A simple callback-based HTTP request/response parser for writing http
servers, clients and proxies.
This gem is built on top of [joyent/http-parser](http://github.com/joyent/http-parser) and its java port [http-parser/http-parser.java](http://github.com/http-parser/http-parser.java).
## Supported Platforms
This gem aims to work on all major Ruby platforms, including:
- MRI 1.8 and 1.9
- Rubinius
- JRuby
- win32
## Usage
```ruby
require "http/parser"
parser = Http::Parser.new
parser.on_headers_complete = proc do
p parser.http_version
p parser.http_method # for requests
p parser.request_url
p parser.status_code # for responses
p parser.headers
end
parser.on_body = proc do |chunk|
# One chunk of the body
p chunk
end
parser.on_message_complete = proc do |env|
# Headers and body is all parsed
puts "Done!"
end
```
# Feed raw data from the socket to the parser
`parser << raw_data`
## Advanced Usage
### Accept callbacks on an object
```ruby
module MyHttpConnection
def connection_completed
@parser = Http::Parser.new(self)
end
def receive_data(data)
@parser << data
end
def on_message_begin
@headers = nil
@body = ''
end
def on_headers_complete(headers)
@headers = headers
end
def on_body(chunk)
@body << chunk
end
def on_message_complete
p [@headers, @body]
end
end
```
### Stop parsing after headers
```ruby
parser = Http::Parser.new
parser.on_headers_complete = proc{ :stop }
offset = parser << request_data
body = request_data[offset..-1]
```
