Proto的管理 • 错误码管理 • 调试gRPC • 调试信息 • 错误定位 Generate • protoc -I {error proto file} --go-errors_out={output directory} • 实现我们自定义的error类型，方便断言。 • 根据注解的code信息，在错误码中生成对应的grpc status code • 确保错误码唯一，后续在A 配置驱动 • 配置补齐 • 配置工具 • Proto的管理 • 错误码管理 • 调试gRPC • 调试信息 • 错误定位 Check • gRPC的error可以理解为远程error，他是在另一个服务 返回的，所以每次error在客户端是反序列化，new出来 的。是无法通过errors.Is判断其根因。 • 将gRPC的错误码注册到一起，然后通过FromError方式， 利用map唯一性的判别，转化为本地错误，使用 链路 限流熔断 https://ego.gocn.vip/f rame/core/logger.html 报警 索引收敛 日志分类 • 框架日志 • 业务日志 • 慢日志 • Error日志 • Panic日志 mysql的方法叫sql，redis方法叫cmd，框架这里全部统一 用method。降低索引个数 微服务的治理阶段 监控 日志 链路 限流熔断 https://ego
