javascript - Using POST and GET to Exchange Data Through Endpoints -

-

i'm attempting build web app using spotify's web api however, find tutorial lacking. way works data requested using post , functionality , sent using json. seems easy enough, want information artist? call https://api.spotify.com/v1/artists/0oduwj0sbjdrqhygguxecf , nice json document information requested artist.

the problem don't know how make call. jquery has , post methods both "data" parameters i'm not sure on syntax necessary, when comes exchanging authorization code access token. if visit spotify's authorization guide , scroll step 4 of authorization code flow can see need make post call https://accounts.spotify.com/api/token. call must have 3 request body parameters , 1 header parameter , upon succession json file appropriate data in response body.

my question how make post , calls have body parameters , header parameters , how extract json data response body after successful call?

as can see code examples & libraries , jsfiddle, getuserdata request nothing simple ajax call, contains url , headers object (which contains prefix string concatenated accesstoken) parameters:

    function getuserdata(accesstoken) {         return $.ajax({             url: 'https://api.spotify.com/v1/me',             headers: {                'authorization': 'bearer ' + accesstoken             }         });     }

generally, when need pass parameters in $.ajax call, shown above, or construct object first , include this:

yourobj = {    url: "your url here",    param2: "param val 2",    param3: "param val 3",    ... }  $.ajax(yourobj).done(function(data){    //do returned data here, e.g.    console.log("data: ", data); });

this approach can useful if parameters dependent on other values not readily avalable.

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
