Httprequest 从Symfony 4.4 HttpFoundation\Request中删除参数并重新生成URL

我需要重新生成页面的URL，删除其他参数。例如：当我收到：

https://example.com/bao1/bao2/?removeMe1=anything&keepMe1=anything&removeMe2=&keepMe2=anything

我想展示一下：

https://example.com/bao1/bao2/?keepMe1=anything&keepMe2=anything

我自动连线请求（我喜欢自动连线）：

然后我就这样玩：

public function getCleanUrl()
{
     // HttpFoundation\Request 
     $currentHttpRequest = $this->httpRequest->getCurrentRequest();

     // Trying to remove the parameters
     currentHttpRequest->query->remove("removeMe1");

     //
     return $currentHttpRequest->getUri()
}

---

query->remove（“removeMe1”）

可以工作，但是当我调用

getUri（）

时，我仍然会得到完整的输入url，就好像从来没有调用过remove（）。我想我可能没有调用某种类型的

$currentHttpRequest->regenerate（）->getUri（）

，但我找不到任何东西。

我必须让它工作，所以我设计了一个非Symfony解决方案：

$currentHttpRequest = $this->httpRequest->getCurrentRequest();

$arrParams          = $currentHttpRequest->query->all();
$arrParams          = array_intersect_key($arrParams, array_flip([
    "keepMe1", "keepMe2"
]));

$currentUrlNoQs     = strtok($currentHttpRequest->getUri(), '?');

if( empty($arrParams) ) {

    $canonical          = $currentUrlNoQs;

} else {

    $queryString        = http_build_query($arrParams);
    $canonical          = $currentUrlNoQs . '?' . $queryString;
}

return $canonical;

我不太喜欢它，但它完成了任务

$currentHttpRequest = $this->httpRequest->getCurrentRequest();

$arrParams          = $currentHttpRequest->query->all();
$arrParams          = array_intersect_key($arrParams, array_flip([
    "keepMe1", "keepMe2"
]));

$currentUrlNoQs     = strtok($currentHttpRequest->getUri(), '?');

if( empty($arrParams) ) {

    $canonical          = $currentUrlNoQs;

} else {

    $queryString        = http_build_query($arrParams);
    $canonical          = $currentUrlNoQs . '?' . $queryString;
}

return $canonical;
