send json via paypal.request.post() from PayPal checkout.js - json

paypal.Button.render({
payment: function() {
var booksPurchaseRequest = {};
booksPurchaseRequest.amount = 20;
return paypal.request
.post(CREATE_PAYMENT_URL, JSON.stringify(booksPurchaseRequest))
.then(function(data) {
return data.paymentId;
});
}
}, '#paypal-button');
In such approach on back-end server I'm receiving data in application/x-www-form-urlencoded format, but I need application/json. How can I achieve that? Can paypal.request.post() be replaced with simple $.ajax()?


return paypal.request({
method: 'post',
url: '/foo/bar',
json: {
foo: 'bar'
}
}).then(function(response) {
})
Or you can just use jQuery, you just need to return a promise

Getting JSON Response back from MVC Controller from Ajax call

I have a razor view which calls a method on an MVC controller via Ajax. All is working except I am not receiving anything back even though I am returning a JSON result. The "data" element in the success portion is undefined.
Here is the Ajax call:
callback: function(result) {
if (result === true) {
$.ajax(
{
type: "POST", //HTTP POST Method
url: "AddEmployee", // Controller/View
data: { //Passing data
Name: $("#txtName").val(), //Reading text box values using Jquery
City: $("#txtAddress").val(),
Address: $("#txtcity").val(),
Phone: $("#txtPhone").val(),
SSN: $("#txtSsn").val(),
success: function (data) {
alert(data.ResponseMessage);
//$('<div>' + data + '</div>').appendTo('#divConfirm');
}
}
});
Here is my controller:
[HttpPost]
public JsonResult AddEmployee(EmpModel obj)
{
bool isSaved = AddDetails(obj);
Response response = new Response {ResponseMessage = "Success!"};
return Json(response);
}

You put wrong } in data, my friend:
Name: $("#txtName").val(), //Reading text box values using Jquery
City: $("#txtAddress").val(),
Address: $("#txtcity").val(),
Phone: $("#txtPhone").val(),
SSN: $("#txtSsn").val() },
success: function (data) {
alert(data.ResponseMessage);
//$('<div>' + data + '</div>').appendTo('#divConfirm');
}

How can I send requests to JSON?

I'm coding a mobile application with ionic. I have to get a data (daily changing data) from a web page with JSON, but I want to get old data too. For example:
data.json?date=2016-11-10
data.json?data=2016-12-10
How can I send request to JSON?

To send data from PHP, once you get your data from the database, the array will apply json_encode($array); and to return you put return json_encode ($ array);
Try this!
var date = '2016-11-10';
$http({
method: 'GET',
url: data.php,
params: {date: date},
dataType: "json",
contentType: "application/json"
}).then(function(response) {
});

The question is confusing, so I'm not sure how to answer. If you are having trouble formatting a request to a REST service, you will need to find out how the service expects the date to be formatted in your field-value pair i.e:
date=2016/11/10 or date=20161110
If those don't work, this answer may help The "right" JSON date format
However, if you are actually wondering how to serialize a date in JSON, this link may help http://www.newtonsoft.com/json/help/html/datesinjson.htm

I prefer to use services for ajax requests.
Create a Service
//Service
(function() {
'use strict';
angular
.module('appName')
.factory('appAjaxSvc', appAjaxSvc);
appAjaxSvc.$inject = ['$http', '$log', '$q'];
/* #ngInject */
function appAjaxSvc($http, $log, $q) {
return {
getData:function (date){
//Create a promise using promise library
var deferred = $q.defer();
$http({
method: 'GET',
url:'/url?date='+date
}).
success(function(data, status, headers,config){
deferred.resolve(data);
}).
error(function(data, status, headers,config){
deferred.reject(status);
});
return deferred.promise;
},
};
}
})();
Then Use it in Controller
(function() {
angular
.module('appName')
.controller('appCtrl', appCtrl);
appCtrl.$inject = ['$scope', '$stateParams', 'appAjaxSvc'];
/* #ngInject */
function appCtrl($scope, $stateParams, appAjaxSvc) {
var vm = this;
vm.title = 'appCtrl';
activate();
////////////////
function activate() {
appAjaxSvc.getData(date).then(function(response) {
//do something
}, function(error) {
alert(error)
});
}
}
})();

Pass a value from controller as JSON in codeigniter to view that contain on Angular Js

I need to use this:
http://demos.telerik.com/kendo-ui/multiselect/angular
but my problem when I try to change the url to:
read: {
url: base_url+"index.php/welcome/findAll",
}
and the function findAll in controller contain on:
public function findAll()
{
$listproduct = $this->mproduct->findAll();
echo json_encode($listproduct);
}
The list of options become empty.

