lebron's Issues

ProductList 的请求参数为什么会有ProductId

go-zero微服务实战系列（五、缓存代码怎么写）里面的 ProductListRequest 结构为什么会有 ProductId

message ProductListRequest {
  int32 category_id = 1;
  int64 cursor = 2;
  int32 ps = 3;
  int64 product_id = 4;
}

请问这个 ProductId 的作用是什么?

Whether the error handling can use the official

For example:

errors.Wrap()
errors.Is()
errors.As()
errors.Unwrap()

为什么不使用response{code date msg } 这种结构

Is there a best practice with parameter verification?

问题请教

同一个服务，为啥要把rpc api admin分开成多个进程？

放一个里面不行么？

mapreduce error

Request Product-Rpc method products mapreduce error

2.Fix: pid is string not int64

like this:

go-zero1.5/goctl1.5 OperationProducts失败

使用go-zero1.5/goctl1.5生成ProductOperationModel代码，请求：grpcurl -plaintext -d '{}' 127.0.0.1:8081 product.Product.OperationProducts，OperationProducts方法报错：context.deadlineExceededError {}

orderitem表结构需要重新更新下

lebron/sql/mall.sql

Line 107 in faf0719

CREATE TABLE `orderitem` (

1.字段按照其他表统一为没有下划线格式
2.id增加AUTO_INCREMENT属性

CREATE TABLE orderitem
(
id bigint(20) unsigned NOT NULL AUTO_INCREMENT COMMENT '订单子表id',
orderid varchar(64) NOT NULL DEFAULT '' COMMENT '订单id',
userid bigint(20) UNSIGNED NOT NULL DEFAULT 0 COMMENT '用户id',
proid bigint(20) UNSIGNED NOT NULL DEFAULT 0 COMMENT '商品id',
proname varchar(100) NOT NULL DEFAULT '' COMMENT '商品名称',
proimage varchar(500) NOT NULL DEFAULT '' COMMENT '商品图片地址',
currentunitprice decimal(20, 2) NOT NULL DEFAULT 0 COMMENT '生成订单时的商品单价，单位是元,保留两位小数',
quantity int(10) NOT NULL DEFAULT 0 COMMENT '商品数量',
totalprice decimal(20, 2) NOT NULL DEFAULT 0 COMMENT '商品总价,单位是元,保留两位小数',
create_time timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
update_time timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
PRIMARY KEY (id),
KEY ix_orderid (orderid),
KEY ix_userid (userid),
KEY ix_proid (proid)
) ENGINE = InnoDB
DEFAULT CHARSET = utf8mb4 COMMENT ='订单明细表';

admin分散到各个项目，权限控制要怎么做？

能提供一份kafka 的docker-compse.yaml 吗 ?

自己配置的一直无法消费

为什么添加rpc会报如下的错误？

cannot use zrpc.MustNewClient(c.GraphRPC) (value of type "github.com/zeromicro/go-zero/zrpc/internal".Client) as grpc.ClientConnInterface value in argument to graph.NewGraphClient: "github.com/zeromicro/go-zero/zrpc/internal".Client does not implement grpc.ClientConnInterface (missing method Invoke)",
