内容
+3. 对自动生成的 epub 格式不满意可以自行修改后使用命令打包
+
+   ```bash
+   bilinovel-downloader pack -d <目录路径>
+   ```
+
+## 算法分析
+
+目前程序使用 playwright 进行爬取来规避 bilinovel 的反爬（诱饵段落和段落重排）策略。  
+但是依然对 bilinovel 的算法进行了简单的分析，具体可以参考[代码](./test/no_playwright_method_test.go)，这个代码目前是可行的，但如果 bilinovel 频繁更改初始化种子的计算方式或算法的实现，会让排序方法失效，这也是为什么目前程序使用 playwright。

+<br>
+<p>一位少女恭敬地弯腰向走进木质大门的绅士致意。</p>
+<p>少女穿着一件做工精致的黑色连衣裙，上面系着花边以及刺绣、并不华丽的纯白围裙，梳成编辫的黑发上系着可爱的蕾丝头带。</p>
+<br>
+<p>无论从哪个角度看，都是迎接主人归来的女仆样子。</p>
+<br>
+<p>「啊，我回来了」</p>
+<br>
+<p>绅士把帽子和大衣交给恭敬地弯腰的女仆，用温柔的语气回答。</p>
+<br>
+<p>「我马上为您准备茶水。请问您想要哪一款？」</p>
+<p>「那么，我想要一杯伯爵红茶。」</p>
+<p>「要加牛奶之类的吗？」</p>
+<p>「不，不用了。」</p>
+<p>「遵命。茶点要什么呢？」</p>
+<p>「嗯，就交给你吧。拜托了？」</p>
+<br>
+<p>对着绅士的话语，身为女仆的少女露出了轻柔的微笑。她可能只有十五、六岁吧。脸上还带着稚气，但未来值得期待，可爱又温柔的容貌。</p>
+<br>
+<p>「请交给我，我会准备合您口味的茶点。」</p>
+<p>「啊，拜托了。」</p>
+<br>
+<p>女仆少女将帽子和大衣挂在衣架上，然后引导绅士到餐桌。</p>
+<br>
+<p>＊＊＊＊＊＊＊＊＊＊</p>
+<br>
+<p>「那么，我要出门了。」</p>
+<p>「好的，老爷」</p>
+<p>「下次回来时，如果能再让妳接待就好了……」</p>
+<br>
+<p>「下次她想要带朋友在露台喝茶，也希望你能照顾他们。」</p>
+<br>
+<p>轻轻敲门后，听到「请进」的回答，少女走进了房间行礼。</p>
+<p>一个少女嘟囔着。那是一位身穿简素蓝色连衣裙的少女。闪闪发光的银色头发留到了胸口。有着神秘的琉璃色瞳孔的美丽可爱少女站在母亲身旁。</p>
+<p>送走绅士后，女仆少女前往总管的房间。</p>
+<br>
+<p>「欸，对我不需要用这种说话方式吧？……律子酱。」</p>
+<p>薪水丰厚的兼职让她顺利存下了留学费用，留学之日即将到来。</p>
+<p>「拜托了！」</p>
+<br>
+<p>女仆少女律子满脸笑容地回答。</p>
+<br>
+<p>「话说回来，律子酱。上次来的坂上夫人很喜欢你呢。上次寄来的邮件里相当称赞。她说下次还打算指名。」</p>
+<br>
+<p>「失礼了，Miss 阿曼达。关于刚才离开宅邸的老爷报告……」</p>
+<br>
+<p>被叫做律子的女仆少女张开眼，刚才还散发着女仆气息的模样一下子变回稚气十足的少女，她嘟起嘴说道。</p>
+<br>
+<p>「这样很好啊！」</p>
+<p>女仆少女律子满脸笑容地回答。</p>
+<p>对担忧这一点的父母来说，当时的律子的情况无疑让人开心。</p>
+<br>
+<p>因此，父母并未反对女儿出人意表的宣言。</p>
+<br>
+<p>标题叫『深窗的公主的悲恋』。</p>
+<p>优雅的动作，没有任何不自然的温柔笑容。仿佛是女仆典范一般的少女。看着她的身影，总管阿曼达皱了皱眉。不，这是因为……</p>
+<p>「怎么了？瑟蕾丝蒂？」</p>
+<br>
+<p>「啊，拜托了。那么……」</p>
+<p>「一路顺风，老爷。」</p>
+<p>「遵命。我会将您的意愿转达给<ruby>女仆总管<rp>(</rp><rt>家政妇</rt><rp>)</rp></ruby>。」</p>
+<p>（公主身后的女仆们是多么的优秀啊！）</p>
+<br>
+<p>「你真的很喜欢做这种工作呢。这样一来就得早晨开始准备了。下次我会去问问她们的希望。」</p>
