I'm new to DOJO and following the documentation on Dojo official website i wrote my code for POST request as below. But its not working and its giving me error "Unable to load myURL status: 0".
Please help.
require(["dojo/request","dojo/dom","dojo/on"],function(request,dom,on){
try{
//Access TextFields Value
var txt_UserName=dom.byId("usrName");
var txt_Password=dom.byId("password");
//Attaching click event on Button
on(dom.byId("loginButton"),"click",function(evt){
//alert(txt_UserName.value);
request.post(myURL,{
handleAs: "json",
data:{
userId: txt_UserName.value,
password: txt_Password.value,
},
headers:{
"Content-Type": "application/x-www-form-urlencoded",
}
}).then(function(response){
alert(response);
},
function(error){
alert(error);
}
);
});
}
catch(error){
alert(error.message);
}});

I have the following request to the jsreport engine:
$.ajax({
method: "POST",
contentType: "application/json",
dataType: "jsonp",
url: "http://localhost:5488/api/report",
data: {
template: {
shortid: "ry6HoQRee"
},
data: {
"D": "5"
}
},
success: function (s) {
window.open("data:application/pdf,base64," + escape(s.responseText));
},
error: function (s) {
console.log(s);
}
});
However I can't find a way to read it inside the report template:
<span>{{data.D}}</span>
How do I refer to the data object that is inside the POST body
jquery doesn't support binary responses like pdf. You should rather use XMLHttpRequest:
var xhr = new XMLHttpRequest()
xhr.open('POST', 'http://localhost:5488/api/report', true)
xhr.setRequestHeader('Content-type', 'application/json; charset=utf-8')
xhr.responseType = 'arraybuffer'
xhr.onload = function(e) {
if (this.status == 200) {
window.open("data:application/pdf;base64," + window.btoa(String.fromCharCode.apply(null, new Uint8Array(xhr.response))));
}
}
xhr.send(JSON.stringify({
template: {
shortid: 'Syeopu_xe'
},
data: {
'D': '5'
}
}))
Example of reaching data using handlebars templating engine
<span>{{D}}</span>
Additionally...
You may also take a look at jsreport official browser client library. It wraps the XmlHttpRequest calls into more elegant calls:
jsreport.serverUrl = 'http://localhost:3000';
var request = {
template: {
content: 'foo', engine: 'none', recipe: 'phantom-pdf'
}
};
//display report in the new tab
jsreport.render('_blank', request);
or in async fashion
jsreport.renderAsync(request).then(function(res) {
//open in new window
window.open(res.toDataURI())
//open download dialog
res.download('test.pdf')
});
I have the following:
bidAmount: {
amount: 0
},
userToken: {
token: null
},
this.$http.post('/place-bet', this.bidAmount, function(response) {
alert(response);
});
How do I send both this.bidAmount and this.userToken
I have tried this however it doesn't send correctly:
this.$http.post('/place-bet', [this.userToken, this.bidAmount], function(response) {
alert(response);
});
You should always post an object, that way you can access the variables on the server using their respective keys:
this.$http.post('/place-bet', {userToken: this.userToken, bidAmount: this.bidAmount}, function(response) {
alert(response);
});
or...
this.$http.post('/place-bet', {data:[this.userToken, this.bidAmount]}, function(response) {
alert(response);
});
Create an object in data object
new vue({
el:'#point'
data: {
newdata:{
token:'',
bidAmount:''
}
}
});
Now you can
this.$http.post('/place-bet',this.newdata, function(response) {
alert(response);
});
The problem is the session will expire after a predetermined amount of time. Many times when this happens the ember.js app is still loaded. So all requests to the backend return a 401 {not autorized} response.
so i need to redirect user to the login page and clear the last token from the session so that isauthenticated property becomes false.
