Yii フレームワークを使用して構築した Web サイトから json データを取得しようとしています。
Mozilla を開いてアクセスするhttp://localhost/restayii/index.php/employee/getemployee?id
と、従業員の json データが表示されます。
これは私の従業員のjsondataです:
{"employee":[{"id":"1","departmentId":"1","firstName":"Hendy","lastName":"Nugraha","gender":"female","birth_date":"1987-03-16","marital_status":"Single","phone":"856439112","address":"Tiban Mutiara View ","email":"hendy.nugraha87@yahoo.co.id","ext":"1","hireDate":"2012-06-30 00:00:00","leaveDate":"0000-00-00 00:00:00"},{"id":"2","departmentId":"2","firstName":"Jay","lastName":"Branham","gender":"male","birth_date":"0000-00-00","marital_status":"Single","phone":"0","address":"","email":"jaymbrnhm@labtech.org","ext":"2","hireDate":"0000-00-00 00:00:00","leaveDate":"0000-00-00 00:00:00"},{"id":"3","departmentId":"3","firstName":"Ahmad","lastName":"Fauzi","gender":"male","birth_date":"0000-00-00","marital_status":"Single","phone":"0","address":"","email":"ahmadfauzi@labtech.org","ext":"3","hireDate":"0000-00-00 00:00:00","leaveDate":"0000-00-00 00:00:00"},{"id":"4","departmentId":"1","firstName":"Henny","lastName":"Lidya Simanjuntak","gender":"female","birth_date":"1986-01-27","marital_status":"Married","phone":"2147483647","address":"Tiban Mutiara View ","email":"henokh_v@yahoo.com","ext":"1","hireDate":"0000-00-00 00:00:00","leaveDate":"0000-00-00 00:00:00"},{"id":"5","departmentId":"2","firstName":"sfg","lastName":"sfgsfg","gender":"male","birth_date":"2013-10-23","marital_status":"Single","phone":"356356","address":"sfgsfg","email":"sfgsfg","ext":"4","hireDate":"2012-05-30 00:00:00","leaveDate":"0000-00-00 00:00:00"}]}
これは Android アクティビティにあります。

問題は:
このアプリを起動して更新ボタンをクリックすると、従業員のjsonデータを含むテーブル行が表示されません。しかし、logcat にもエラーはありません。クラス Task extends AsyncTask の URL が間違っていますhttp://10.0.2.2/restayii/protected/controllers/EmployeeController.php
か??
それとも、mozilla から開いたときに同じリンクに置き換えるべきですhttp://localhost/restayii/index.php/employee/getemployee?id
か??
編集:
既に URL をhttp://localhost/restayii/index.php/employee/getemployee?id
Task Class extends AsyncTask 内に変更していますが、まだローカルホストから従業員の json データを取得できません。
お願いします、どんな助けでも大歓迎です。ありがとう
