从Servlet获取JSP页面的HTML

Question

A jsp page in which dynamic datas are there.

I want to get the html of the jsp page which is shown in the browser , from the servlet.

I want to store the html of the jsp in a String variable.

is it possible to get the html source of the jsp file from a servlet. If yes . How?

Answer 1

Use commons http client, which helps in making GET or POST requests from java application.

You can pass all the data required like authentication params or.. session id's etc.

As per your requirement you can get content of completely rendered HTML source using the same.

Much more details can be found here along with good examples

Answer 2

Unless I'm misunderstanding your question, this is simply a matter of using the wget or curl command (or the Windows equivalent) to fetch the page and save it in a file.

(This won't work if the page contains Javascript that must be executed in order to fetch or render the data. For that use-case, refer to the answers to this question .)
