我寫了一個簡單的PHP腳本,打印一個jsonencode($ output)。它輸出帶有前導和結尾[]的JSON。當我通過emulaotor運行Android程序時,它指出:JSONObject文本必須以[{'字符1開頭,然後列出我的JSON,因此我知道它獲取數據,解碼過程中不去除那些方括號。下面是引發錯誤的日誌功能:通過PHP連接MySQL,JSON錯誤
public class JSONfunctions {
public static JSONObject getJSONfromURL(String url){
InputStream is = null;
String result = "";
JSONObject jArray = null;
//http post
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
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());
}
try{
jArray = new JSONObject(result);
}catch(JSONException e){
Log.e("log_tag", "Error parsing data "+e.toString());
}
return jArray;
}
}
但默認打印(jsonencode($輸出));來自PHP的格式不帶標題和方括號。沒辦法改變這一點。 – savagenoob
