Question

相关代码如下所示：

            HttpURLConnection conn = (HttpURLConnection) new URL("https://api.branch.io/v1/url").openConnection();
 conn.setDoOutput(true);
            conn.setUseCaches(false);
            conn.setFixedLengthStreamingMode(bytes.length);
            conn.setRequestMethod("POST");

            conn.setRequestProperty("Content-Type", "application/json");
            out = conn.getOutputStream();

            out.write(bytes);
            in = conn.getInputStream();

            BufferedReader reader =new BufferedReader(new InputStreamReader(in));
