Java-创建Web服务器-处理传入的HTTP请求

Question

I am trying to write a web server in Java (this is my first time so an extremely simple web server). I am not sure how to process the http get and post requests.

Write now all I have is a loop with a server socket excepting connections and using a BufferedReader to take in the incoming message (as text).

I know that you can extend a Servlet class and make use of

• protected void doGet(HttpServletRequest servlet_request, HttpServletResponse servlet_response) , and
• protected void doPost(HttpServletRequest servlet_request, HttpServletResponse servlet_response)

but I cannot work out how to transform/extract a raw incoming message from the socket into the parameters needed for the doGet() and doPost().

Would someone be able to give a basic example and/or explanation of what to do?

Many thanks

Also, as an after thought, would it be simple to extend the web server to process JSP pages?

Any help is greatly appreciated.

Answer 1

for that you need 1st to know http packet format. this link would help

once you know how the packet is formatted, you can extract method (GET/POST/...) and other required info to proceed.
