C++11解析url

之前使用boost解析字符串，因为编译跨平台的boost比较麻烦，现在尝试使用C++11，效果一样，以下是一个解析url的简单demo

#include <iostream>

#include <regex>int url2domain(const std::string &url, std::string &domain, unsigned &port){int ret = -1;//使用迭代器拆分字符串 http://www.cppprog.com/2009/0112/48.htmlstd::regex reg_domain_port("/");  //按/符拆分字符串std::cregex_token_iterator itrBegin(url.c_str(), url.c_str() + url.size(), reg_domain_port, -1);std::cregex_token_iterator itrEnd;int i = 0;std::string domain_port;for (std::cregex_token_iterator itr = itrBegin; itr != itrEnd; ++itr){i++;if (i == 3){domain_port = *itr;}}if (domain_port.size() == 0){domain_port = url;}//考虑带端口的情况std::regex reg_port(":");std::cregex_token_iterator itrBegin2(domain_port.c_str(), domain_port.c_str() + domain_port.size(), reg_port, -1);std::cregex_token_iterator itrEnd2;int j = 0;for (std::cregex_token_iterator itr = itrBegin2; itr != itrEnd2; ++itr){j++;if (j == 1){domain = *itr;}if (j == 2){port = std::stold(*itr);//itoa(port,*itr,5);;}}if (domain.size() == 0){domain = domain_port;}return ret;}std::string urls[] = {"hrbcyyzy-video.guisen.com.cn","hrbcyyzy-video.guisen.com.cn:80","http:://hrbcyyzy-video.guisen.com.cn","http:://hrbcyyzy-video.guisen.com.cn:80","http:://hrbcyyzy-video.guisen.com.cn/222","http:://hrbcyyzy-video.guisen.com.cn:80/222"};int main(){int ret = -1;std::string domain;unsigned int port = 0;for (int i = 0; i < 6; i++){url2domain(urls[i], domain, port);}return 0;}
