Question

Zend PSR7似乎不适用于Lumen：

use Psr\Http\Message\ServerRequestInterface;
use Zend\Diactoros\Response;

// PSR 7
$app->bind('Psr\Http\Message\ServerRequestInterface', function ($app) {
    return (new Symfony\Bridge\PsrHttpMessage\Factory\DiactorosFactory)->createRequest($app->make('request'));
});

// PSR 7.
$app->get('hello/{name}', function (ServerRequestInterface $request) {

    // Interact with the PSR-7 request
    $name = $request->getAttribute('name');

    // var_dump($request->getHeaders());
    var_dump($name); // get NULL instead of 'world'

    // Interact with the PSR-7 response
    $response = new Response();
    $response->getBody()->write('Hello, ' . $name);

    return $response->withHeader('Content-type', 'application/json');
});

第一个'错误'：

var_dump($name); // get NULL instead of 'world'

第二个错误：

UnexpectedValueException in Response.php line 395:
The Response content must be a string or object implementing __toString(), "object" given.

任何想法为什么？

Slim3似乎更容易，更直接！

Answer 1

您可以尝试my PSR HTTP library：

$response = new \Shieldon\Psr7\Response();

Zend PSR7对Lumen不起作用？
