如果这是Express应用程序，请按照以下步骤操作。

• 安装中间件（可以安装此npm package）
• 在日志文件中，添加以下代码：

const correlator = require('express-correlation-id');

// winston format
winston.format((info) => {
  info.correlationId = correlator.getId();
  return info;
})()

它应该是这样的：

const winston = require('winston');
const correlator = require('express-correlation-id');

const logger = winston.createLogger({
    format: winston.format.combine(
        winston.format((info) => {
            info.correlationId = correlator.getId();
            return info;
        })(),
        winston.format.timestamp({
            format: 'YYYY-MM-DD HH:mm:ss',
        }),
        winston.format.errors({ stack: true }),
        winston.format.splat(),
        winston.format.json()
    ),
    exitOnError: false,
    defaultMeta: {
      // add configuration (https://github.com/winstonjs/winston)
    },
    transports: [
        new winston.transports.File({
            // for the errors (https://github.com/winstonjs/winston)
        }),
        new winston.transports.File({
            // everything else (https://github.com/winstonjs/winston)
        }),
    ],
});

要在Winston中创建correlationId并默认设置每个日志，您需要使用defaultMeta。

var correlationId = Math.random().toString(36).substring(2, 15) + Math.random().toString(36).substring(2, 15)
const winston = require('winston');
const logger = winston.createLogger({
defaultMeta: { correlationId },
    transports: [
        new winston.transports.Console()
    ]
});

logger.info('What rolls down stairs');

import { v4 as uuidv4 } from "uuid";

export async function withCorrelationId(message:string) {
    const id = uuidv4()

    logger.info({
        message,
        id,
    });

    return id
}
