About

http-parser-net is a managed .NET wrapper around Ryan Dahl's node.js http-parser, which is implemented in C.

Usage

http-parser is a streaming parser that relies on callbacks implemented as C function pointers. In .NET callbacks are implemented using delegates, and are commonly exposed as an event-based API. http-parser-net exposes a series of events that are called as data is parsed.

Sample header:

string http = 
    "GET /test HTTP/1.1
" +
    "User-Agent: curl/7.18.0 (i486-pc-linux-gnu)
" +
    "Host: 0.0.0.0=5000
" +
    "Accept: */*
" +
    "
";

Setting up the parser:

Parser parser = new Parser();
parser.Path += new HttpDataDelegate( HttpDataCallback );

Sample callback function:

static void HttpDataCallback( string in_str ) {
    Console.WriteLine( in_str );
}

Parsing data:

parser.Parse( System.Text.Encoding.ASCII.GetBytes( http ) );

Cleaning up:

parser.Dispose();

Status

This .NET implementation is very basic and does not support using the parser to parse server response headers. It also is not optimized for performance and may have some memory leaks. This code was written for future use in Node.net, and I don't expect that it will be robust enough for other uses.
