nuxt3 winston 收集自定义日志

在 nuxt.config.js 引入 winston

// nuxt.config.jsimport { resolve } from 'path'import moment from 'moment'import { format, transports } from 'winston'

自定义日志格式

// nuxt.config.jsconst { combine, timestamp, label, printf } = formatconst myFormat = printf(({ level, message, label, timestamp }) => {  return `${timestamp} [${label}] ${level}: ${message}`})

自定义日志存放路径

// nuxt.config.js// 日志存放路径const winstonErrorLogPath = resolve('/var/applogs', './', `error_${moment().format('YYYY-MM-DD')}.log`)const winstonInfoLogPath = resolve('/var/applogs', './', `info_${moment().format('YYYY-MM-DD')}.log`)const jsLogPath = resolve('/var/applogs', './', `js_${moment().format('YYYY-MM-DD')}.log`)const winstonLog =  process.env.NODE_ENV == 'production'    ? {        useDefaultLogger: false,        loggerOptions: {          transports: [            new transports.File({              format: myFormat,              level: 'error',              filename: winstonErrorLogPath,              maxsize: 5 * 1024 * 1024,              json: false,            }),            new transports.File({              format: myFormat,              level: 'info',              filename: winstonInfoLogPath,              maxsize: 5 * 1024 * 1024, // 这个是限制日志文件的大小              json: false,            }),            new transports.File({              format: myFormat,              level: 'silly',              filename: jsLogPath,              maxsize: 5 * 1024 * 1024,              json: false,            }),          ],        },      }    : {}

在 nuxt.config.js 中注册

// nuxt.config.jsexport default {  modules: ['nuxt-winston-log'],  winstonLog,}

在 axios 请求封装模块中使用

  // plugins/interceptor.js  export default function ({ store, route, redirect, $axios, $winstonLog }) {    $axios.onResponse(response => {      // 打印日志 先判断是否有$winstonLog，因为该变量只在服务端存在      if ($winstonLog) {        $winstonLog.info(`[${response.status}] ${response.request.path}`)      }    }    $axios.onError(error => {        // 打印日志 先判断是否有$winstonLog，因为该变量只在服务端存在        if ($winstonLog) {          $winstonLog.error(`[${error.status}] | ${error.request.path} | ${error.message}`)          $winstonLog.error(error.response && error.response.data)      }    }  }
