及其相关 对字符串内容进行匹配的最常见手段就是使用正则表达式。可惜在传统 C++ 中正则表达式一直没 有得到语言层面的支持，没有纳入标准库，而 C++ 作为一门高性能语言，在后台服务的开发中，对 URL 资源链接进行判断时，使用正则表达式也是工业界最为成熟的普遍做法。 一般的解决方案就是使用 boost 的正则表达式库。而 C++11 正式将正则表达式的的处理方法纳入 标准库的行列，从语言级上提供了标准的支持，不再依赖第三方。 总结 本节简单介绍了正则表达式本身，然后根据使用正则表达式的主要需求，通过一个实际的例子介绍 了正则表达式库的使用。 习题 1. 在 Web 服务器开发中，我们通常希望服务某些满足某个条件的路由。正则表达式便是完成这一目 标的工具之一。 给定如下请求结构： 60 习题 第 6 章正则表达式 struct Request { // request method, POST, GET; parse_request(std::istream& stream) const { // TODO } } 请实现成员函数 start() 与 parse_request。使得服务器模板使用者可以如下指定路由： template void start_server(SERVER_TYPE &server) { // process GET request

勉强有点概念，但是到了第三章，感觉好象世界末日了。MFC 六大技术的仿真...好象很 难懂，读起来非常吃力 是不是有其它书讲得比较简单的？我不是计算机科系学生，只是 对计算机程序设计有兴趣，一路由basic -> FORTRAN -> C -> C++ 走来... szu.bbs@bbs.es.ncku.edu.tw：是的，第三章也许是世界末日，当初我看的时候也是跳过不 看，不然就是看完frame1
