Android(安卓)HTTP GET/POST

android程序HTTP通信的简单示例。纯粹是为了学习+测试，所以存在代码冗余的现象。从一个最简单的登录验证开始，数据的提交方式分别使用GET和POST，利用Toast来提示登录结果。

android http get and post

android.php源码：

<?php    $REQUEST_METHOD = $_SERVER['REQUEST_METHOD'];    echo $REQUEST_METHOD;    if($REQUEST_METHOD == 'GET'){        $name = $_GET['name'];        $pwd = $_GET['pwd'];                if($name == 'Neeke' && $pwd == 'Neeke'){            echo '你好：'.$name;        }else{            echo '登录失败！';        }    }else if($REQUEST_METHOD == 'POST'){        $name = $_POST['name'];        $pwd = $_POST['pwd'];                if($name == 'Neeke' && $pwd == 'Neeke'){            echo '你好：'.$name;        }else{            echo '登录失败！';        }    }?>

android主程序源码：

public class Main extends Activity {private Button btnGet;private Button btnPost;private EditText etName;private EditText etPwd;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        btnGet = (Button) findViewById(R.id.btnGet);        btnPost = (Button) findViewById(R.id.btnPost);        etName = (EditText) findViewById(R.id.etName);        etPwd = (EditText) findViewById(R.id.etPassword);                btnGet.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {HttpGet request = new HttpGet("http://www.ineeke.com/android/android.php?name="+etName.getText().toString()+"&pwd="+etPwd.getText().toString());try {HttpResponse response = new DefaultHttpClient().execute(request);if(response.getStatusLine().getStatusCode() == 200){String result = EntityUtils.toString(response.getEntity());Toast.makeText(Main.this, result, Toast.LENGTH_LONG).show();}} catch (Exception e) {Toast.makeText(Main.this, e.getMessage().toString(), Toast.LENGTH_LONG).show();e.printStackTrace();}}});                btnPost.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {HttpPost request = new HttpPost("http://www.ineeke.com/android/android.php");List<NameValuePair> params = new ArrayList<NameValuePair>();params.add(new BasicNameValuePair("name", etName.getText().toString()));params.add(new BasicNameValuePair("pwd", etPwd.getText().toString()));try {request.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));HttpResponse response = new DefaultHttpClient().execute(request);if(response.getStatusLine().getStatusCode() == 200){String result = EntityUtils.toString(response.getEntity());Toast.makeText(Main.this, result, Toast.LENGTH_LONG).show();}} catch (Exception e) {Toast.makeText(Main.this, e.getMessage().toString(), Toast.LENGTH_LONG).show();e.printStackTrace();}}});    }}

最后，千万千万不要忘记要赋予程序访问网络的权限！因为我就经常忘记权限的问题，导致出了问题郁闷老半天。
在AndroidManifest.xml加入：

<uses-permission android:name="android.permission.INTERNET" />
