这是一个函数，只要调用这个函数，就可以获取网页的内容

调用方法

int main(){	//CString strResponse = HttpRequest("translate.google.com",80,"/translate_t?langpair=en|zh-CN","POST","hl=zh-CN&ie=UTF-8&text=this is me&langpair=en|zh-CN",strlen("hl=zh-CN&ie=UTF-8&text=this is me&langpair=en|zh-CN"));	std::string strResponse = HttpRequest("www.qsxck.com", 80, "/", "GET", NULL, 0);		//cout << strResponse.c_str();		FILE * fp;	errno_t t =  fopen_s(&fp,"D:\\old.html", "w");		fwrite(strResponse.c_str(),1, strResponse.length(), fp);	fclose(fp);	getchar();    return 0;}
