如何調用訪問令牌的Yelp API？

我試圖發送一個POST請求Yelp的API使用這些指令來獲得訪問令牌：https://www.yelp.com/developers/documentation/v3/get_started 如何調用訪問令牌的Yelp API？

但是，下面的代碼不打印任何東西到控制檯。我不確定問題所在，或者我已經正確設置了POST請求。我的代碼有什麼問題？ :(

foodfinder.html：

<!DOCTYPE html> 
<html lang="en"> 
<head> 

    <script src="./public/foodfinder.js"></script> 
    <meta charset="UTF-8"> 
    <title>Food Finder</title> 
    </head> 

    <body> 

    Hello world 


    </body> 
    </html>

foodfinder.js：

$(function() { 

var API_HOST = "api.yelp.com"; 
var SEARCH_PATH = "/v3/businesses/search"; 
var BUSINESS_PATH = "/v3/businesses/"; 
var TOKEN_PATH = "/oauth2/token"; 
var GRANT_TYPE = "client_credentials"; 

var CLIENT_ID = "abc"; // dummy id for stackoverflow purposes 
var CLIENT_SECRET = "xyz"; // dummy secret for stackoverflow purposes 

var SEARCH_TERM = "food"; 
var SEARCH_RADIUS = 500;  // radius is in meters 
var SORT_BY = "distance"; 


$.ajax(API_HOST + TOKEN_PATH, { 
    type: "POST", 
    data: { 
     grant_type: GRANT_TYPE, 
     client_id: CLIENT_ID, 
     client_secret: CLIENT_SECRET 
    }, 
    contentType: "application/x-www-form-urlencoded", 
    dataType: "json", 
    success: function (data) { 
     console.log(data); 

    }, 
    error: function() { 
     console.log("post call error"); 
    } 


}) 
});

也許你需要的HTTPS在主機變量，像

var API_HOST = "https://api.yelp.com";

當我在沒有https的情況下測試呼叫，我收到一個錯誤： {"error": {"description": "/oauth2/token", "code": "VALIDATION_ERROR"}}
