git clone https://github.com/fumiama/simple-http-server.git
cd simple-http-server
mkdir build
cd build
cmake ..
make
make install

simple-http-server [-d] [-p <port>] [-r <rootdir>] [-u <uid>]

• -d: run as daemon.
• -p: if not set, choose a random one.
• -r: http root dir.
• -u: run as this uid.

When you put an executable file into the web path, the server will call execl to run it while passing 3 parameters as below

argv[0] = path;   //Path of the executable file
argv[1] = method; //request method (GET/POST)
argv[2] = query_string;   //the query string, like "a=1&b=2&c=3"

The server will read a 4 bytes unsigned integer from pipe, indicating the length of the remaining content. Then it will send length bytes of data to the client directly with nothing being decorated, which means that you need to assemble the HTTP header by yourself.

Here is a CGI example CMoe-Counter
