Middleware to block referrer spammers using [matomo/referrer-spam-blacklist](https://github.com/matomo-org/referrer-spam-blacklist). It returns a `403` response if the url host in the `Referer` header is in the blacklist.

Requirements
------------

[](#requirements)

- PHP >= 7.2
- A [PSR-7 http library](https://github.com/middlewares/awesome-psr15-middlewares#psr-7-implementations)
- A [PSR-15 middleware dispatcher](https://github.com/middlewares/awesome-psr15-middlewares#dispatcher)

`ext-intl` PHP extension is recommended otherwise [symfony/polyfill-intl-idn](https://github.com/symfony/polyfill-intl-idn) is used.

Installation
------------

[](#installation)

This package is installable and autoloadable via Composer as [middlewares/referrer-spam](https://packagist.org/packages/middlewares/referrer-spam).

```
composer require middlewares/referrer-spam
```

Usage
-----

[](#usage)

By default, use `matomo/referrer-spam-blacklist` as a list of spammers

```
$spam = new Middlewares\ReferrerSpam();
```

But you can configure a custom spam list if you don't want to use the default:

```
$spammers = [
    'http://www.0n-line.tv',
    'http://холодныйобзвон.рф',
];

$spam = new Middlewares\ReferrerSpam($spammers);
```

Optionally, you can provide a `Psr\Http\Message\ResponseFactoryInterface` as the second argument to create the error responses (`403`). If it's not defined, [Middleware\\Utils\\Factory](https://github.com/middlewares/utils#factory) will be used to detect it automatically.

```
$responseFactory = new MyOwnResponseFactory();

$spam = new Middlewares\ReferrerSpam($spammers, $responseFactory);
```
