Answer 1

1、普通的get和pst请求$request = Yii::$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']) ? $_GET['id'] : 1;//添加了默认值$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']) ? $_POST['name'] : '';//添加了默认值2、判断请求属性$request = Yii::$app->request;if ($request->isAjax) { // 判断是否为AJAX 请求 }if ($request->isGet) { // 判断是否为GET 请求 }if ($request->isPost) { // 判断是否为POST 请求}if ($request->isPut) { // 判断是否为PUT 请求 }3、获取请求头信息// $headers is an object of yii\web\HeaderCollection$headers = Yii::$app->request->headers;// 返回header头部所有信息$accept = $headers->get('Accept');if ($headers->has('User-Agent')) { // 获取User-Agent }4、获取用户客户端信息$userHost = Yii::$app->request->userHost;$userIP = Yii::$app->request->userIP;
