Javascriptを使ってredash API

実行環境はGAS。ライブラリ公開すれば、汎用性が高まるのでおすすめ。
取得したデータをspreadsheetに書き出すと便利。業務で使う場合は、結構おすすめ。

Poll for Fresh Query Results (including parameters)
参考ソース(python)



var httpOptions = {
  method: "",
  headers: {
    Authorization: "",
    Accept: 'application/json',
    'Content-Type': 'application/json'
  }
}

function setApiKey(api_key){
  httpOptions.headers.Authorization = "Key " + api_key
}

// redash refresh query
function getRefreshQuery(redash_url, query_id){
  var refreshUrl = redash_url + '/api/queries/' + query_id + '/refresh'
  httpOptions.method = 'POST'
  var res = UrlFetchApp.fetch(refreshUrl, httpOptions)
  if(res.getResponseCode() !== 200){
    Logger.log('Refresh Failed')
    return 'Refresh Failed'
  }
  return JSON.parse(res)
}

// redash query result
function getQueryResult(redash_url, query_id, result_id){
  var resultUrl = redash_url + '/api/queries/' + query_id + '/results/'+ result_id + '.json'
  httpOptions.method = 'GET'
  var res = UrlFetchApp.fetch(resultUrl, httpOptions)
  var results = JSON.parse(res).query_result.data.rows
  return results
}

// redash check status 
function getQueryJobStatus(redash_url, job_id){
  var jobcheckUrl = redash_url + '/api/jobs/' + job_id
  httpOptions.method = 'GET'
  var res = UrlFetchApp.fetch(jobcheckUrl, httpOptions)
  return JSON.parse(res)
