先说说提这个问题的由头:看到别人在thinkphp中用U方法时,这样用  U('verify')
其中参数verify是自定义的一个控制器里的方法
那么问题来了这种形式的调用为啥能有效呢,下面是U方法的写法,从中没有看出哪里可以这样使用呢?

function U($url,$vars='',$suffix=true,$redirect=false,$domain=false) {    // 解析URL    $info =  parse_url($url);    $url   =  !empty($info['path'])?$info['path']:ACTION_NAME;    // 解析子域名    if($domain===true){        $domain = $_SERVER['HTTP_HOST'];        if(C('APP_SUB_DOMAIN_DEPLOY') ) { // 开启子域名部署            $domain = $domain=='localhost'?'localhost':'www'.strstr($_SERVER['HTTP_HOST'],'.');            // '子域名'=>array('项目[/分组]');            foreach (C('APP_SUB_DOMAIN_RULES') as $key => $rule) {                if(false === strpos($key,'*') && 0=== strpos($url,$rule[0])) {                    $domain = $key.strstr($domain,'.'); // 生成对应子域名                    $url   =  substr_replace($url,'',0,strlen($rule[0]));                    break;                }            }        }    }    // 解析参数    if(is_string($vars)) { // aaa=1&bbb=2 转换成数组        parse_str($vars,$vars);    }elseif(!is_array($vars)){        $vars = array();    }    if(isset($info['query'])) { // 解析地址里面参数 合并到vars        parse_str($info['query'],$params);        $vars = array_merge($params,$vars);    }    // URL组装    $depr = C('URL_PATHINFO_DEPR');    if($url) {        if(0=== strpos($url,'/')) {// 定义路由            $route   =  true;            $url   =  substr($url,1);            if('/' != $depr) {                $url   =  str_replace('/',$depr,$url);            }        }else{            if('/' != $depr) { // 安全替换                $url   =  str_replace('/',$depr,$url);            }            // 解析分组、模块和操作            $url   =  trim($url,$depr);            $path = explode($depr,$url);            $var  =  array();            $var[C('VAR_ACTION')] = !empty($path)?array_pop($path):ACTION_NAME;            $var[C('VAR_MODULE')] = !empty($path)?array_pop($path):MODULE_NAME;            if(C('URL_CASE_INSENSITIVE')) {                $var[C('VAR_MODULE')] =  parse_name($var[C('VAR_MODULE')]);            }            if(C('APP_GROUP_LIST')) {                if(!empty($path)) {                    $group   =  array_pop($path);                    $var[C('VAR_GROUP')]  =   $group;                }else{                    if(GROUP_NAME != C('DEFAULT_GROUP')) {                        $var[C('VAR_GROUP')]  =   GROUP_NAME;                    }                }            }        }    }    if(C('URL_MODEL') == 0) { // 普通模式URL转换        $url   =  __APP__.'?'.http_build_query($var);        if(!empty($vars)) {            $vars = http_build_query($vars);            $url   .= '&'.$vars;        }    }else{ // PATHINFO模式或者兼容URL模式        if(isset($route)) {            $url   =  __APP__.'/'.$url;        }else{            $url   =  __APP__.'/'.implode($depr,array_reverse($var));        }        if(!empty($vars)) { // 添加参数            $vars = http_build_query($vars);            $url .= $depr.str_replace(array('=','&'),$depr,$vars);        }        if($suffix) {            $suffix   =  $suffix===true?C('URL_HTML_SUFFIX'):$suffix;            if($suffix) {                $url  .=  '.'.ltrim($suffix,'.');            }        }    }    if($domain) {        $url   =  'http://'.$domain.$url;    }    if($redirect) // 直接跳转URL        redirect($url);    else        return $url;}// URL重定向

回复讨论(解决方案)

$url = 'verify';$info = parse_url($url);
Copy after login
Array
(
    [path] => verify
)
你跟踪一下就知道了
