这是我的卷发：

curl -X POST "http://bc.itg.ro:1239/api/ro/products" -H "accept: application/json" -H "X-Accept-Token: 7b030f02cce38a84d35122b5f353faq1" -H "Content-Type: application/json" -d "{ \"language_id\": 2, \"currency_id\": 4, \"filters\": { \"category_ids\": [ 56 ] }, \"current_page\": 1, \"limit\": 20}"

我想调用api以获取JSON

let xhr = new XMLHttpRequest();

          xhr.onreadystatechange = function() {
            //  Check if request is completed
            if (xhr.readyState == XMLHttpRequest.DONE) {
              //    Do what needs to be done here
              console.log(xhr.response);
              }
          }

          // Set the request URL and request method
          xhr.open("POST", "http://bc.itg.ro:1239/api/ro/products");

          // Set the `Content-Type` Request header
          xhr.setRequestHeader("accept", "application/json");
          xhr.setRequestHeader("X-Accept-Token", "7b030f02cce38a84d35122b5f353faq1");
          xhr.setRequestHeader("Content-Type", "application/json");

          // Send the requst with Data
          xhr.send('{\"language_id\": 2, \"currency_id\": 4, \"filters\": { \"category_ids\": [ 56 ] }, \"current_page\": 1, \"limit\": 20}');
      }
