快速网关记录每个请求

Question

I would like to log every single request that express gateway receives, but it seems I can't decide what to log.

I tried to integrate morgan('immediate') From https://github.com/expressjs/morgan

 /* Create a sub app */
  const subApp = express();
  subApp.use(registration({ container }));
  subApp.use(guestRequest({ container }));
  subApp.use(statistics({ container }));
  subApp.use(deleteUser({ container }));
  subApp.use(relationRequest({ container }));

  subApp.use('/docs', swaggerUi.serve, swaggerUi.setup(swaggerDocument, options));
  subApp.use(morgan('immediate'))
  subApp.use(cors({ origin: true, credentials: true }));
  subApp.set('view engine', 'ejs');
  subApp.set('views', viewsPath);

but it looks like its not being used.

Anyone successfully integrated advanced logging in express gateway?

I also tried Longjohn and same issue.

You can do this using Express Gateway out-of-the box.

First, define an apiEndpoint for all requests:

    apiEndpoints:
      all:
        host: "*"
        paths: "*"

Then, set up a pipeline which logs all requests hitting this apiEndpoint:

    policies:
      log

    pipelines:
      logRequest:
        apiEndpoints:
        - all
        policies:
        - log
          - action:
              message: "{req.method} {req.originalUrl} ${JSON.stringify(req.headers)}"

If you need to log more, consider enabling Express Gateway and/or Express diagnostic logging using the environment variables:

• LOG_LEVEL=debug (for Express Gateway)
• DEBUG=express:* (for Express.js)
