1、学习课程
我们继续接着昨天的步骤,进入服务工作区
$ cd mall/service/order
2、 生成 order model 模型
创建 sql 文件
$ vim model/order.sql
编写 sql 文件
CREATE TABLE `order` (
`id` bigint unsigned NOT NULL AUTO_INCREMENT,
`uid` bigint unsigned NOT NULL DEFAULT '0' COMMENT '用户ID',
`pid` bigint unsigned NOT NULL DEFAULT '0' COMMENT '产品ID',
`amount` int(10) unsigned NOT NULL DEFAULT '0' COMMENT '订单金额',
`status` tinyint(3) unsigned NOT NULL DEFAULT '0' COMMENT '订单状态',
`create_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
`update_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`id`),
KEY `idx_uid` (`uid`),
KEY `idx_pid` (`pid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
运行模板生成命令(注意在 golang 容器下运行)
参考:Linux下部署go-zero,运行goctl model运行模板生成命令报错解决方法
$ goctl model mysql ddl -src ./model/order.sql -dir ./model -c
3、 生成 order api 服务
创建 api 文件
$ vim api/order.api
编写 api 文件
type (
// 订单创建
CreateRequest {
Uid int64 `json:"uid"`
Pid int64 `json:"pid"`
Amount int64 `json:"amount"`
Status int64 `json:"status"`
}
CreateResponse {
Id int64 `json:"id"`
}
// 订单创建
// 订单修改
UpdateRequest {
Id int64 `json:"id"`
Uid int64 `json:"uid,optional"`
Pid int64 `json:"pid,optional"`
Amount int64 `json:"amount,optional"`
Status int64 `json:"status,optional"`
}
UpdateResponse {
}
// 订单修改
// 订单删除
RemoveRequest {
Id int64 `json:"id"`
}
RemoveResponse {
}
// 订单删除
// 订单详情
DetailRequest {
Id int64 `json:"id"`
}
DetailResponse {
Id int64 `json:"id"`
Uid int64 `json:"uid"`
Pid int64 `json:"pid"`
Amount int64 `json:"amount"`
Status int64 `json:"status"`
}
// 订单详情
// 订单列表
ListRequest {
Uid int64 `json:"uid"`
}
ListResponse {
Id int64 `json:"id"`
Uid int64 `json:"uid"`
Pid int64 `json:"pid"`
Amount int64 `json:"amount"`
Status int64 `json:"status"`
}
// 订单列表
)
@server(
jwt: Auth
)
service Order {
@handler Create
post /api/order/create(CreateRequest) returns (CreateResponse)
@handler Update
post /api/order/update(UpdateRequest) returns (UpdateResponse)
@handler Remove
post /api/order/remove(RemoveRequest) returns (RemoveResponse)
@handler Detail
post /api/order/detail(DetailRequest) returns (DetailResponse)
@handler List
post /api/order/list(ListRequest) returns (ListResponse)
}
运行模板生成命令(注意在 golang 容器下运行)
$ goctl api go -api ./api/order.api -dir ./api
4、 生成 order rpc 服务
创建 proto 文件
$ vim rpc/order.proto
编写 proto 文件
syntax = "proto3";
package orderclient;
option go_package = "order";
// 订单创建
message CreateRequest {
int64 Uid = 1;
int64 Pid = 2;
int64 Amount = 3;
int64 Status = 4;
}
message CreateResponse {
int64 id = 1;
}
// 订单创建
// 订单修改
message UpdateRequest {
int64 id = 1;
int64 Uid = 2;
int64 Pid = 3;
int64 Amount = 4;
int64 Status = 5;
}
message UpdateResponse {
}
// 订单修改
// 订单删除
message RemoveRequest {
int64 id = 1;
}
message RemoveResponse {
}
// 订单删除
// 订单详情
message DetailRequest {
int64 id = 1;
}
message DetailResponse {
int64 id = 1;
int64 Uid = 2;
int64 Pid = 3;
int64 Amount = 4;
int64 Status = 5;
}
// 订单详情
// 订单列表
message ListRequest {
int64 uid = 1;
}
message ListResponse {
repeated DetailResponse data = 1;
}
// 订单列表
// 订单支付
message PaidRequest {
int64 id = 1;
}
message PaidResponse {
}
// 订单支付
service Order {
rpc Create(CreateRequest) returns(CreateResponse);
rpc Update(UpdateRequest) returns(UpdateResponse);
rpc Remove(RemoveRequest) returns(RemoveResponse);
rpc Detail(DetailRequest) returns(DetailResponse);
rpc List(ListRequest) returns(ListResponse);
rpc Paid(PaidRequest) returns(PaidResponse);
}
运行模板生成命令(注意在 golang 容器下运行)
$ goctl rpc proto -src ./rpc/order.proto -dir ./rpc

7、 启动 order rpc 服务
提示:启动服务需要在 golang 容器中启动
$ cd mall/service/order/rpc
$ go run order.go -f etc/order.yaml
有的人会报错
root@13258ded6d62:/usr/src/code/mall/service/order/rpc# go run order.go -f etc/order.yaml
2022/03/09 20:55:40 {"@timestamp":"2022-03-09T20:55:40.315+08:00","level":"error","content":"discovbuilder.go:33 bad resolver state"}
2022/03/09 20:55:43 rpc dial: discov://etcd:2379/user.rpc, error: context deadline exceeded, make sure rpc service "user.rpc" is already started
exit status 1
这是要求我们开启 user.rpc 的服务(参考:学习笔记:带你十天轻松搞定 Go 微服务系列(三)- 用户服务)
接着报错
