Laravel 5 Application Key
提问by Raham
I am new to Laravel. I just started it tonight. Actually, I have the following code:
我是 Laravel 的新手。我今晚刚开始。实际上，我有以下代码：
'key' => env('APP_KEY', 'SomeRandomString'),
In xampp/htdocs/laravel/blog/config/app.php.
I want to change this key to 32-bit by cmd as:
在xampp/htdocs/laravel/blog/config/app.php 中。
我想通过 cmd 将此密钥更改为 32 位：
xampp\htdocs\laravel/blog>php artisan key:generate
It generates the key but could not replace/update in xampp/htdocs/laravel/blog/config/app.php.
它生成密钥但无法替换/更新xampp/htdocs/laravel/blog/config/app.php。

This line in your app.php, 'key' => env('APP_KEY', 'SomeRandomString'),, is saying that the key for your application can be found in your .envfile on the line APP_KEY.
这条线在你的app.php，'key' => env('APP_KEY', 'SomeRandomString'),被说为你的应用的关键可以在找到.env就行了文件APP_KEY。
Basically it tells Laravel to look for the key in the .envfile first and if there isn't one there then to use 'SomeRandomString'.
基本上它告诉 Laravel.env首先在文件中查找密钥，如果没有，则使用'SomeRandomString'.
When you use the php artisan key:generateit will generate the new key to your .envfile and not the app.phpfile.
当您使用php artisan key:generate它时，它将为您的.env文件而不是app.php文件生成新密钥。
As kotapeter said, your .envwill be inside your root Laravel directory and may be hidden; xampp/htdocs/laravel/blog
正如 kotapeter 所说，你.env将在你的 Laravel 根目录中并且可能被隐藏；xampp/htdocs/laravel/博客

You can generate a keyby the following command:
您可以key通过以下命令生成一个：
php artisan key:generate
The key will be written automatically in your .envfile.
密钥将自动写入您的.env文件中。
APP_KEY=YOUR_GENERATED_KEY
If you want to see your keyafter generation use --showoption
如果您想查看您的key后代使用--show选项
php artisan key:generate --show
Note: The .envis a hidden file in your project folder.
注意：这.env是项目文件夹中的隐藏文件。

Just as another option if you want to print only the key (doesn't write the .env file) you can use:
作为另一个选项，如果您只想打印密钥（不写入 .env 文件），您可以使用：
php artisan key:generate --show

From the line
从线
'key' => env('APP_KEY', 'SomeRandomString'),
APP_KEYis a global environment variable that is present inside the .envfile.
APP_KEY是存在于.env文件中的全局环境变量。
You can replace the application key if you trigger
如果触发，您可以替换应用程序密钥
php artisan key:generate
command. This will always generate the new key.
命令。这将始终生成新密钥。
The output may be like this:
输出可能是这样的：
Application key [Idgz1PE3zO9iNc0E3oeH3CHDPX9MzZe3] set successfully.
Application key [base64:uynE8re8ybt2wabaBjqMwQvLczKlDSQJHCepqxmGffE=] set successfully.
Base64 encoding should be the default in Laravel 5.4
Base64 编码应该是 Laravel 5.4 中的默认编码
Note that when you first create your Laravel application, key:generate is automatically called.
请注意，当您第一次创建 Laravel 应用程序时，会自动调用 key:generate。
If you change the key be aware that passwords saved with Hash::make()will no longer be valid.
如果您更改密钥，请注意保存的密码Hash::make()将不再有效。

For me the problem was in that I had not yet ran composer updatefor this new project/fork. The command failed silently, nothing happened.
对我来说，问题在于我还没有composer update为这个新项目/fork跑。命令无声无息地失败了，什么也没发生。
After running composer updateit worked.
运行composer update后就成功了。
