Google云功能的console.log信息显示在哪里

Question

当我运行Google云功能时，我如何看到Console.log打印？有云控制台吗？

exports.helloWorld = function helloWorld(req, res) {
  // Example input: {"message": "Hello!"}
  if (req.body.message === undefined) {
    // This is an error case, as "message" is required.
    res.status(400).send('No message defined!');
  } else {
    // Everything is okay.
    console.log(req.body.message);
    res.status(200).send('Success: ' + req.body.message);
  }
};

您可以使用以下任一方法查看云函数日志：

• 云控制台中的Stackdriver日志用户界面
• 使用日志API

// By default, the client will authenticate using the service account file
// specified by the GOOGLE_APPLICATION_CREDENTIALS environment variable and use
// the project specified by the GCLOUD_PROJECT environment variable. See
// https://googlecloudplatform.github.io/gcloud-node/#/docs/google-cloud/latest/guides/authentication
const Logging = require('@google-cloud/logging');

function getLogEntries () {
  // Instantiates a client
  const logging = Logging();

  const options = {
    pageSize: 10,
    filter: 'resource.type="cloud_function"'
  };

  // Retrieve the latest Cloud Function log entries
  // See https://googlecloudplatform.github.io/gcloud-node/#/docs/logging
  return logging.getEntries(options)
    .then(([entries]) => {
      console.log('Entries:');
      entries.forEach((entry) => console.log(entry));
      return entries;
    });
}

• 使用gCloud:

gcloud functions logs read

gcloud functions logs read <FUNCTION_NAME>

gcloud functions logs read <FUNCTION_NAME> --execution-id EXECUTION_ID

gcloud functions logs read -h
