Hi I am developing Angularjs application and getting some data from Web API. I am able to receive data. I can confirm this because i can see in fiddler and browser developer tool as well. Below is my code. I am returning data as json from web api. I am returning below object.
return Request.CreateResponse(HttpStatusCode.OK, obj);
Object obj contains some fields(data);
In browser i can see response as below.
{"ID":11,"project_id":1,"levels":1,"icon":1,"description":1,"summary":1,"output":1,"owner":1,"role":1,"objectives":1,"reporting":1,"performance_indicators":1,"success":0,"Created":"0001-01-01T00:00:00","Updated":"0001-01-01T00:00:00"}
This is my angular code.
var saveSubs = ProjectSetting_Service.AddProcessSettings(sub);
saveSubs.then(function (data) {
alert((data.data));
alert((data.obj));
}, function (error) {
})
This is my service.js code
this.AddProcessSettings = function (sub) {
$http.post('/api/NCT_ProcessSettings/', sub).success(function (response) { alert(response); });
}
In alert i want to see response data. May i get some help? Any help would be appreciated. Thank you.
According your response, it does not have data in it,
just put the alert as,
var saveSubs = ProjectSetting_Service.AddProcessSettings(sub);
saveSubs.then(function (data) {
alert((data));
alert((data.project_id));
}, function (error) {
})
UPDATE
Your services is not returning anything, just change the service response to return it,
then you can access the data like alert(data.data);

So I'm making a post request to my Express search router where I'm using the node-fetch module to call a remote api:
var fetch = require('node-fetch');
router.route('/search')
//Performs Job Search
.post(function(req, res){
var area = req.body.area;
fetch('https://api.indeed.com/ads/apisearch?publisher=*********&l=' + area)
.then(function(res) {
return res.json();
}).then(function(json) {
console.log(json);
});
})
I'm using angular 1 on the client side to call the router and parse the returned json:
$scope.search = function(){
$http.post('/api/search', $scope.newSearch).success(function(data){
if(data.state == 'success'){
//perform JSON parsing here
}
else{
$scope.error_message = data.message;
}
});
}
I'm just starting out with the MEAN stack and only have a vague idea of how promises work. So my issue is that my angular search function is not getting the JSON string I want to return from my remote API call. But rather the data parameter is getting set to my page html. Eventually the breakpoints I've set in the .then() clauses are hit and my json is returned. So my question is how can I use Anguular to get the JSON values when they are finally returned????
Can you try something like this?
router.route('/search')
//Performs Job Search
.post(function(req, res){
var area = req.body.area;
fetch('https://api.indeed.com/ads/apisearch?publisher=*********&l=' + area)
.then(function(result) {
res.json(result);
//or possibly res.send(result), depending on what indeed responds with
})
})
Turns out I had forgotten that I had middleware in place where if the user was not authenticated when performing the search they were redirected to the login page. So I was getting a bunch of html returned for this login page, rather then my json. What still confuses me is why my breakpoints in search function were ever hit if I was being redirected before ever reaching this function.
I have the following JSON data being received by angularJS. It's being brought in from an ArrayList using a get request.
0: Object
id:1
area: "State"
gender: "Both"
highestEd: 3608662
.... etc
1: Object
id:2
area: "State"
gender: "Both"
highestEd: 3608662
.... etc
However I can't figure out how to access it using either a controller or the UI. I want to be able to store this data in Angular so I can then create graphs using the information. The only way I know it's definitely there is through looking at the response in firefox.
Any help / advice would be greatly appreciated.
Your JSON data is not in proper format. Use JSON lint to check
Use $http.get('/get_url/') to get the response . One sample example for this.
Once you have response in $scope.yourVariable use ng-repeat to loop over it
Take a look at this fiddler here you might get some ideas.
After calling the API using $http from you factory you will have resolve the data that you are getting. The controller needs to call the API method and then bind the resolved data from your factory to the API.
Factory
myApp.factory("Data", function($q, $http) {
return {
getData: function() {
var deferred = $q.defer();
/* --Actual API Call
$http.get("/url")
.then(function(response) {
deferred.resolve(response.data);
})
*/
//Dummy Data
var data = m;
deferred.resolve(data);
return deferred.promise;
}
}
});
Controller
function MyCtrl($scope, Data) {
Data.getData()
.then(function(items) {
$scope.bobs = items;
console.log($scope.bobs);
})
}
Replace the dummy data initialization from factory to the actual API call.
Hi I want to get data from my json file using post method(which is working 5n with get method)
'use strict';
angular.module('myapp').controller('lastWeekWinners',function($http){
var vm= this;
$http.post('http://localhost:9000/json/sample.json').then(function(data){
vm.winnerData=data.data.data;
},function(error){
console.log(error);
});
});
the about code is give error
which means can't we use post method to get the data
This is how u can use the post method in your controller:
'use strict';
angular.module('myapp').controller('lastWeekWinners', controller){
function controller($scope,fetch){
var vm= this;
vm.show = show;
}
function show() {
return fetch.show()
.then(function successCallback(data){
vm.winnerData = data;
}
}, function errorCallback (response) {
console.log(response.statusText);
});
}
});
and in your service :
angular
.module('service',[])
.service('fetch', Service);
function Service($http) {
var fetch = {
show : show
}
return fetch;
function show() {
return $http.get('http://localhost:9000/json/sample.json')
.then(getShowComplete)
.catch(getShowFailed);
function getShowComplete(response){
return response.data;
}
function getShowFailed(error){
console.log("Error:" + error);
}
}
First of all, the difference between GET/POST:
GET is used for getting data, POST is used for saving (and sometimes updating) data. So if you just want to get the json, use GET.
