php兑现url伪静态化
php实现url伪静态化
url的静态化,我一般借助于apache,nginx,htaccess等,很少用php来实现url的静态化,用php来实现静态化比较麻烦,所以就个人而言是不推荐使用php来实现url静态化
一,url的静态化实现的原理
1,通过程序来把动态的url转换成静态的url,转换方法最好是统一的接口。把静态的url放到html中,这样我们通过页面看到的就是静态的url。
2,apache或者其他,加载rewrite模块,添加重写规则。这样当我们点页面中的静态url时,就可以转向正确的url了。虽然执行的还是php文件,但是浏览器的地址栏中显示出来的,还是静态的url。
如果用php来实现url静态化,也要保持地址栏里面也要静态的url,这个比较麻烦的,下面就这个来举个简单的例子。
二,把动态url转换成静态url

到这儿如果直接点击的话,肯定会报404错误的,因为根不可能找到tank这个目录的。难点也在这儿,所以我们要把找不到的目录和文件指定一个php文件。这个要利用到apache,nginx,或者htaccess等。
三,指定一个统一入口

不管你是以.htaccess的方式来实现,还是写在apache等的配置文件中,都是可以的。上面三句话是什么意思呢,如果找不到目录转到index.php文件,如果找不到文件,也转到index.php。
这样做了,当我们访问http://localhost/test3/test.php/User/check/tank时候,就会转到index.php来,既然知道到那个php文件了,那就好办了。
以下内容都是以http://localhost/test3/test.php/User/check/tank这种重写的方式来操作的,其他方式也都差不多。
四,index.php文件,URL映射解析类http://hudeyong926.iteye.com/admin/blogs/1113971

?五,test.php文件

到这儿,当我们访问http://localhost/test3/test.php/User/check/tank这个网址的时候,
结果如下:我的名子叫tank,并且地址栏还仍然保持着静态。
到这儿通过php,我们完成了一个简单的url的重写过程。其实还是借助了.htaccess,或者apache等,但是重写的规则没有在.htaccess,或者apache中。如果完全用php来实现url的静态化,个人感觉,不可能。

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,
