# Serwer
## Standalone webserver written in C99
### What is this shit?
Well, it's standalone webserver written entirely in C99 (no libs required).
### Why would someone need this?
I've no idea. But I'm going to use this for my next project.
### Why is it's name to weird?
Because W for web... Get it? ... Well next time I'll ask you for a catchy name, smartypants.
### Is this ... thing ... even finished?
No. There are many functions missing and the code needs some revision (and comments I suppose).
There is a working mode though (see [the main file](main.c) for an example).
If you want to help me with this project, feel free to fork and submit-pull requests.
I also appreciate opinions, suggestions and complaints.
### I don't get it. Is this a webserver for a lib for webservers?
Both, I guess. Although as I'm thinking about it, it might actually be more of a library...
### Okay...? So, how can I use this thing?
See [the main file](main.c).
Basically you need at least one handler.
```c
/**
* @param method contains the method-type (see method_t); can be stringified with const char* ws_strm(method_t)
* @param host the hostname (e.g. "localhost:8080" or "www.google.com")
* @param path the requested URI
* @param requestHeaders the headers of the request (see headers_t)
* @param responseHeaders well... guess. (Hint: You can modify these.)
* @param request "file" stream of the request (can be read with e.g. fscanf(2))
* @param respinse "file" stream for the response (can be written with w.g. fprintf(2))
*/
int not_found(method_t method, const char* host, const char* path, headers_t requestHeaders,
headers_t* responseHeaders, stream_t request, stream_t response) {
// The definition of this function is defined as handler_t (don't confuse with handle_t) in /webserver.h.
// You can write a response like this.
fprintf(response, "\n");
fprintf(response, "Not Found");
fprintf(response, "404 - File Not Found
");
fprintf(response, "The requested file (%s) was not found on this server.
", path);
fprintf(response, "");
return 404; // This is the HTTP status code by the way.
}
```
Then you can setup a server.
```c
srvoptions_t options = {
.mode = LINEAR, // the mode to use
.timeout = 30, // the connection timeout (in this case useless, because of LINEAR)
.maxconnections = 5, // the maximum number of connections
.loglevel = LOG_DEBUG // the log level for the logfile
};
// webserver_t ws_create(const char* name, const char* host (can be NULL for default), const char* port, FILE* logfile, srvoptions_t options);
webserver_t server = ws_create("server_name", NULL, "8080", stderr, options);
```
Now you can add you handlers.
```c
handle_t handle = {
.host = ANY, // the hostname to listen on (ANY can be used)
.path = "/*.c", // yes, you can use wildcards (ANY can still be used)
.handler = ¬_found // function pointer of the handler
};
ws_handle_add(&server, handle);
```
Done. Now you can start it.
```c
ws_run(&server);
```
Simple as that. : )
Any questions?
### ... Oh, you were talking to me?
-.-
### Is there something missing?
Well, where can I start?
- the other modes (LINEAR is working, but it's not useable in practice).
- SSL/HTTPS support
- management for cookies and sessions
- index-handlers
- cgi-handlers
## Okay, anything else to do?
Yes:
- extracting the ws_*_run-functions plus their own dependencies to other files (I hate files with more than 1000 lines. D: )
- comments (Yes I know, I'm lazy on that.)
- some security features would be nice (timeouts, ...)
