我和我的一些同事得到了net::ERR_SPDY_PROTOCOL_ERROR错误.

我们使用ngnix版本1.8.0.错误不稳定(难以复制),并且Ngnix错误日志没有此错误.

您如何建议我们抓住并解决这个问题？

我试图理解中间件在Laravel 5中是如何工作的.我查看了Middleware Interface并理解我必须实现一个类,它有一个名为"handle"的方法.在"handle"方法中,调用闭包.但我不明白,关闭应该通过什么.什么类会调用我的中间件？它是如何在引擎盖下工作的？可能就像"foreach"一样,所有的中间件都会被轮流调用？ 更新: 我正在尝试实现自己的中间件:

interface Middleware
{
    public function handle($request, Closure $next);
}

class MiddlewareCollection
{
    private $middlewares;
    private $request;

    public function __construct(Array $middlewares, $request)
    {
        $this->middlewares = $middlewares;
        $this->request = $request;
    }

    public function run()
    {
        $this->next(current($this->middlewares), $this->request);
    }

    private function next(Middleware $middleware, $request)
    {
        $middleware->handle($request, function($request) {
        //How can I call the next middleware?
        });

    }
}

class FirstMiddleware implements Middleware
{
    public function handle($request, Closure $next) {
        echo $request.'first ';
        return $next($request);
    }
}

class SecondMiddleware …

我尝试捕获异常，但我仍然收到“致命错误：未捕获的异常 'GuzzleHttp\Exception\ClientException' 和消息 'Client error: 404' in C:\OS\OpenServer\domains\kinopoisk\parser\php\vendor\guzzlehttp\狂饮\src\Middleware.php:69"

我安装了Symfony3框架标准版.我正在尝试打开主页(app.php prod),它加载300-400ms.这是我的探查器信息: 我也用php7.

为什么这么久？
