i'm using kendovue for an application that i'm creating, the thing is that i must send the bearer token on each request.
but i'm unable to pass it to the server as the function assigned to the beforesend event has the context of the request and not the vue component.
dataSource: new kendo.data.DataSource({
page: 1,
pageSize: 20,
serverPaging: true,
transport: {
read: {
url: "/api/users/list",
dataType: "json",
beforeSend: function (req) {
req.setRequestHeader('Authorization', 'bearer ' + this.$auth.token());
}
}
},
schema: {
total: function (data) {
return data.Data.Total;
},
data: function (data) {
let d = data.Items;
return d;
}
}
}),
can someone point me on the right direction?
regards.
You could define it as method beforeSend: this.beforeSend and add it to the methods collection as below:
methods:{
beforeSend: function (req) {
req.setRequestHeader('Authorization', 'bearer ' + this.$auth.token());
}
}
Here is a sample code that worked correctly at my side: https://stackblitz.com/edit/waonac?file=index.js.

I've got an odd thing happening. On my index page I've got an ajax call that grabs a parameter off of an SVG and then hits the following code:
public async Task<IActionResult> OnPostStateClickAsync(string state)
{
HttpContext.Session.SetObject("CurrentFilters", SearchFilters);
SearchFilters.State = state;
return RedirectToPage("/Search");
}
I'm able to attach a debugger and see everything is working fine behind the scenes. The problem, the UI doesn't ever update and take me to the Search page. If I manually navigate there all the data is loaded and everything is fine.
Not seen this behavior before and I've used the same code in previous projects.
Here is the AJAX call in case it's relevant:
$(document).ready(function () {
$('path').click(function () {
var stateParameter = $(this).attr('id');
$.ajax({
type: "POST",
url: '/Index?handler=StateClick&state=' + stateParameter,
//data: searchTitle,
contentType: "application/json; charset=utf-8",
beforeSend: function (xhr) {
xhr.setRequestHeader("XSRF-TOKEN",
$('input:hidden[name="__RequestVerificationToken"]').val());
},
dataType: "json"
}).done(function (data) {
console.log(data.result);
location.reload();
});
});
});
You can change your code like bellow.
Action:
public async Task<IActionResult> OnPostStateClickAsync(string state)
{
//...
return new JsonResult(new { redirectToUrl = "/Search" });
}
In your Ajax:
$(document).ready(function () {
$('path').click(function () {
var stateParameter = $(this).attr('id');
$.ajax({
type: "POST",
url: '/Index?handler=StateClick&state=' + stateParameter,
//data: searchTitle,
contentType: "application/json; charset=utf-8",
beforeSend: function (xhr) {
xhr.setRequestHeader("XSRF-TOKEN",
$('input:hidden[name="__RequestVerificationToken"]').val());
},
dataType: "json",
success: function (response) {
window.location.href = response.redirectToUrl;
}
});
});
});
Test Result:
I have the following code, in my server. I'm uploading an image using mongoose and s3 and then want to redirect the user to another page but this isn't happening. (the upload is successful).
Routes.js:
{path: '/success', method: 'GET', config: controller.success} ......
controller.js:
imageUpload: {
payload: {
maxBytes: 209715200,
output: 'file',
parse: true
},
handler: function(request, reply) {
var userName = request.auth.credentials.username;
members.findMemberByUsername(userName, function(err, member){
if (err) {
return reply.view('upload', {error: err});
} else if (member) {
var IDImagePath = request.payload.uploadedIDname.path;
console.log(IDImagePath);
members.addID(member, IDImagePath, function(err1){
console.log("add id error", err1);
if (err1){
return reply.view('upload', {error: err1, member: member});
} else {
console.log("SUCCESSFUL!");
return reply.redirect('/success');
}
});
}
});
}
},
success: {
handler: function (request, reply){
request.auth.session.clear();
console.log("success handler working!!");
return reply.view('success');
}
}
The code hits both console.log("SUCCESSFUL") and console.log("success handler working!!") in the controller but the redirect doesn't take place. By the way I'm using 'Jade' as the templating language so I have a success.jade. Thanks.
I found out what the problem was. I'm using AJAX on the client side but didn't have a 'success' method to reload the page:
$('#submitID').click(function(){
var formData = new FormData($('#uploadID')[0]);
$.ajax({
url: '/api/image',
type: 'POST',
xhr: function() { // Custom XMLHttpRequest
var myXhr = $.ajaxSettings.xhr();
if(myXhr.upload){
console.log(myXhr.upload);
}
return myXhr;
},
success: function(data) {
window.location.href = "/success"
},
data: formData,
cache: false,
contentType: false,
processData: false
}, "json");
});
I needed window.location.href = "/success" to reload the page. Please note the jQuery Ajax SUCCESS method is different to my '/success' route, they just happen to be the same word.
