Laravel 如何在lumen 5.2上使用Illumb\Session\Middleware\StartSession:：class

我得到了这个错误：

BindingResolutionException in Container.php line 839:
Unresolvable dependency resolving 
[Parameter #0 [ <required> $app ]] in class Illuminate\Support\Manager

$app->middleware([
 Illuminate\Session\Middleware\StartSession::class,
]);

在添加

StartSession

中间件之前，将此依赖项注入容器：

$app->bind(Illuminate\Session\SessionManager::class, function ($app) {
    return new Illuminate\Session\SessionManager($app);
});

$app->middleware([
    Illuminate\Session\Middleware\StartSession::class,
]);

以下是在Lumen（在Lument 5.4上测试）中激活会话所需完成的工作的概述：

config/session.php

// Load session config (otherwise it won't be loaded)
$app->configure('session');

// Add `Session` middleware
$app->middleware(Illuminate\Session\Middleware\StartSession::class);

// Add `SessionServiceProvider`
$app->register(Illuminate\Session\SessionServiceProvider::class);

// fix `BindingResolutionException` problem
$app->bind(Illuminate\Session\SessionManager::class, function ($app) {    
    return $app->make('session');
});

从Laravel repo下载会话配置

bootstrap/app.php

// Load session config (otherwise it won't be loaded)
$app->configure('session');

// Add `Session` middleware
$app->middleware(Illuminate\Session\Middleware\StartSession::class);

// Add `SessionServiceProvider`
$app->register(Illuminate\Session\SessionServiceProvider::class);

// fix `BindingResolutionException` problem
$app->bind(Illuminate\Session\SessionManager::class, function ($app) {    
    return $app->make('session');
});

---

之后，您可以使用控制器中的

app（'session'）

访问会话。
