我使用以下代码从服务器获取这些数据：

    public String readJSONFeed(String URL) {
    StringBuilder stringBuilder = new StringBuilder();
    HttpClient httpClient = new DefaultHttpClient();
    HttpGet httpGet = new HttpGet(URL);
    try {
        HttpResponse response = httpClient.execute(httpGet);
        StatusLine statusLine = response.getStatusLine();
        int statusCode = statusLine.getStatusCode();
        if (statusCode == 200) {
            HttpEntity entity = response.getEntity();
            InputStream inputStream = entity.getContent();
            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(inputStream, "UTF-8"));
            String line;
            while ((line = reader.readLine()) != null) {
                stringBuilder.append(line);
            }
            inputStream.close();
        } else {
            Log.d("JSON", "Failed to download file");
        }
    } catch (Exception e) {
        Log.d("readJSONFeed", e.getLocalizedMessage());
    }        
    return stringBuilder.toString();
}

当我尝试解析字符串时

JSONObject jsonObject = new JSONObject(result);

，我得到一个异常，很可能是因为 JSON 无效。如果我尝试像这样手动替换 unicode 字符，它会完美运行：

  • \u000a 替换为新行
  • \" 仅替换为 "
  • 第一个和最后一个 " 被删除

我将如何解析这些数据？

您有一个 JSON 字符串，它本身以字符串文字格式包装。不是 100% 确定包装字符串格式是什么，因为有许多格式使用\u和\"转义 - 您应该在您调用的服务上获取任何文档，以尝试弄清楚它应该是什么。将 Web 服务返回结果包装成这样的字符串文字格式似乎很奇怪，也没有必要。

一种可能性是 Java 字符串文字；在这种情况下，请参阅Apache 的 StringEscapeUtils 中的unescapeJava。

然而，最有可能的是 JSON 字符串文字 - 即双 JSON 编码。在这种情况下，您必须先对字符串进行一次 JSON 解码，然后再查看其中的嵌套 JSON 结构。

但是，假设您使用的是 org.json，则没有直接的JSONString解析器可以与JSONObjectandJSONArray解析器一起使用。但是，您始终可以将字符串包装在其中一个可以理解的结构中，例如：

String unwrapped= new JSONArray("["+result+"]").get(0);
JSONObject o= new JSONObject(unwrapped);
