res.redirect()
Redirect the requesting user agent to the given absolute or relative URL.
Usage
return res.redirect(url);
Or:
return res.redirect(statusCode, url);
Arguments
| Argument | Type | Details | |
|---|---|---|---|
| 1 | statusCode | An optional status code (e.g. 301). (If omitted, a status code of 302 will be assumed.) | |
| 2 | url | A URL expression (see below for complete specification). e.g. "http://google.com" or "/login" |
Details
Sails/Express support a few forms of redirection:
- A fully qualified URI for redirecting to a different domain:
return res.redirect('http://google.com');
- The domain-relative redirect. For example, if you were on http://example.com/admin/post/new, the following redirect to
/checkoutwould land you at http://example.com/checkout:
return res.redirect('/checkout');
- Pathname-relative redirects. If you were on http://example.com/admin/post/new, the following redirect would land you at http//example.com/admin/post:
return res.redirect('..');
- A back redirect, which allows you to redirect a request back from whence it came from using the "Referer" (or "Referrer") header (if omitted, redirects to
/by default):
return res.redirect('back');
Notes
- This method is terminal, meaning that it is generally the last line of code your app should run for a given request (hence the advisory usage of
returnthroughout these docs).- As of Sails v1.x, for HTTP requests,
res.redirect()does not respect the status code established byres.status(). Thanks @Guillaume-Duval and @oshatrk!- When your app calls
res.redirect(), Sails sends a response with status code 302, indicating a temporary redirect. This instructs the user agent to send a new request to the indicated URL. There is no way to force a user agent to follow redirects, but most clients play nicely.- In general, you should not need to use
res.redirect()if a request "wants JSON" (i.e.req.wantsJSON).- If a request originated from the Sails socket client, it always "wants JSON", so the Sails socket client does not follow redirects. For this reason, if an action is called via a WebSocket request using (for example)
io.socket.get(), it will simply receive the appropriate status code and a "Location" header indicating the location of the desired resource. It’s up to the client-side code to decide how to handle redirects for WebSocket requests.
