How to redirect URL using nginx rewrite

I often need to change nginx configuration at work recently, and learned how to use rewrite in nginx

URL redirection

The URL redirection mentioned here means that when a user visits a URL, it is redirected to another URL.

A common application scenario is to redirect multiple domain names to the same URL (for example, redirect an old domain name to a new domain name).

Redirect static file requests to CDN, etc.

Jump to different sites (PC version, WAP version), etc. according to the user's device.

URL redirection can be achieved by setting window.location on the page through js

It can also be achieved by setting the header in PHP

Of course, you can also use nginx's rewrite function to achieve

nginx rewrite module

rewrite is the static rewrite module of nginx

The basic usage is rewrite pattern replace flag

patten is a regular expression. URLs matching patten will be rewritten as replace. flag is optional.

For example, redirect the old domain name to the new domain name

server
{
 listen 80;
 server_name www.old.com;
 rewrite ".*" http://www.new.com;
}

Keep the path when redirecting to a new domain

server
{
 listen 80;
 server_name www.old.com;
 rewrite "^/(.*)$" http://www.new.com/$1;
}
Rewrite and location work together to jump image files to cdn
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ {
 expires 30d;
 rewrite "^/uploadfile\/(.*)$" http://static.XXX.com/uploadfile/$1;
}

You can add a flag after rewrite . The flag tags are:

last is equivalent to the [L] mark in Apache, indicating that rewrite is completed

break terminates the match and no longer matches the following rules

redirect returns 302 temporary redirection. The address bar will display the redirected address.

Permanent return 301 permanent redirection address bar will display the address after the jump

The above method of using nginx rewrite to achieve URL redirection is all I have to share with you. I hope it can give you a reference. I also hope that you will support 123WORDPRESS.COM.
