推荐答案

为运行您显示的示例，请遵循文档中的说明:

In order to run the example you show, please follow the instructions in the docs:

1. 下载凭据JSON文件并创建一个指向该文件的环境变量:

1. Download the credentials JSON file and create an environment variable that points to this file:

export GOOGLE_APPLICATION_CREDENTIALS="/path/to/your/credential-file.json"

1. 将代码复制到sample.js文件中，然后运行node sample.js.

1. Copy the code in, i.e., sample.js file and run node sample.js.

另一方面，如果要部署nodejs应用程序，则需要express.js或任何其他框架.

On the other hand, if you want to deploy a nodejs app, you'll need express.js or any other framework.

我在express.js的帮助下完成了以下操作:

I did the following with the help of express.js:

我将您的代码包装在称为saveEntity(datastore)

I wrapped your code in a function called saveEntity(datastore)

然后，我像在 express.js 添加到应用中.google.com/appengine/docs/flexible/nodejs/quickstart"rel =" nofollow noreferrer>示例nodejs应用，然后我从那里调用saveEntity(datastore):

Then I added express.js to the app like in the sample nodejs app and from there I called saveEntity(datastore):

app.get('/', (req, res) => {
    saveEntity(datastore);
    res.status(200).send("Entity saved").end();
}); 

// [START listen]
const PORT = process.env.PORT || 8080;
app.listen(process.env.PORT || 8080, () => {
  console.log(`App listening on port ${PORT}`);
  console.log('Press Ctrl+C to quit.');
});
// [END listen]
// [END app]

module.exports = app;

完整的结果是这样:

// Imports the Google Cloud client library
const Datastore = require('@google-cloud/datastore');
//Needed to create the node app
const express = require('express')

const app = express();

// Your Google Cloud Platform project ID
const projectId = 'my-project-id';

// Creates a client
const datastore = new Datastore({
    projectId: projectId,
});

function saveEntity(datastore){
    // The kind for the new entity
    const kind = 'JulyTask';
    // The name/ID for the new entity
    const name = 'sampletask1';
    // The Cloud Datastore key for the new entity
    const taskKey = datastore.key([kind, name]);

    // Creates entity data
    const task = {
        name: 'Learn something',
        status: 'In progress',
        description: 'Friday 6 July'
    }

    //With the data and the key, create the entity
    const entity = {
        key: taskKey,
        data: task
    }

    // Saves the entity
    datastore
        .upsert(entity)
        .then(() => {
            console.log('Saved:\n' + JSON.stringify(entity));
            return true;
        })
        .catch(err => {
            console.error('ERROR:', err);
            return false;
        });
}

app.get('/', (req, res) => {
    saveEntity(datastore);
    res.status(200).send("Entity saved").end();
}); 

// [START listen]
const PORT = process.env.PORT || 8080;
app.listen(process.env.PORT || 8080, () => {
  console.log(`App listening on port ${PORT}`);
  console.log('Press Ctrl+C to quit.');
});
// [END listen]
// [END app]

module.exports = app;

package.json:

{
    "name": "first-application",
    "version": "1.0.0",
    "description": "First program using cloud datastore",
    "main": "app.js",
    "scripts": {
        "start": "node app.js",
        "deploy": "gcloud app deploy",
        "test": "echo \"Error: no test specified\" && exit 1"
    },
    "author": "Ragav",
    "license": "ISC",
    "dependencies": {
        "@google-cloud/datastore": "^1.4.1",
        "express": "^4.16.3"
    }
}

另外，您应该知道已弃用:

runtime: nodejs
vm: true

您可以改为这样做:

runtime: nodejs
env: flex
service: my-service-name
