Features

• use libev as its event backend
• tiny and fast
• SSL support: Optional OpenSSL and CyaSSl(wolfssl)
• flexible and you can easily extend your application to have HTTP/HTTPS services

Why use libev as its backend?

libev tries to do one thing only (POSIX event library), and this in the most efficient way possible. Libevent tries to give you the full solution (event lib, non-blocking I/O library, http server, DNS client).

libev tries to follow the UNIX toolbox philosophy of doing one thing only, as good as possible.

How to Build

Install dependency Tools and Libraries

Ubuntu

~$ sudo apt install gcc cmake libev-dev libhttp-parser-dev libssl-dev libwolfssl-dev

CentOS

~$ sudo yum install gcc cmake libev-devel http-parser-devel openssl-devel

Clone the repository

~$ git clone https://github.com/zhaojh329/libuhttp.git
~$ cd libuhttp

Create the build directory

~/libuhttp$ mkdir build
~/libuhttp$ cd build

Configure

See which configuration are supported

~/libuhttp/build$ cmake .. -L
~/libuhttp/build$ cmake .. -LH

Default configure: automatically select the SSL library as its SSL backend(If there is a SSL library available).

~/libuhttp/build$ cmake ..

Disable SSl support

~/libuhttp/build$ cmake .. -DUHTTP_DISABLE_SSL=1

Explicit use OpenSSL as its SSL backend

~/libuhttp/build$ cmake .. -DUHTTP_USE_OPENSSL=1

Explicit use CyaSSl(wolfssl) as its SSL backend

~/libuhttp/build$ cmake .. -DUHTTP_USE_CYASSL=1

Turn on debug

~/libuhttp/build$ cmake .. -DUHTTP_DEBUG=1

Build and install libuhttp

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

Run the Example

First generate the SSL certificate file

~/libuhttp/build$ cd ..
~/libuhttp$ ./gen_cert.sh

Run

~/libuhttp$ ./build/example/helloworld

Then use the command curl or browser to access https://127.0.0.1:8000/test

$ curl -k https://127.0.0.1:8000/test -v
