TCP Socket类
实现TCP协议的流式socket, TCP是面向连接的协议,提供可靠的数据传输、流量控制和拥塞控制。
主要功能:
- TCP socket创建和打开
- 连接建立(支持超时)
- 数据发送(普通、带超时、全部发送)
- 数据接收(普通、全部接收)
- SSL/TLS支持接口
使用示例:
string request = "GET / HTTP/1.1\r\nHost: example.com\r\n\r\n";
char buffer[4096];
if (received > 0) {
}
}
auto client_sock = server.accept();
NEFORCE_NODISCARD NEFORCE_CONSTEXPR20 view_type view() const noexcept

static NEFORCE_NODISCARD ip_address any(ports port=ports::undef, int family=AF_INET) noexcept
获取通配地址
static NEFORCE_NODISCARD optional< ip_address > parse(const string &host, ports port=ports{}) noexcept
从字符串解析IP地址
void bind(const ip_address &endpoint)
绑定socket到本地地址
void listen(int backlog)
开始监听连接(TCP)
void send_all(memory_view< const char > data)
发送所有数据
void open(int family=AF_INET)

bool connect(const ip_address &endpoint, milliseconds timeout, bool was_blocking=true)
连接到远程服务器
tcp_socket()=default
