1. 通信地址类封装测试

1.1 通过域名解析获取到相应的网址

目的：是否能通过域名解析获取到的对应的网址信息。
test_addr.cpp:

  1. static Logger::ptr g_logger = KIT_LOG_ROOT();
  3. void test()
  4. {
  5.     std::vector<Address::ptr> addrs;
  7.     bool val = Address::LookUp(addrs, "www.baidu.com");
  8.     if(!val)
  9.     {
  10.         KIT_LOG_ERROR(g_logger) << "Address::LookUp error!";
  11.         return;
  12.     }
  14.     //打印解析获取到的地址
  15.     for(size_t i = 0; i < addrs.size();++i)
  16.     {
  17.         KIT_LOG_INFO(g_logger) << i << "--" << addrs[i]->toString();
  18.     }
  19. }
  23. int main()
  24. {
  25.     KIT_LOG_INFO(g_logger) << "test begin";
  27.     test();
  29.     KIT_LOG_INFO(g_logger) << "test end";
  31.     return 0;
  32. }

疑惑：同样的地址出现了三组是为什么？

返回的协议类型protocol不相同。image.png

如果我们指定流式套接字就没有重复了

指定请求服务看是否能解析出对应的端口号

  • www.baidu.com:http``www.baidu.com:https www.baidu.com:ftp

1. 2 通过网卡获取相应的网址信息

目的：是否能通过网卡获取到对应的网址信息。

  • test_addr.cpp: ```cpp void test2() { std::multimap > mp;

    if(!Address::GetInertfaceAddresses(mp)) {

    1.   KIT_LOG_ERROR(g_logger) << "Address::GetInertfaceAddresses error";
    2.   return;

    }

    //将获取到的网址信息 逐一打印 for(auto &x : mp) {

    1.   KIT_LOG_INFO(g_logger) << x.first << "--" << x.second.first->toString() << "/" << x.second.second;

    }

}

int main() { KIT_LOG_INFO(g_logger) << “test begin”; test2(); KIT_LOG_INFO(g_logger) << “test end”;

  1. return 0;

}

  1. 在没有特别指定IPv4或IPv6的情况下都会打印出来<br />![image.png](https://cdn.nlark.com/yuque/0/2022/png/25460685/1645084077135-53ae4d36-19e5-471d-84bb-4824d78bd934.png#clientId=u06353b54-71b3-4&crop=0&crop=0&crop=1&crop=1&from=paste&height=126&id=u668a9e4d&margin=%5Bobject%20Object%5D&name=image.png&originHeight=126&originWidth=1052&originalType=binary&ratio=1&rotation=0&showTitle=false&size=27102&status=done&style=none&taskId=u1483a1a2-a160-47c9-8365-2a3504a4515&title=&width=1052)<br />![image.png](https://cdn.nlark.com/yuque/0/2022/png/25460685/1645084137272-cb8f2b43-8f35-47e3-9865-8d394253b2db.png#clientId=u06353b54-71b3-4&crop=0&crop=0&crop=1&crop=1&from=paste&height=319&id=uf19f8b63&margin=%5Bobject%20Object%5D&name=image.png&originHeight=319&originWidth=662&originalType=binary&ratio=1&rotation=0&showTitle=false&size=39057&status=done&style=none&taskId=u2c9d78d5-92fe-4394-88f8-1346cb0fbe6&title=&width=662)

  3. ## 1.3 通过网址解析IPv4相应信息
  4. 目的：IPv4相关功能是否正常，解析广播地址、网段、子网掩码等。
  6. - `test_addr.cpp`:
  7. ```cpp
  8. void test_ipv4()
  9. {
  10.     std::multimap<std::string, std::pair<Address::ptr, uint32_t> > mp;
  12.     if(!Address::GetInertfaceAddresses(mp))
  13.     {
  14.         KIT_LOG_ERROR(g_logger) << "Address::GetInertfaceAddresses error";
  15.         return;
  16.     }
  19.     for(auto &x : mp)
  20.     {
  22.         auto addr = std::dynamic_pointer_cast<IPAddress>(x.second.first);
  23.         if(addr->getAddr()->sa_family == AF_INET)
  24.             KIT_LOG_INFO(g_logger) << x.first << "--" << x.second.first->toString() << "/" << x.second.second << ", 广播地址:" << addr->broadcastAddress(x.second.second)->toString() << ", 子网地址:" << addr->subnetAddress(x.second.second)->toString();
  25.     }
  28. }
  31. int main()
  32. {
  33.     KIT_LOG_INFO(g_logger) << "test begin";
  34.     test_ipv4();
  36.     KIT_LOG_INFO(g_logger) << "test end";
  38.     return 0;
  39. }

2. Socket类封装测试

目的：观察封装的socket 相关一系列API是否正常。

  • test_socket.cpp：

域名转IP地址：Address::LookUpAnyIPAddress("www.baidu.com");
指定地址创建一个TCP连接：Socket::CreateTCP(addr);
连接指定地址的远端服务：sock->connect(addr)
发送数据：sock->send(buf, sizeof(buf));
接收数据：sock->recv(&temp[0], temp.size());

  1. static Logger::ptr g_logger = KIT_LOG_ROOT();
  3. void test_socket()
  4. {
  5.     //获取百度的通信地址
  6.     IPAddress::ptr addr = Address::LookUpAnyIPAddress("www.baidu.com");
  8.     if(addr)
  9.     {
  10.         KIT_LOG_INFO(g_logger) << "get address=" << addr->toString();
  11.     }
  12.     else
  13.     {
  14.         KIT_LOG_ERROR(g_logger) << "get addr fail";
  15.     }
  17.     Socket::ptr sock = Socket::CreateTCP(addr);
  18.     addr->setPort(80);
  19.     if(!sock->connect(addr))
  20.     {
  21.         KIT_LOG_ERROR(g_logger) << "connect:" << addr->toString() << " fail";
  22.     }
  23.     else
  24.     {
  25.         KIT_LOG_INFO(g_logger) << "connect:" << addr->toString() << " success";
  26.     }
  28.     //对百度发起一个HTTP请求
  29.     const char buf[] = 
  30.     "GET / HTTP/1.0\r\n"
  31.     "host: www.baidu.com\r\n"
  32.     "\r\n";
  33.     int ret = sock->send(buf, sizeof(buf));
  34.     if(ret <= 0)
  35.     {
  36.         KIT_LOG_ERROR(g_logger) << "send fail ret = " << ret;
  37.         return;
  38.     }
  40.     std::string temp;
  41.     temp.resize(10 * 1024);
  43.     ret = sock->recv(&temp[0], temp.size());
  44.     if(ret < 0)
  45.     {
  46.         KIT_LOG_ERROR(g_logger) << "recv fail ret = " << ret;
  47.         return;
  48.     }
  50.     std::cout << "size:" << ret << std::endl;
  51.     std::cout << "recv msg:\n" << temp << std::endl;
  52. }
  55. int main()
  56. {
  57.     KIT_LOG_DEBUG(g_logger) << "test begin";
  58.     IOManager iom;
  59.     iom.schedule(&test_socket);
  61.     KIT_LOG_DEBUG(g_logger) << "test end";
  63.     return 0;
  64. }
