java - 堆栈交换 oauth 响应不可读

Question

您好，我正在尝试建立一个基于 Java 和 apache Oltu 库的授权 oauth 客户端，用于堆栈交换 api。

我收到的响应在控制台中打印时看起来像这样 u��n�0����"+���tU��l��*k��l����{B��M����s�h�W�#��带Wj@ٹ�F*P� ����������N��р���=ѹ�\k��

在浏览器中，响应以可读格式很好地打印。我的问题与 Http request to stackexchange api returns unreadable json 但正如已接受的答案所示，响应流是 gzip 压缩的 JSON。当我尝试解压缩响应时，我的程序显示“不是 GZIP 格式”格式。我尝试了以下操作: 新的GZIPInputStream(响应)

如果我将响应转换为十六进制，我会得到以下结果:

所以我现在的问题是我无法直接读取JSON并且无法使用GZIP解压缩它。我现在可以做什么来处理数据？有任何想法吗 ？感谢您的时间。

到目前为止，我编写了一个像这样的直接 http 调用//HTTP GET 请求 private String sendGet(String accessToken) 抛出异常 {

    String url = "https://api.stackexchange.com/2.2/me?site=stackoverflow&key="key"((&access_token=";
    url = url + accessToken;
    URL obj = new URL(url);
    HttpURLConnection con = (HttpURLConnection) obj.openConnection();
    con.setRequestMethod("GET");      
    int responseCode = con.getResponseCode();
    if(responseCode == 200){
        System.out.println("\nSending 'GET' request to URL : " + url);
        System.out.println("Response Code : " + responseCode);
        //System.out.println(con.getContentEncoding());
        //System.out.println(con.getContentType());

        GZIPInputStream gp = new GZIPInputStream(con.getInputStream());
        BufferedReader br = new BufferedReader(new InputStreamReader(gp));

        StringBuffer response = new StringBuffer();
        String line;
        while ((line = br.readLine()) != null) {
            response.append(line);
        }

        br.close();

        System.out.println(response.toString());
        return response.toString();
    }
    else{
        return null;
    }
