我是 Heroku 的新手。有时我一直在尝试在 Heroku 上为 Facebook 部署一个应用程序，但没有看到成功。我试过在互联网上搜索解决方案，但没有找到任何分步指南，所以我在这里提问。

我的 Fb 应用程序代码“index.php”

<?php
session_start();
require_once __DIR__ . '/fbsdk/autoload.php';

$fb = new Facebook\Facebook([
'app_id' => '************',
'app_secret' => '**********',
'default_graph_version' => 'v2.4',]);
 $helper = $fb->getCanvasHelper();
 $permissions = ['email']; 

try {
if (isset($_SESSION['facebook_access_token'])) {
$accessToken = $_SESSION['facebook_access_token'];
} else {
    $accessToken = $helper->getAccessToken();
}
} catch(Facebook\Exceptions\FacebookResponseException $e) {
} catch(Facebook\Exceptions\FacebookSDKException $e) {
}

if (isset($accessToken)) {

if (isset($_SESSION['facebook_access_token'])) {
    $fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
} else {
    $_SESSION['facebook_access_token'] = (string) $accessToken;
    $oAuth2Client = $fb->getOAuth2Client();
    $longLivedAccessToken = $oAuth2Client->getLongLivedAccessToken($_SESSION['facebook_access_token']);
    $_SESSION['facebook_access_token'] = (string) $longLivedAccessToken;
    $fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
}

try {
    $request = $fb->get('/me');
} catch(Facebook\Exceptions\FacebookResponseException $e) {
    if ($e->getCode() == 190) {
        unset($_SESSION['facebook_access_token']);
        $helper = $fb->getRedirectLoginHelper();
        $loginUrl = $helper->getLoginUrl('https://apps.facebook.com/APP_NAMESPACE/', $permissions);
        echo "<script>window.top.location.href='".$loginUrl."'</script>";
        exit;
    }
} catch(Facebook\Exceptions\FacebookSDKException $e) {
}

try {
    $requestPicture = $fb->get('/me/picture?redirect=false&height=300'); 
    $requestProfile = $fb->get('/me');
    $picture = $requestPicture->getGraphUser();
    $profile = $requestProfile->getGraphUser();
} catch(Facebook\Exceptions\FacebookResponseException $e) {
} catch(Facebook\Exceptions\FacebookSDKException $e) {
}

echo "<img src='".$picture['url']."'/>";
} else {
$helper = $fb->getRedirectLoginHelper();
$loginUrl = $helper->getLoginUrl('https://apps.facebook.com/APP_NAMESPACE/');
echo "<script>window.top.location.href='".$loginUrl."'</script>";
 }

“ Composer .json”

 {}

我在 Git Bash 上使用的命令

heroku create AppName
mkdir AppName
cd AppName
git init
git add .
git commit -m "comment"
heroku git:remote -a AppName
git push heroku master

git branch
git commit -am "comment"
git push heroku master

一切顺利，heroku 编译 PHP 文件，部署文件。但是当我直接打开 Fb 应用程序甚至 heroku 应用程序地址时，它会显示一条 **403 Forbidden"消息 fbapp-2.herokuapp.com

目录结构

Buildpacks 设置为 heroku/php
我没有 procfile 或 .htaccess 文件

heroku 日志显示

最佳答案

您收到的错误日志表明您的应用程序不在 Heroku 服务器上的/app 目录中，并且该目录中没有任何内容可供使用。尝试将您的整个应用程序从 Web 根目录转移到/app 目录，看看进展如何，应该可以解决您的问题，如果没有回复更新的错误日志。
