关于U 方法
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);
(
[path] => verify
)

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,

Article discusses late static binding (LSB) in PHP, introduced in PHP 5.3, allowing runtime resolution of static method calls for more flexible inheritance.Main issue: LSB vs. traditional polymorphism; LSB's practical applications and potential perfo

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.

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.

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.
