將舊項目遷移到 Symfony 路由問題

[英]Migrating legacy project to Symfony routing issues

我正在嘗試開始將我的舊項目逐步遷移到 Symfony(Strangler 應用程序)。 我遵循了這個文檔,但我只能加載我的舊應用程序的 URL /我的家。 即使在我到達LegacyBridge class 之前,其他 URL 也會給我一個 404。

我想念什么?

編輯:
可能人們不明白我的問題。 我開始我的 Symfony 項目沒有問題。 我正在嘗試構建一個 Strangler 應用程序,將我的舊代碼慢慢遷移到 Symfony。 所以我的遺留代碼和 Symfony 應用程序並排運行。 但是一切都是通過 Symfony 的前端 controller 加載的。

所以我從 Symfony public/index.php

我在 Symfony 的前端 controller 中添加了 LegacyBridge class:

<?php
// public/index.php
use App\Kernel;
use App\LegacyBridge;
use Symfony\Component\Debug\Debug;
use Symfony\Component\HttpFoundation\Request;

require dirname(__DIR__).'/config/bootstrap.php';

/*
 * The kernel will always be available globally, allowing you to
 * access it from your existing application and through it the
 * service container. This allows for introducing new features in
 * the existing application.
 */
global $kernel;

if ($_SERVER['APP_DEBUG']) {
    umask(0000);

    Debug::enable();
}

if ($trustedProxies = $_SERVER['TRUSTED_PROXIES'] ?? $_ENV['TRUSTED_PROXIES'] ?? false) {
    Request::setTrustedProxies(explode(',', $trustedProxies), Request::HEADER_X_FORWARDED_ALL ^ Request::HEADER_X_FORWARDED_HOST);
}

if ($trustedHosts = $_SERVER['TRUSTED_HOSTS'] ?? $_ENV['TRUSTED_HOSTS'] ?? false) {
    Request::setTrustedHosts([$trustedHosts]);
}

$kernel = new Kernel($_SERVER['APP_ENV'], (bool) $_SERVER['APP_DEBUG']);
$request = Request::createFromGlobals();
$response = $kernel->handle($request);

/*
 * LegacyBridge will take care of figuring out whether to boot up the
 * existing application or to send the Symfony response back to the client.
 */
$scriptFile = LegacyBridge::prepareLegacyScript($request, $response, __DIR__);
if ($scriptFile !== null) {
    require $scriptFile;
} else {
    $response->send();
}
$kernel->terminate($request, $response);

我已經在$response = $kernel->handle($request);線上得到了 404 .

<?php
//src/LegacyBridge.php

namespace App;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;

class LegacyBridge
{
    public static function prepareLegacyScript(Request $request, Response $response, string $publicDirectory)
    {

        // If Symfony successfully handled the route, you do not have to do anything.
        if (false === $response->isNotFound()) {
            return;
        }

        // Figure out how to map to the needed script file
        // from the existing application and possibly (re-)set
        // some env vars.

        $dir = $request->server->get('SERVER_NAME');
        $dir = str_replace('.test', '.nl', $dir);

        $legacyScriptFilename = realpath($publicDirectory . '/../../' . $dir . '/index.php');

        return $legacyScriptFilename;
    }
}

404響應應該在您提到的行上生成(如預期的那樣),但直到下面的else塊才發送:

$scriptFile = LegacyBridge::prepareLegacyScript($request, $response, __DIR__);
if ($scriptFile !== null) {
    require $scriptFile;
} else {
    $response->send();
}

這意味着$scriptFile是 null。 因此,在您的 LegacyBridge 中添加以下內容以調試路徑:

$legacyScriptFilename = realpath($publicDirectory . '/../../' . $dir . '/index.php');

// next two lines for debug
var_dump($legacyScriptFilename);
die();

return $legacyScriptFilename;

這將轉儲$legacyScriptFilename並終止進一步的執行,因此您可以驗證路徑是否正確。

如果您遇到未捕獲的異常,請嘗試像這樣捕獲並抑制它:

try {
  $response = $kernel->handle($request);
} catch (\Exception $e) {
  $response = new Response(); 
  $response->setStatusCode(404);
}

盡管出現異常,這應該允許繼續執行。
