Github 地址 https://github.com/SHENCaesar/api-gateway 项目代码运行方式：

1. 启动etcd
2. 启动数据库（在 github.com/SHENCaesar/api-gateway/kitex/dal/mysql/init.go 里设置数据库端口)
3. 启动两个终端分别进入api-gateway/kitex和api-gateway/hz-gateway目录，分别用两个终端运行： go run .
   API 文档 注册学生信息 请求方式

• POST 访问地址 http://localhost:8888/gateway/student 输入参数
• method: register
• biz_params: JSON格式的字符串，包含查询条件。 示例 curl -X POST http://localhost:8888/gateway/student
  -H "Content-Type: application/json"
  -d '{ "method": "register", "biz_params": "{"id": 1, "name":"Emma", "college": {"name": "software college", "address": "逸夫"}, "email": ["emma@pku.com"]}" }' 返回值
• 成功时返回学生注册成功的响应 {"code":0,"data":{"message":"","success":true},"message":"ok"} [图片]
• 失败时返回错误信息。

查询学生信息 请求方式

• POST 访问地址 http://localhost:8888/gateway/student 输入参数
• method: query
• biz_params: JSON格式的字符串，包含查询条件。 示例 curl -X POST http://localhost:8888/gateway/student
