I'm trying to show JSON data got from API in Google Data Studio.
so I created community connector and in script verified JSON data from api.
here is script code.
function getFields(request) {
var cc = DataStudioApp.createCommunityConnector();
var fields = cc.getFields();
var types = cc.FieldType;
// var aggregations = cc.AggregationType;
fields.newDimension()
.setId('username')
.setType(types.TEXT);
fields.newMetric()
.setId('version')
.setType(types.NUMBER);
fields.newDimension()
.setId('address')
.setType(types.TEXT);
return fields;
}
function getSchema(request) {
var fields = getFields(request).build();
return { schema: fields };
}
function responseToRows(requestedFields, response) {
// Transform parsed data and filter for requested fields
var row = [];
requestedFields.asArray().forEach(function (field) {
switch (field.getId()) {
case 'username':
return row.push(response.result.user.createdByName);
case 'version':
return row.push(response.result.user.version);
case 'address':
return row.push(response.result.user.address);
default:
return row.push('');
}
});
return { values: row };
}
function getData(request) {
var requestedFieldIds = request.fields.map(function(field) {
return field.name;
});
var requestedFields = getFields().forIds(requestedFieldIds);
// Fetch and parse data from API
var options = {
'method' : 'post',
'contentType': 'application/json',
"headers":{ "api-key": request.configParams.api_key },
"payload": "{username:\""+username+"\", password: \""+password+"\"}",
'muteHttpExceptions': true
};
var response = UrlFetchApp.fetch(url, options);
var parsedResponse = JSON.parse(response);
var rows = responseToRows(requestedFields, parsedResponse);
console.log('getData request', parsedResponse);
return {
schema: requestedFields.build(),
rows: rows
};
}
this is JSON file
{
"result": {
"user": {
"type": "User",
"id": 1073787385,
"address": null,
"version": 1675247127459332096,
"createdBy": 310055,
"createdByName": "Jeirick Hiponia",
}
}
}
Result in data studio.
why don't address show?
And why no data? I think row.push in responseToRows() function is issue.
I'd like to show data like this.
I created api connector myself.
This is Code.gs file.
var cc = DataStudioApp.createCommunityConnector();
function getAuthType() {
var AuthTypes = cc.AuthType;
return cc
.newAuthTypeResponse()
.setAuthType(AuthTypes.NONE)
.build();
}
function getConfig(request) {
var config = cc.getConfig();
config.newInfo()
.setId('instructions')
.setText('Enter api url to get data , api token , username and password');
config.newTextInput()
.setId('api_url')
.setName('Enter a api url')
.setPlaceholder('https://');
config.newTextInput()
.setId('api_key')
.setName('Enter a Api Key')
.setHelpText('e.g. xxxxxxxxxxxxxxxxx');
config.newTextInput()
.setId('username')
.setName('Enter a username');
config.newTextInput()
.setId('password')
.setName('Enter a username')
.setType('password');
return config.build();
}
function getFields(request) {
var cc = DataStudioApp.createCommunityConnector();
var fields = cc.getFields();
var types = cc.FieldType;
var aggregations = cc.AggregationType;
fields.newDimension()
.setId('username')
.setType(types.TEXT);
fields.newMetric()
.setId('version')
.setType(types.NUMBER);
fields.newDimension()
.setId('address')
.setType(types.TEXT);
return fields;
}
function getSchema(request) {
var fields = getFields(request).build();
return { schema: fields };
}
function responseToRows(requestedFields, response) {
// Transform parsed data and filter for requested fields
return response.map(function(data) {
var row = [];
requestedFields.asArray().forEach(function (field) {
switch (field.getId()) {
case 'username':
return row.push(data.result.user.createdByName);
case 'version':
return row.push(data.result.user.version);
case 'address':
return row.push(data.result.user.address);
default:
return row.push('');
}
});
return { values: row };
});
}
function getData(request) {
var requestedFieldIds = request.fields.map(function(field) {
return field.name;
});
var requestedFields = getFields().forIds(requestedFieldIds);
// Fetch and parse data from API
const API_KEY = request.configParams.api_key;
var url = request.configParams.api_url;
var options = {
'method' : 'post',
'contentType': 'application/json',
"headers":{ "api-key": API_KEY },
"payload": "{username:\""+request.configParams.username+"\", password: \""+request.configParams.password+"\"}",
'muteHttpExceptions': true
};
var response = UrlFetchApp.fetch(url, options);
var parsedResponse = JSON.parse(response);
var rows = responseToRows(requestedFields, parsedResponse);
return {
schema: requestedFields.build(),
rows: rows
};
}
data from api in postman.
{
"result": {
"user": {
"type": "User",
"id": 1073787385,
"address": null,
"version": 1675221634311192576,
"createdBy": 310055,
"createdByName": "Jeirick Hiponia",
}
}
}
In the Apps Script development environment, Clicked on Deploy > Test deployments to open the Test deployments dialog.
