in Ajax, how to write "headers" for multiple condition?

as a beginner, I have some problems in using Ajax (with Discogs API) .. to get a discogs request token, discogs is saying
Include the following headers with your request:
Content-Type: application/x-www-form-urlencoded
Authorization:
OAuth oauth_consumer_key="your_consumer_key",
oauth_nonce="random_string_or_timestamp",
oauth_signature="your_consumer_secret&",
oauth_signature_method="PLAINTEXT",
oauth_timestamp="current_timestamp",
oauth_callback="your_callback"
User-Agent: some_user_agent
https://www.discogs.com/developers#page:authentication,header:authentication-discogs-auth-flow
but, how to write this header?
below is my trying code, but I know this is not proper.
$.ajax({
type: "GET",
url: "https://api.discogs.com/oauth/request_token",
dataType: 'jsonp',
headers: {
ContentType: "application/x-www-form-urlencoded",
Authorization: OAuth oauth_consumer_key="your_consumer_key",
oauth_nonce="random_string_or_timestamp",
oauth_signature="your_consumer_secret&",
oauth_signature_method="PLAINTEXT",
oauth_timestamp="current_timestamp",
oauth_callback="your_callback",
UserAgent: some_user_agent,
}
success: function (data) {
console.log(data);
document.getElementById("content").innerHTML += "<br>" + `${data}`;
},
error: function (error) {
console.log(error);
}
});

You said:
dataType: 'jsonp',
It isn't possible to specify headers for JSONP requests.
The API can't be using JSONP. Set the dataType to the format they are using.
The documentation says:
When you create a new application, you’ll be granted a Consumer Key and Consumer Secret, which you can plug into your application and start making authenticated requests. It’s important that you don’t disclose the Consumer Secret to anyone.
Putting those in your client-side code will disclose them to all your visitors.
The request to that end point should be made from server-side code.

Algolia analytics API cannot be called from frontend application?

Is it possible to call analytics API from javascript with jQuery?
I've been struggling with this for couple of days with no luck. I tried using CORS wich is sending OPTIONS request first which is rejected (405 error). Also tried with jsonp - but from what I read it has to be configured on server side?
Sample code (nothing fancy):
$.ajax({
url: 'https://analytics.algolia.com/1/searches/test/popular',
method: 'GET',
beforeSend: (xhr) => {
xhr.setRequestHeader('X-Algolia-Application-Id', 'sample');
xhr.setRequestHeader('X-Algolia-API-Key', 'sample');
},
success: (response) => {
console.log(response);
}
});
Also tried with crossOrigin: true, and dataType: 'jsonp'.

This API has not been designed to be called from the frontend (and therefore doesn't support CORS). You will need to build a proxy through your backend.

Possible to get Asana tasks through JSON-P and Asana Connect?

Is it possible to connect to ASANA without a backend?
We have a secure folder on a webserver where we'd like to retrieve a task list of a project using only Javascript. Is that possible?
I saw some news from Asana that they support JSON-P through Asana Connect, but it's a bit unclear on how you could set this up from the documentation. Is there any examples available that I haven't found? Or have anyone succesfully set this up earlier?

The preferred way to do this is using CORS (added November 2013) - see this gist for an example of how you can use it. If you're unfamiliar with CORS, it stands for Cross-Origin Resource Sharing, and allows you to make cross-domain requests, given that the headers of the client and server match appropriately.

Incase anyone is already using Jquery (like I am) you can use the following code to do the same as the example from #agnoster.
$.ajax({
url : 'https://app.asana.com/api/1.0/users/me',
dataType : 'json',
type: 'GET',
beforeSend : function(xhr) {
xhr.setRequestHeader('Authorization', 'Basic ' + btoa(api_key + ":"));
}
}).done(function(response) {
console.log(response.data);
});
And if you need to POST/PUT you can use jQuery like this:
$.ajax({
url : https://app.asana.com/api/1.0/tasks/taskid',
dataType : 'json',
type: 'PUT',
data: { "completed": true },
beforeSend : function(xhr) {
xhr.setRequestHeader('Authorization', 'Basic ' + btoa(api_key + ":"));
}
});
PS! you'll not be able to get this working for IE9 as it does not support sending headers (so the xhr.setRequestHeader() won't work)

Uncaught SyntaxError: Unexpected token : ajax call

So I'm trying to query the below json feed, however I keep getting the error in the topic.
I've searched around this site for possible answers however none that I've come across have worked so far. Commented out datatype and jsonp, jsonpCallback isnt it either, either is data, I've made sure that it validats via http://jsonformatter.curiousconcept.com/ and it does. I really dont know.
$.ajax({
type: 'GET',
url: 'http://raidbots.com/json/playerdata/us/mannoroth/usiris',
cache:true,
dataType: 'jsonp',
data: {
format: 'json',
},
success: ranks,
jsonpCallback:'callbackName',
error: function(data) { console.log(data); },
jsonp: false,
});
function callbackName(data){
console.log("jsonpCallback");
}
var ranks = function(data) {
console.log(data);
}
Thank you

The error is in your JSONp data because it's just JSON and not JSONp. JSONp requires the document to be valid JavaScript containing a function call.
If they don't support jsonp you need to use a proxy script (e.g. a php script on your server that retrieves the document) or ask them to send CORS headers so you can use a normal non-JSONp AJAX call to retrieve the data directly.

Creating an API in yii for cross domain communication

I am planning to create a Restful API in yii for cross domain communication. As what I have researched, cross domain communication can only be done via jsonp and my implementation is as follows:
UsersController:: actionCrossDomain
public function actionCrossDomain(){
$this->layout=false;
$data['data']['User']['name']= 'Johny';
$this->_sendResponse(200, CJSON::encode($data),'application/json');
}
UsersController::_sendResponse methdod it is the same as you can see in :Click here
On another server that i configured using virtual host, I am invoking the above method via ajax:
$( document ).ready(function() {
$.ajax({
type: "POST",
dataType: "jsonp",
url:'http:'http//uxaserver.local/alpha2/app/users/crossDomain' ,
data: null,
processData: false,
crossDomain: true,
contentType: "application/json",
success: function (data) {
console.log("done");
},
error: function (request, status, error) {
console.log(request);
}
});
});
The issue is my firebug is is complaining that : SyntaxError: invalid label
My requirement is such because I am helping my client's to do some customized analytic to his other websites and I need to put a script in his web pages of different domains so that the analytic data is recorded in the main server. I understand that I need to use the rest interface to communicate thus I am taking this approach. I am not sure if I have taken the right approach and please advice. I want to make it in a way where a client has an api key and can communicate with the api provided by me.
Is there any other approach to do this? Rather than jsonp?

As i see this string contents error
url:'http:'http//uxaserver.local/alpha2_uxarmy/app/users/crossDomain' ,
Should be
url:'http//uxaserver.local/alpha2_uxarmy/app/users/crossDomain' ,
