IMDB-API - 在 while 循环中读取响应不读取超过一行

Question

我正在从 Java 代码调用 IMDB-Api。它成功连接到 IMDB api 并读取数据，但由于某种原因，它读取的内容不超过一行。我在“aline”变量中看到了整个响应。但是 while 循环只执行一次..我想知道为什么？

         String urltext = "https://imdb-api.com/API/AdvancedSearch/keyxxx/?genres=action,adventure";
       try {
        URL aurl = new URL(urltext);

        aconnection = (HttpURLConnection)aurl.openConnection();

        aconnection.setRequestMethod("GET");

        aconnection.setDoInput(true);


        InputStream astream = aconnection.getInputStream();

        BufferedReader areader = new BufferedReader(new InputStreamReader(astream));

        StringBuilder aresponse = new StringBuilder();

        String aline = null;
        
        while((aline = areader.readLine())!=null){
             //I see the entire response in 'aline' variable. But the while gets executed only 
             once.. I wonder why?
            aresponse.append(aline);
            aresponse.append("/r");
        }
        areader.close();
        String aresult = aresponse.toString();
        System.out.println(aresult);


        JSONObject aobject = new JSONObject(aresult);

        String ratings= aobject.getString("imDb");
    }catch (MalformedURLException e){
        System.out.println("Malformed exception");
    }catch (IOException e) {
        System.out.println("IO exception");
    }
    catch(Exception e){
        e.printStackTrace();
    }
}
