nikic/FastRoute请求后参数访问

Question

我正在尝试使用FastRoute实现简单的POST请求。通过下面的例子，我成功地实现了GET类型请求。在实现POST请求时，我无法访问随请求发送的参数。

$dispatcher = FastRoutesimpleDispatcher(function(FastRouteRouteCollector $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 FastRouteDispatcher::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";
}
}

我尝试检查$_POST，但是，它是空的。

在搜索了大量关于nikic/FastRoute帖子请求的信息后，偶然发现了这篇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 = FastRoutesimpleDispatcher(function(FastRouteRouteCollector $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 FastRouteDispatcher::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";
}
}
