yii2 的request get pos请求 基本用法示例

yii2好久没用了， 基本的都快忘了，赶紧记录一下。

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

$headers = Yii::$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;