I am new to MVC and I am trying to create an application with Knockout.js to send data back to the server dynamically. I am following an example i found at:
http://www.mytecbits.com/microsoft/dot-net/knockout-js-and-bootstrap-with-asp-net-mvc-part-2
It works perfectly off the site, but i am trying to send data to multiple models instead just one as in the example
The Knockout code used in the example to send the data back to the server is
var urlPath = window.location.pathname;
var CreateArticleVM = {
Title: ko.observable(),
Excerpts: ko.observable(),
Content: ko.observable(),
Test: ko.observable(),
btnCreateArticle: function() {
$.ajax({
url: urlPath + '/Create',
type: 'post',
dataType: 'json',
data: ko.toJSON(this),
contentType: 'application/json',
success: function(result) {
window.location.href = urlPath + '/';
},
error: function(err) {
if (err.responseText == "success") {
window.location.href = urlPath + '/';
}
else {
alert(err.responseText);
}
},
complete: function() {}
});
}
};
ko.applyBindings(CreateArticleVM);
How do i modify the above code to be able to accept a FormCollection? Or what is the best solution to my problem?
Thanks
Say your service is expecting more than one argument like following.
[HttpPost]
public String Create(ModelA modela, ModelB modelb)
{
//Server code.
}
In order pass the data for Create method from client side you need to form your postdata as follows.
$.ajax({
url: urlPath + '/Create',
type: 'post',
dataType: 'json',
data: {modela: { "modela data in the expected form" }, modelb : { "modelb data.." } },
contentType: 'application/json',
success: function(result) {
window.location.href = urlPath + '/';
},
.

});
I'm studying Ember.js myself and I'm stuck with a problem I'm creating a sample app and I need to send the client side values to Server Side but I dont know how to do that I know the traditional way like the below code
function create() {
var data = {
'EmailID': $('#emailid').val(),
'password': $('#password').val()
}
$.ajax({
url: '/EmberNew/Home/Create',
type: 'POST',
data:data,
success: function (response) {
alert("hi");
}
});
return false;
}
but In Ember i dont Know How to do that my current code is given below
//Application
App = Em.Application.create();
//Model
App.Users = Em.Object.extend({
name: null,
password:null
});
//View
App.UserTextField = Em.TextField.extend({
insertNew: function () {
App.alertController.alertDetails();
}
});
App.PassTextField = Em.TextField.extend({
insertNew: function () {
App.alertController.alertDetails();
}
});
//controller
App.AlertController = Em.ObjectController.extend({
content: [],
username: '',
password: '',
alertDetails: function () {
var me = this;
var username = me.get("username");
var password = me.get("password");
alert('The User Name Is' + 'username' + 'And Password Is' + 'password');
}
});
App.alertController = App.AlertController.create();
I got the textbox values from alertDetails function and how can I pass them to server side
App.Record = Ember.Object.extend({
name: '',
other: ''
}).reopenClass({
records: [],
find: function() {
var self = this;
$.ajax({
url: "/api/records/",
type: "GET",
cache: false,
dataType: "json",
beforeSend: function() {
//if you want to call this often and need to clear + reload it
return self.records.clear();
},
success: function(results) {
var result;
for (_i = 0, _len = results.length; _i < _len; _i++) {
result = results[_i];
self.records.push(self.records.addObject(App.Record.create(result)));
}
},
error: function() {
return alert("error: failed to load the records");
}
});
return this.records;
}
});
Now that you have your model setup, you can call it from your route model hook
App.RecordsRoute = Ember.Route.extend({
model: function() {
return App.Record.find();
}
});
The find method returns an empty array right away, your template is then bound to it. When the ajax call returns w/ success and you update that array the handlebars template will update it for you w/out any DOM or jQuery glue code
I am having a curiously weird problem, here is my JS code
function ValidateUser(username) {
var userExists = "somevalue";
$.ajax({
contentType: 'application/json, charset=utf-8',
type: "POST",
url: "/Controller/Validate",
data: JSON.stringify({ username: username }),
cache: false,
dataType: "json",
success: function (response) {
alert(response);
if (response == true) {
userExists = true;
alert("user exists: " + userExists);
} else {
alert("user exists: " + userExists);
}
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert('error');
}
});
return userExists;
}
well, the action works fine and validates user correctly, but the function ALWAYS returns "somevalue".....What gives? My hunch is that it has something to do with a function scope. But how do I resolve this issue.
Because the function you're calling $.ajax from returns before the Ajax call completes.
The simple answer is to do the work you need to do in the success function, either with an immediate function (as now), or by setting success to an existing function.
You could also use jQuery's $.when function.
You can use the setting "asynch: false" too, it will lock the browser, disabling any actions while the request is active. Here is your code changed:
function ValidateUser(username) {
var userExists = "somevalue";
$.ajax({
contentType: 'application/json, charset=utf-8',
type: "POST",
url: "/Controller/Validate",
asynch: false,
data: JSON.stringify({ username: username }),
cache: false,
dataType: "json",
success: function (response) {
alert(response);
if (response == true) {
userExists = true;
alert("user exists: " + userExists);
} else {
alert("user exists: " + userExists);
}
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert('error');
}
});
return userExists;
}