Regarding the specific problem you have here, if you look carefully, you get a 404 code. that means the route was not found. (You can read more about HTTP status code here: http://www.restapitutorial.com/httpstatuscodes.html)
Not sure what server you're using but usually, you're not only defining a route but also the verb of the route (GET/POST/PUT/DELETE), so if you have a route defined like:
GET /users/
This will only work for GET requests, if you try to post for the same route you'll get 404. You have to define the same route for the POST verb.
You can read more about http verbs here: http://www.restapitutorial.com/lessons/httpmethods.html
To do $http.post you need a back end API(PHP,Node Js etc),that system catch your desired post data and save into the db or JSON(Read/Write Method).
Static JSON data just read only possible not write.
Or used Browser $window.localStorage to save data.
I have an Ionic project with a WCF RESTful service, I want to be able to Insert and Update data. I can already view data with GET method but can't find anything on the internet for PUT and POST. How would I be able to accomplish this?
GET Method
$scope.selectedDist= function() {
$http.get("http://192.168.1.113/Service1.svc/GetAllComp")
.success(function(data) {
var obj = data;
var ar = [];
angular.forEach(obj, function(index, element) {
angular.forEach(index, function(indexN, elementN) {
ar.push({CompID: indexN.CompID, CompName: indexN.CompName});
$scope.districts = ar;
});
});
})
.error(function(data) {
console.log("failure");})
};
Post methods I tried
#1
$scope.insertdata = function() {
var ar = [{'M1':$scope.M1, 'M2':$scope.M2,'M3':$scope.M3,'M4':$scope.M4,'M5':$scope.M5,'M6':$scope.M6,'M7':$scope.M7,'M8':$scope.M8,'M9':$scope.M9,'M10':$scope.M10,}]
$http.post("http://192.168.1.113/Service1.svc/GetAllComp", ar)
.success(function(data)
{
console.log("data inserted successfully")
})
.error(function(data)
{
console.log("Error")
})
#2
$scope.insertdata = function() {
var ar = [{'M1':$scope.M1, 'M2':$scope.M2,'M3':$scope.M3,'M4':$scope.M4,'M5':$scope.M5,'M6':$scope.M6,'M7':$scope.M7,'M8':$scope.M8,'M9':$scope.M9,'M10':$scope.M10,}]
$http ({
url : "localhost:15021/Service1.svc/TruckDetails" ,
Method : "POST" ,
headers : {
'Content-Type' : 'Application / json; charset = utf-8'
},
Data : ar
})
Also Would I need to make a POST or PUT method on my Service as well or can I use the GET methods?
You can use a get method, in combination with a querystring to post and put data but that is not what it was designed for and should be avoided for several reasons such as security.
That being said, it is not that difficult to use post and put in angular and in the following , rather naive service , you can see all that is required to do is passing your data in the service function you're invoking.
.service('MyService', function($http) {
this.postMethod = function(data) {
return $http.post('http://my.url', data);
};
this.putMethod = function(id, data) {
return $http.put('http://my.url/' + id, data);
};
}
So that in your controller you can inject and invoke the service methods with the $scope data that needs to be stored.
After taking a look at your attempts you seem to be using the same url for both get and post: "http://192.168.1.113/Service1.svc/GetAllComp" which actually leads me to believe you haven't thought about implementing these methods on your server. Can you confirm this?
Apart from that, it is always usefull to look at statuscodes when trying to send requests because they provide a great deal of information about the nature of the error that occurs. You can investigate that in either your console or an external program such as Fiddler.
P.S.
Deprecation Notice The $http legacy promise methods success and error
have been deprecated. Use the standard then method instead. If
$httpProvider.useLegacyPromiseExtensions is set to false then these
methods will throw $http/legacy error.
I have a page with a main controller and a nested controller for showing details about a product. I want to use a a service in angular to call the server, retrieve a data object and hold that data object. The main controller will call the service to fetch the data and the details controller needs to know it was updated and then access the data. My service looks like this:
.service("productService", function ($http, $q) {
var product = {};
//interface that is returned
return ({
fetchProduct: fetchProduct,
clearProduct: clearProduct,
product: product
});
function fetchProduct(ID) {
var request = $http({
method: "get",
url: "/online/productdata.ashx?itemID=" + ID,
params: {
action: "get"
}
});
return (request.then(handleSuccess, handleError));
};
function clearProduct() {
product = {};
};
// Transform the error response, unwrapping the application dta from
// the API response payload.
function handleError(response) {
// The API response from the server should be returned in a
// nomralized format. However, if the request was not handled by the
// server (or what not handles properly - ex. server error), then we
// may have to normalize it on our end, as best we can.
if (
!angular.isObject(response.data) ||
!response.data.message
) {
return ($q.reject("An unknown error occurred."));
}
// Otherwise, use expected error message.
return ($q.reject(response.data.message));
};
// I attempt to transform the successful response and unwrap the application data
// from the API response payload.
function handleSuccess(response) {
product = response.data;
console.log("Found Data: " + angular.toJson(response.data))
return (response.data);
};
})
In my main controller I set a scope object to the service like this:
$scope.SelectedProduct = productService;
When the user clicks the button to show the product it is called via the $scope handle:
$scope.SelectedProduct.fetchProduct(ID);
The details controller has the same assignment for the $scope.SelectedProduct. I am new to using services but what I understood is that angular would bind to the service object and changes to the property product would trigger binding to any updates. That is not happening - in fact I do see the data after the fetch operation. In the service I have a console.log on the returned data and it is showing the correct data. However the product property is not getting updated. Can someone tell me what I am doing wrong please? Neither controller has access to the data after it is fetched. I understand that I am getting back a promise but the data is never there even after a timeout check.
Try it with a factory instead of a service.