I am using custom authenticator.
import Base from 'ember-simple-auth/authenticators/base';
import ENV from '../config/environment';
import Ember from 'ember';
export default Base.extend({
restore: function(data) {
return new Ember.RSVP.Promise(function (resolve, reject) {
if (!Ember.isEmpty(data.token)) {
resolve(data);
}
else {
reject();
}
});
},
authenticate: function(options) {
return new Ember.RSVP.Promise(function(resolve, reject) {
Ember.$.ajax({
type: "POST",
contentType: 'application/json',
url: ENV.CONSTANTS.API_URL + '/authentication',
data: JSON.stringify({
username: options.username,
password: options.password
})
}).then(function(response) {
if(!response.token){
Ember.run(function(){
reject(response.message);
});
} else {
Ember.run(function() {
resolve(response);
});
}
}, function(xhr, status, error) {
Ember.run(function() {
reject(xhr.responseJSON || xhr.responseText);
});
});
});
},
invalidate: function(data) {
return new Ember.RSVP.Promise(function(resolve, reject) {
Ember.$.ajax({
type: "GET",
url: ENV.CONSTANTS.API_URL + '/authentication/logout'
}).then(function(response) {
Ember.run(function() {
resolve(response);
});
}, function(xhr, status, error) {
Ember.run(function() {
reject(xhr.responseJSON || xhr.responseText);
});
});
});
}
});
I am using ember simple auth 1.0.0. Anybody have a working solution to this problem?
If you're using the DataAdapterMixin that will automatically handle all 401 response to Ember Data requests and invalidate the session if it gets one. If you're making your own AJAX requests you'd have to handle these responses yourself.
Automatic authorization of all requests as well as automatic response handling was removed in 1.0.0 as it lead to a lot of problems with global state and made the whole library much harder to reason about.
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 need a cross-domain user login request instance, please help me, thank you！！
My code
Ext.data.JsonP.request({
url: 'http://25.30.2.3:8080/newvbo/applyaction!longin',
params: {
username:'13881901678',
password:'111111',
},
success: function(response, opts) {
alert('1');
},
failure: function(response, opts) {
alert('2');
}
});
My question is, I not receive the server returns the value, I wrong?
You can Try this
Ext.Ajax.request({
method:'GET',
contentType:'application/json; charset=utf-8',
dataType:'json',
url:'http://........Login',
disableCaching: false,
withCredentials: true,
useDefaultXhrHeader: false,
callbackKey: 'callback',
params: {
EmailId:Ext.getCmp('usernametwoway').getValue(),
Password:Ext.getCmp('loginpasswordtwoway').getValue(),
},
success:function(response)
{
console.log(response);
var res = response.responseText;
var jsonarr = Ext.decode(response.responseText);
console.log(jsonarr);
var myres = jsonarr[0].Result;
console.log(myres);
switch(myres)
{
case '1':
console.log("Registration response is successfully");
Ext.Viewport.setActiveItem({xtype:'passengerdetailstwoway'});
break;
case '0':
console.log("Failed");
Ext.Msg.alert("Error","Login Failed",Ext.emptyFn);
break;
Based on the responce you can Specify the Switch case..
Hi #jesse you can try for cross-domain something like this,
Ext.Ajax.request({
url: 'your_url_path',
timeout: 90000,
params: {
withCredentials: true,
useDefaultXhrHeader: false,
username:'13881901678',
password:'111111',
},
success: function(response, o) {
if(response != '') {
alert('1')
}
},
failure: function(response, o) {
alert('2')
}
})
For cross-domain you need put withCredentials: true and useDefaultXhrHeader: false.
I hope help you.
I would like to suggest you a different approach because sending login credentials as GET parameter to remote server over http is not a good idea, instead you should use POST method over HTTPS. Now you would think JSONP doesn't support POST so how can I do this, but if you are going to install your app on Phone or iPad it would do remote call from browser without using JsonP, which means you can use normal AJAX proxy to do whatever you want. Check this out:
How to use json proxy to access remote services during development
Which means this should work:
var obj = new Object();
obj.userId = username;
obj.password = password;
var data = Ext.JSON.encode(obj);
Ext.Ajax.request({
url : 'https://login_url',
method : "POST",
headers: {
'Content-Type': 'application/json'
},
params : data,
useDefaultXhrHeader : false,
withCredentials: true,
success : function(response) {
},
failure : function(response) {
}
});
