# Compile
```bash
git clone https://github.com/fumiama/simple-http-server.git
cd simple-http-server
mkdir build
cd build

# Command line usage

simple-http-server [-d] [-p ] [-r ] [-u ]
```
- **-d**: run as daemon.
- **-p**: if not set, choose a random one.
- **-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
```c
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.

And its realization is here:
