It can distribute callbacks to several systems, for example: ``` proxy.example.com/paypal-dev/postBack => dev1.example.com/paypal/postBack dev2.example.com/paypal/postBack dev3.example.com/paypal/postBack ``` The first successful response is returned. If no response was successful (HTTP status code 200), the last response is returned. If it is used for dev systems, only the proxy must be made accessible from outside by the third party, instead of all target systems. Installation ------------ [](#installation) 1. Create project via composer ``` composer create-project integer-net/callback-proxy ``` 2. Set up web server with document root in `public`. Configuration ------------- [](#configuration) 1. Copy [`config.php.sample`](config.php.sample) to `config.php`. 2. Adjust the `proxy/targets` configuration, e.g.: ``` 'proxy' => [ 'targets' => [ 'paypal-dev' => [ 'https://dev1.example.com/paypal/', 'https://dev2.example.com/paypal/', ], ], ], ``` This example routes `/paypal-dev/*` to `https://dev1.example.com/paypal/*` and `https://dev2.example.com/paypal/*`. Advanced Configuration ---------------------- [](#advanced-configuration) Instead of a plain URI string, each target can also be configured with additional options: ``` [ 'uri' => 'https://dev1.example.com/paypal/', 'basic-auth' => 'username:password', ] ``` - **uri** (required) - the base URI - **basic-auth** - HTTP basic authentication in the form "username:password" The default dispatcher strategy is to dispatch the request to all targets and return the first successful (2xx) response. You can choose a different strategy in `config.php`: ``` 'proxy' => [ 'strategy' => \IntegerNet\CallbackProxy\DispatchStrategy\DispatchAllReturnFirstSuccess::class, ] ``` **Available Strategies:** - `\IntegerNet\CallbackProxy\DispatchStrategy\DispatchAllReturnFirstSuccess::class` - the default strategy, see above - `\IntegerNet\CallbackProxy\DispatchStrategy\StopOnFirstSucces::class` - returns the first successful (2xx) response, stops dispatching further targets You can implement your own strategies, by implementing the `\IntegerNet\CallbackProxy\DispatchStrategy` interface. Change log ---------- [](#change-log) Please see [CHANGELOG](CHANGELOG.md) for more information on what has changed recently. Testing ------- [](#testing) ``` composer test ``` Runs unit tests, mutation tests and static analysis ``` php -S localhost:9000 -t public ``` Starts the proxy locally on port 9000 for manual testing. Needs a valid configuration in `config.php`. As a generic target URI, you can use `https://httpbin.org/anything/` Contributing ------------ [](#contributing) Please see [CONTRIBUTING](CONTRIBUTING.md) for details.
