go-zero docker-compose 搭建课件服务（三）：编写courseware api服务
0.1源码地址
https://github.com/liuyuede123/go-zero-courseware
1、生成api相关文件
# 到之前创建的courseware/api目录下
goctl api go -api courseware.api -dir . -style gozero
2、courseware/api/etc/user.yaml下增加rpc配置
Name: courseware
Host: 0.0.0.0
Port: 8400
CoursewareRpc:
Etcd:
Hosts:
- etcd:2379
Key: courseware.rpc
3、courseware/api/internal/config/config.go下增加CoursewareRpc
package config
import (
"github.com/zeromicro/go-zero/rest"
"github.com/zeromicro/go-zero/zrpc"
)
type Config struct {
rest.RestConf
CoursewareRpc zrpc.RpcClientConf
}
3、courseware/api/internal/svc/servicecontext.go下增加CoursewareRpc配置
package svc
import (
"github.com/zeromicro/go-zero/zrpc"
"go-zero-courseware/courseware/api/internal/config"
"go-zero-courseware/courseware/rpc/coursewareclient"
)
type ServiceContext struct {
Config config.Config
CoursewareRpc coursewareclient.Courseware
}
func NewServiceContext(c config.Config) *ServiceContext {
return &ServiceContext{
Config: c,
CoursewareRpc: coursewareclient.NewCourseware(zrpc.MustNewClient(c.CoursewareRpc)),
}
}
4、补充增删改查相关接口逻辑

}
