目标[Illuminate\Contracts\Routing\ResponseFactory]不可实例化

Question

我正在尝试返回如下响应：

return response()->json(['name' => 'Abigail', 'state' => 'CA']);

然而，我得到了错误：

Target [Illuminate\Contracts\Routing\ResponseFactory] is not instantiable.

有什么想法吗？

这是我的composer.json：

Answer 1

我仍然会在2020年遇到这个错误。以下是@sunben提供的解决方案的更新版本：

在bootstrap/app.php，中，取消注释以下行

$app->register(App\Providers\AppServiceProvider::class);

然后在app\Providers\AppServiceProvider.php，更新寄存器方法中添加：

$this->app->singleton(\Illuminate\Contracts\Routing\ResponseFactory::class, function() {
    return new \Laravel\Lumen\Http\ResponseFactory();
});

可能会迟到，但找到了解决方案。

在bootstrap/app.php，中，取消注释以下行

$app->register(App\Providers\AppServiceProvider::class);

然后在app\Providers\AppServiceProvider.php，更新寄存器方法中添加：

public function register()
{
    $this->app->singleton('Illuminate\Contracts\Routing\ResponseFactory', function ($app) {
        return new \Illuminate\Routing\ResponseFactory(
            $app['Illuminate\Contracts\View\Factory'],
            $app['Illuminate\Routing\Redirector']
        );
    });
}

Answer 3

尝试像这样的public function register() { $this->app->singleton(\Illuminate\Contracts\Routing\ResponseFactory::class, function() { return new \Laravel\Lumen\Http\ResponseFactory(); }); $this->app->bind(\Illuminate\Contracts\Routing\UrlGenerator::class, function ($app) { return new \Laravel\Lumen\Routing\UrlGenerator($app); }); }
