迁移到 Laravel 5，route:cache 抛出异常

Question

从 Laravel 4.2 升级到 5.0

我们的 API 中有大约 200 条路线，其中大部分是闭包。所以我花了最近几天的大部分时间将它们全部转换为控制器路由。一切都恢复稳定，但是当我尝试运行 php artisan route:cache 它抛出异常

[Exception]
Serialization of 'Closure' is not allowed

我为 function 按了 ctrl+f，路由文件中只剩下两个 Route::group 条目（是的，它们是闭包...但肯定只有路由数...)。

有什么指导吗？折腾了这两天，这个错误……不是我想看到的

编辑：完整堆栈跟踪

路由缓存已清除！

编辑 2：删除了要测试的路由组，仍然抛出异常

Answer 1

根据您的堆栈跟踪，

vendor\laravel\framework\src\Illuminate\Foundation\Console\RouteCacheCommand.php:95
serialize() at vendor\laravel\framework\src\Illuminate\Foundation\Console\RouteCacheCommand.php:95

Laravel 正在尝试序列化路由集合 on line 95 of RouteCacheCommand.php。

您遇到的错误

Serialization of 'Closure' is not allowed

看起来像其 PHP 的标准 "someone tried to serialize an anonymous function" 异常消息（相对于它可能是自定义 Laravel 异常）。

这意味着某事正在向您的路由集合添加匿名函数（即 "closure"）。如果您 100% 确定已将它们全部从 routes.php 中删除，我猜该路由在某处的第三方代码中。

最好不要猜。尝试一些类似下面的调试代码

//un-tested pseudo debugging code

//get the application's routes, using the same 
//technique as the route:cache command
$app = require /path/to/your/laravel/bootstrap/app.php';
$app->make('Illuminate\Contracts\Console\Kernel')->bootstrap();
$routes = $app['router']->getRoutes();

//go through each route
foreach($routes as $route)
{
    //if the route is a closure
    if(is_object($route) && ($route instanceof Closure))
    {
        //use reflection to find out which file the closure is defined in
        $r = new ReflectionFunction($route);
        var_dump($route->getFileName ());
    }

}

这将使您找出导致问题的闭包的定义位置，这应该足以指出问题所在。

Answer 2

事实证明，完全无用的错误消息试图告诉我我有一个 重复的路由 （复制粘贴错误，我有两个匹配相同 uri 的获取路由）。

删除重复项解决了问题。
