ajax + php + Controller 控制所有后台函数调用

好久没有来这边发布代码了

总共分成3大部分来完成php的ajax调用逻辑,以下是大致的结构

第一部分：ajax请求：主要是action这个参数，LoginController是php的类名，login是LoginController这个类中的函数名

$('#submit').on('click', <span>function</span><span> (e) {        e.stopPropagation();        $.ajax({            url: </span>"../../controllers/Controller.php"<span>,            data: {                action: </span>"LoginController/login"<span>,                username: username,                password: password            },            dataType: </span>"text"<span>,            type: </span>'POST'<span>,            timeout: </span>10000<span>,            error: </span><span>function</span><span> () {                alert(</span>"服务器超时"<span>);            },            success: </span><span>function</span><span> (data) {                    alert(data);            }        });    });</span>

第二部分：Controller.php，这个文件是调用其他具体的功能类的控制器，起到枢纽作用，主要是通过反射来实现

<?<span>php</span><span>if</span> (!<span>empty</span>(<span>$_REQUEST</span>['action'<span>])) {    </span><span>try</span><span> {        </span><span>$action</span> = <span>explode</span>('/', <span>$_REQUEST</span>['action'<span>]);        </span><span>$class_name</span> = <span>$action</span>[0<span>];        </span><span>$method_name</span> = <span>$action</span>[1<span>];        </span><span>require</span><span>$class_name</span> . '.php'<span>;        </span><span>$class</span> = <span>new</span> ReflectionClass(<span>$class_name</span><span>);        </span><span>if</span> (<span>class_exists</span>(<span>$class_name</span><span>)) {            </span><span>if</span> (<span>$class</span>->hasMethod(<span>$method_name</span><span>)) {                </span><span>$func</span> = <span>$class</span>->getmethod(<span>$method_name</span><span>);                </span><span>$instance</span> = <span>$class</span>-><span>newInstance();                </span><span>$func</span>->invokeArgs(<span>$instance</span>, <span>array</span>(<span>$_REQUEST</span><span>));                </span><span>$result</span> = <span>$instance</span>-><span>getResult();                </span><span>echo</span><span>$result</span><span>;            }        }    } </span><span>catch</span> (<span>Exception</span><span>$exc</span><span>) {        </span><span>e<strong>+本文来源gao@daima#com搞(%代@#码网</strong><pre>搞代gaodaima码

cho$exc->getTraceAsString(); }}?>

第三部分：LoginController.php,这个文件是具体的功能类

<?<span>php</span><span>class</span><span> LoginController {　　<br /><span>private </span>$result;<br /></span><span>function</span><span> LoginController() {        </span><span>//</span><span>初始化数据库连接等参数</span><span>    }    </span><span>function</span> login(<span>$args</span><span>) {       </span><span>//</span><span>具体的登录逻辑</span><span>    }    </span><span>function</span><span> getResult() {        </span><span>return</span><span>$this</span>-><span>result;    }}</span>?>

以上就介绍了ajax + php + Controller 控制所有后台函数调用，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
