The order of the location directives is not important – the most specific match is chosen. The session cookie is returned in response to a GET /api/v1/platform/login request. As APIs evolve, it’s sometimes necessary to make changes that break strict backward compatibility and require clients to be updated. This (optional) behavior requires that API clients make requests only to the valid URIs included in the API documentation, and prevents unauthorized clients from discovering the URI structure of the APIs published through the API gateway. HTML5/JavaScript-based UI for desktop and mobile browsers - HTML is generated by a server-side web application 2. The primary function of the API gateway is to provide a single, consistent entry point for multiple APIs, regardless of how they are implemented or deployed at the backend. The NGINX Controller API uses session cookies to authenticate requests. The NGINX Plus configuration for validating JWTs is very simple. Users can also be prompted to grant the application visibility into their access levels. Here we use multiple IP address‑port pairs in each upstream block to indicate where the API code is deployed, but hostnames can also be used. It acts as a reverse proxy, routing requests from clients to services. For API endpoints that are being served by NGINX, NGINX inspects the access tokens and validates whether or not the user is authorized. As the leading high‑performance, lightweight reverse proxy and load balancer, NGINX has the advanced HTTP processing capabilities needed for handling API traffic. The directories and filenames for all API gateway configuration are prefixed with api_. User tries to access the /login or /register pages. Adopting Microservices at Netflix: Lessons for Architectural Design, A Guide to Caching with NGINX and NGINX Plus. To achieve this separation, we create a configuration layout that supports a multi‑purpose NGINX instance, and provides a convenient structure for automating configuration deployment through CI/CD pipelines. And most importantly, how do I implement this logic using nginx? It is unusual to publish APIs without some form of authentication to protect them. The NGINX Plus REST API supports the following HTTP methods: GET – Display information about an upstream group or individual server in it; POST – Add a server to the upstream group; PATCH – Modify the parameters of a particular server; DELETE – Delete a server from the upstream group; The endpoints and methods for the NGINX Plus API … We use sample configuration code to illustrate different use cases. Analytics cookies are off for visitors from the UK or EEA unless they click Accept or submit a form on nginx.com. Follow the instructions here to deactivate analytics cookies. At the heart of modern application architectures is the HTTP API. JSON Web Tokens (JWTs) are increasingly used for API authentication. Nginx gets a 2xx response & redirects the user to the real /someservice Someservice generates the response and sends it back to the user. Join Stack Overflow to learn, share knowledge, and build your career. 1. The top‑level API gateway configuration includes a section that defines how to handle error responses. In this blog post we refer to a hypothetical API for inventory management, the “Warehouse API”. With microservices APIs, we define individual backends for each service; together they function as the complete API. Unlike a web browser, an API gateway cannot send its clients a redirect (code 301 (Moved Permanently)) naming the new location. The format of the map block is simple and easy to integrate into automation workflows that generate the api_keys.conf file from an existing credential store. An API key is essentially a long and complex password issued to the API client as a long‑term credential. Blog› This configuration exposes all of the APIs published by the API gateway at a single entry point, https://api.example.com/ (line 8), protected by TLS as configured on lines 11 through 16. API keys are a shared secret known by the client and the API gateway. Confirm that the user named by the user directive in the NGINX Plus configuration (in /etc/nginx/nginx.conf by convention) has read permission on the JWK file. This video is a quick explanation of how to build a scalable API Gateway with NGINX. Nginx should redirect this call to the API Gateway. When an end user authenticates with Okta, Okta creates a token that represents the user’s level of access. In warehouse_api_simple.conf above, we use the broad approach for the Warehouse API, defining URI prefixes on lines 10 and 14 such that a URI that begins with one of the prefixes is proxied to the appropriate backend service. 3 min read Nginx is a web server that can also be used as a reverse proxy, load balancer, mail proxy, and HTTP cache. The API Gateway might first need to validate the request by calling an authentication service, before routing the request to a backend service. Adding Load Balancing. Copyright © F5, Inc. All rights reserved.Trademarks | Policies | Privacy | California Privacy | Do Not Sell My Personal Information, NGINX Microservices Reference Architecture, Deploying NGINX as an API Gateway, Part 1, Building Microservices: Using an API Gateway, errors generated by the backend services themselves, Authenticating API Clients with JWT and NGINX Plus. The api_gateway.conf file defines the virtual server that exposes NGINX as an API gateway to clients. One can In a browser, enter the address of your NGINX Plus instance and try to log in using the credentials of a user assigned to the application (see Step 10 of Configuring Okta). This blog post makes extensive use of the include directive to aid readability and to enable automation of some parts of the configuration. This configuration adds a