To load your connector in Looker Studio, replace the <HEAD_DEPLOYMENT_ID> placeholder in the following link with your connector's Head Deployment ID and follow the link in your browser:
what is the issue?
Could you please let me know how to extract JSON data received in a string variable in controller. Please see the attachment.Thanks.
$("#btn1").on("click", function () {
var i = new Array();
var j = 0;
$("#sl1").multiselect("getChecked").map(function () {
alert(this.value);
i.push(this.value);
//i[j] = this.value;
//j++;
}).get();
var postData = { values: i };
jQuery.ajaxSettings.traditional = true;
$.post('/TodoList/searchdata', postData, function (data) {
alert(data.Result);
});
//$.ajax({
// type: "POST",
// url: "/TodoList/searchdata",
// data: postData,
// success: function (data) {
// alert(data.Result);
// },
// dataType: "json",
// traditional: true
//});
});
Controller code:-
public void searchdata(String[] values)
{
//{
// JavaScriptSerializer js = new JavaScriptSerializer();
// List<String[][]> data=js.Deserialize<List<String[][]>>(i);
Console.WriteLine(values);
}
You can use Newtonsoft Json library https://www.nuget.org/packages/Newtonsoft.Json/
So As mentioned in the below link use it like below
string json = #"{ 'Email': 'james#example.com', 'Active': true,
'CreatedDate': '2013-01-20T00:00:00Z', 'Roles': [
'User', 'Admin' ] }";
Account account = JsonConvert.DeserializeObject(json);
if you doesn't have model , just use like below
var model = JsonConvert.DeserializeObject(json);
the check the below link
http://www.newtonsoft.com/json/help/html/deserializeobject.htm
Try this
JavaScriptSerializer js = new JavaScriptSerializer();
var data=js.Deserialize<Dictionary<string, List<string>>>(i);
Use This Class :
public class JsonAttributeClass<T> where T:class ,new()
{
public static string EntityToJsonConvertor(T entity)
{
string json = JsonConvert.SerializeObject(entity);
return json;
}
public static T JsonToEntityConvertor(string json)
{
var entity = JsonConvert.DeserializeObject<T>(json);
return entity;
}
}
Here is my JSON method in controller
public JsonResult GetNotificationForAll()
{
Int64 userid = Convert.ToInt64(Session["UserID"]);
string searchcriteria = string.Format("N.notificationfor ={0}", 1);
PODService.Notification[] notification = service.GetNotificationBySearchCriteria(searchcriteria);
return Json(notification, JsonRequestBehavior.AllowGet);
}
Here is my script code for JSON method:
var URL6 = "/Home/GetNotificationForAll";
$.getJSON(URL6, "", function (data) {
var x = { "padding-left": "10px" };
$.each(data, function (index, value) {
$("<td>"
+ value["Notification_Name"]
+ "</td>")
.appendTo("#Allnotification").css(x);
});
});
Here is my view:
<div id="Allnotification" style="color:White;float:left;margin-left:10px"> </div>
I want to show data without page refresh.
i have found the solution.
function NotificationForALL() {
$("#Allnotification").empty();
$.ajax({
type: "GET",
url: "#Url.Action("GetNotificationForAll", "Home")",
dataType: "json",
cache: false,
success: function (data) {
$.each(data, function(index, element) {
var x = { "padding-left": "10px" };
$("<td>"
+ element["Notification_Name"]
+ "</td>") .appendTo("#Allnotification").css(x);
});
setTimeout(function(){NotificationForALL();}, 900000);
}
});
}
NotificationForALL();
Hope it will help to someone
I am doing an app that store some data in the IndexedDB, but I want to load first some data that is in my json file.
