在flask中使用render_template能够防御XSS漏洞,但在使用safe过滤器的情况下还是会导致XSS returnrender_template('xss.html', name=name) 前端代码为 Hello {{ name|safe }}! XXE XML外部实体注入。当允许引用外部实体时,通过构造恶意内容,就可能导致任意文件读取、系统命令执行、内网端口探测、攻击内网网站等危害 在...
首先关于在python中单线程,多线程,多进程对cpu的利用率实测如下: 单线程,多线程,多进程测试代码使用死循环。 1)单线程: 2)多线程: 3)多进程: 查看cpu使用效率: 开始观察分别执行时候cpu的使用效率: 1)单线程执行的时候: 2)多线程执行的时候: 3)多进程执行的时候: 总结: 1)单进程单线程时,对于双核CPU的...

threads from executing Python bytecodes at once. The GIL prevents race conditions and ensures thread safety. A nice explanation ofhow the Python GIL helps in these areas can be found here. In short, this mutex is necessary mainly because CPython's memory management is not thread-safe.[1] ...
