关于U 方法

Jun 23, 2016 pm 01:35 PM

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

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

Explain late static binding in PHP (static::). Explain late static binding in PHP (static::). Apr 03, 2025 am 12:04 AM

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
