It’s been a long time since I posted code here

It is divided into 3 parts to complete the ajax calling logic of php. The following is the general structure

Part one: ajax request: mainly the action parameter, LoginController is the class name of php, login is the function name in the LoginController class

$('#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>

Copy after login

Part 2: Controller.php, this file is to call controllers of other specific functional classes and plays a pivotal role, mainly through reflection

<?<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>$exc</span><span>) {
        </span><span>echo</span> <span>$exc</span>-><span>getTraceAsString();
    }
}
</span>?>

The third part: LoginController.php, this file is a specific functional class

<?<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>?>
