谷歌云函数访问 BigQuery

Question

我正在尝试编写一个访问我的 bigquery 数据的谷歌云函数。但是，当我运行它时出现错误。如果我在本地模拟器下运行它可以正常工作，但在部署时就不行。

我的 package.json：

{
  "dependencies": {
    "@google-cloud/bigquery": "^0.9.6"
  }
}

index.js

var BigQuery = require('@google-cloud/bigquery');

exports.hello = function hello(req, res) {

    var bigQuery = BigQuery({ projectId: 'influence-ranking' });
    bigQuery.query({
        query: 'SELECT label from `influence-ranking.wikidata.labels` LIMIT 1',
        useLegacySql: false
    }).then(function () {
        return res.status(200).send('hello');
    }).catch(function (error) {
        return res.status(500).json(error);
    });
};

我部署函数：

$ gcloud beta functions deploy hello --stage-bucket influence-ranking-web --trigger-http --project influence-ranking

错误信息中的链接给出了错误：

The API "bigquery.googleapis.com" doesn't exist or you don't have permission to access it

项目参数似乎与我在谷歌云控制台中为我的项目列出的项目编号不对应。所以这让我觉得我以某种方式收到了针对错误项目的请求，但我不知道如何。

Answer 1

我的谷歌云功能帐户出了点问题。

我结束了：

1. 删除我的所有函数
2. 禁用谷歌云功能
3. 重新启用谷歌云功能

现在它可以工作了。

重要的是，现在部署的输出显示：

serviceAccount: influence-ranking@appspot.gserviceaccount.com

所以它使用了正确的服务帐号。
