.env配置: DATABASE_URL="mysql://root:123456@127.0.0.1:端口/数据库名称?serverVersion=5.7&charset=utf8" 创建数据库 php bin/console doctrine:database:create

php composer.phar require php-amqplib/php-amqplib 使用消息队列

php composer.phar require symfony/messenger 可以使用messenger

php composer.phar require symfony/orm-pack 可以使用doctrine

php composer.phar require symfony/maker-bundle --dev 可以使用如下命令： php bin/console make:controller DefaultController

文件默认放在：/usr/lib/systemd/system/messenger-worker.service 输入：systemctl enable messenger-worker.service命令后，会自动将文件放在系统服务目录下

1.创建机器人 @BotFather /newbot - create a new bot 2.查看群组id 在群组发个消息后，打开：https://api.telegram.org/TOKEN/getUpdates 3.查看自己的信息 https://api.telegram.org/TOKEN/getMe 4.给群组或者个人发送消息 https://api.telegram.org/TOKEN/sendMessage?text=hello&chat_id=chat_id 5.注册回调 $url = 'https://api.telegram.org/' . token . '/setWebhook'; $data = [ 'url' => 'https://www.xxx.com/bot/callback', ]; $result = $this->curl_post($url, $data);

在react项目目录下，打开cmd，输入： openssl req -x509 -newkey rsa:2048 -keyout keytmp.pem -out cert.pem -days 365 第二步，输入： openssl rsa -in keytmp.pem -out key.pem 打开：package.json 修改： "start": "export HTTPS=true&&SSL_CRT_FILE=cert.pem&&SSL_KEY_FILE=key.pem react-scripts start", 然后cmd输入：set HTTPS=true&&yarn start 启动react ，chrome会提示证书无效，在chrome中导入证书到信任区域后，重新打开chrome，重新打开https://localhost:3000 此时证书正常！
