Php Guzzle 5中的Setter不允许在Guzzle 6中使用

我正在使用Guzzle对我在Symfony2中开发的API进行测试

我一直在看knpUniversity的Rest系列，我在更新应该能够使用app_test.php而不是app.php的部分时遇到了问题。 在该系列中，他们使用Guzzle v5，但在v6中有一些重大变化

在本教程中，要允许使用以app.php以外的其他uri，请执行以下操作：

但是对于Guzzle6，没有用于请求的setter：

use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;
use GuzzleHttp\Middleware;
use Psr\Http\Message\RequestInterface;
use Psr\Http\Message\ResponseInterface;
use Symfony\Bundle\FrameworkBundle\Test\KernelTestCase;


class ApiTestCase extends KernelTestCase
{
    private static $staticClient;

    protected $client;

    public static function setUpBeforeClass()
    {
        //defined in phpunit.xml
        $baseUri = getenv('TEST_BASE_URI');

        //Create a handler stack that has all of the default middlewares attached
        $handler = HandlerStack::create();

        // guaranteeing that /app_test.php is prefixed to all URLs
        $handler->push(Middleware::mapRequest(function (RequestInterface $request) {
            $path = $request->getUri()->getPath();
            if (strpos($path, '/api') === 0) {
                $request->getUri()->setPath('/app_test.php'.$path);  // <-- this is not allowed
            }
            // Notice that we have to return a request object
            return $request->withHeader('X-Foo', 'Bar');
        }));

        // Inject the handler into the client
        self::$staticClient = new Client([
            'base_uri' => $baseUri.'/app_test.php',
            'handler' => $handler,
            'defaults' => [
                'http_errors' => false
            ]
        ]);

        //Allows to use service container
        self::bootKernel();
    }

谢谢@Cerad

我想像$request=$request->getUri（）->withPath（）这样的东西会有用。可能需要获取uri对象，然后使用$request->withUri（）。`$handler->push（中间件：：mapRequest（函数（RequestInterface$request）{$path=$request->getUri（）->getPath（）；if（strpos（$path，'/api/v1'）==0）{$uri=$request->getUri（）->withPath（'/app_test.php.$path）；$request->withUri（$uri）；}var_dump（$request->getUri（）->getPath（））；return$request->withHeader（'X-Foo'，'Bar'）；}）；`仍然显示没有前缀的uri。我认为像$request=$request->getUri（）->withPath（）这样的东西可以工作。可能需要获取uri对象，然后使用$request->withUri（）。`$handler->push（中间件：：mapRequest（函数（RequestInterface$request）{$path=$request->getUri（）->getPath（）；if（strpos（$path，'/api/v1'）==0）{$uri=$request->getUri（）->withPath（'/app_test.php.$path）；$request->withUri（$uri）；}var_dump（$request->getUri（）->getPath（））；return$request->withHeader（'X-Foo'，'Bar'）；}）；`仍然显示不带前缀的uri。
