I'm not sure Oauth2.0 can view my previous posts.Zuul for the Springcloud Micro-service framework can be used very simply can be verified onlineThis article only explains how to resolve conflicts between Oauth2.0 and Zuul packages.Requirements: Create a new Oauth2.0 project the framework for gateway distribution is required on this basis ZuulThe problem is that once you import the required packages for Zuul

1. ConceptZuul is a framework for providing dynamic routing, monitoring, resiliency, security and other edge services on cloud platforms. Zuul corresponds to the front door of all requests from the Web site backend of the device and Netflix streaming app. Another need to understand the concept is the reverse proxy and load balancing, reverse proxy: is the external network to request resources to the intranet, and the resources back to the client, is t

Through the eighth chapter of the study, we have already based on JWT upgraded OAuth2 authentication server, in this chapter, we will give the previous Zuul gateway plus OAuth2 authentication function, so th

Spring Cloud Zuul acts as a gateway that enables request validation filtering and routing to specific services.Example:For example, the request order interface, the message includes authentication information and specific request parameters.By configuring the route to a specific interface, the interface is called through the parameters to return the specific message.Parameter passing:1. Post request, String type JSON2, interface get @responsebody, wil

This essay goes on to learn a more important Component API Gateway service in MicroServices. When we finally have to provide external access to the micro-service architecture, we need a unified access portal, to hide our internal service URL details, which is a bit like the concept of the gateway in the LAN, this is the API Gateway Service has emerged. API Gateway is capable of providing the basic functions of request routing, load balancing, checking and filtering, as well as advanced functions

The book titled "Spring Cloud and Docker microservices architecture in action"-Li, which was completed in 2017-01-12, was written with the spring Cloud play Micro service architecture. Many friends want to first look at the source code, is now released.The code released this time: A total of 70 + Demo Covers Eureka, Ribbon, Feign, Hystrix, Zuul, Spring Cloud Config, Spring Cloud Bus, Spring Cloud Sleuth, Docker, Docker compose, and more.

An API gateway is a server that is the only portal to the system. From an object-oriented design perspective, it is similar to the appearance pattern. The API gateway encapsulates the system's internal architecture and provides a custom API for each client. It may also have other responsibilities, such as authentication, monitoring, load balancing, caching, request fragmentation and management, and static response processing.API gateways are used to provide API interfaces to external application

The following two cases are discussed: If the

Industry API Gateway solutions are many, including commercial, open source. Examples include Tyk, Kong, API Umbrella, Apiaxle, Netflix Zuul, WSO2 API Manager, Clydeio, and more. The following are three common API gateway scenarios. nginx + Luanginx is a high-performance HTTP and reverse proxy server developed by Igor Sysoev for the second rambler.ru site of Russian traffic. 2012, Nginx won the annual Cloud Computing Development award, and grew into t
