1、普通的get和post請(qǐng)求
$request= Yii::$app->request;
$get=$request->get();
// equivalent to: $get = $_GET;
$id=$request->get('id');
// equivalent to: $id = isset($_GET['id']) ? $_GET['id'] : null;
$id=$request->get('id', 1);
// equivalent to: $id = isset($_GET['id']) ? $_GET['id'] : 1;
//添加了默認(rèn)值
$post=$request->post();
// equivalent to: $post = $_POST;
$name=$request->post('name');
// equivalent to: $name = isset($_POST['name']) ? $_POST['name'] : null;
$name=$request->post('name','');
// equivalent to: $name = isset($_POST['name']) ? $_POST['name'] : '';
//添加了默認(rèn)值
2、判斷請(qǐng)求屬性
$request = Yii::$app->request;
if ($request->isAjax) { // 判斷是否為AJAX 請(qǐng)求 }
if ($request->isGet) { // 判斷是否為GET 請(qǐng)求 }
if ($request->isPost) { // 判斷是否為POST 請(qǐng)求}
if ($request->isPut) { // 判斷是否為PUT 請(qǐng)求 }
3、獲取請(qǐng)求頭信息
// $headers is an object of yii\web\HeaderCollection
$headers = Yii::$app->request->headers;
// 返回header頭部所有信息
$accept = $headers->get('Accept');
if ($headers->has('User-Agent')) { // 獲取User-Agent }
4、獲取用戶客戶端信息
$userHost = Yii::$app->request->userHost;
$userIP = Yii::$app->request->userIP;
