thinkphp的一个小BUG

Jun 23, 2016 pm 02:11 PM

前两天发现自己网站莫名其妙的多了一下文件
原文地址:http://bbs.csdn.net/topics/390469279

今早观察了一下这些莫名其妙的HTML文件,终于找到问题所在!!!
原因:
如果开启静态缓存,在静态规则中带有参数,例如

//静态缓存	'HTML_CACHE_ON'=>true,	'HTML_CACHE_RULES'=> array(	'infor:search' => array('home/{:module}/{:action}/{key}'),	),
Copy after login


举例说明
{key}=test
Html/home/Infor/search/test.html
{key}=../boot
Html/home/Infor/boot.html
是的第二个静态文件HTML飞到了上级目录,所以服务器目录多了很多文件和文件夹。
这个应该算是thinkphp的一个小BUG,虽然不会对网站照成危害但是很烦人

解决的方法也很简单
就是静态规则不要直接用参数,推荐大家用MD5处理{$_SERVER.REQUEST_URI|md5}

机智的?丝

过来看看,静态缓存用的比较少。

这不是 thinkphp 的 bug
很自然的你要为你自己的行为负责

对于你示例的规则,若 key = ../boot
由 $rule  = preg_replace('/{(\w+)}/e',"\$_GET['\\1']",$rule);
可知,被解释成 home/MODULE_NAME/ACTION_NAME/../boot

TP 有什么理由要阻止你把静态文件放在上级目录中?

我觉得TP应该考虑一下{key}参数的过滤。

如果要过滤,也得是你给规则、写代码
至少类似 http://bbs.csdn.net/topics/390469279/..x 这样的url并不能构成攻击
你不能指望人家把什么都替你做了,毕竟他只是个开发工具。
如果是 dede 出现这种现象,才能说是 bug

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,

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.

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.

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.
