在PHP中检测请求类型(GET,POST,PUT或DELETE)

Question

如何在PHP中检测使用了哪种请求类型(GET,POST,PUT或DELETE)？

Answer 1

通过使用

$_SERVER['REQUEST_METHOD']

例

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

有关更多详细信息,请参阅$ _SERVER变量的文档.

Answer 2

PHP中的REST可以非常简单地完成.创建http://example.com/test.php(概述如下).用于REST调用,例如http://example.com/test.php/testing/123/hello.这适用于Apache和Lighttpd开箱即用,不需要重写规则.

<?php
$method = $_SERVER['REQUEST_METHOD'];
$request = explode("/", substr(@$_SERVER['PATH_INFO'], 1));

switch ($method) {
  case 'PUT':
    do_something_with_put($request);  
    break;
  case 'POST':
    do_something_with_post($request);  
    break;
  case 'GET':
    do_something_with_get($request);  
    break;
  default:
    handle_error($request);  
    break;
}

Answer 3

REQUEST METHOD可以使用以下代码片段来检测所谓的HTTP方法.

$method = $_SERVER['REQUEST_METHOD']
if ($method == 'POST') {
    // Method is POST
} elseif ($method == 'GET') {
    // Method is GET
} elseif ($method == 'PUT') {
    // Method is PUT
} elseif ($method == 'DELETE') {
    // Method is DELETE
} else {
    // Method unknown
}

switch如果你喜欢这个,你也可以使用a if-else.

如果html表单中的方法不是GET或POST需要,则通常使用表单中的隐藏字段来解决.

<!-- DELETE method -->
<form action='' method='POST'>
    <input type="hidden" name'_METHOD' value="DELETE">
</form>

<!-- PUT method -->
<form action='' method='POST'>
    <input type="hidden" name'_METHOD' value="PUT">
</form>

由于这是关于REST,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唯一的URL用于标识.

这是使用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.

这是使用AltoRouter的另一个例子:

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');

Answer 5

我们还可以使用input_filter来检测请求方法,同时还通过输入卫生提供安全性.

$request = filter_input(INPUT_SERVER, 'REQUEST_METHOD', FILTER_SANITIZE_ENCODED);

Answer 6

您可以使用getenv函数,而不必使用$_SERVER变量:

getenv('REQUEST_METHOD');

Answer 7

在核心 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;
}


?>

Answer 8

长话短说

“true 的本机来源”是$_SERVER全局变量。请求方法保存在“REQUEST_METHOD”键下。

检查 $_SERVER 数组

$_SERVER['REQUEST_METHOD']

PHP 方法

但是您可以使用很多变通方法来获取该方法。像filter_input一样： filter_input(INPUT_SERVER, 'REQUEST_METHOD', FILTER_SANITIZE_ENCODED);

库 或者您使用外部库，例如：

• Symfony\Component\HttpFoundation\Request
• \Zend\Http\PhpEnvironment\Request

结论

但最简单的方法是使用：$_SERVER['REQUEST_METHOD']。

Answer 9

非常简单只需使用$ _SERVER ['REQUEST_METHOD'];

例:

<?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;
}
?>

Answer 10

$request = new \Zend\Http\PhpEnvironment\Request();
$httpMethod = $request->getMethod();

通过这种方式,您还可以在zend框架2中实现.谢谢.
