exosip库服务器支持ipv4和ipv6客户端连接代码-DPDK中文网

以下是一个简单的eXosip库服务器支持IPv4和IPv6客户端连接的代码示例：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <netinet/in.h>
#include <arpa/inet.h>

#include <eXosip2/eXosip.h>

int main(int argc, char **argv)
{
    int status = -1;
    eXosip_t *ctx = NULL;

    /* 初始化 eXosip 库 */
    ctx = eXosip_malloc();
    status = eXosip_init(ctx);
    if (status != 0) {
        fprintf(stderr, "Error initializing eXosip.\n");
        exit(EXIT_FAILURE);
    }

    /* 设置 SIP URI 地址 */
    osip_uri_t *uri = NULL;
    const char *sip_uri = "sip:example.com";
    uri = eXosip_parse_url(sip_uri);
    if (!uri) {
        fprintf(stderr, "Error parsing SIP URI: %s\n", sip_uri);
        exit(EXIT_FAILURE);
    }

    /* 创建 IPv4 和 IPv6 监听套接字 */
    int sock_v4, sock_v6;
    struct sockaddr_in addr_v4;
    struct sockaddr_in6 addr_v6;

     // 创建 IPv4 套接字
     memset(&addr_v4, 0x00, sizeof(addr_v4));
     addr_v4.sin_family = AF_INET;
     addr_v4.sin_addr.s_addr = htonl(INADDR_ANY); 
     addr_v4.sin_port=htons(5060); 

     sock_v4=socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP); 
     bind(sock_v4, (struct sockaddr*)&addr_v4, sizeof(addr_v4)); 

     // 创建 IPv6 套接字
     memset(&addr_v6, 0x00, sizeof(addr_v6));
     addr_v6.sin6_family = AF_INET6;
     addr_v6.sin6_addr = in6addr_any; 
     addr_v6.sin6_port=htons(5060); 

     sock_v6=socket(AF_INET6, SOCK_DGRAM, IPPROTO_UDP);
     bind(sock_v6, (struct sockaddr*)&addr_v6, sizeof(addr_v6)); 

    /* 启动 eXosip 库服务器 */
    status = eXosip_listen_addr(ctx, IPPROTO_UDP,
                                NULL, /* IPv4 监听地址 */
                                5060,
                                AF_INET,
                                NULL, /* IPv4 备用监听地址 */
                                NULL, /* IPv4 额外监听参数 */
                                NULL, /* IPv4 额外监听选项 */
                                -1,
                                IPPROTO_UDP,
                                NULL, /* IPv6 监听地址 */
                                5060,
                                AF_INET6,
                                NULL, /* IPv6 备用监听地址 */
                                NULL  /* IPv6 额外监听选项 */);
    if (status != 0) {
        fprintf(stderr, "Error starting eXosip server.\n");
        exit(EXIT_FAILURE);
    }

    printf("eXosip server started successfully.\n");

    while (1) {
        int nfds = eXosip_fd_wait(ctx, 1000);
        if (nfds < 0) {
            fprintf(stderr,"Error waiting for events\n");
            break;
        }
        status = eXosip_event_wait(ctx, 1);

        if (status >= 0) {
            printf("SIP event received.\n");
            // TODO: 处理 SIP 请求和响应
        } else {
            printf("No SIP event received.\n");
        }
    }

    /* 清理 eXosip 库 */
    eXosip_quit(ctx);
    eXosip_free(ctx);
}

上述代码中，我们创建了一个eXosip库服务器，并启用了IPv4和IPv6监听套接字。在等待SIP事件的循环中，我们可以添加代码以处理具体的SIP请求和响应。
