来自文本有效负载的自定义标签

Question

我正在尝试使用google-cloud / logging-winston云功能。

我想使用prefix和labels，但是当我根据google-cloud / logging-winston文档配置它们时，没有任何效果。

如图所示。标签已添加到textpayload中，并且根本不使用前缀。

任何想法怎么了以及如何解决此问题...

/**
 * Responds to any HTTP request.
 *
 * @param {!express:Request} req HTTP request context.
 * @param {!express:Response} res HTTP response context.
 */
exports.helloWorld = (req, res) => {

  const winston = require('winston');

  // Imports the Google Cloud client library for Winston
  const {LoggingWinston} = require('@google-cloud/logging-winston');

  const loggingWinston = new LoggingWinston({ 
    serviceContext: {
      service: 'winston-test',
      version: '1'
    },
    prefix: 'DataInflow' 
  });

  // Create a Winston logger that streams to Stackdriver Logging
  // Logs will be written to: "projects/YOUR_PROJECT_ID/logs/winston_log"
  const logger = winston.createLogger({
    level: 'info',
    transports: [
      new winston.transports.Console(),
      // Add Stackdriver Logging
      loggingWinston,
    ],
  });

  // Writes some log entries
  //logger.debug('Testing labels', { labels: { module: 'Test Winston Logging' }});
  logger.error('Testing labels', { custom_metadata: 'yes', labels: { module: 'Test Winston Logging' }});

  let message = req.query.message || req.body.message || 'Hello World!';
  res.status(200).send(message);
};

Edit＃1：如果我指定keyFilename = sa-json-file的路径，那么它将起作用。

  const loggingWinston = new LoggingWinston({ 
    serviceContext: {
      service: 'winston-test',
      version: '1'
    },
    prefix: 'DataInflow',
    keyFilename=path-to-sa-json-file.json
  });

但是这很奇怪。 Cloud Function和logging-winston库应使用应用程序默认凭据（ADC）。

因此，如果我与CF一起使用的服务帐户具有stackdriver写入访问权限，那应该没问题。

我的理解错误吗？任何有其他见解的人...

Edit＃2：似乎是Nodejs 10上的Cloud Functions的一个问题。它可以在不指定keyFilename的情况下与Nodejs 8一起很好地工作...非常奇怪...

使用下面的代码，我能够将错误记录到stackdriver以及错误报告中。

在错误报告中，我可以在service -> winston-test下和在堆栈驱动程序中在All logs -> winston_log下找到我的错误

 /**

 *
 * @param {!express:Request} req HTTP request context.
 * @param {!express:Response} res HTTP response context.

exports.helloWorld = (req, res) => {

  const winston = require('winston');

  // Imports the Google Cloud client library for Winston
  const {LoggingWinston} = require('@google-cloud/logging-winston');

  const metadata = {
    resource: {
      type: 'global',
      serviceContext: {
        service: 'winston-test',
        version: '1'
      },
      prefix: 'DataInflow' 
    }
  };


  const resource = {
    // This example targets the "global" resource for simplicity
    type: 'global',
  };


  const loggingWinston = new LoggingWinston({ resource: resource });

  // Create a Winston logger that streams to Stackdriver Logging
  // Logs will be written to: "projects/YOUR_PROJECT_ID/logs/winston_log"
  const logger = winston.createLogger({
    level: 'info',
    transports: [
      new winston.transports.Console(),
      // Add Stackdriver Logging
      loggingWinston,
    ],
  });

  // Writes some log entries
  //logger.debug('Testing labels', { labels: { module: 'Test Winston Logging' }});
  logger.error(Error('Testing labels'));

  let message = req.query.message || req.body.message || 'Hello World!';
  res.status(200).send(message);
};
