Laravel Deploy to Heroku

参考 https://devcenter.heroku.com/articles/getting-started-with-laravel

即可

注意的是，

在使用pgsql的时候，

database.php配置default 一定要修改mysql为pgsql 默认值 即使.env配置设置了pgsql也会报异常，

其余的参考：

<?php

use IlluminateSupportStr;

$DATABASE_URL =
    parse_url("postgres://*****.compute.amazonaws.com:5432/******");

return [

注意pgsql里url和client_encoding

其次代码中的query查询不能使用lower(name) LIKE …. 直接使用name LIKE

然后
heroku run php artisan migrate前执行heroku run php artisan config:cache