+<br>
+<p>这部电影以旧时英国贵族的故事为题材。描述了一位在呵护下长大的贵族千金，偶然认识一位平民青年，并陷入爱河的故事。最后，因为身份差异，两人自尽，悲剧结局。</p>
+<br>
+<p>父母看着律子的身影，感到非常开心。</p>
+<p>女仆们使出各种手段帮助她与男子相会。</p>
+<p>在女仆的影响下，律子对各种事物产生了兴趣，玩耍、笑声、学习，成长为一个非常优秀的女儿。自从遇见女仆以来，好奇心无止境，虽然年龄和性格相比有些幼稚，但对父母来说，女仆这个存在也是让人有好感的。</p>
+<br>
+<p>她的名字是瑞波律子，二十岁，现在是大学二年级的学生。</p>
+<br>
+<p>「我讨厌那个名字啊。明明是日本人，却叫阿曼达……」 <span style="color: rgb(61，142，185);">（＊亚万田日语念成阿曼达）</span></p>
+<br>
+<p>当然，因为主角是英国贵族千金，所以电影里并没有描绘女仆们努力的场景。但正因为如此，律子对在幕后默默支持的女仆们十分感动。</p>
+<p>「……本来应该是这样的啊。」</p>
+<p>来这家女仆咖啡厅的客人并不仅仅是男性。这家店的男女客人比例几乎是一比一。</p>
+<br>
+<p>会员制高级女仆咖啡厅『<ruby>贵族的日常<rp>(</rp><rt>Noble's One Day</rt><rp>)</rp></ruby>』。</p>
+<br>
+<p>生活了六年，律子慢慢的成长，但她却不对事物报持热情。喜欢的玩具和书籍都没有，看电视也不会表现出太多兴趣。</p>
+<br>
+<p>「拜托了！」</p>
+<br>
+<p>那是瑞波律子还不懂爱情的六岁春天的事……先不管给一个六岁小孩看悲恋电影的问题。</p>
+<p>是被称为女仆总管的女性，亚万田凪沙创建的店。</p>
+<br>
+<p>「我在大学毕业后，想在英国成为真正的女仆！」</p>
+<br>
+<p>「好的，请放心交给我！」</p>
+<br>
+<p>「欸，真的吗!?  就是上周来过的那位温柔的女士吗？」</p>
+<p>男士需穿着西装，女士需穿着礼服，这是服装规定。特别为女性客人提供服装租赁服务，因此女性客人可以享受穿着平时难得一穿的贵族少女或贵妇风格的洋装，扮演女主人的角色。</p>
+<br>
+<p>虽然二十岁了，律子的脸庞略显年幼，她是这家店最受欢迎的女仆。</p>
+<br>
+<p>看过这部电影的观众都为两人的悲恋流泪，感动不已。</p>
+<br>
+<p>从那时起，律子就迷上了女仆。她向父母说明了女仆是多么伟大的存在，并激动地宣布有一天她也会成为女仆。</p>
+<p>完全预约制，到店时会有指名的女仆迎接。此时店员会完全扮演女仆角色，客人不是客人身份，而是扮演女仆的主人，享受其中。</p>
+<br>
+<p>一切都是顺风顺水。距离成为女仆只剩下最后一步！</p>
+<br>
+<p>美丽的行礼后，少女向绅士回以温柔的微笑。绅士推开门离开了。</p>
+<br>
+<p>律子的梦想是成为女仆。原因非常简单，那是因为她小时候看过的一部电影。</p>
+<br>
+<p>在父母的支持下，律子在大学学习外语、历史、文学、礼仪等，以成为女仆为目标，在本格派女仆咖啡厅进行女仆训练的日常。</p>
+<br>
+<p>「那么，我也可以帮忙准备衣服和化妆吗？」</p>
+<p>「讨厌！再让我扮一下女仆也没关系嘛，亚万田小姐！」</p>
+<br>
+<p>绅士略显羞涩地说着，女仆的少女露出了微笑回答。</p>
+<p>然而，律子却对另一方面感动不已。</p>
+<br>
+<br>
+<br>
+<br>
+<br>
+<p>支付是预付制，店内不谈金钱。没有菜单，女仆会自然接受点单。客人只需要享受那片刻的主人时光即可。</p>
+<p>女主角的贵族千金拥有很温柔的人格，所以她的女仆们也非常喜爱她。</p>
+<br>
+<p>为了筹集到英国留学的资金，进入大学的律子开始寻找兼职工作。她认为对未来有帮助的工作是最好的，于是找到了这家女仆咖啡厅。</p><div class="cgo"><script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-8799828951681010"
