Parse HTTP request line in Java

Question

I would like to have generic way of parsing http request line:

GET /foo?bar=baz HTTP/1.1

would be parsed into object with properties: path, query parameters.

I know that I could do it manually but I wonder if there is a library for that. There is bunch od libraries parsing urls but is there any parsing http requests?

I think OP don't wants to use a whole web server library. He only asks for a library that parses the request, he wants to handle the request by himself. However I also found many topics at SO for the same question but no really satisfying answer. Depending on the complexity of your problem I would just use a simple regex with some capturing groups. Something like `([A-Z]) /(.+) HTTP/([\d\.])` or so, probably needs some finetuning. For extracting the query parameters I think there are some nice libraries but I also found this https://stackoverflow.com/a/11733697/2411243 — Zabuzard, Jun 18 '17 at 17:10
@Frederik.L I don't need a http client, I just want to parse request for wiremock matcher — pixel, Jun 18 '17 at 17:11
Sorry, I thought it was about a lib to build a request and parse the *results* of an http request. — Frederik.L, Jun 18 '17 at 17:13
@Frederik.L No problem, upvotes much obliged - since it would be hard to get an answer with `-1` — pixel, Jun 18 '17 at 17:22
I have a simple library for that: https://github.com/rollback-dropdev/jrestclient There are some other libraries which do basically the same but give it a try, take a look in the examples — Felix, Jun 18 '17 at 17:22

@pixel This probably goes very near of what you need http://www.java2s.com/Code/Java/Network-Protocol/HttpParser.htm and using a lib for parsing a line can be overkill in a way. — Frederik.L, Jun 18 '17 at 18:46

I've end up with extracting path="/foo?bar=baz" and creating new URL("http", "localhost", path)
