通常按照以下步骤进行定位

  1. 测试环境是否能够复现，若复现在测试环境测试并修复
  2. 有没有异常报警系统，如 sentry，如果有在 sentry 中查看异常堆栈信息以及相关上下文，定位代码
  3. 如果堆栈信息不足够找到问题，看有没有链路追踪工具，如 zipkin。从 sentry 中找到 requestId/traceId，通过 requestId 结合 kibana / ElasticSearch 定位相关的数据库日志/上下游服务链路日志
  4. 如果以上都不行，查看接口相关代码

既然报错，那么一定会在异常上报系统中找到这条问题进行定位。如果在报警系统中没有定位到问题，可以查看

  1. 报警系统是否已限流，致使无法上报
  2. 复现异常时，抓包查看报警相关的 API，查看是否已上报

最怕的是那种接口没报错，但是业务方反馈数据有误的问题了，只能开了 debug，进行代码调试了
