erlang NIFs for http-parser
erlang NIFs for http-parser, see https://github.com/joyent/http-parser
{ok, Parser} = erlhttp:new(),
Request = <<"GET /index.html HTTP/1.1\r\nHost: www.example.com\r\n\r\n">>,
{ok, Rest, Parser1} = erlhttp:update(Request, Parser),
% In a pipelined connection, Rest will contain parts of the next request
{request, Result, Parser2} = erlhttp:parse(Parser1),
% Result is now [{url,<<"/index.html">>},{version,{1,1}},{method,get}]
erlhttp:parse(Parser2),
% continue parsing with the state returned from the previous call to parse
erlhttp:parse
return values:
{request, Result, Parser}
finished parsing request method, url & http version
{headers, Result, Parser}
finished parsing headers
{body, Result, Parser}
finished parsing a body chunk
{done, Result, Parser}
done parsing
{more, Result, Parser}
need more data, call erlhttp:parse/2
The parser will automatically accumulate the request body. To clear the results of the request body, e.g. after writing to a file, call clear_body_results(Parser)
