Problem is when i try to use this code to get the log from tmi.twitch.tv api using url: http://tmi.twitch.tv/hosts?include_logins=1&target=70219146 i get Systax Error Unexpected Token. The code is:
$(document).ready(function() {
$.getJSON("http://tmi.twitch.tv/hosts?include_logins=1&target=70219146&callback=?", function (data) {
console.log(data.hosts)
});
})
I can get the data using php and json array like this:
$json_array = json_decode(file_get_contents('http://tmi.twitch.tv/hosts?include_logins=1&target=70219146'), true);
echo $json_array['hosts']['0']['host_login']."</br>";
But isnt there a way to use do this in html? thanks
You are trying to request regular JSON as JSONp (&callback=? activates jQuery's JSONp request method) which actually embeds the response into a <script> to execute it. However, the twitch API still returns JSON which is not valid JavaScript. Unless there is a way to make tmi.twitch.tv return valid JSONp, there is no way to do this directly from JavaScript unless you use a proxy like http://crossorigin.me/.

I am trying to load some images from a file on a server to display on a list. I get 404 not found error
after asking in forums, I get that the request URL is wrong, it looks inside the localhost not inside the json file.
https://filehost.net/db54d37849f75ddd
in the code I have a service which returns a response. I use that response in a controller and to the view. I get other information but no images
if anybody has a solution that would be really great.
please attach also some code, in this way it is easier to help you. About the problem, do have correct form of $http GET request? I mean does your get request points to correct address on server? something like this
`
// Simple GET request example:
$http({
method: 'GET',
url: '/someUrl'
}).then(function successCallback(response) {
// this callback will be called asynchronously
// when the response is available
}, function errorCallback(response) {
// called asynchronously if an error occurs
// or server returns response with an error status.
});

I have a primitive problem, I'm trying to send a string message in the servlet inside doGet function, then catch this message in the HTML function using JSON? Any help?
First, if you insert ur code in doGet, you need in ajax to do a GET request.
You need to give an url to your servlet in the web inf file.
Then you need a javascript file (linked in your html). This js file would have smt like this.
$(document).ready(function(){
$.get( "urlInWebInf", function( data ) {
console.log(data);
});
)}
It should display your json in the console.
Hope it helps!
So, I am stuck here and feel like banging my head.
My problem is I query a database by ajax and returned its response in json form. Now I have this response in the form of javascript variable but I want to pass it to a php variable for further use.
How can I do that ??
function getJson(url){
return JSON.parse($.ajax({
type:'GET',
url: url,
dataType:'json',
global:false,
async:false,
success: function(data){
return data;
}
}).responseText);
}
Here how do I pass data to php ??
FIrstly I gave you -1 for not learning the basics!
- You can send client values to server (php) as querystring
example: /server_link?json=JSON_VAL
(not recommended for whole json string)
- Send it as post body (look for jquery ajax post) and parse it with php json library.
- if you have just single level json ({name:'John', sname:'Smith)} you can send it to php server(as mentioned before ajax post) and read as request variable in php ($_POST, $_...).
As I never programmed in php you'll have to do it you're self.
A again: LEARN THE BASICS (client side, server side, post, get,...).
Need to fetch the build values from apache.org. So i am using their api
https://builds.apache.org/api/json
I tried angularjs $http.jsonp but not able to fetch the data.
In chrome console under network json api is getting loaded but the data is not getting returned instead it is throwing the response as error.
app.controller("jsoncontroller",function($scope,$http){
var url='https://builds.apache.org/api/json';
$http.jsonp(url).success(function(data){
console.log('success');
})
.error(function () {
console.log('error')
});
});
Getting the error as
Uncaught SyntaxError: Unexpected token :
error
As per the jsonp angular docs, you must append JSON_CALLBACK to the URL: https://builds.apache.org/api/json?jsonp=JSON_CALLBACK
However, that URL doesn't work because even when the callback parameter is specified, the server still sends back a content-type of application/json, instead of the expected application/javascript. This causes it to be parsed (evidently) by the json parser instead of the javascript callback needed for JSONP to work. I'm not versed enough in JSONP or Angular to know who is it fault here.
I've made a fiddle with this working with another URL.
[Update]: The apache build server appears to use Jenkins, which has disable JSONP from the remote API. You can verify this yourself by trying to hit their jsonp endpoint, which returns a 403. You'll have to use another endpoint, no way I can see around this.
I cant manage to loop through my json that i have setup at this url i just keep getting the following error Uncaught SyntaxError: Unexpected token ILLEGAL
here is my json http://example.com/api/?email=info#example.co.uk&format=json
i am trying to pull it in from the following code.
//json
var json_feed = 'http://example.com/api/?email=info#example.co.uk&format=json&callback=?';
$.getJSON(json_feed, function(json) {
console.log(json);
});
Where am i going wrong can someone advise.
Manage to get it to work with the following..
php
header('content-type: application/json; charset=utf-8');
echo json_encode($buckets);
jquery
$.ajax({
url: 'http://example.com/api/?email=info#example.co.uk&format=json',
success: function(data) {
console.log(data);
}
});
The url you have shown doesn't returns JSON but not JSONP. Due to the same origin policy restriction you cannot send cross domain AJAX calls unless the server supports JSONP. You have added the callback=? parameter to the url which is OK from the client side perspective as jQuery will send it, but the server seems to completely ignore it and it returns JSON instead of wrapping this JSON into the callback passed as parameter (which is JSONP).
You should probably contact the authors of the site you are trying to access or read the documentation of the API they are exposing (if any) to see if it supports JSONP.
