libuhttpd

license PRs Welcome Issue Welcome Release Version

一个轻量的全异步的HTTP服务器C库基于libubox,参考了uhttpd

请保持关注以获取最新的项目动态

特性

  • Action - 通过调用映射到特定路径的已注册C函数来处理请求。
  • 轻量、全异步
  • 使用libubox作为其事件后端
  • 支持HTTPS - OpenSSL, mbedtls 和 CyaSSl(wolfssl)
  • 可伸缩 - 你可以非常方便的扩展你的应用程序使之具备HTTP/HTTPS服务
  • 代码结构简洁通俗易懂,亦适合学习
  • Lua模板 - 嵌入LUA代码到HTML中就像嵌入PHP到HTML中一样

计划支持

  • Lua API - 使用Lua编程

依赖

配置

查看支持哪些配置选项

~/libuhttpd/$ mkdir build && cd build
~/libuhttpd/build$ cmake .. -L
~/libuhttpd/build$ cmake .. -LH

编译和安装

~/libuhttpd/build$ make && sudo make install

运行示例程序

运行

~/libuhttpd/build$ ./example/helloworld

然后使用命令curl或者浏览器进行测试

$ curl -k 'https://127.0.0.1:8000/hello?name=test' -d '{"name":"libuhttpd"}' -v

如何在OpenWRT中使用

Add new feed into "feeds.conf.default":

src-git libuhttpd https://github.com/zhaojh329/libuhttpd-feed.git

for chaos_calmer(15.05)

src-git libuhttpd https://github.com/zhaojh329/libuhttpd-feed.git;for-15.05

Install libuhttpd packages:

./scripts/feeds update libuhttpd
./scripts/feeds install -a -p libuhttpd

Select package libuhttpd in menuconfig and compile new image.
