获取本机地址信息,遇到小问题...有待解决
程序代码:
1 #include "../common/InitSock.h" 2 #include <stdio.h> 3 CInitSock initSock; 4 void main() 5 { 6 char szHost[256]; 7 ::gethostname(szHost,256); 8 hostent *pHost = ::gethostbyname(szHost); 9 in_addr addr; 10 for(int i =0;;i++) 11 { 12 char *p = pHost->h_addr_list[i]; 13 if(p == NULL) 14 break; 15 memcpy(&addr.S_un.S_addr, p, pHost->h_length); 16 char *szIp = ::inet_ntoa(addr); 17 printf("本地IP地址:%s \n",szIp); 18 } 19 }
第一次编译说 找不到 ../common/InitSock.h
然后百度说,自己弄个头文件就行:
1 #include <winsock2.h> 2 #pragma comment(lib, "WS2_32 ") 3 #pragma comment(lib, "ws2.lib ") // 链接到WS2_32.lib 4 class CInitSock 5 { 6 public: 7 CInitSock(BYTE minorVer = 2, BYTE majorVer = 2) 8 { 9 // 初始化WS2_32.dll 10 WSADATA wsaData; 11 WORD sockVersion = MAKEWORD(minorVer, majorVer); 12 if(::WSAStartup(sockVersion, &wsaData) != 0) 13 { 14 exit(0); 15 } 16 } 17 18 ~CInitSock() 19 { 20 ::WSACleanup(); 21 } 22 };
然后保存成:initsock.h 但这个方法不好使:
然后继续编译,说是缺少win32.lib...很是奇怪
