Contao api bundle

A generic API with restricted access to provide access to 3rd party applications.

Login /api/login/member or api/login/user

Login is done via symfony guard authenticator in combination with contao members tl_member or users tl_user. After successful login a volatile token (default: 24 hours) will be returned that is used for any api and must be provided within request headers Authorization: Bearer {{token}};

# test login (with contao front end member)
curl --user username:password -H "Content-Type: application/json" -X POST http://domain.tld/api/login/member

# example response on success
{
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VybmXtZSI6ImRpZ2l0YWxlc0BoZWltcmljaA1oYW5ub3QuZGUiLCJpYXQiOjE1MzY4NTYwMDMsImV4cCI6MTUzNjk0MjQwM30.trp-1NgYgXGfHYdE3dlQ8awE8aXUWL-RfBQyfWm2Hz0"
}

# test login (with contao back end member)
curl --user username:password -H "Content-Type: application/json" -X POST http://domain.tld/api/login/user

# example response on success
{
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VybmXtZSI6ImRpZ2l0YWxlc0BoZWltcmljaA1oYW5ub3QuZGUiLCJpYXQiOjE1MzY4NTYwMDMsImV4cCI6MTUzNjk0MjQwM30.trp-1NgYgXGfHYdE3dlQ8awE8aXUWL-RfBQyfWm2Hz0"
}

Create an app with an custom api key

Visit your contao backend at http://domain.tld/contao?do=api_apps and create your first app. Access can be restricted for member or user groups. Admin users tl_user will have access to every api by default. For each request beside the login routes you must provide the generated API key as GET Parameter.

Resource /api/resource/{resource_alias}

To add your custom resource, simply add an service within your bundles or app services.yml:

services:
	my.api.resource.my_resource:
		class: MyApi\Resource\MyResource
		arguments:
              - "my_resource"
		tags:
		- { name: huh.api.resource, alias: my_resource}

And register your resource configuration within your bundles or app config.yml:

huh:
  api:
    resources:
      - {name: my_resource, type: entity_resource, modelClass: "MyResourceModel", verboseName: my_resource}

To get your config.yml loaded properly, your Plugin class must implement the interface Contao\ManagerPlugin\Config\ExtensionPluginInterface:

namespace MyApi\ContaoManager;

use Contao\ManagerPlugin\Config\ContainerBuilder;
use Contao\ManagerPlugin\Config\ExtensionPluginInterface;
use HeimrichHannot\UtilsBundle\Container\ContainerUtil;

class Plugin implements ExtensionPluginInterface
{

    /**
     * {@inheritdoc}
     */
    public function getExtensionConfig($extensionName, array $extensionConfigs, ContainerBuilder $container)
    {
        return ContainerUtil::mergeConfigFile(
            'huh_api',
            $extensionName,
            $extensionConfigs,
            __DIR__.'/../Resources/config/config.yml'
        );
    }

Do not forget to clear the symfony cache afterwards!

Now you are able to access your resource through /api/resource/my_resource.

# test access to my_resource (provide your token from user or member login and your api key)
curl --header "Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VybmXtZSI6ImRpZ2l0YWxlc0BoZWltcmljaA1oYW5ub3QuZGUiLCJpYXQiOjE1MzY4NTYwMDMsImV4cCI6MTUzNjk0MjQwM30.trp-1NgYgXGfHYdE3dlQ8awE8aXUWL-RfBQyfWm2Hz0" -H "Content-Type: application/json" -X GET http://domain.tld/api/resource/my_resource?key=<api-key>

Now you are able to access crud functionality by using the related HTTP method:

Path	HTTP-Method	Resource-Method (Mapping)
/api/resource/my_resource	POST	create() new resource
/api/resource/my_resource/23	PUT	update() existing resource with id 23
/api/resource/my_resource	GET	list() all resources
/api/resource/my_resource/23	GET	show() existing resource with id 23
/api/resource/my_resource/23	DELETE	delete() existing resource with id 23

# test create() new resource
curl --header "Authorization: Bearer <login-token>" -H "Content-Type: application/json" -X POST -d "{"title":"My test title", "published":true}" http://domain.tld/api/resource/my_resource?key=<api-key>

# test update() existing resource
curl --header "Authorization: Bearer <login-token>" -H "Content-Type: application/json" -X PUT -d "{"title":"My new test title", "published":false}" http://domain.tld/api/resource/my_resource/23?key=<api-key>

# test list() all resources
curl --header "Authorization: Bearer <login-token>" -H "Content-Type: application/json" -X GET http://domain.tld/api/resource/my_resource?key=<api-key>

# test show() existing resource
curl --header "Authorization: Bearer <login-token>" -H "Content-Type: application/json" -X GET http://domain.tld/api/resource/my_resource/23?key=<api-key>

# test delete() existing resource
curl --header "Authorization: Bearer <login-token>" -H "Content-Type: application/json" -X DELETE http://domain.tld/api/resource/my_resource/23?key=<api-key>
