sae使用smarty模板的方法_php技巧
Smarty是非常流行的模板系统,它分离了业务和逻辑、执行速度快,在php网站中有广泛的运用。
不过在部署到sina app engine(sae)上时出现了问题,因为sae作为云计算平台式无法进行文件读写操作的,所以Smarty中输出的缓存文件就无法实现。
错误信息:“SAE_Fatal_error: Uncaught exception 'SmartyException' with message 'unable to write file ./web/templates_c/wrt4e95555280ef1' ”
SAE给出了解决方案就是使用Memcache。首先进入应用中的应用管理中,在服务管理中开启Memcache一个初始化,
然后修改Smarty的配置文件:
// For SAE 编译文件存放在memcache中
$smarty->compile_dir = 'saemc://smartytpl/';
$smarty->cache_dir = 'saemc://smartytpl/';
$smarty->compile_locking = false; // 防止调用touch,saemc会自动更新时间,不需要touch
上面三行是必须的。
这样Smarty模板就可以在SAE上运行了。

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,

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.

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.
