我怎么能检测到哪个请求类型被使用(GET, POST, PUT或删除)在PHP?


当前回答

在core php中,你可以这样做:

<?php

$method = $_SERVER['REQUEST_METHOD'];

switch ($method) {
  case 'GET':
    //Here Handle GET Request
    echo 'You are using '.$method.' Method';
    break;
  case 'POST':
    //Here Handle POST Request
    echo 'You are using '.$method.' Method';
    break;
  case 'PUT':
    //Here Handle PUT Request
    echo 'You are using '.$method.' Method';
    break;
  case 'PATCH':
    //Here Handle PATCH Request
    echo 'You are using '.$method.' Method';
    break;
  case 'DELETE':
    //Here Handle DELETE Request
    echo 'You are using '.$method.' Method';
    break;
  case 'COPY':
      //Here Handle COPY Request
      echo 'You are using '.$method.' Method';
      break;

  case 'OPTIONS':
      //Here Handle OPTIONS Request
      echo 'You are using '.$method.' Method';
      break;
  case 'LINK':
      //Here Handle LINK Request
      echo 'You are using '.$method.' Method';
      break;
  case 'UNLINK':
      //Here Handle UNLINK Request
      echo 'You are using '.$method.' Method';
      break;
  case 'PURGE':
      //Here Handle PURGE Request
      echo 'You are using '.$method.' Method';
      break;
  case 'LOCK':
      //Here Handle LOCK Request
      echo 'You are using '.$method.' Method';
      break;
  case 'UNLOCK':
      //Here Handle UNLOCK Request
      echo 'You are using '.$method.' Method';
      break;
  case 'PROPFIND':
      //Here Handle PROPFIND Request
      echo 'You are using '.$method.' Method';
      break;
  case 'VIEW':
      //Here Handle VIEW Request
      echo 'You are using '.$method.' Method';
      break;
  Default:
    echo 'You are using '.$method.' Method';
  break;
}

其他回答

通过使用

$_SERVER['REQUEST_METHOD']

例子

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
     // The request is using the POST method
}

要了解更多细节,请参阅$_SERVER变量的文档。

因为这是关于REST的,所以仅仅从服务器获取请求方法是不够的。您还需要接收RESTful路由参数。分离RESTful参数和GET/POST/PUT参数的原因是资源需要有自己的唯一URL用于标识。

下面是使用Slim在PHP中实现RESTful路由的一种方法:

https://github.com/codeguy/Slim

$app = new \Slim\Slim();
$app->get('/hello/:name', function ($name) {
  echo "Hello, $name";
});
$app->run();

并相应地配置服务器。

下面是另一个使用AltoRouter的例子:

https://github.com/dannyvankooten/AltoRouter

$router = new AltoRouter();
$router->setBasePath('/AltoRouter'); // (optional) the subdir AltoRouter lives in

// mapping routes
$router->map('GET|POST','/', 'home#index', 'home');
$router->map('GET','/users', array('c' => 'UserController', 'a' => 'ListAction'));
$router->map('GET','/users/[i:id]', 'users#show', 'users_show');
$router->map('POST','/users/[i:id]/[delete|update:action]', 'usersController#doAction', 'users_do');

在core php中,你可以这样做:

<?php

$method = $_SERVER['REQUEST_METHOD'];

switch ($method) {
  case 'GET':
    //Here Handle GET Request
    echo 'You are using '.$method.' Method';
    break;
  case 'POST':
    //Here Handle POST Request
    echo 'You are using '.$method.' Method';
    break;
  case 'PUT':
    //Here Handle PUT Request
    echo 'You are using '.$method.' Method';
    break;
  case 'PATCH':
    //Here Handle PATCH Request
    echo 'You are using '.$method.' Method';
    break;
  case 'DELETE':
    //Here Handle DELETE Request
    echo 'You are using '.$method.' Method';
    break;
  case 'COPY':
      //Here Handle COPY Request
      echo 'You are using '.$method.' Method';
      break;

  case 'OPTIONS':
      //Here Handle OPTIONS Request
      echo 'You are using '.$method.' Method';
      break;
  case 'LINK':
      //Here Handle LINK Request
      echo 'You are using '.$method.' Method';
      break;
  case 'UNLINK':
      //Here Handle UNLINK Request
      echo 'You are using '.$method.' Method';
      break;
  case 'PURGE':
      //Here Handle PURGE Request
      echo 'You are using '.$method.' Method';
      break;
  case 'LOCK':
      //Here Handle LOCK Request
      echo 'You are using '.$method.' Method';
      break;
  case 'UNLOCK':
      //Here Handle UNLOCK Request
      echo 'You are using '.$method.' Method';
      break;
  case 'PROPFIND':
      //Here Handle PROPFIND Request
      echo 'You are using '.$method.' Method';
      break;
  case 'VIEW':
      //Here Handle VIEW Request
      echo 'You are using '.$method.' Method';
      break;
  Default:
    echo 'You are using '.$method.' Method';
  break;
}

值得注意的是,即使您发送了其他类型的请求,PHP也会填充所有的$_GET参数。

上述回复中的方法是完全正确的,但是如果你想在处理POST, DELETE, PUT等请求时额外检查GET参数,你需要检查$_GET数组的大小。

这是非常简单的使用$_SERVER['REQUEST_METHOD'];

例子:

<?php
$method = $_SERVER['REQUEST_METHOD'];
switch ($method) {
  case 'GET':
    //Here Handle GET Request 
    break;
  case 'POST':
    //Here Handle POST Request 
    break;
  case 'DELETE':
    //Here Handle DELETE Request 
    break;
  case 'PUT':
    //Here Handle PUT Request 
    break;
}
