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：

        <!--if you use http proxy start this-->        <dependency>            <groupId>org.apache.shenyu</groupId>            <artifactId>shenyu-spring-boot-starter-plugin-divide</artifactId>            <version>${project.version}</version>        </dependency>
        <dependency>            <groupId>org.apache.shenyu</groupId>            <artifactId>shenyu-spring-boot-starter-plugin-httpclient</artifactId>            <version>${project.version}</version>        </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 -> Proxy -> 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：
