Command line usage

simple-http-server [-d] [-h] [-n host.name.com:port] [-p <port|unix socket path>] [-q 16] [-r <rootdir>] [-u <uid>]
  • -d: run as daemon.
  • -h: display this help.
  • -n: check hostname and port.
  • -p: if not set, we will choose a random port.
  • -q: listen queue length (defalut is 16).
  • -r: http root dir.
  • -u: run as this uid.

CGI usage

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

And its realization is here:
