Use Nginx Proxy Manager to implement API gateway authentication and authorization

As an important part of modern Internet application development, API gateway not only provides interface calls, but also The security of the interface needs to be ensured. Among them, authentication and authorization are indispensable functions of the API gateway, which are used to verify the identity of the requester and grant access rights. This article will introduce how to use Nginx Proxy Manager to implement API gateway authentication and authorization, and provide specific code examples.

1. What is Nginx Proxy Manager

Nginx Proxy Manager is a reverse proxy and load balancing management tool based on Nginx. It provides a visual management interface to facilitate users to configure and manage Nginx proxy rules. Nginx Proxy Manager can forward requests by configuring rules and supports adding custom middleware to extend the functions of Nginx.

2. Authentication and Authorization

In API gateway, authentication and authorization are key security measures. Authentication is used to verify the identity of the requester, usually using API keys, usernames and passwords, etc. Authorization is to judge the requester's permissions after passing the authentication and decide whether to allow access to an interface.

3. Use Nginx Proxy Manager to implement authentication and authorization

1. Install Nginx Proxy Manager

First, we need to install Nginx Proxy Manager on the server. It can be installed through the following command:

$ sudo apt-get install nginx
$ sudo apt-get install npm
$ sudo npm install -g npx
$ sudo npx create-npx npx

2. Configure authentication

On the management interface of Nginx Proxy Manager, find the corresponding proxy rule configuration item and add it to the middleware configuration Authentication middleware. Authentication middleware can perform verification based on the identity information provided by the requester. The following is a sample code that uses API keys for authentication:

location /api {
    auth_basic "API Authentication";
    auth_basic_user_file /etc/nginx/.htpasswd;
    proxy_pass http://backend;
}

In the above code, auth_basic is used to set the authentication prompt information, auth_basic_user_file is used to specify the save File of API key. According to actual needs, you can customize the authentication method and add corresponding verification logic.

3. Configuring Authorization

Authorization is implemented in a similar way to authentication. Authorization middleware is also added to the middleware configuration of the proxy rule configuration item. The following is a simple authorization sample code:

location /api {
    auth_basic "API Authentication";
    auth_basic_user_file /etc/nginx/.htpasswd;
    proxy_pass http://backend;
    if ($http_token != "123456") {
        return 403;
    }
}

In the above code, it is determined whether to return a 403 error (ie, no permission) by judging whether the request contains the correct access token (token). According to actual needs, you can customize the authorization method and add corresponding authorization logic.

4. Summary

This article introduces the method of using Nginx Proxy Manager to implement API gateway authentication and authorization, and provides specific code examples. By configuring authentication and authorization middleware, we can flexibly authenticate and control API requests based on business needs to ensure the security of interface calls. I hope this article will help you understand and practice API gateway authentication and authorization.
