Laravel:函数Illuminate \ Support \ Manager :: createDriver()的参数太少 [英] Laravel: Too few arguments to function Illuminate\Support\Manager::createDriver()

问题描述

我尝试使用mailtrap和Laravel 5.4测试电子邮件.我收到此错误:

I try to test emails with mailtrap and Laravel 5.4. I get this error:

类型错误:函数参数太少 Illuminate \ Support \ Manager :: createDriver()，传入0 C:\ Users *** \ Documents \ www \ *** \ backend \ vendor \ laravel \ framework \ src \ Illuminate \ Support \ Manager.php在第88行，期望值恰好为1

Type error: Too few arguments to function Illuminate\Support\Manager::createDriver(), 0 passed in C:\Users***\Documents\www\***\backend\vendor\laravel\framework\src\Illuminate\Support\Manager.php on line 88 and exactly 1 expected

我已经尝试过config:cache，config:clear等.

这是我回声env('MAIL_DRIVER')

smtp

smtp

这是我的.env文件

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io 
MAIL_PORT=2525 
MAIL_USERNAME=*********
MAIL_PASSWORD=*********
MAIL_ENCRYPTION=null

这是我的邮件功能:

Mail::send('email.verify', compact('validation_code'), function($message) {
    $message->to(Input::get('email'), Input::get('username'))
        ->subject('Verify your email address');
});

有什么想法吗?

非常感谢:)

推荐答案

我相信，如果您没有在.env文件中设置APP_KEY，则会发生这种情况，因此，如果您没有.APP文件，请运行php artisan key:generate.

I believe this happens if you do not have the APP_KEY set in a .env file, so run php artisan key:generate if you do not have one.