Here is my json file:
{
"ciudades":[
{
"ciudad":"Asuncion",
"latitud":-25.2985296,
"longitud":-57.6710677
},
{
"ciudad":"Caaguazu",
"latitud":-25.465034,
"longitud":-56.0183859
},
{
"ciudad":"Ciudad del Este",
"latitud":-25.4933441,
"longitud":-54.6710438
},
{
"ciudad":"San Pedro",
"latitud":-24.1586759,
"longitud":-56.636503
},
{
"ciudad":"Pedro Juan Caballero",
"latitud":-22.5450875,
"longitud":-55.7618963
}
]
}
you follow step
step 1 read mozilla site
step 2 create indexedDB
var ciudades = [
{
"ciudad":"Asuncion",
"latitud":-25.2985296,
"longitud":-57.6710677
},
{
"ciudad":"Caaguazu",
"latitud":-25.465034,
"longitud":-56.0183859
},
{
"ciudad":"Ciudad del Este",
"latitud":-25.4933441,
"longitud":-54.6710438
},
{
"ciudad":"San Pedro",
"latitud":-24.1586759,
"longitud":-56.636503
},
{
"ciudad":"Pedro Juan Caballero",
"latitud":-22.5450875,
"longitud":-55.7618963
}
];
var IDBSetting = {
name: "indexedDBName",
version: 1,
tables: [{
tableName: "ciudades",
keyPath: "seq",
autoIncrement: true,
index: ["ciudad", "latitud", "longitud],
unique: [false, false, false]
}]
};
! function() {
console.log("indexeDB init");
var req = indexedDB.open(IDBSetting.name, IDBSetting.version);
req.onsuccess = function(event) {
console.log("indexedDB open success");
};
req.onerror = function(event) {
console.log("indexed DB open fail");
};
//callback run init or versionUp
req.onupgradeneeded = function(event) {
console.log("init onupgradeneeded indexedDB ");
var db = event.target.result;
for (var i in IDBSetting.tables) {
var OS = db.createObjectStore(IDBSetting.tables[i].tableName, {
keyPath: IDBSetting.tables[i].keyPath,
autoIncrement: IDBSetting.tables[i].autoIncrement
});
for (var j in IDBSetting.tables[i].index) {
OS.createIndex(IDBSetting.tables[i].index[j], IDBSetting.tables[i].index[j], {
unique: IDBSetting.tables[i].unique[j]
});
}
}
}
}();
step 3 addData
var IDBFuncSet = {
//write
addData: function(table, data) {
var req = indexedDB.open(IDBSetting.name, IDBSetting.version);
req.onsuccess = function(event) {
try {
console.log("addData indexedDB open success");
var db = req.result;
var transaction = db.transaction([table], "readwrite");
var objectStore = transaction.objectStore(table);
var objectStoreRequest = objectStore.add(data);
} catch (e) {
console.log("addDataFunction table or data null error");
console.log(e);
}
objectStoreRequest.onsuccess = function(event) {
//console.log("Call data Insert success");
}
objectStoreRequest.onerror = function(event) {
console.log("addData error");
}
};
req.onerror = function(event) {
console.log("addData indexed DB open fail");
};
}
}
for(var i in ciudades){
IDBFuncSet.addData("ciudades",ciudades[i]);
}
step 4 getData
IDBFuncSet.getAllData = function(arr, table) {
try {
var req = indexedDB.open(IDBSetting.name, IDBSetting.version);
req.onsuccess = function(event) {
var db = req.result;
var transaction = db.transaction([table], "readonly");
var objectStore = transaction.objectStore(table);
var objectStoreRequest = objectStore.openCursor();
objectStoreRequest.onsuccess = function(event) {
var cursor = event.target.result;
if (cursor) {
arr.push(cursor.value);
cursor.continue();
} else {
}
}
};
req.onerror = function(event) {
console.log("getAllData indexed DB open fail");
};
} catch (e) {
console.log(e);
}
}
var ciudadesArr = [];
IDBFuncSet.getAllData(ciudadesArr, "ciudades");
console.log(ciudadesArr);
I hope this helps
Here's how I've done mine, thanks to the android-indexeddb package.
angular.module('yourApp', ['indexedDB'])
.config(function($indexedDBProvider) {
$indexedDBProvider
.connection('dbName')
.upgradeDatabase(1, function(event, db, tx) {
var objStore = db.createObjectStore('storeOne', { keyPath: 'stop_id' });
objStore.createIndex('store_id', 'store_id', { unique: false });
})
// the next upgradeDatabase() function is necessary if you
// wish to create another datastore
.upgradeDatabase(2, function(event, db, tx) {
var secondObjectStore = db.createObjectStore('storeTwo', { keyPath: 'my_id' });
secondObjectStore.createIndex('another_id', 'another_id', { unique: false });
});
})
Then in my controller:
angular.module('yourApp')
.controller('homeCtrl', ['$scope', '$http', '$indexedDB', function($scope, $http, $indexedDB) {
$scope.objects = [];
var loadJSON = function(file_name) { ... //load the json file in here}
$indexedDB.openStore('storeOne', function(store) {
var loaded = loadJSON('file_name.json');
store.upsert(loaded).then(function(e) {
console.log('added successfully');
});
});
$indexedDB.openStore('times', function(store) {
var loaded = loadJSON('file_name.json');
store.upsert(loaded).then(function(e) {
console.log('added successfully');
});
});
}]);
Check out the project page to learn more of the tricks up this package's sleeves.
Although this angular-indexeddb page supports queries, for advanced queries like joins, you might wanna consider ydn-db
Getting some pretty nice workflow with both packages.
For the loadJSON() function, it could be something like this:
var loadJSON = function(file_name) {
var data;
$.ajax({
url: '../data/' + file_name,
dataType: 'json',
async: false,
success: function(res_data) {
data = res_data;
console.log('Loaded ' + file_name + ' nicely');
},
error: function(err) {
console.log('error happened');
}
});
return data;
}
There is File API, but that doesn't seem to be a solid standard yet.
What I do at the moment, is have the user open the file, copy it's contents to Clipboard, and paste it into a TextArea element on my web page.
In JavaScript I add a listener to the TextArea's change event and parse the text content into JSON, which is then written to indexedDB.
