PHP 链接参数怎么加密(验证)
PHP 链接参数如何加密(验证)
我要是对显示出的一条记录进行删除，一般的做法就是把“删除”作为一个链接，链接的地址比如：http://121.121.121.121/del.php?id=$id，在del.php中接收id这个参数传来的值。
那么这样的话，我就可以直接在url里输入比如：http://121.121.121.121/del.php?id=43，对id是43的记录进行删除了，这样很不安全。
我看其他网站的相似的链接，参数中会有一个好几十个字母长的一个大的字符串，我想这个可能就是起到验证的作用吧。
那么验证部分该怎么写？或者说思路是什么？
谢谢。
------解决方案--------------------
这个删除肯定要有权限才能删除，不是随便一个人就可以删除的吧。。。
------解决方案--------------------
del.php页面要设置一个访问权限，比如session或cookie判断
------解决方案--------------------
也可以点删除之后用js以post的方式传参数，这样就不会暴露在url里了
------解决方案--------------------
。。。你删除页面至少也得判断个session["user"]，看看这个请求是不是登陆用户吧？
另外对于URL加密来说，你可以找PEAR里别人写的现成加密程序，再稍微改动一点点，成为你独自的加解密程序。

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.

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.

Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
