Android通过php插入查询SQL数据库

PHP代码

<?php

header("Content-type: text/html; charset=gb2312");
$serverName = "localhost"; //数据库服务器地址
$uid = "Mssqla"; //数据库用户名
$pwd = "123456"; //数据库密码
$connectionInfo = array("UID"=>$uid, "PWD"=>$pwd, "Database"=>"mysql");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if($conn == false){
    echo "连接数据库失败";
}else{
    echo "连接数据库成功";
}
$name = $_POST['name'];
$pass = $_POST['pass'];
$security = $_POST['security'];
print($name);

sqlsrv_query($conn, "insert into android (name,pass,security) values('$name','$pass','$security')");

//定义好一个数组。PHP中array相当于一个数据字典
$data =array();
//定义一个类,用到存放从数据库中取出的数据.
class User{
   public $name;
   public $pass;
}

$query = sqlsrv_query($conn, "select * from myuser");
while($row = sqlsrv_fetch_array($query)){
   $user = new User();
   $user->name = $row['name'];
   $user->pass = $row['pass'];
   $data[] = $user;
}
$json = json_encode($data); //把数据转换为JSON数据
print("{".'"user"'.":".$json."}");

sqlsrv_close($conn);

Android代码

public static final int ISLOGIN =1;

            private void sendRequestWithHttpClient(){
               new Thread(new Runnable() {
                   @Override
                   public void run() {
                       //创建键/值组列表
                       List<NameValuePair> pairs = new ArrayList<NameValuePair>();
                       pairs.add(new BasicNameValuePair("name", qq_name.getText().toString()));
                       pairs.add(new BasicNameValuePair("pass", qq_pass.getText().toString()));
                       pairs.add(new BasicNameValuePair("security", security.getText().toString()));
                       try{
                           HttpClient httpClient = new DefaultHttpClient();   //定义HttpClient
                           HttpPost httpPost = new HttpPost("http://.........../android/registered.php"); //实例化HTTP方法
                           UrlEncodedFormEntity entity = new UrlEncodedFormEntity(pairs,"gb2312");
                           httpPost.setEntity(entity);
                           HttpResponse httpResponse = httpClient.execute(httpPost);     //执行请求
                           //处理返回数据
                           HttpEntity httpentity =httpResponse.getEntity();
                           InputStream is =httpentity.getContent();
                           BufferedReader reader = new BufferedReader(
                                   new InputStreamReader(is,"gb2312"));
                           StringBuilder sb =new StringBuilder();
                           sb.append(reader.readLine() +" ");
                           String line ="0";
                           while((line =reader.readLine())!=null){
                               sb.append(line +" ");
                           }
                           is.close();
                           result = sb.toString();

                           Message message = new Message();
                           message.what = ISLOGIN;
                           handler.sendMessage(message); // 将Message对象发送出去,采用异步处理机制

                           if(httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK){
                           //   String result = EntityUtils.toString(httpResponse.getEntity());
                           }else{
                           }
                       }catch(UnsupportedEncodingException e){
                           e.printStackTrace();
                       }catch(ClientProtocolException e){
                           e.printStackTrace();
                       }catch (IOException e) {
                           e.printStackTrace();
                       }
                   }
               }).start();
           }

//异步处理的代码

   @SuppressLint("HandlerLeak")
   private Handler handler = new Handler() {
       public void handleMessage(Message msge) {
           switch (msge.what) {
           case ISLOGIN:

// 在这里可以进行UI操作

                Toast.makeText(LoginActivity.this, "account or password   is invalid",
               Toast.LENGTH_SHORT).show();
               break;
           default:
               break;
           }
       }
   };

注意：重新开启一个线程处理HttpClient请求，不要在UI线程处理，注意编码方式，如果出现乱码，数据库插入操作失败，将返回null值。
