windows下UDP单播、广播播和组播实例

首先需要下载Boost库,并在VS中配置Boost的路径。
接下来,可以按照以下步骤实现UDP通信:
1. 引入头文件和命名空间
```cpp
#include <iostream>
#include <boost/asio.hpp>
using namespace boost::asio;
```
2. 创建io_service对象
```cpp
io_service service;
```
3. 创建UDP socket
```cpp
ip::udp::socket socket(service);
```
4. 绑定端口号
```cpp
ip::udp::endpoint endpoint(ip::udp::v4(), port);
socket.open(endpoint.protocol());
socket.bind(endpoint);
```
其中`port`为要绑定的端口号。
5. 接收数据
```cpp
char buffer[1024];
ip::udp::endpoint sender_endpoint;
socket.receive_from(buffer, 1024, sender_endpoint);
std::cout << "Received data: " << buffer << std::endl;
```
`receive_from`函数会阻塞等待接收数据,并将发送方的IP和端口信息存储在`sender_endpoint`中。
6. 发送数据
```cpp
char data[] = "Hello, world!";
ip::udp::endpoint receiver_endpoint(ip::address::from_string("127.0.0.1"), port);
socket.send_to(buffer(data), receiver_endpoint);
```
其中`receiver_endpoint`为要发送到的IP和端口信息。
完整代码示例:
```cpp
#include <iostream>
#include <boost/asio.hpp>
using namespace boost::asio;
int main()
{
io_service service;
ip::udp::socket socket(service);
int port = 12345;
ip::udp::endpoint endpoint(ip::udp::v4(), port);
socket.open(endpoint.protocol());
socket.bind(endpoint);
char buffer[1024];
ip::udp::endpoint sender_endpoint;
socket.receive_from(buffer, 1024, sender_endpoint);
std::cout << "Received data: " << buffer << std::endl;
char data[] = "Hello, world!";
ip::udp::endpoint receiver_endpoint(ip::address::from_string("127.0.0.1"), port);
socket.send_to(buffer(data), receiver_endpoint);
return 0;
}
```
