Android 使用http请求解析具有单个对象的url
我的url是:{aff_id} 它包含单个对象Android 使用http请求解析具有单个对象的url,android,json,parsing,android-asynctask,Android,Json,Parsing,Android Asynctask,我的url是:{aff_id} 它包含单个对象{“success”:true}。如何解析此url并将json数据存储在变量中 我的工作背景方法: protected Void doInBackground(Void... unused) { String json = ""; URL url; HttpURLConnection connection = null; try { url = new URL("http://a.nextp
{“success”:true}
。如何解析此url
并将json
数据存储在变量中
我的工作背景方法:
protected Void doInBackground(Void... unused) {
String json = "";
URL url;
HttpURLConnection connection = null;
try {
url = new URL("http://a.nextput.com/apps/init/4/a/9fe2d2cbaa8332a4633be17b79208181-2y-10-ELVM4HwkaYaCVu6203Zjfus-G/o?aff_id=");
connection = (HttpURLConnection) url.openConnection();
InputStream inputStream = connection.getInputStream();
InputStreamReader reader = new InputStreamReader(inputStream);
int data = reader.read();
while (data != -1) {
char currentChar = (char) data;
data = reader.read();
json += currentChar;
}
}catch (Exception e) {
e.printStackTrace();
} finally {
if (connection != null) {
connection.disconnect();
}
}
return json;
JSONObject jsonObject = new JSONObject(json);
boolean state = jsonObject.getBoolean("success");
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
SharedPreferences.Editor editor = prefs.edit();
editor.putBoolean("state",state);
editor.commit();
return null;
}
作为回报,json;它显示不兼容的类型,在JSONObject中显示未处理的异常:org.json.JSONException。如何解决此问题?以下是此问题的解决方案-
// Making HTTP request
InputStream is = null;
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);//YOUR URL
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 {
JSONObject jObj = new JSONObject(json);
boolean isSuccess = jObj.getBoolean("success");
System.out.println("success : " + isSuccess);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
有很多json解析的例子……请先尝试一下。@RavindraKushwaha的可能重复项与您提出的问题不同。我尝试过json解析。但这里只有一个对象,那就是响应。我不知道如何在此url中执行解析。请帮忙。你试过什么@himanshutiwari。。。??它使用起来很简单,比如JsonObject JsonObject=newjsonobject(“这是您的响应”);而不是字符串suces=jsonobject.getBoolean(“成功”)@RavindraKushwaha我编辑了这个问题并展示了我的尝试。这给了我们一些错误。我在上一篇文章中也提到了他们。请帮助我解决它们。在您的代码中,它显示无法解决符号“is”InputStream is=null;
