Question

我正在尝试运行以下GQL查询：

function gqlExample(callback) {
  datastore.runQuery({
    gqlQuery: {
      queryString: 'SELECT * FROM Person',
    }
  }).execute(function(err, result) {
    if (!err) {
      // Iterate over the results and return the entities.
      result = (result.batch.entityResults || []).map(
        function(entityResult) {
          return entityResult.entity;
        });
    }
    callback(err, result);
  });
}

我在下一页上找到了上面的例子： http://ec2-54-66-129-240.ap-southeast-2.compute.amazonaws.com/httrack/docs/cloud.google.com/datastore/docs/concepts/gql.html

它声明它是一个有效的node.js示例，但在运行查询时出现以下错误：

/Users/xxxx/relay-fullstack/server/data/campaign-datastore.js:245
  }).execute(function (err, result) {
     ^
TypeError: ds.runQuery(...).execute is not a function

我正在使用最新版本的google cloud for node：

"google-cloud": "^0.38.3",

有没有人使用gcloud和节点正确执行GQL查询？任何帮助将不胜感激。

这显然是数据存储区文档的缓存版本。那些Node.js片段正在使用名为googleapis的不同库：https://github.com/google/google-api-nodejs-client

另一个库gcloud-node目前不支持GQL。

GQL查询无法使用gcloud（google-cloud）和node.js
