Lumen Micro Framework => php artisan key：generate

Question

I'm trying out the PHP micro Framework Lumen (from Laravel).

One of my first steps was to look into the .env.example file and make a copy of it to have my .env file. There is a variable APP_KEY just like there is in Laravel. Now I tried out the simple command php artisan key:generate to get my new key But I ran into the following error message:

[InvalidArgumentException] There are no commands defined in the "key" namespace.

Does some one know how I can generate keys for Lumen?

Update with solution

So I found my favorite solution for this problem. On the command line (Linux) I run php -r "echo md5(uniqid()).\" \";" what gives me something like this 7142720170cef01171fd4af26ef17c93.

If you are going to use Lumen more often, you may want to create an alias in your .bashrc, which is located in your home directory /home/USERNAME. To do so, you can open the file with nano ~/.bashrc or vi ~/.bashrc and copy the following alias at the end of the file, alias phpkey='php -r "echo md5(uniqid()).\" \";"'. Now you can use the command phpkey which will give you a 32 character long random string :)

Answer 1

The Laravel command is fairly simple. It just generates a random 32 character long string. You can do the same in Lumen. Just temporarily add a route like this:

$router->get('/key', function() {
    return str_random(32);
});

Then go to /key in your browser and copy paste the key into your .env file.
Afterwards remove the route.

Obviously you could also use some random string generator online. Like this one
