快速-替代重定向

Question

So I was wondering if theres a methode in Express to load a specific page for the user without redirecting the user to the html file.

So instead of res.redirect("https://mywebsite.com/subsite");

maybe theres another method implemented to load the subsite „ subsite.html“ that does not fire the

app.get(/\/subsite(?:\.html)?$/, function(){});

event.

So I want to catch all calls to /subsite and /subsite.html check if the browser/client is allowed to enter the site. If all is correct I will let the browser enter the site otherwise I want to implement a redirect.

What I got so far:

app.get(/\/subsite(?:\.html)?$/, function(req, res) {
  let isValid = checkIfUserIsValid() /* my own logic */
  if (isValid) {
   //how to load subsite.html on the client?
  } else res.redirect("https://mywebsite.com/subsite");
});

Note: I need a method cause I'm stuck in a redirection loop.

Answer 1

app.get(“/xx“, (req, res) => {
    let permissionsOk = // check your user's permissions
    if (permissionsOk) {
        res.send(/* regular page html */);
    } else {
        res.send(/* access denied html */);
    }
});

The idea is that you can have conditional response and serve different html on the same route according to some internal logic
