Question

我有一个方法（如下）。我想要它返回什么＆＃39; str.trim（）＆＃39;产生。＆＃39; str.trim（）＆＃39;产生低于JSON。问题是我该如何归还？目前，我正在返回方法本身，getData()这不好。此外，返回类型需要为String[]，因为我需要将此返回值传递给Object。

str.trim()生成此内容：{ "a", "b", "c" }

----------------------方法------------------------

      private String[] getData() {

    try {
        URL url = new URL("https://localhost:8443/");
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("GET");
        conn.setRequestProperty("Accept", "application/json");

        if (conn.getResponseCode() != 200) {
            throw new RuntimeException("Failed : HTTP error code : "
                    + conn.getResponseCode());
        }

        BufferedReader br = new BufferedReader(new InputStreamReader(
            (conn.getInputStream())));

        String output;
        StringBuilder sb = new StringBuilder();
        //System.out.println("Output from Server .... \n");
        while ((output = br.readLine()) != null) {
            //System.out.println(output);
            sb.append(output + "");


        }
        String content = sb.toString();
        String str = content.replace("[", "{").replace("]", "}");
        //System.out.println(content.replace("[", "{").replace("]", "}"));
        System.out.println(str.trim());



        conn.disconnect();


      } catch (MalformedURLException e) {

        e.printStackTrace();

      } catch (IOException e) {

        e.printStackTrace();

      }
    return getData();

我懂了!!解决。

我需要在顶部分配一个新变量。将它分配给str.split（）;

现在有效!!

如何在String []类型中返回{＆＃34; a＆＃34;，＆＃34; b＆＃34;，＆＃34; c＆＃34; ......}的字符串
