I am trying to make an AJAX call in angularjs 1.3.15 to a cross-site domain. I have a standard AJAX call working now but would like to use angular's $http config element instead.
my AJAX call now:
var responsePromise = $.ajax({url:"https://some-address.com",
type: "GET",
dataType: "json",
xhrFields: {withCredentials:true},
crossDomain: true});
//my success and error functions
what I tried with $http(config)
var repsonsePromise = $http.get('/some-address.com',{reponseType:{json},
withCredentials:{'true'}});
//my .success and .error functions
I have looked at the $http.get service here
What do I put for the crossDomain: true argument or is could someone tell me the equivalent syntax of my working AJAX call in order for this to work? Your help is greatly appreciated, thank you in advanced.
Try this:
app.config(function($httpProvider) {
$httpProvider.defaults.useXDomain = true;
delete $httpProvider.defaults.headers.common['X-Requested-With'];
});

I'm trying to use the google chart api in an XPages application.
I'm using the code example given by the documentation : https://developers.google.com/chart/interactive/docs/php_example#exampleusingphphtml-file
I have to replace the call to the php page by a call to an LS agent.
var jsonData = $.ajax({
url: "getData.php",
dataType: "json",
async: false
}).responseText;
So my code goes to :
var jsonData = $.ajax({
url: "http://server/database/agent?openagent",
dataType: "json",
async: false
}).responseText;
On my local domino server, it works fine.
On the production domino server, I get nothing. The chart is not drawn. After debugging the js client side, it seems the ajax call is expecting an authentification even if I had to log in before.
The anonymous access is not allowed on both servers.
The security level seems to be same on both environments
Any help will be welcome (or any other way to proceed if I'm wrong).
Thank you
If you are able to draw the google chart in your local server, but not in production server, this means it is your server issue.
You can add authentication header in your jquery ajax call to make authenticated ajax request
$.ajax({
headers: {
"Authorization": "Bearer <TOKEN HERE>"
}
})
You can also send username and password in jquery ajax call, to make authenticated request. Here is the sample code from the link
$.ajax({
type: 'GET',
url: 'url',
dataType: 'json',
//whatever you need
beforeSend: function (xhr) {
xhr.setRequestHeader('Authorization', make_base_auth(user, password));
},
success: function () {});
});
function make_base_auth(user, password) {
var tok = user + ':' + password;
var hash = btoa(tok);
return 'Basic ' + hash;
}
at the end, I tried to run the ajax request through dojo instead of Jquery.
My codes became this one :
var jsonData = dojo.xhrGet({
url: "http://server/database/agent?openagent",
handleAs:"json",
...
})
I did no changes at the security level or anything else.
I do not understand why the jquery syntax is not working as well the dojo syntax.
anyway, it is working now.
Many thanks to all for your suggestions
I am near a solution to get json data, just get the error :
SyntaxError: missing ; before statement
My json data look like this :
{"custom1":"","dateOfBirth":null,"custom2":"","custom3":"","custom4":"","custom5":""}
I am using jsonp. this solved my problem with CORS (Cross-origin request blocked)
In the debugger i can see the data in the NET.
How close i am?
Som get me the last push to resolve my problem??
<script type="text/javascript">
function getdata() {
$.ajax({
type: 'GET',
url: 'http://myurl/api/getUser/22?_key=123456789',
dataType: 'jsonp',
//contentType: "application/jsonp",
success: function (data) {
$('#badge').append(result);
}
});
}
You have to set your ajax response type to jsonp instead of json.
Like
dataType: 'jsonp'
You can read more about it in jquery docs on $.ajax. Also as I can see, the result variable that you are trying to append in the success callback is not declared & inititalized anywhere in the code you have provided.
I use this code to store and retrieve ajax data via http://openkeyval.org/
$.ajax({ /* send data */
url: "http://api.openkeyval.org/store/",
data: "test-key-data=" + JSON.stringify([123,456]),
dataType: "jsonp",
success: function(data){
console.log(data);
}
});
$.ajax({ /* retrieve data */
url: "http://api.openkeyval.org/test-key-data",
dataType: "jsonp",
success: function(data){
console.log(data);
}
});
everything work fine in Chrome javascript console but in userscript I get error like this
Uncaught ReferenceError: jQuery110208458673823624849_1375932537303 is
not defined
I try to use GM_xmlhttpRequest to retrieve data like this
GM_xmlhttpRequest({
method: "GET",
url: "http://api.openkeyval.org/test-key-data",
onload: function(response) {
console.log(response.responseText);
}
});
but it seem like openkeyval doesn't accept data via POST/GET method and log result was like when you access it directly from url of browser like this
{"error":"not_found","documentation_url":"http://openkeyval.org/"}
I include jQuery and it work fine with this code
// #require http://code.jquery.com/jquery-latest.min.js
I try to use Greasemonkey/jQuery XHR bridge with out change other code by like this
// #require http://courses.ischool.berkeley.edu/i290-4/f09/resources/gm_jq_xhr.js
and try use openkeyval official javascript library with code like this
// #require http://cdn.openkeyval.org/statics/openkeyval.packed.js
and retrieve data with code like this
var ourCallback = function(value, key) {
console('The value of ' + key ' + is ' + value);
};
window.remoteStorage.getItem('test-key-data', ourCallback);
still got error ERROR: Unexpected string
Please help, I mess with it more than 10 hours. Thank you so much.
