+nHentai is a CLI tool for downloading doujinshi from [nhentai.net](http://nhentai.net).
-由于 [http://nhentai.net](http://nhentai.net) 下载下来的种子速度很慢，而且官方也提供在线观看本子的功能，所以可以利用本脚本下载本子。

-下载指定 id 列表的本子：
+```bash
-```bash
+nhentai --id=123855,123866
-nhentai --id=123855,123866
+```
-```
+
-
+Search a keyword and download the first page:
-下载某关键词第一页的本子：
+```bash
-```bash
+nhentai --search="tomori" --page=1 --download
-nhentai --search="tomori" --page=1 --download
+```
-```
+
-
+Download your favourite doujinshi (login required):
-下载用户 favorites 内容：
+```bash
-```bash
+nhentai --login "username:password" --download
-nhentai --login "username:password" --download
+```
-```
+
-
+Download by tag name:
-### Options
+```bash
-
+nhentai --tag lolicon --download
-`-t, --thread`：指定下载的线程数，最多为 10 线程。  
+```
-`--path`：指定下载文件的输出路径，默认为当前目录。  
+
-`--timeout`：指定下载图片的超时时间，默认为 30 秒。  
+### Options
-`--proxy`：指定下载的代理，例如: http://127.0.0.1:8080/
+
-`--login`：nhentai 账号的“用户名:密码”组合
++ `-t, --thread`: Download threads, max: 10  
-
++ `--output`:Output dir of saving doujinshi  
-### nHentai Mirror
++ `--tag`:Download by tag name  
-如果想用自建镜像下载 nhentai 的本子，需要搭建 nhentai.net 和 i.nhentai.net 的反向代理。  
++ `--timeout`: Timeout of downloading each image   
-例如用 h.loli.club 来做反向代理的话，需要 h.loli.club 反代 nhentai.net，i.h.loli.club 反带 i.nhentai.net。  
++ `--proxy`: Use proxy, example: http://127.0.0.1:8080/  
-然后利用环境变量来下载：  
++ `--login`: username:password pair of your nhentai account  
-
++ `--nohtml`: Do not generate HTML  
-```bash
++ `--cbz`: Generate Comic Book CBZ File  
-NHENTAI=http://h.loli.club nhentai --id 123456
+
-```
+### nHentai Mirror
-
+If you want to use a mirror, you should set up a reverse proxy of `nhentai.net` and `i.nhentai.net`.
-![](./images/search.png)  
+For example:
-![](./images/download.png)  
+
-![](./images/viewer.png)  
+    i.h.loli.club -> i.nhentai.net
-
+    h.loli.club -> nhentai.net
-### License  
+
-MIT
+Set `NHENTAI` env var to your nhentai mirror.
-
+```bash
-### あなたも変態
