README

Make requests to the HNG CRS api easily.

How to use basically

Pull in the package from composer "neo/crs-request":"1.*". Thats all. A sample implementation is below.

<?php

// Helper functions.... you can implement this however you want...
function saveCrsApiSession(array $session) {
    $path = 'path/to/storage/accesstoken.txt';
    file_put_contents($path, json_encode($session));
}

function getCrsApiSession() {
    $path = 'path/to/storage/accesstoken.txt';
    if (file_exists($path)) {
        return json_decode(file_get_contents($path), true);
    }

    return [];
}


// Using Lumen Router...
try {

    // Configuration details...
    $config  = [
        'base_url'      => 'http://crsapi.dev',
        'client_id'     => '12345',
        'client_secret' => 'SUPER_SECRET_CLIENT_SECRET',
        'scopes'        => ['scope1', 'scope2'],
    ];

    // Use Guzzle...
    $guzzle  = new HNG\Http\GuzzleRequest($config);

    // Get the stored session details and set it to the request class,
    // This is to avoid multiple calls to the service for authentication.
    $previouslyStoredSession = getCrsApiSession();

    // Create a request instance...
    $request = new HNG\Http\Request($guzzle, $config, $previouslyStoredSession);

    $bookings = $request->get('/bookings');

    saveCrsApiSession((array)$request->getSession());
} catch (\Exception $e) {
    // This should not really happen except your credentials are wrong...
    throw $e;
}

Debugging

Everytime an error occurs, the error details are logged in the log directory of your storage path set above. Here is an example of the logged information:
