当使用exosip2库时,可以通过以下示例代码来支持IPv4和IPv6客户端注册:
#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[])
{
eXosip_t *ctx;
int err;
// 初始化eXoSIP库
ctx = eXosip_malloc();
if (ctx == NULL) {
printf("eXoSIP initialization failed!\n");
return -1;
}
// 启动eXoSIP库
err = eXosip_init(ctx);
if (err != OSIP_SUCCESS) {
printf("Unable to initialize the eXoSIP library!\n");
return -1;
}
// 注册IPv4客户端
osip_uri_t *local_uri_ipv4;
const char *ipv4_addr = "192.168.0.1";
local_uri_ipv4 = eXosip_build_uri(ipv4_addr, NULL, NULL);
int reg_id_ipv4 = eXosip_register_uac(local_uri_ipv4, NULL, NULL, 1800, ®_call_id);
if(reg_id_ipv4 <= 0){
printf("Registeration failed for IPv4 client\n");
}
osip_uri_free(local_uri_ipv4);
// 注册IPv6客户端
osip_uri_t *local_uri_ipv6;
const char *ipv6_addr = "2001:db8::7";
local_uri_ipv6 = eXosip_build_transport_param(uri_ip_v6, ipv6_addr);
int reg_id_ipv6 = eXosip_register_uac(local_uri_ipv6, NULL, NULL, 1800, ®_call_id);
if(reg_id_ipv6 <= 0){
printf("Registeration failed for IPv6 client\n");
}
osip_uri_free(local_uri_ipv6);
// 等待接收SIP消息
while (1) {
eXosip_event_t *ev;
ev = eXosip_event_wait(ctx, 0, 100);
if (ev == NULL) {
continue;
}
switch (ev->type) {
case EXOSIP_REGISTRATION_FAILURE:
printf("Registration failure!\n");
break;
case EXOSIP_REGISTRATION_SUCCESS:
printf("Registration success!\n");
break;
// 处理其他事件
default:
break;
}
}
// 清理eXoSIP库
eXosip_quit(ctx);
eXosip_free(ctx);
return 0;
}
在上述示例代码中,首先通过eXosip_build_uri()
函数创建本地IPv4地址和端口号的URI对象,并通过eXosip_register_uac()
函数向服务器注册客户端。类似地,在创建本地IPv6地址和端口号的URI对象之后,同样可以调用eXosip_register_uac()
函数来注册IPv6客户端。
需要注意的是,在此示例代码中,我们使用了基于UDP传输协议的SIP消息传输方式。如果您需要使用TCP或TLS,请将对应参数传递给eXosip_register_uac()
函数即可。