You controller seems to be fine as long as it returns a valid JSON format.. in your AngularJS controller try doing:
$scope.MyFunction = function()
{
console.log("posting data....");
$http({
method : 'GET',
url : 'http://domain/controller/method_that_return_json',
headers: {'Content-Type': 'application/json'},
data : JSON.stringify({What you want to return from JSON here})
}).success(function(data) {
console.log(data);
});
}
Another aproach:
$http.get("http://www.domain.com/pathtojson)
.success(function(response) {
$scope.related = response;
});
}

Displaying json data in angularjs

}).success(function (data) {
$log.log(data);
return data;
});
return homeRates;
};

View
<ul id="home-rates" ng-repeat="rate in exchangeRates">
<li><span class='rate-symbol'>{{rate.Name}}</span><span class='rate-amount'>{{rate.Price}}</span></li>
</ul>
I would like to display the data returned by in the service in the view but it doesn't seem to be working. Please help

First, $http invocations all return a promise, not the result of your request. Your service should just return the result of the $http call, and your controller needs to attach a .success handler to receive the data and set it on the scope of your controller.
.service('HomeExchangeList', function ($rootScope, $http, $log) {
this.getHomeExchange = function() {
var rates = $http({
method: 'GET',
url: 'http://localhost:8080/feeds/homerates_android.php'
}).success(function (data) {
$log.log(data);
// removed your return data; it doesn't do anything, and this success is only added to log the result. if you don't need the log other than for debugging, get rid of this success handler too.
});
return rates;
};
})
function HomeCtrl($scope, Page, $location, HomeExchangeList) {
HomeExchangeList.getHomeExchange().success(function(data) {
$scope.exchangeRates = data;
});
}
Second, the root of your JSON is not an array, so you can't enumerate through just exchangeRates alone. Perhaps you meant exchangeRates.record.

try to assign data.record to $scope.exchangeRates instead of data... as data doesnt hold the array of records... it holds record which then holds the array

First of all, your service function always returns undefined:
var rates = ...,
return homeRates;
It should be
return rates;
Second, once that is fixed, the service doesn't return data. It returns a promise, and you can't iterate on a promise. What you need in the controller is:
HomeExchangeList.getHomeExchange().then(function(data) {
$scope.rates = data.record;
}
The call to $scope.$on doesn't make any sense. $scope.$on is used to listen for events. Not to get data from a promise.
And finally, your view must iterate over these retes, and not over exchangeRates:
ng-repeat="rate in rates">

How to post json data with extJS

I'm a bit of a newb with both extJS and json. What is the most painless route to POSTing json data using extJS? I'm not really interested any GUI features, just using the framework to send some sample data.

Ext.Ajax.request({
url: 'foo.php', // where you wanna post
success: passFn, // function called on success
failure: failFn,
params: { foo: 'bar' } // your json data
});

The following will identify as 'POST' request
Ext.Ajax.request({
url: 'foo.php', // where you wanna post
success: passFn, // function called on success
failure: failFn,
jsonData: { foo: 'bar' } // your json data
});
The following will identify as 'GET' request
Ext.Ajax.request({
url: 'foo.php', // where you wanna make the get request
success: passFn, // function called on success
failure: failFn,
params: { foo: 'bar' } // your json data
});

Just to add my two cents:
//
//Encoding to JSON:
//
var myObj = {
visit: "http://thecodeabode.blogspot.com/"
};
var jsonStr = Ext.encode(myObj);
//
// Decoding from JSON
//
var myObjCopy = Ext.decode(jsonStr);
document.location.href = myObj.visit;

The examples posted here show the basic idea. For complete details on all configurable options see the Ext.Ajax docs.

Code Snippet:
Ext.Ajax.request({
url: "https://reqres.in/api/users",
success: function (response) {
Ext.Msg.alert("success", response.responseText);
},
failure: function () {
Ext.Msg.alert("failure", "failed to load")
},
params: {
"name": "morpheus",
"job": "leader"
}
});