It look like $.ajax always trigger error event function
but GM_xmlhttpRequest can retrieve mistype data, so I try looking for dataType: "jsonp" in GM_xmlhttpRequest and I got that jsonp header content-type is "application/javascript" OR "application/json" and the first one work well.
my new code for retrieve data look like this
GM_xmlhttpRequest({
method: "GET",
url: "http://api.openkeyval.org/test-key-data?nocache=" + new Date(),
headers: {
"Content-Type": "application/javascript"
},
onload: function(response) {
console.log(response.responseText);
}
});
and retrieve data using $.ajax even it always trigger error event function but it still send data.
I try both content-type on GM_xmlhttpRequest and still not work.
my code to store data look like this
$.ajax({ /* send data */
url: "http://api.openkeyval.org/store/",
data: "test-key-data=" + JSON.stringify(myVarObject),
dataType: "jsonp"
});
Add this into $.ajax({...})
crossDomain: true;
It is because by default cross domain ability is disabled. See http://api.jquery.com/jQuery.ajax/
EDIT:
Sometimes there will be a issue with different charset between local script and remote script. Try using:
scriptCharset: "utf-8";
Also look at JQuery AJAX is not sending UTF-8 to my server, only in IE
Elaborating my comment
The reference is to the callback function generated by jquery.
It Sounds to me the way you invoke your userscript unloads the jquery functions before the callback is executed.
Perhaps you use a link and forgot the preventDefault?
If you ajax and have
$("#linkid").on("click"
or
$("#formid").on("submit"
it is MANDATORY to continue like this:
,function(e) {
e.preventDefault();
Otherwise the link is followed or the form is submitted which may not have any visible effect, but the asynchronous scripts have been (partially) unloaded unless the form and link has a target other than the current window
The call looks something like so
$.ajax({
url: url,
crossDomain: true,
dataType: 'jsonp',
success: function(){console.log('success');}
})
From the server code it something like so
string data = callback + "(" jsonData + ")";
send("application/javascript",data);
The jsonData is valid, which I'm pretty sure of. I have tested it out on many json validators online. I've also tried switching the content-type from application/javascript to application/json in the server code but it does no difference.
The only way I've got this to work is override the callback function sent my jquery, and have it so that instead of calling jquery success function, it calls my own global function. And here is the code for that workaround
$.ajax({
url: url,
crossDomain: true,
dataType: "jsonp",
jsonpCallback: "onMyDataReceived"
})
function onMyDataReceived(jsonData){ doStuff(jsonData ); }
but I feel like this is more of a hack instead of having it naturally flow from $.ajax.sucess function. Any help on why the first code snippet would error out?
I am really not sure why the first snippet didn't work, but trying the following
$.getJSON(url+"&callback=?",function(data){ console.log(data);})
worked in my case.
Supposing I have the following code which returns a Javascript object which I can read in Firebug's console:
FB.api('/me',function(apiresponse){
console.log(apiresponse);
});
How can I then use the data from apiresponse in an Ajax request on the same page?
Currently my Ajax request looks as follows:
$.ajax({
// CodeIgniter URL
url: "<?=site_url?>('login/add_fb_users'); ?>",
type: 'POST',
data: apiresponse,
success: function(data) {
alert(data);
}
});
I know very little about Javascript, but reading around the subject leads me to think I have to convert the Javascript object to a JSON string. Is that correct? Am I on the right track?
You could put your AJAX call inside the handler for the API call like below..
FB.api('/me', function(apiresponse){
console.log(apiresponse);
$.ajax({
// CodeIgniter URL
url: "<?=site_url?>('login/add_fb_users'); ?>",
type: 'POST',
data: apiresponse,
success: function(data) {
alert(data);
}
});
});
one possible way:
define a global variable in your javascript, e.g. var myVar1;
set apireponse to the global variable in your FB.api callback (i.e. where u call console.log)
reference the var myVar1 in your ajax fcn.