further level of protection by sending a standardized error response to the client. In this example we instead add the logic for validating API keys to the top‑level API gateway configuration file, in the form of the following location block called /_validate_apikey. By using HTTP, the advancements in web application delivery that support hyperscale Internet properties can also be used to provide reliable and high‑performance API delivery. powered by Disqus. We offer a suite of technologies for developing and delivering modern applications. The inventory and pricing resources are implemented as separate services and deployed to different backends. Is there a way to prevent my Mac from sleeping during a file copy? Here, we focus on API‑specific authentication methods. NGINX Plus provides support for JWT authentication and sophisticated configuration solutions based on the information contained within the JWT itself. API client authentication with JWT and NGINX Plus. API Gateway verifies if the user is trying to access a secured resource, if it is, verify the token and send back a 2xx response. The use of JSON is not, however, a limitation or requirement of NGINX when deployed as an API gateway; NGINX is agnostic to the architectural style and data formats used by the APIs themselves. My logic here is: First of all, does this logic seems alright to you? Just like the web era had HTTP servers to serve those websites in production, APIs have API Gateways in order to serve APIs in production. NGINX Plus subscribers can also take advantage of dynamic DNS load balancing to have new backends added to the runtime configuration automatically. Here, the nested locations on lines 10 and 14 define two URIs that are more specific than the outer location block; the proxy_pass directive in each nested block routes requests to the appropriate upstream group. I'm currently implementing some logic in my nginx configuration so I can handle authentication and token verification. It may also perform various cross-cutting tasks such as authentication, SSL termination, and rate limiting. Let’s imagine you are building an online store that uses the Microservice architecture pattern and that you are implementing the product details page.You need to develop multiple versions of the product details user interface: 1. We expect API clients to know the correct entry point and to make HTTPS connections by default. Kong’s library of plugins includes simple ways to implement the best known and most widely used methods of API gateway authentication.Simply add the relevant plugin to your Kong deployment and you’re ready to start authorizing consumers in the appropriate way. The Warehouse API is implemented as a collection of discrete microservices and published as a single API. For ease of reading, the rest of the blog refers simply to “NGINX”. Lines 22 through 25 deal with error handling, and are discussed in Responding to Errors below. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. All of the backend API services, for all of the APIs published by the API gateway, are defined in api_backends.conf. Using the API for Dynamic Configuration. Here are the contents of that file: The API keys are defined within a map block. Making statements based on opinion; back them up with references or personal experience. Line 23 refers to errors generated by the backend services themselves. Creating API keys is simple – just encode a random number as in this example. The internal directive on line 29 means that this location cannot be accessed directly by external clients (only by auth_request). An ecommerce site might use a… If you don't deploy a gateway, clients must send requests directly to front-end services. Thanks for contributing an answer to Stack Overflow! This makes NGINX the ideal platform with which to build an API gateway. API Key is usually a long, pseudo-random string included in the request header or request URL. Ethics of warning other labs about possible pitfalls in published research, Save and load the classes definition table in the QGIS reclassify by table tool, Save as GeoPackage Layer Options - use of Description and Identifier, Story about a lazy boy who invents a robot to do all his work, tagline is "laziness is the mother of invention". Uncheck it to withdraw consent. Kong is an API gateway built on top of Nginx. One advantage of using NGINX as an API gateway is that it can perform that role while simultaneously acting as a reverse proxy, load balancer, and web server for existing HTTP traffic. The warehouse_api.conf file is a generic stand‑in for the configuration files discussed below that define the Warehouse API in different ways. NGINX Open Source is a free HTTP web server, mail proxy server, and HTTP, TCP, and UDP reverse proxy and load balancer. F5, Inc. is the company behind NGINX, the popular open source project. NGINX Plus offers several approaches for protecting APIs and authenticating API clients. 15. The most suitable approach for each API depends on the API’s security requirements and whether it is desirable for the backend services to handle invalid URIs. NGINX S3 Gateway. Congratulations! API gateways perform a variety of functions including authenticating API calls, routing requests to the right backends, applying rate limits to prevent overburdening your systems, and handling errors and exceptions. It can translate between web protocols and web‑unfriendly protocols that are used internally. Conservation of Energy with Chemical and Kinetic Energy. Unhandled exceptions may contain stack traces or other sensitive data that we don’t want to be sent to the client. API Gateway allows you to leverage AWS administration and security tools, such as AWS Identity and Access Management (IAM) and Amazon Cognito, to …
