Http快速开始

本文档演示如何将Http服务接入到Apache ShenYu网关。您可以直接在工程下找到本文档的示例代码

环境准备

请参考运维部署的内容,选择一种方式启动shenyu-admin。比如,通过 本地部署 启动Apache ShenYu后台管理系统。

启动成功后,需要在基础配置->插件管理中,把divide 插件设置为开启。在Apache ShenYu网关中,Http请求是由divide插件进行处理。

启动网关,如果是通过源码的方式,直接运行shenyu-bootstrap中的ShenyuBootstrapApplication

注意,在启动前,请确保网关已经引入相关依赖。

引入网关对Http的代理插件,在网关的 pom.xml 文件中增加如下依赖:

  1. <!--if you use http proxy start this-->
  2. <dependency>
  3. <groupId>org.apache.shenyu</groupId>
  4. <artifactId>shenyu-spring-boot-starter-plugin-divide</artifactId>
  5. <version>${project.version}</version>
  6. </dependency>
  7. <dependency>
  8. <groupId>org.apache.shenyu</groupId>
  9. <artifactId>shenyu-spring-boot-starter-plugin-httpclient</artifactId>
  10. <version>${project.version}</version>
  11. </dependency>

运行shenyu-examples-http项目

下载 shenyu-examples-http

运行org.apache.shenyu.examples.http.ShenyuTestHttpApplicationmain方法启动项目。

成功启动会有如下日志:

测试Http请求

shenyu-examples-http项目成功启动之后会自动把加 @ShenyuSpringMvcClient 注解的接口方法注册到网关。

打开插件列表 -> http process -> divide可以看到插件规则配置列表:

下面使用postman模拟http的方式来请求你的http服务:
