类型 org.json.JSONArray 的值无法转换为 JSONObject
卡在此错误:
3169-3190/com.meisolsson.app E/JSON Parser: Error parsing data org.json.JSONException: Value [{“type”:0,“can_see_custom_stories”:true,“display”:“”,“name”:“jenniaim”},{“type”:0,“can_see_custom_stories”:true,“display”:“”,“name”:“lucasgardebrand”},{“type”:0,“can_see_custom_stories”:true,“display”:“”,“name”:“herr_anderzzon”},{“type”:0,“can_see_custom_stories”:true,“display”:“”,“name”:“chrillebile”},{“type”:0,“can_see_custom_stories”:true,“display”:“”,“name”:“meisolsson”},{“type”:0,“can_see_custom_stories”:true,“display”:“”,“name”:“sakanapanda”},{“type”:0,“can_see_custom_stories”:true,“display”:“Team Snapchat”,“name”:“teamsnapchat”},{“type”:0,“can_see_custom_stories”:true,“display”:“”,“name”:“fabianlindfors”},{“type”:0,“can_see_custom_stories”:true,“display”:“Katja”,“name”:“katjaawesome”},{“type”:0,“can_see_custom_stories”:true,“display”:“”,“name”:“swimkey”},{“type”:1,“can_see_custom_stories”:true,“display”:“”,“name”:“agnesholmberg”}] 的 org.json.JSONArray 类型无法转换为 JSONObject
所以这是代码:
public class JSONParser extends AsyncTask<Void, Void, Boolean> {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {
}
public JSONObject getJSONFromUrl(String url) {
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("username", LoginActivity.Suser));
nameValuePairs.add(new BasicNameValuePair("password", LoginActivity.Spass));
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
@Override
protected Boolean doInBackground(Void... params) {
getJSONFromUrl("http://flapplabs.se/development/snapchat/friends.php");
return null;
}
}
