使用未命名为laravel 5.3的供应商

There is a vendor that I want to use that was originally created for Symphony and it isnt namespaced into Laravel, I'm not too sure on how to make it work.

Here is the package: https://github.com/caponica/AmazonMwsComplete

I read somewhere that I would have to add psr-0 into composer and i already have the psr-4 default data in composer so i added

"psr-0": {
          "MWS\\": "caponica/amazon-mws-complete"
        },

the MWS\ i just made up since i wasnt too sure what to do and the other portion is the vendor folders, figured thats what i needed.

so when i tried to call the class into routes for testing i tried

use MWS\CaponicaAmazonMwsComplete\AmazonClient\MwsProductClient;

and it keeps saying that the MwsProductClient class isnt found.

It happened because you are trying to use wrong path and namespace. Accrording to the source code of package you are trying to use the namespace you want to load is namespace CaponicaAmazonMwsComplete\AmazonClient; So you need to include this into you composer.json file: "psr-0": { "CaponicaAmazonMwsComplete\\": "caponica/amazon-mws-complete/src" },

I'm not 100% sure but it should work. Don't forget to run composer dump-autoload before using.

If it doesn't work add a comment here and I will check it again.

UPDATE: So I managed it to work using PSR-4 autoload:

"psr-4": {
      "App\\": "app/",
      "CaponicaAmazonMwsComplete\\": "vendor/caponica/amazon-mws-complete/src/CaponicaAmazonMwsComplete",
      "AmazonPhpClientLibrary\\": "vendor/caponica/amazon-mws-complete/src/AmazonPhpClientLibrary"
    }

But note that this library is quite outdated and it's documentation doesn't fits it's code.
