Winston Logging - 如果另一个传输失败，则恢复传输

  我也试图处理这种情况（即当一个传输无法记录消息时（在我的情况下是一个文件 Logger ，如果有人在配置中提到了错误的文件路径，它可能会失败））通过订阅Logger的“错误”事件 . 但我无法让它发挥作用 .

  我试过的是实例化2个不同的Logger One和File Transport，另一个用Mail Transport然后订阅了第一个 Logger 的“error”事件，并在错误事件中使用Logger with Mail传输发送邮件，但是如果没有触发错误事件，我指定了错误的文件路径，并且Node进程崩溃了 .

  var config = require('config');
  var smtpConfig = config.get('serving.smtp');
  var adClickLogConfig = config.get('adClick.logging');
  var adClickMailConfig = config.get('adClick.mail');
  
  var winston = require('winston');
  require('winston-mail').Mail;
  
  function AdClickLoggingService (staticFunctions){
      this.staticFunctions = staticFunctions;
      var fileName  = adClickLogConfig.filePath + "/" + adClickLogConfig.fileName;
      this.fileLogger = new (winston.Logger)({
          transports: [
              new (winston.transports.File)({
                  filename: fileName,
                  level: adClickLogConfig.level,
                  timestamp : adClickLogConfig.timeStamp,
                  maxsize : adClickLogConfig.maxSize,
                  maxFiles : adClickLogConfig.maxFiles,
                  json : adClickLogConfig.json
              })
          ]
      });
  
      this.fileLogger.on('error', function (err) {
          this.emailLogger.info(err);
      });
  
  
      this.fileLogger.on('logging', function (transport, level, msg, meta) {
          console.log('Message logged' + msg);
          // [msg] and [meta] have now been logged at [level] to [transport]
      });
  
      this.emailLogger = new (winston.Logger)({
          transports: [
              new (winston.transports.Mail)({
                  host: smtpConfig.host,
                  tls: smtpConfig.tls,
                  to : adClickMailConfig.toAddress.join(),
                  from : adClickMailConfig.fromAddress,
                  subject : adClickMailConfig.subject
              })
          ]
      });
  
      this.fileLogger.on('error', function (err) {
          console.log(err);
      });
  };
  
  AdClickLoggingService.prototype = {
      logAdClick:function(id, msg){
          msg.adClickId = id;
          msg = this.staticFunctions.convertToString(msg);
          return this.fileLogger.info(msg);
      }
  };
