初探 Swoole -- 用 Swoole 啟動一個 hello world

內(nèi)存的妙用 -- PHP終于可以 vs JAVA啦

初級應(yīng)用 -- 實現(xiàn)用戶登錄 [撰寫中]

展望 -- Swoole 的局限性分析及我個人的期待 [撰寫中]

上節(jié)內(nèi)存的妙用 -- PHP終于可以 vs JAVA啦中, 我們了解了 Swoole 的MYSQL數(shù)據(jù)庫 CURD 操作, 這節(jié)我們用 MongoDB來做演示.

環(huán)境說明:

MacOS X El Captain 10.11.6

PHP 7.0.8 with MongoDB support

MongoDB 1.1.8

CSS框架 Bootstrap3

首先, 我們來做個用戶登錄頁面
/tpl/login.html

    
        
    
    
        

            
Login
            Username: 

            Password: 

            Submit
        
    

PHP代碼

我們引入MongoDB

selectDatabase($dbname);
            self::$dbname = $dbname;
        }
        return self::$db;
    }

    public static function id($id){
        return new MongoDBBSONObjectID($id);
    }

    public function __call($name, $arguments){
        return self::$db->selectCollection(self::$dbname, $name);
    }
}

Swoole啟動代碼

_GLOBAL_SESSION = [];
$http->mongo      = Mongo::instance("db");
$http->db         = new stdClass();

# 使用預(yù)加載, 提前將用戶數(shù)據(jù)加載到內(nèi)存. 登錄都無需網(wǎng)絡(luò)/磁盤IO
if("user"){
    echo "加載用戶數(shù)據(jù)
";
    $http->db->user = [];
    $users = $http->mongo->user->find([]);
    foreach ($users as $i => $user) {
        $user["_id"] = $user["_id"]->__toString();
        $http->db->user[$user["username"]] = $user;
    }
    echo "用戶數(shù)據(jù)加載完成

";
    unset($user);unset($users);
}

主邏輯：

on("request", function(swoole_http_request $req, swoole_http_response $res) use($http) {


    if (!isset($req->cookie) || !isset($req->cookie["sid"]) || !$req->cookie["sid"]) {
        $req->cookie["sid"] = md5(password_hash(time().mt_rand(100000, 999999), 1));
        $res->cookie("sid", $req->cookie["sid"], time() + 60 * 60 * 24 * 365 * 10, "/", "", false, true);
    }

    $_SESS_ID = $req->cookie["sid"];
    if (!is_array($http->_GLOBAL_SESSION[ $_SESS_ID ])) $http->_GLOBAL_SESSION[ $_SESS_ID ] = [];
    $_SESSION = &$http->_GLOBAL_SESSION[ $_SESS_ID ];

    if ( $req->server["request_uri"] == "/" ) {
        $res->status(302);
        $res->header("Location", "/login/");
        $res->end();
        return;
    }else
    if ( $req->server["request_uri"] == "/login/" ) {
        if ($_SESSION["user"]) {
            $res->status(302);
            $res->header("Location", "/i/");
            $res->end();
            return;
        }

        $html = file_get_contents(dirname(__FILE__)."/tpl/"."login.html");
        $res->write($html);
        $res->end();

        unset($html);
        return;
    }else
    if ( $req->server["request_uri"] == "/dologin/" ) {
        $user = $http->db->user[$req->post["username"]];
        if (!$user || !password_verify($req->post["password"], $user["password"])) {
            $res->write("bad_account_or_password");
            $res->end();
            return;
        }
        $_SESSION["user"]           = $user;
        unset($user);

        $res->status(302);
        $res->header("Location", "/vul/");
        $res->end();
        return;
    }else
    if ( $req->server["request_uri"] == "/i/" ) {
        $res->write("You currently logged in as".$_SESSION["user"]["username"]);
        $res->end();
        return;
    }

    $res->status(404);
    $res->end();
    return;
});
