Question

我在这里遇到的问题是从服务器：http://XXX.XXX.XXX.XXX:9090/appsapi/rest/services/getStudentPersonalDetails/123789读取一个json数组，这个json数组中没有json对象。它就像下面一样。：

{"password":"raj","address":"dfsaf","state":"tamilnadu","image":"Bindu Appalam.jpg",
 "dept":"BE(Mech)","fname":"fasdf","mname":"saffd","dob":"14/12/1951","sex":"Male",
 "email":"fdasd@gmail.com","contact":"212121212545855555545","city":"dsfadf",
 "pin":"600106","sname":"fdjsf","studid":"123789"}

我想解析它..

我试图从httpclient请求中获取如下所示的json数组：

try {

            System.out.println("url tt : "+url);
            // http client
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpEntity httpEntity = null;
            HttpResponse httpResponse = null;

            System.out.println(" Urls Input to "+url);

            // Checking http request method type
            if (method == POST) {
                HttpPost httpPost = new HttpPost(url);
                // adding post params
                if (params != null) {
                    httpPost.setEntity(new UrlEncodedFormEntity(params));
                }

                httpResponse = httpClient.execute(httpPost);

            } else if (method == GET) {
                // appending params to url
                System.out.println(" Params Valyes "+params);

                if (params != null) {
                    String paramString = URLEncodedUtils.format(params, "utf-8");
                    url += "?" + paramString;
                    System.out.println(" Params String "+paramString);
                }
                HttpGet httpGet = new HttpGet(url);
                httpResponse = httpClient.execute(httpGet);
            }

            httpEntity = httpResponse.getEntity();
            response = EntityUtils.toString(httpEntity);

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

但在回复时得到以下错误：

任何身体，请帮助......

Answer 1

在你的代码中，没有json数组，它是带有名称值对数据的json对象。因此，您必须解析JSONObject而不是JSONArray。

喜欢：

JSONObject json = new JSONObject(jsonString);

String password = json.getString("password");

同样，您可以获取对象的所有值。

Answer 2

JSON对象以{开头，以{结尾}，而JSON数组以[以＃结尾]开头。

在您的情况下，请更改代码以改为使用JSONObject。

JSONObject json = new JSONObject(jsonString);
JSONArray jArray = json.getJSONArray("list");

System.out.println("*****JARRAY*****"+jArray.length());
for(int i=0;i<jArray.length();i++){


 JSONObject json_data = jArray.getJSONObject(i);
 Log.i("log_tag","_id"+json_data.getInt("account")+
  ", mall_name"+json_data.getString("name")+
  ", location"+json_data.getString("number")+
  ", telephone"+json_data.getString("url")+
  ",----"+json_data.getString("balance")+
  ",----"+json_data.getString("credit")+
  ",----"+json_data.getString("displayName")
 );

}
