PHP Heroku - 错误代码 H10（状态 503）

Question

我在 Heroku 上部署了一个简单的 PHP 应用程序，其中仅包含一个（PHP）脚本用于我的源代码。 我决定在单独的 PHP 脚本中编写 function。 在此之后，我收到403 Forbidden Error并且此消息显示在我的应用程序的 url 上： Forbidden You don't have permission to access / on this server 。 因此，我创建了一个名为Procfile的文本文档，没有任何扩展名，并在其中发布了以下内容： web: vendor/bin/heroku-php-apache2 web/ 。

但是，现在我在heroku logs上收到以下错误：

2018-04-10T09:09:09.853483+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=POST path="/" host=************.herokuapp.com request_id=************ fwd="************" dyno= connect= service= status=503 bytes= protocol=https
2018-04-10T09:09:56.037642+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=************.herokuapp.com request_id=************ fwd="************" dyno= connect= service= status=503 bytes= protocol=https

并且在我的应用程序的 url 处显示以下消息：

Application error
An error occurred in the application and your page could not be served. 
If you are the application owner, check your logs for details.

我在 Heroku 上的（主要）PHP 脚本从 Dialogflow 接收/托管一个 webhook，并向它返回从数据库检索的一些信息。 它看起来像这样：

<?php

$dbServername = '******************';
$dbUsername = '******************';
$dbPassword = '******************';
$dbName = '******************';
$conn = mysqli_connect($dbServername, $dbUsername, $dbPassword, $dbName);

header('Content-Type: application/json');
$method = $_SERVER['REQUEST_METHOD'];

if ($method == 'POST') {
    $requestBody = file_get_contents('php://input');
    $json = json_decode($requestBody);

    $action = $json->result->action;
    $first_name = $json->result->contexts[0]->parameters->{'given-name'};
    $last_name = $json->result->contexts[0]->parameters->{'last-name'};
    $lifespan = $json->result->contexts[0]->lifespan;

    $sql = "SELECT * FROM family WHERE name LIKE '%$first_name%$last_name%';";
    $result = mysqli_query($conn, $sql);
    $resultCheck = mysqli_num_rows($result);
    if ($resultCheck > 0) {
        while ($row = mysqli_fetch_assoc($result)) {
            $person = $row;
        }

        switch ($action) {
            case 'Name':
                $speech = "$first_name is my" . $person["name"] . ".";
                break;
            case 'Location':
                $speech = "$first_name is living in {$person["location"]}.";
                break;
            default:
                $speech = "Please ask me something more relevant to my family";
                break;
        }
    } else {

        $speech = "Sorry, $first_name $last_name is not a member of my family.";
    }

    $response = new \stdClass();
    $response->speech = $speech;
    $response->displayText = $speech;
    $response->source = "agent";
    echo json_encode($response);
} else {
    echo "Method not allowed";
}
?>

为什么我会收到此错误，我该如何解决？

我不知道这是否相关，但是当我在终端输入git push heroku master时，我也收到以下警告：

remote:  !     WARNING: Your Composer vendor dir is part of your Git repository.
remote:        This directory should not be under version control; only your

我通过检查根目录是否存在解决了同样的问题你需要检查你Procfile
