NodeJS 如何将pino-http与AsyncLocalStorage集成?

我使用pino-http记录请求,代码如下

import { pino } from 'pino';
import { pinoHttp } from 'pino-http';
import { v4 } from 'uuid';

export const logger = pino({
  enabled: process.env.LOG_ENABLED === 'true',
  formatters: {
    level: (label) => {
      return { level: label };
    },
  },
  level: process.env.LOG_LEVEL || 'info',
  name: process.env.LOGGER_NAME,
  redact: {
    paths: ['email', 'password', 'token'],
  },
  timestamp: pino.stdTimeFunctions.isoTime,
});

export const requestLogger = pinoHttp({
  logger,
  genReqId: function (req) {
    req.id = v4();
    return req.id;
  },
  customLogLevel: function (req, res, err) {
    if (res.statusCode >= 400 && res.statusCode < 500) {
      return 'warn';
    } else if (res.statusCode >= 500 || err) {
      return 'error';
    } else if (res.statusCode >= 300 && res.statusCode < 400) {
      return 'silent';
    }
    return 'info';
  },

  customProps: (req, res) => {
    const accountId = req.user ? req.user.id : null;
    const adminId = (req.session || {}).adminUser
      ? req.session.adminUser.id
      : null;
    return {
      accountId,
      adminId,
    };
  },
});

我希望能够通过其他函数跟踪请求id,因此我创建了一个代理记录器

const proxiedLogger = new Proxy(logger, {
  get(target, property, receiver) {
    target = context.getStore()?.get('logger') || target;
    return Reflect.get(target, property, receiver);
  },
});

const contextMiddleware = (req: Request, res: Response, next: NextFunction) => {
  const child = logger.child({ requestId: v4() });
  const store = new Map();
  store.set('logger', child);
  return context.run(store, next);
};

如何让pino-http对所有请求使用这个日志记录器?问题是pino-http附带了自己的genReqId方法

有点晚了,但这是我如何解决这个问题的。
你可以使用pino-http的customProps来实现,基本上你想从存储中提取日志记录器,提取requestId然后返回它。

customProps: (req, res) => {
   const store = context.getStore()?.get("logger");

   if (!store) return {};
   const { requestId } = store.bindings();

   return { requestId }; // attach requestId to request logs
},
