php - nikic/FastRoute post请求参数访问

Question

我正在尝试使用 FastRoute 实现简单的 POST 请求。我按照给定的示例成功实现了 GET 类型的请求。在实现 POST 请求时，我无法访问随请求发送的参数。

$dispatcher = FastRoute\simpleDispatcher(function(FastRoute\RouteCollector $r) {
  $r->addRoute('POST', '/login', 'Test/put');
  $r->addRoute('GET', '/users/{id:\d+}', 'Test/put');
});

$httpMethod = $_SERVER['REQUEST_METHOD'];
$uri = $_SERVER['REQUEST_URI'];

if (false !== $pos = strpos($uri, '?')) {
 $uri = substr($uri, 0, $pos);
}

$uri = rawurldecode($uri);

$routeInfo = $dispatcher->dispatch($httpMethod, $uri);
switch ($routeInfo[0]) {
 case FastRoute\Dispatcher::FOUND:
  $handler = $routeInfo[1];
  $vars = $routeInfo[2];
  list($class, $method) = explode("/", $handler, 2);
  call_user_func_array(array(new $class, $method), $vars);
  break;
}

class Test {
 public function put() {
  return "Check";
 }
}

我试图检查$_POST，但是，那是空的。

在搜索了有关 nikic/FastRoute 发布请求的大量信息后，偶然发现了这个stackoverflow 帖子。之后对代码进行了以下更改。

$_POST = json_decode(file_get_contents('php://input' ),true);

$dispatcher = FastRoute\simpleDispatcher(function(FastRoute\RouteCollector $r) {
  $r->addRoute('POST', '/login', 'Test/put');
  $r->addRoute('GET', '/users/{id:\d+}', 'Test/put');
});

$httpMethod = $_SERVER['REQUEST_METHOD'];
$uri = $_SERVER['REQUEST_URI'];

if (false !== $pos = strpos($uri, '?')) {
 $uri = substr($uri, 0, $pos);
}

$uri = rawurldecode($uri);
$httpMethod = $_SERVER['REQUEST_METHOD'];
$routeInfo = $dispatcher->dispatch($httpMethod, $uri);
switch ($routeInfo[0]) {
 case FastRoute\Dispatcher::FOUND:
   $handler = $routeInfo[1];
   $vars = ($httpMethod == 'POST')? $_POST : $routeInfo[2];;
   list($class, $method) = explode("/", $handler, 2);
   call_user_func_array(array(new $class, $method), $vars);
   break;
}

class Test {
  public function put() {
    return "Check";
  }
}
