HomeBackend DevelopmentPHP Tutorial请教Discuz!X开发者:如何挂钩代码,使得在用户上传头像的时候,执行特定的判断和操作动作?

论坛管理中碰到的问题。最近碰到了大批有着如此特征的发帖机:

  • 能够绕过注册问题认证、见习期认证、头像认证,我估计email认证也能绕
  • 用户名一般很随机
  • 发送广告帖骗取大量链接
  • 头像是非常统一的“晕头”图标 (445 Bytes, sha1 checksum=53624f5183539b2f02a799a25136856a84f8c810)

造成的效果如下:

请教Discuz!X开发者:如何挂钩代码,使得在用户上传头像的时候,执行特定的判断和操作动作?

我希望能够在上传头像时,识别这个“晕头”图像,识别到了立刻锁定用户,来挡一下这类的发帖机。

Discuz的文档不完善,网上搜的也没有好的方案(注:Discuz禁止fork再传播,所以是冒牌的“开源”,社区支持不积极情有可原)……因此提问请教两个问题:

  • 如果想在上传头像这一步挂代码,挂在哪里?
  • 用什么函数通知Discuz锁定用户?

我觉得封头像这个事情可以先不要想了……

可以考虑封IP,关键字(很有效)。

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
