[HTTP]_[C/C++]_[获取URL里的域名主体]

场景:

1.有时候需要获取域名主体来做一些记录操作或公司名称记录,比如域名baidu.com域名的主体是baidu.

2.在blog下载工具里博客下载备份导出工具需要根据不同的域名主体来调用相应的下载脚本，域名主体同时也是包名。

#include <iostream>#include <stdlib.h>#include <string.h>#include <string>#include "domain.h"#include "assert.h"using namespace std;char* GetDomainTopPart(const char* url1){cout << url1 << endl;//1.获取域名char* url = strdup(url1);const char* http_str = "http://";char slash = '/';char dot = '.';char* http_pr = strstr(url,http_str);char* start = url;if (http_pr == url){start = url+strlen(http_str);}char* slash_pr = strchr(start,slash);*slash_pr = 0;//1.从第2部分开始查找char* domain_top = NULL;char* first_dot = strrchr(start,dot);*first_dot = 0;char* second_dot = strrchr(start,dot);if(second_dot){*first_dot = dot;char* second_part = strstr(gDomainPart,second_dot);if (second_part){*second_dot = 0;char* third_dot = strrchr(start,dot);if (third_dot){domain_top = strdup(third_dot+1);}else{domain_top = strdup(start);}}else{*first_dot = 0;domain_top = strdup(second_dot+1);}}else{*first_dot = 0;domain_top = strdup(start);}free(url);return domain_top;}int main(int argc, char const *argv[]){cout << gDomainPart << endl;cout << argv[0] << endl;char* domain_top = GetDomainTopPart("http://blog.csdn.net/infoworld/1.html");assert(!strcmp(domain_top,"csdn"));free(domain_top);domain_top = GetDomainTopPart("blog.csdn.net/infoworld/1.html");assert(!strcmp(domain_top,"csdn"));free(domain_top);domain_top = GetDomainTopPart("http://tomcat-oracle.iteye.com/blog/2020634");assert(!strcmp(domain_top,"iteye"));free(domain_top);domain_top = GetDomainTopPart("http://www.blogjava.net/paulwong/archive/2014/02/23/410200.html");assert(!strcmp(domain_top,"blogjava"));free(domain_top);domain_top = GetDomainTopPart("http://blogjava.net/paulwong/archive/2014/02/23/410200.html");assert(!strcmp(domain_top,"blogjava"));free(domain_top);domain_top = GetDomainTopPart("http://test.com.cn/paulwong/archive/2014/02/23/410200.html");assert(!strcmp(domain_top,"test"));free(domain_top);domain_top = GetDomainTopPart("http://www.test.com.cn/paulwong/archive/2014/02/23/410200.html");assert(!strcmp(domain_top,"test"));free(domain_top);return 0;}

域名后缀头文件 domain.h:

static const char* gDomainPart = "" ";.com" ";.net" ";.org" ";.hk" ";.cn" ";.com.cn" ";.net.cn" ";.org.cn" ";.gov.cn" ";.biz" ";.info" ";.cc" ";.tv" ";.mobi" ";.name" ";.asia" ";.tw" ";.sh" ";.ac" ";.io" ";.tm" ";.travel" ";.ws" ";.us" ";.sc" ";.mn" ";.ag" ";.vc" ";.la" ";.bz" ";.in" ";.cm" ";.co" ";.tel" ";.me" ";.pro" ";.com.hk" ";.com.tw" ";.pw;";

输出:
