在Java中解析JSON响应以提取值 [英] Parsing JSON Response in java to extract values

问题描述

我想做的是得到响应，但不知道如何从中提取值.

What I'm trying to do is get a response, but don't know how to extract the values from it.

实际响应如下:

[
   "SUCCESS",
   [   [
      "Karachi",
      ["کراچی"],
      [],
            {
         "candidate_type": [0],
         "is_confident": [true]
      }
   ]]
]

我需要从中提取urdu文本

    String text = "Karachi";            
    String url = "https://inputtools.google.com/request";       
    try {           
         final HttpClient client = new HttpClient();
            final PostMethod method = new PostMethod(url);
            method.setParameter("text", text);
            method.setParameter("itc", "ur-t-i0-und");
            method.setParameter("num", "1");
            method.setParameter("cp", "0");
            method.setParameter("cs", "1");
            method.setParameter("ie", "utf-8");     
            client.executeMethod(method);               
            BufferedReader strResponse =  new BufferedReader(new InputStreamReader(method.getResponseBodyAsStream(),"UTF-8"));
            Object jObj =   (Object) JSON.parse(strResponse);

推荐答案

尝试一下(您的缓冲区读取器可能有多行):

Try this (Your buffer reader may have more than one line):

StringBuilder yourJsonString= new StringBuilder();
String line;
while ((line = strResponse.readLine()) != null) {
      yourJsonString.append(line);
}
JSONArray jsonObject = new JSONArray(yourJsonString.toString());
//retrieve the second element of json array
JSONArray secondElmArray= jsonObject.getJSONArray(1);
JSONArray innerArray = secondElmArray.getJSONArray(0);

JSONArray urduList= innerArray.getJSONArray(1);
String urduWord= urduList.getString(0);
