Register the package with lumen in bootstrap/app.php with the following:

$app->register(HavenShen\Larsign\LarsignServiceProvider::class);

Global usage

To allow Larsign for all your routes, add the HandleLarsign middleware in the $middleware property of app/Http/Kernel.php class:

protected $middleware = [
    // ...
    \HavenShen\Larsign\HandleLarsign::class,
];

Group middleware

If you want to allow Larsign on a specific middleware group or route, add the HandleLarsign middleware to your group:

protected $middlewareGroups = [
    'web' => [
       // ...
    ],

    'api' => [
        // ...
        \HavenShen\Larsign\HandleLarsign::class,
    ],
];

Application route middleware

If you want to allow Larsign on a specific application middleware or route, add the HandleLarsign middleware to your application route:

protected $routeMiddleware = [
    // ...
    'auth.larsign' => \HavenShen\Larsign\HandleLarsign::class,
];

Configuration

The defaults are set in config/larsign.php. Copy this file to your own config directory to modify the values. If you're using Laravel, you can publish the config using this command:

$ php artisan vendor:publish --provider="HavenShen\Larsign\LarsignServiceProvider"

If you're using Lumen, Copy the configuration larsign.php from vendor/havenshen/larsign/config/larsign.php to your config/ directory

return [
    /*
     |--------------------------------------------------------------------------
     | Larsign
     |--------------------------------------------------------------------------
     |
     */
    'headerName' => env('LARSIGN_HEADER_NAME', 'Larsign'),
    'accessKey' => env('LARSIGN_ACCESS_KEY', ''),
    'secretKey' => env('LARSIGN_SECRET_KEY', ''),
];

Add api route in routes/api.php Copy this.

Route::middleware(['auth.larsign'])->group(function () {
    Route::get('/larsign', function () {
    return [
        'message' => 'done.'
    ]);
});

or

Route::get('/larsign', function () {
    return [
        'message' => 'done.'
    ];
})->middleware('auth.larsign');

Client

Generate Larsign signatures

1. Assume the following management credentials:

AccessKey = "test"
SecretKey = "123456"

2. Call interface address:

url = "https://larsign.dev/api/v1/test?page=1"

3. The original string to be signed:

note: the time-stamping followed by a newline [currenttime + voucher valid seconds]

signingStr = "/api/v1/test?page=1\n1510986405"

4. Base64 url safe encode:

signingStrBase64UrlSafeEncode = "L2FwaS92MS90ZXN0P3BhZ2U9MQoxNTEwOTg2NDY1"

5. hmac_sha1 carries SecretKey encryption then base64 url safe encode:

sign = "MLKnFIdI-0TOQ4mHn5TyCcmWACU="

6. The final administrative credentials are:

note: stitching headerName Space AccessKey:sign:signingStrBase64UrlSafeEncode

larsignToken = "Larsign test:MLKnFIdI-0TOQ4mHn5TyCcmWACU=:L2FwaS92MS90ZXN0P3BhZ2U9MQoxNTEwOTg2NDY1"

7. Add http header:

note: header key in config/larsign.php -> headerName

Larsign:Larsign test:MLKnFIdI-0TOQ4mHn5TyCcmWACU=:L2FwaS92MS90ZXN0P3BhZ2U9MQoxNTEwOTg2NDY1
