zpf 路由功能

2015-4-11 20:51:06

又搞了一天, 解决了一堆bug, 重新规划了类文件夹, 改善自动加载功能

最新的特性就是支持子域名路由了

因为整个框架还在完善当中, 而且里边有好多接口有我自己申请的第三方appkey 和 secretkey, 所以还不方便提供下载

但是路由功能完成以后,整体的框架也就快完工了, 再修修补补就行了

四年啦, 从零开始, 终于有模有样了....

比如: 

访问 www.zhangzhibin.com 是会跳转到网站首页的

访问 www.zhangzhibin.com/bbs 是会跳转到bbs论坛页面

但是我想在访问 love.zhangzhibin.com时也跳转到bbs论坛页面 (因为在大众点评留下的开发者信息是love.zhangzhibin.com)

此时可以在路由文件中设置一个对应关系就可以了(第8行):

public function setRoute()
    {
        $this->route_config = array(
            'subdomain' => array(),
            'uri' => array()
        );

        //================子域名路由
        $this->route_config['subdomain']['#love_(d)_([a-z])#'] = 'test/index/safe/$1/$2';
        $this->route_config['subdomain']['#love_(d)#'] = 'test/index/safe/$1';
        $this->route_config['subdomain']['#love#'] = 'bbs/index/index';


        //================ uri路由
        $this->route_config['uri']['#([a-z]+)_(d+).html#'] = 'test/index/testroute/$1/$2';
        $this->route_config['uri']['#map.html#'] = 'map/index/line';
    }

测试结果:

 2  3 
http://love_1.zhangzhibin.com/
Array
(
    [$1] => 1
)

http://love_1_a.zhangzhibin.com/
Array
(
    [$1] => 1
    [$2] => a
)

注意, 这里的路由项的键两边有两个'#'做为边界符是需要自己去写的, 如果担心冲突, 大家可以根据需要自己去设定边界符

整体的逻辑是这样的

先匹配子域名的路由, 然后匹配uri的路由(不匹配?后边的查询串)

将两步匹配到的参数合并起来, 因为uri在第二步匹配, 所以uri的匹配结果会覆盖掉子域名的路由结果

下边贴出代码: 

<?php
class Route
{
    public $subdomain = '';
    public $uri = '';

    public $ismatch = false;
    public $DomainMatchName = false;
    public $UriMatchName = false;
    public $MatchName = false;

    public $module = 'index';
    public $controller = 'index';
    public $action = 'index';

    public $args = array();

    public $error = '';
    
    public $route_config = array(
            'subdomain' => array(),
            'uri' => array()
        );    


    public function __construct($subdomain, $uri)
    {
        $this->subdomain = $subdomain;
        $this->uri = $uri;

        //设置路由配置信息
        $this->setRoute();

        //先检查子域名路由
        //如果子域名中只有英文字母就不再匹配
        if (!empty($this->route_config['subdomain']) || !ctype_alpha($this->subdomain)) {
            $this->DomainMatchName = $this->preg_parse($this->route_config['subdomain'], $this->subdomain);
        }

        //再检查uri路由
        //如果uri中不含有"/"才会走正则匹配
        if (!empty($this->route_config['uri']) && strpos($this->uri, '/') === false) {
            $this->UriMatchName = $this->preg_parse($this->route_config['uri'], $this->uri);
        } else {
            $this->arr_parse();
        }

        ($this->DomainMatchName || $this->UriMatchName) && ($this->ismatch = true);

        $this->MatchName = $this->UriMatchName ? $this->UriMatchName : $this->DomainMatchName;

        return $this;
    }

    public function setRoute()
    {
        //================子域名路由
        $this->route_config['subdomain']['#love_(d)_([a-z])#'] = 'test/index/safe/$1/$2';
        $this->route_config['subdomain']['#love_(d)#'] = 'test/index/safe/$1';
        $this->route_config['subdomain']['#love#'] = 'bbs/index/index';

        //================ uri路由
        $this->route_config['uri']['#svnsort#'] = 'index/index/svnsort';
        $this->route_config['uri']['#nicename_json#'] = 'index/index/nicenamejson';
        $this->route_config['uri']['#nicename#'] = 'index/index/nicename';
        $this->route_config['uri']['#test[^/]#'] = 'test/index/rtest'; //是下边路由的前缀, 加上就是全词匹配了
        $this->route_config['uri']['#test1#'] = 'test/index/rtest'; // 不会匹配test, 只会匹配test1

    }

    //正则匹配分析
    public function preg_parse($routeconfig, $subject)
    {
        $routename = false;
        foreach ($routeconfig as $pattern => $route) {
            $arrRoute = explode('/', $route);
            
            preg_match($pattern, $subject, $matches);

            if (empty($matches)) {
                continue;
            } else {
                $routename = $pattern;

                $arrMCA = array_slice($arrRoute, 0, 3);
                $arrArg = array_slice($arrRoute, 3);

                $this->module = $arrMCA[0];
                $this->controller = $arrMCA[1];
                $this->action = $arrMCA[2];

                $arrMatchArg = array();
                foreach ($matches as $key => $value) {
                    $arrMatchArg['$'.$key] = $value;
                }

                foreach ($arrArg as $value) {
                    $this->args[$value] = $arrMatchArg[$value];
                }

                break;
            }
        }

        return $routename;
    }

    //正则检查uri没有匹配上的情况下, 数组匹配分析
    public function arr_parse()
    {
        //获得module/controller/action
        $arrPathInfo = explode('/', $this->uri);//存放URL中以正斜线隔开的内容的数组
        
        !empty($arrPathInfo[0]) && ($this->module = $arrPathInfo[0]);
        !empty($arrPathInfo[1]) && ($this->controller = $arrPathInfo[1]);
        !empty($arrPathInfo[2]) && ($this->action = $arrPathInfo[2]);
        
        //存放除module/controller/action之外的参数
        // /a/1/b/2/c/3 ==> ?a=1&b=2&c=3
        // 当键和值不成对出现时,默认最后一个键的值为0
        // 参数中不要出现数字键,否则在合并post,get参数时会出错
        $intPathInfo = count($arrPathInfo);
        if ($intPathInfo > 3) {
            $arrPath = array_slice($arrPathInfo, 3);
            $intArgNum = count($arrPath);
            if ($intArgNum % 2 != 0) {
                $arrPath[] = 0;
            }
            $intArgNum = count($arrPath);

            for ($i=0; $i<$intArgNum; $i=$i+2) {
                $this->args[$arrPath[$i]] = $arrPath[$i+1];
            }
        }
    }
}

 当然你也可以写自己的路由类, 只需要返回给框架所需要的数据就行啦~

    //可以自己实现路由类, 只要要返回 module, controller, action, 以及匹配到的参数就行了
    //返回是否匹配了路由, 匹配路由的名字, 路由指向的module,controller,action, 路由错误信息,方便调试
    public function route()
    {
        $this->route = new Route($this->subdomain, $this->document_uri);
        
        $this->isRouteMatch = $this->route->ismatch;
        $this->RouteMatchName = $this->route->MatchName;

        $this->module = $this->route->module;
        $this->controller = $this->route->controller;
        $this->action = $this->route->action;

        $this->setData();
    }
