How to jump nginx

Redirecting via Nginx routes requests to different URLs. The specific steps include: configuring the server block and specifying the listening port and server name. Use the rewrite directive to specify a redirect type, such as permanent redirect (301) or temporary redirect (302). Use a regular expression to match the request and indicate the redirected URL. Test the redirection through the browser or curl command, check whether the response code is consistent with expectations and whether the request is correctly redirected.

How to use Nginx for redirection

Straight to the point:

Redirecting with Nginx allows you to route requests from one URL to another.

Detailed steps:

1. Configure the server block:

    <code class="nginx">server { listen 80; server_name example.com; # 重定向到www.example.com rewrite ^ https://www.example.com$request_uri? permanent; }</code>

2. Specify the redirect type:

   • 301 Permanent Redirect: Permanently move the request to a new location, and the browser updates the bookmark and links.
   • 302 Temporary redirection: temporarily move the request to a new location, and the browser will not update the bookmarks and links.
   • 303 View other locations: Instructs the browser to get the request response from a different location.
   • 307 Temporary redirect: Similar to 302, but suitable for HTTP POST requests.

3. Set regular expressions:

   • ^ : Match the beginning of the string.
   • $ : Match the end of the string.
   • ? : means that the query string is optional.
   • permanent : Indicates that the redirection is permanent.

4. Test redirection:

   • Use the browser or curl command to access the original URL.
   • Check that the response code is consistent with the expected one.
   • Confirm that the request was correctly redirected to the new URL.

Other redirection options:

• location block: You can use location blocks to redirect based on paths or other conditions.
• proxy_pass: The request can be forwarded to another server and optionally redirected using the return directive.
• if condition: You can use the if condition statement to check the request condition and redirect it as needed.
