Google 云函数 - 无法读取属性 'getApplicationDefault'

Question

我已经部署了一个云函数来调用数据流管道模板，并尝试通过将文件放入云存储桶来触发该函数。

作为node.js我已经完成的先决条件，

npm init
npm install --save googleapis

Index.js

const google = require('googleapis');

exports.goWithTheDataFlow = function(event, callback) {
 const file = event.data;



   google.auth.getApplicationDefault(function (err, authClient, projectId) {
     if (err) {
       throw err;
     }

 console.log(projectId);
     if (authClient.createScopedRequired && authClient.createScopedRequired()) {
       authClient = authClient.createScoped([
         'https://www.googleapis.com/auth/cloud-platform',
         'https://www.googleapis.com/auth/userinfo.email'
       ]);
     }

     const dataflow = google.dataflow({ version: 'v1b3', auth: authClient });
            console.log(`gs://${file.bucket}/${file.name}`);
     dataflow.projects.templates.create({
       projectId: projectId,
       resource: {
         parameters: {
           inputFile: `gs://${file.bucket}/${file.name}`

         },
         jobName: 'cloud-fn-dataflow-test',
         gcsPath: 'gs://jaison/templates/ApacheBeamTemplate'
       }
     }, function(err, response) {
       if (err) {
         console.error("problem running dataflow template, error was: ", err);
       }
       console.log("Dataflow template response: ", response);
       callback();
     });

   });

 callback();
};

用于部署云功能的命令：

gcloud beta functions deploy goWithTheDataFlow --stage-bucket cf100stage --trigger-bucket cf100

数据流（Apache 光束）：我能够从控制台执行数据流模板，下面是模板的路径，

'gs://jaison/templates/ApacheBeamTemplate'

函数因以下错误而崩溃：

TypeError: Cannot read property 'getApplicationDefault' of undefined at exports.goWithTheDataFlow (/user_code/index.js:11:17) at /var/tmp/worker/worker.js:695:16 at /var/tmp/worker/worker.js:660:9 at _combinedTickCallback (internal/process/next_tick.js:73:7) at process._tickDomainCallback (internal/process/next_tick.js:128:9)

看来我缺少图书馆。不知道如何解决这个问题。请帮忙。

我的云函数适用于以下更改，

1.Setting 向上 GOOGLE_APPLICATION_CREDENTIALS 到服务帐户 json 文件

export GOOGLE_APPLICATION_CREDENTIALS="/path/of/svc/json/file.json"

2.index.js

var {google} = require('googleapis');

exports.TriggerBeam = (event, callback) => {


const file = event.data;
  const context = event.context;

  console.log(`Event ${context.eventId}`);
  console.log(`  Event Type: ${context.eventType}`);
  console.log(`  Bucket: ${file.bucket}`);
  console.log(`  File: ${file.name}`);
  console.log(`  Metageneration: ${file.metageneration}`);
  console.log(`  Created: ${file.timeCreated}`);
  console.log(`  Updated: ${file.updated}`);

  google.auth.getApplicationDefault(function (err, authClient, projectId) {
     if (err) {
       throw err;
     }

 console.log(projectId);

 const dataflow = google.dataflow({ version: 'v1b3', auth: authClient });
        console.log(`gs://${file.bucket}/${file.name}`);
 dataflow.projects.templates.create({
   projectId: projectId,
   resource: {
     parameters: {
       inputFile: `gs://${file.bucket}/${file.name}`

     },
     jobName: 'cloud-fn-beam-test',
     gcsPath: 'gs://jaison/templates/ApacheBeamTemplate'
   }
 }, function(err, response) {
   if (err) {
     console.error("problem running dataflow template, error was: ", err);
   }
   console.log("Dataflow template response: ", response);
   callback();
 });

   });

 callback();
};
