我在读取从服务器获取的 json 数组时遇到问题:http://XXX.XXX.XXX.XXX:9090/appsapi/rest/services/getStudentPersonalDetails/123789 ,这个 json 数组里面没有 json 对象。如下图:
{"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..
我尝试从 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();
}
但在响应中出现以下错误:

任何人,请在这里帮忙...
最佳答案
JSON 对象以 { 开头并以 } 结尾,而 JSON 数组以 [ 开头并以 . 结尾。
在您的情况下,更改您的代码以使用 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")
);
}
