我正在用NodeJs发出一个HTTPS POST请求，我得到了一个本应在JSON中的奇怪的缓冲区。

下面是我的代码：

       var options = {
            url: someURL,
            host: "SomeApi.com",
            method: 'POST',
            encoding: null,
            gzip: true,
            headers: {
                'Accept': 'application/json, text/json, text/x-json, text/javascript, text/xml, application/xml',
                'User-Agent': 'RestSharp/105.2.3.0',
                'Accept-Encoding': 'gzip, deflate',
                'Content-Length': '0'
            },
        }

        var body = "";
        https.get(options, (response) => {
            response.on('data', (chunk) => {
                body += chunk;
            });
            response.on('end', () => {
                //var data = JSON.parse(body);
                console.log(response);
                //gunzipJSON(response)
            });

        });

这就是我要得到的：

这是我想要返回的JSON代码的长编码表示吗？如果是这样，我该如何解码呢？

如果这是一个补救性的问题，我提前道歉。我是NodeJs的新手，正在提出请求，感谢您的帮助！
