• 原因
  • kratos 历史遗留原因 从 bilibili 一直 go-kratos 仓库
• 解决方法 -go.mod 文件中制定版本

github.com/bilibili/kratos v0.3.3

运行不报错，也不成功

• 原因
  • discovery 配置不成功
  • discovery 使用字段（env、node…）
• 解决方法
  • 检查 discovery 注册时候

访问其他节点超时

• 原因
  • 从本地机器代理、开发工具代理设置
  • discovery 的地址 与其他节点不再同一个 discovery
  • 访问节点没有启动
  • AppId 错误
  • 访问节点 grpc 地址错误
• 解决方法
  • 查看访问节点是否在 discovery 中
  • 本地机器 ping 访问节点 grpc 地址
  • 检查开发工具代理设置
  • 查看访问 AppId 是否和 discovery 一致

运行成功没有打印监听端口

• 错误演示

    log.Init(nil) // debug flag: log.dir={path}
    defer log.Close()
    log.Info("user-location start")

• 原因
  • 历史遗留问题
  • kratos 初始化 log 问题
• 解决方法
  • 初始化 log 时只需要给log.Init()不为 nil

    log.Init(&log.Config{Stdout: true}) // debug flag: log.dir={path}
    defer log.Close()
    log.Info("user-location start")
    

启动环境变量错误

LOG_V=1;
LOG_STDOUT=true;
APP_ID=userlocation;
DISCOVERY_NODES=172.12.14.82:7171;
ZONE=sz001;DEPLOY_ENV=dev;

0.7.0 *types.Empty

types.Empty 导致依赖注入生成文件失败

• 解决方法

  把原有的引入包改成以下即可

    types "github.com/gogo/protobuf/types"

Goland Protocl

搜索：Protocol Buffers 、加上自己的项目目录即可

参考链接 proto 设置引导路径

file:///opt/gopath/pkg/mod/github.com/gogo/googleapis@v1.4.0
file:///opt/gopath/pkg/mod/github.com/gogo/protobuf@v1.3.1
