推荐答案

您可以从请求对象生成 url:

You can generate the url from the request object:

$baseurl = $request->getScheme() . '://' . $request->getHttpHost() . $request->getBasePath();

您可以制作一个 twig 扩展程序来剪切路径的 /web 部分，并使用该请求生成基本 url.

You could make a twig extension that cuts the /web part of your path and uses the request to generate the base url.

参见 Symfony\Component\Routing\Generator\UrlGenerator::doGenerate 以获得更可靠的实现.

see Symfony\Component\Routing\Generator\UrlGenerator::doGenerate for a more solid implementation.

此外，Twig 可以访问来自 app.request 的请求.

Also, Twig has access to the request from app.request.
