玩转WEB接口之四 【HTTP调试测试神器 httpbin实战】

一, 原始需求

萌新小明,入职某网络科技公司,职位互联网开发工程狮.

最近接到一个需求,与某第三方系统对接. 对方提供了接口文档. 小明已经按照接口文档开发好了代码.

现在小明想通过httpbin来测试发送的请求是否正确,他该怎么做?

二, 需求梳理

1. 接口信息

接口地址 请求方式 参数
https://test.00fly.online/get/method1 get param1、param2
https://test.00fly.online/post/method1 post param1、param2、file
https://test.00fly.online/json/method1 jsonbody post param1、param2

2. httpbin信息

服务地址： https://http.00fly.online

3. 流程梳理

观察流程图,发现接口作为httpbin服务的反向代理方来对外提供服务.这样访问接口的时候，便能看到提交的详细请求信息。

一般情况下,实现反向代理常见有2种方案:

  1. 微服务的网关技术
  2. nginx

三, 网关实现

1. 准备工作

test.00fly.online域名ssl证书申请和本地host配置先行，具体请移步 玩转WEB接口之三 【HTTPS证书申请】

2. 源码传送

项目使用Spingcloud gateway 技术来实现

代码结构如下：
如何使用下面的备份文件恢复成原始的项目代码，请移步查阅：神奇代码恢复工具

注意：需要手工放置test.00fly.online.pfx 到 \src\main\resources\data\ssl

3. 代码运行

直接运行 GatewayApplication

或者打包运行

mvn clean package

#直接运行
cd target
java -jar springcloud-gateway-0.0.1.jar

启动成功后系统自动打开浏览器访问： https://test.00fly.online/get/method1

返回json数据如下：

{
  "args": {}, 
  "headers": {
    "A***ept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7",

    "A***ept-Language": "zh-***,zh;q=0.9,en;q=0.8",

  }, 
  "origin": "127.0.0.1, 61.169.67.18", 
  "url": "https://test.00fly.online/get"
}

4. PostMan测试

https://test.00fly.online/post/method1 测试结果

https://test.00fly.online/json/method1 测试结果

四, nginx实现（待调试）

nginx如何实现下面的功能?

get请求统一转发到https://http.00fly.online/get

post请求统一转发到https://http.00fly.online/post

目前还没找到具体的实现方法，哪位大佬有这方面的经验或想法，欢迎交流，不胜感激！

未完待续，有任何问题和建议，都可以向我提问讨论,大家一起进步，谢谢!
