今天小弟问我用过NanoHTTPD没有,想在Android上面使用它。百度了下,发现是Apache下面的一个开源项目。于是好奇的看了下,根据介绍说是一个小巧轻型的WEB服务器。它小到什么程度呢,小到源码只有一个JAVA文件,给人一种87V5的感觉。
通过继承这个源码类并实现serve接口,就可以完成web服务器的基本功能。
如果你的项目需要一个简单的静态web服务,相信它是一个不错的选择,当然可以发挥你的聪明才智使用到其它地方,比如移动设备、智能设备等。
如果你想快速搭建起来使用一个简单的DEMO,那么它的源码里 SimpleWebServer 肯定会让你惊喜的。
以下是唯一的一个源码文件的描述。虽然是英文,但是它还是很简单的~~

SimpleWebServer 这个例子是有一个小小的问题的。
采用POST方式不能获取参数值,也就是通过 session.getParms 获取不相应Form表单中的参数值。原因是因为serve 这个覆盖实现没有对POST上来的参数进行解析,当然如果POST上来的文件更没有解析,更拿不到上传的文件。通过查看父类里实现,可以找到解决方案。
那么子类(SimpleWebServer )只需要做如下修改即可
