一 android獲取php數據
步驟：
1 加入權限：
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
2啟動一個新線程
android4.0開始不允許直接在ui線程直接操作httpClient
3 註意url:https://10.0.2.2/testAndroid.php
(不要填寫:127.0.0.1 這個是本機電腦的,模擬器有自己的默認ip)
4通過handler將數據從新線程中傳送出來
MainActivity.java======================
public class MainActivity extends Activity {
public final static String EXTRA_MESSAGE = "com.example.myapp.MESSAGE";
HttpClient client;
public String res;
public Handler myHandler;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myHandler = new Handler(){
public void handleMessage(Message msg){
if(msg.what == 0x123){
Toast toast = Toast.makeText(MainActivity.this,msg.obj.toString(),Toast.LENGTH_SHORT);
toast.show();
}
}
};
}
public void sendMessage(View view) {
startUrlCheck();
}
private void startUrlCheck()
{
new Thread(){
public void run(){
client = new DefaultHttpClient();
StringBuilder builder = new StringBuilder();
HttpGet myget = new HttpGet("https://10.0.2.2/testAndroid.php");
//HttpGet myget = new HttpGet("https://www.crazyit.org");
try {
HttpResponse response = client.execute(myget);
HttpEntity entity = response.getEntity();
BufferedReader reader = new BufferedReader(new InputStreamReader(entity.getContent()));
for (String s = reader.readLine(); s != null; s = reader.readLine()) {
builder.append(s);
}
JSONObject jsonObject = new JSONObject(builder.toString());
String re_password = jsonObject.getString("password");
res = re_password;
Message msg = new Message();
msg.what = 0x123;
msg.obj = res;
myHandler.sendMessage(msg);
} catch (Exception e) {
e.printStackTrace();
}
}
}.start();
}
}
testAndroid.php===================================
<?php
$array = array(
'username'=>'楊鑄',
'password'=>'123456',
'user_id'=>1
);
echo json_encode($array);
?>
