[Laravel4] 短网址之统计每日点击数

使用redis计数，laravel4里面默认使用的是predis，这里我使用的是phpredis库，首先注释掉app/config/app.php里面的Redis的alias

// 'Redis'           => 'Illuminate\Support\Facades\Redis',

实现代码

使用redis的sorted set储存每日的每个链接的点击次数

$config = Config::get('database.redis.default');
with($redis = new Redis)->connect($config['host'], $config['port']);
$redis->zIncrBy(date('Ym:d'), 1, $link->id);

统计数据，取出当天点击数最多的10个链接的id

$redis->zRevRange(date('Ym:d'), 0, 9);

[Laravel4] 短网址之API

我们提供三种格式的API, txt json jsonp

代码

路由

Route::get('short.txt', 'ShortController@txt');
Route::get('short.json', 'ShortController@json');
Route::get('short.jsonp', 'ShortController@jsonp');

控制器

public function txt() {
	$validator = Validator::make(Input::all(), [
				'url' => 'required|max:255|url',
			]);
	if ($validator->fails()) {
		return implode(PHP_EOL, $validator->errors()->all());
	}
	$url = Input::get('url');
	$hash = md5($url);
	$link = Link::whereHash($hash)->first();
	if (!$link)
		$link = Link::create(compact('url', 'hash'));
	$shorten = \Lib\Base62::encode($link->id);
	return 'http://usr.im/' . $shorten;
}

public function json() {
	$resp = [];
	$validator = Validator::make(Input::all(), [
				'url' => 'required|max:255|url',
			]);
	if ($validator->fails()) {
		return ['status' => 'failed', 'message' => $validator->errors()->all()];
	}
	$url = Input::get('url');
	$hash = md5($url);
	$link = Link::whereHash($hash)->first();
	if (!$link)
		$link = Link::create(compact('url', 'hash'));
	$shorten = \Lib\Base62::encode($link->id);
	return ['status' => 'success', 'content' => 'http://usr.im/' . $shorten];
}

public function jsonp() {
	$resp = [];
	Validator::extend('callback', function($attribute, $value, $parameters) {
		return preg_match('/^[A-z_]\w*$/i', $value);
	});
	$validator = Validator::make(Input::all(), [
				'url' => 'required|max:255|url',
				'callback' => 'required|max:255|callback',
			]);
	if ($validator->fails()) {
		return Response::json(['status' => 'failed', 'message' => $validator->errors()->all()])
						->setCallback(Input::get('callback'));
	}
	$url = Input::get('url');
	$hash = md5($url);
	$link = Link::whereHash($hash)->first();
	if (!$link)
		$link = Link::create(compact('url', 'hash'));
	$shorten = \Lib\Base62::encode($link->id);
	return Response::json(['status' => 'success', 'content' => 'http://usr.im/' . $shorten])
					->setCallback(Input::get('callback'));
