如何将URL作为@PathVariable传递给Spring RestController？

Question

I want to put URL in GET Request so I can then redirect the user to the given URL.

This is my code so far:

@RequestMapping(value = { "/mapping/{param1}/{redirectLink}" }, method = { RequestMethod.GET})
public void mapping(HttpServletResponse response, @PathVariable("param1") String param1, @PathVariable("redirectLink") String redirectLink) throws IOException {
    // code i wanna run
    response.sendRedirect(backLink);
}

Example url i use to GET - http://localhost:8080/app/controller/redirectionTest/1234/http://localhost:3000/main

So when I call the GET method I wanna run some code then be redirected to http://localhost:3000/main but the URL has slashes in it so it makes it impossible.

Answer 1

Replace the slashes with the standard code: %2F .

http://localhost:8080/app/controller/redirectionTest/1234/http%3A%2F%2Flocalhost%3A3000%2Fmain

I have replaced the colons with %3A just in case you have a problem with that one also

Answer 2

You can try this

@RequestMapping(value = { "/mapping/{param1}" }, method = { RequestMethod.GET})
public void mapping(HttpServletResponse response, @PathVariable("param1") String param1, @RequestParam(required = true, value = "redirectLink") String redirectLink) throws IOException {
    // code i wanna run
    response.sendRedirect(redirectLink);
}

Now, visit http://localhost:8080/app/controller/redirectionTest/1234?redirectLink=http://localhost:3000/main
