winston loggingを使用してイベントIDを作成するにはどうすればよいですか？

Question

私たちはkafkaバスからイベントをレンダリングし、winston loggerを使用してファイルシステムに書き込んでいます。そのため、特定の機能を強化するために、ファイルからイベントを検索する必要があります。ログファイル。だから私の質問は、私たちがファイルにログオンするときにwinstonを使ってIDの何らかの種類を生成することが可能かどうかです。

winstonServer.js

var Consumer = { 
    start: function() { 
     var logger = new(winston.Logger)({ 
      level: null, 
      transports: [ 
       new(winston.transports.Console)(), 
       new(winston.transports.File)({ 
        filename: './logs/dit/server.log', 
        maxsize: 1024 * 1024 * 15, // 15MB 
        timestamp: false, 
        maxFiles: 10, 
        json: false, 
        formatter: function(options) { 
         return options.message; 
        } 
       }) 
      ] 
     }); 

     function startConsumer(consumer) { 
      consumer.on('message', function(message) { 
       logger.log('info', message.value); 
       io.io().emit('ditConsumer', message.value); 
      }); 
      consumer.on('error', function(err) { 
       console.log('error', err); 
      }); 
     }; 
     startConsumer(consumer); 
    } 
}

まずあなたがUUID（npm install node-uuid --save）を生成することができます

const uuid = require('node-uuid'); 

をした後、我々は2つのソリューションを持っている：

を

1. 文字列の補間を経由してメッセージをログに記録するためにそれを追加します。

   ... 
   function startConsumer(consumer) { 
       consumer.on('message', function(message) { 
        logger.log('info', `[ID:${uuid.v4()}]${message.value}`); 
        io.io().emit('ditConsumer', message.val); 
       }); 
       consumer.on('error', function(err) { 
        console.log('error', err); 
       }); 
   }; 
   startConsumer(consumer); 
   

   を...

2. メタ経由でメッセージをログに記録することを追加します - これは、両方のトランスポート間の均一性を可能にする：

   var Consumer = { 
       start: function() { 
       const formatter = function(options) { 
          return `[ID:${options.meta.ID}]${options.value || options.meta.value}`; 
         }; 
       var logger = new(winston.Logger)({ 
        level: null, 
        transports: [ 
         new(winston.transports.Console)({formatter}), 
         new(winston.transports.File)({ 
         filename: './logs/dit/server.log', 
         maxsize: 1024 * 1024 * 15, // 15MB 
         timestamp: false, 
         maxFiles: 10, 
         json: false, 
         formatter 
        }) 
       ] 
   }); 
   
   function startConsumer(consumer) { 
       consumer.on('message', function(message) { 
        logger.log('info', message.value, {ID:uuid.v4(), value:message:value}); 
        io.io().emit('ditConsumer', message.value); 
       }); 
       consumer.on('error', function(err) { 
        console.log('error', err); 
       }); 
       }; 
   startConsumer(consumer); 
       } }
