php开发中的页面跳转方法总结_PHP
页面跳转可能是由于用户单击链接、按钮等触发的,也可能是系统自动产生的。页面自动跳转在WEB开发中经常用到,而且根据需求可以采用不同的跳转方式,比如提示操作信息后延时跳转等, 本文总结了WEB开发中常见的几种页面跳转方法。
PHP header()函数跳转
PHP的header()函数非常强大,其中在页面url跳转方面也调用简单,使用header()直接跳转到指定url页面,这时页面跳转是302重定向:
$url = "http://www.bitsCN.com/"; header( "Location: $url" );
我们有可能会遇到特殊的跳转时,比如网站改版有个页面地址要做301重定向,当然你可以通过web配置rewrite来实现,但现在我要告诉大家,可以使用php的header()函数做301跳转,代码如下:
//301跳转 header( "HTTP/1.1 301 Moved Permanently" ); header( "Location: $url" );
Meta设置跳转
html中的meta信息里可以直接设置跳转,可以设置跳转延迟时间和跳转url,经常应用,比如支付完了告诉用户支付成功并跳转到订单页面,代码非常简单,就在
中加上一句:
<meta http-equiv="refresh" content="5;url=http://www.bitsCN.com">
以上代码表示在5秒钟后页面会自动跳转到http://www.bitsCN.com。
Javascript跳转
Javascript跳转也非常简单,直接一句话:
<script> window.location.href="http://www.bitsCN.com"; </script>
注意,上面这段代码直接跳转后,在目标页面地址中是获取不到来路(referer,也叫来源)的,在实际项目中,遇到有客户要求跳转要带来路(即目标网页可以获取到页面从哪里跳转来的),这时,我们可以用javascript模拟一次点击,然后跳转就满足了客户的需求。
<script> //有来路 var aa = document.createElement("a"); aa.setAttribute("href","http://www.bitsCN.com"); var bodys=document.getElementsByTagName("body")[0]; bodys.appendChild(aa); aa.click(); </script>
当然,实际开发中我们可以把后面两种方式整合到PHP中去,便于适用各种跳转需求。

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,
