我的应用程序流程如下所示：

1. 启动应用
2. 在浏览器（Chrome）中打开Spotify的“允许访问应用程序”页面，
3. 用户授予应用权限，并重定向到https://appurl.com/spotify-callback/，
4. 该网址是深层链接，因此我的应用现在可以再次打开，
5. 现在，深层链接插件应该匹配/spotify-callback/并打开名为SpotifyCallbackPage的页面，但是我得到了错误console.error: Got a deeplink that didn't match

我的深层链接代码如下：

deeplinks.route({
                '/spotify-callback/': SpotifyCallbackPage
            }).subscribe((match) => {
                // match.$route - the route we matched, which is the matched entry from the arguments to route()
                // match.$args - the args passed in the link
                // match.$link - the full link data
                console.log('Successfully matched route', match);
            }, (nomatch) => {
                // nomatch.$link - the full link data
                console.error('Got a deeplink that didn\'t match');
                console.log(nomatch);
            }); …

我正在使用Docker Compose来构建我的第一台Docker机器.我想安装Docker有PHP-FPM 7,Nginx和MySQL(使用MariaDB).

这是我的docker-compose.yml

version: '2'
services:
nginx:
image: nginx:latest
ports:
  - "80:80"
volumes:
  - ./nginx/site.conf:/etc/nginx/conf.d/default.conf
  - ./logs/nginx-error.log:/var/log/nginx/error.log
  - ./logs/nginx-access.log:/var/log/nginx/access.log
  - ./public:/usr/share/nginx/html
links:
  - phpfpm

phpfpm:
image: php:7-fpm
volumes:
  - ./public:/usr/share/nginx/html
  - ./logs/log.conf:/usr/local/etc/php-fpm.d/zz-log.conf

mariadb:
image: mariadb
environment:
  MYSQL_ROOT_PASSWORD: admin
  MYSQL_DATABASE: admin
  MYSQL_USER: admin
  MYSQL_PASSWORD: admin
volumes:
 - ./database:/var/lib/mysql

Docker正确启动但是当我尝试使用mysql_connect连接到index.php中的数据库时,我得到错误:

致命错误:未捕获错误:在/usr/share/nginx/html/index.php:7中调用未定义函数mysql_connect()堆栈跟踪:#us {/}////////////////////////在第7行

这是我的index.php

<?php
 $username = "admin";
 $password = "admin";
 $hostname = "localhost";

 //connection to the database
 $dbhandle = mysql_connect($hostname, $username, $password)
   or die("Unable to connect to MySQL");
 echo "Connected to …
