无法连接到shipstation的api

Question

我在从shipstation的api获取数据时遇到问题。我可以看到数据是在网络和预览选项卡下提取的。但是当我尝试将“数据”传递到控制台时，我收到一条解析器错误消息。任何帮助，将不胜感激。谢谢！

var URL = 'http://ssapi.shipstation.com/carriers/';

        $.ajax({
           type: "GET",
           url: URL,
           contentType: "application/json; charset=\"utf-8\"",
           xhrFields: {withCredentials: true},
           dataType: 'json', 
           success: function (data) {

           var output = JSON.parse(data);

           console.log('success ' + data + " parsed: " + output);

           $('#results').append('<p>' + output + '</p>');
           },

          // Display errors if any.
          error: function(req, err){ console.log('Error Type: ' + err); }

          });
