您好,我試圖從json中的PHP腳本獲取數據。我得到幾個錯誤:第一個變量沒有解決。如果我嘗試添加像下面這樣的新變量,那麼在運行應用程序之後,我會收到一個錯誤,指出轉換錯誤。它主要是一個教程代碼,但正如我之前所說的那樣是一個IS變量的問題。你可以幫我嗎?連接到mysql的問題
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("year","1980"));
InputSteam is = null;
//http post
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://ik.su.lt/~jbarzelis/bandymas/getAllPeopleBornAfter.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
InputStream is = entity.getContent();
}catch(Exception e){
Log.e("log_tag", "Error in http connection "+e.toString());
}
//convert response to string
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();
result=sb.toString();
}catch(Exception e){
Log.e("log_tag", "Error converting result "+e.toString());
}
//parse json data
try{
JSONArray jArray = new JSONArray(result);
for(int i=0;i<jArray.length();i++){
JSONObject json_data = jArray.getJSONObject(i);
Log.i("log_tag","id: "+json_data.getInt("id")+
", name: "+json_data.getString("name")+
", sex: "+json_data.getInt("sex")+
", birthyear: "+json_data.getInt("birthyear")
);
}
}
catch(JSONException e){
Log.e("log_tag", "Error parsing data "+e.toString());
}
}
首先你要問一個問題。 – ahanin 2012-04-07 14:53:26
問題將是如何解決它或我缺少的。但我認爲這已經可以理解了。 – LTnewbie 2012-04-07 14:55:00
請發佈實際的錯誤消息,或花更多的時間來解釋您的實際問題。 – Mat 2012-04-07 14:58:49
