更改 Slim 请求属性

Question

如何更改 Slim 请求的 URI 路径？我尝试了以下方法，但是，withPath() 克隆了 uri，因此请求对象没有改变。如果不可能，是否有一个简单的过程可以根据原始请求但新的 URI 路径创建新的 Slim 请求？

关于我为什么要这样做的背景。我有一个方法可以接受 Slim 请求，使用 Guzzle 向另一台服务器执行 cURL 请求，写入 Slim 响应，然后 returns Slim 响应。 API Guzzle 查询几乎相同的路径但带有版本号。

$app->get('/{basetype:guids|tester}/{guid}/logs/{id:[0-9]+}', function (Request $request, Response $response, $args) {
    switch($request->getQueryParam('ContentType')) {
        case 'text':
            //
            return $this->view->render($response, 'log.html', $rs);
        case 'file':
            $uri=$request->getUri();
            $path=$uri->getPath();
            $uri->withPath(_VER_.$path);
            return $this->serverBridge->proxy($request, $response, 'application/octet-stream');
    }
});

class ServerBridge
{
    protected $httpClient;

    public function __construct(\GuzzleHttp\Client $httpClient)
    {
        $this->httpClient=$httpClient;
    }

    public function proxy(\Slim\Http\Request $slimRequest, \Slim\Http\Response $slimResponse):\Slim\Http\Response {
        //$slimRequest is used to obtain data to send to Guzzle 
        $curlResponse = $this->httpClient->request($method, $path, $options);
        //use $curlResponse to get data and write to $slimResponse
        return $slimResponse;
    }
}

如果更改 Uri 路径，则也必须更改请求。这是设计使然。别担心，克隆在 PHP.

很便宜

<?php

$request = $request->withUri($request->getUri()->withPath('your/changed/path'));

Note: Be careful to use that new $request in some other calls in the middleware stack. They were made immutable for a reason. Changing the uri of a request early in the execution can have undesirable side effects.
