实例脚本
在eXosip中,当用户第一次发送注册请求后,eXosip会产生EXOSIP_REGISTRATION_FAILURE事件,注意这并不一定是注册失败,用户需要根据event->response->status_code 来判断具体的状态,如果是401状态,则是服务器需要用户再次发送带认证信息的注册请求;如果是其他值,则认为注册失败,比如无法连接服务器等。
对于EXOSIP_REGISTRATION_FAILURE事件,有两种处理方式:
1、自动处理。
在eXosip事件处理循环中调用eXosip_automatic_action()函数,该函数会自动帮助用户处理401/407状态,用户并不再需要手动发送带认证信息的注册请求,只需要在第一次注册时就添加好认证信息即可;
2、手动处理,需要在EXOSIP_REGISTRATION_FAILURE事件中增加以下代码:
/** SIP Registration Agent -- by ww@styx.org* * This program is Free Software, released under the GNU General* Public License v2.0 http://www.gnu.org/licenses/gpl** This program will register to a SIP proxy using the contact* supplied on the command line. This is useful if, for some * reason your SIP client cannot register to the proxy itself.* For example, if your SIP client registers to Proxy A, but* you want to be able to recieve calls that arrive at Proxy B,* you can use this program to register the client's contact* information to Proxy B.** This program requires the eXosip library. To compile,* assuming your eXosip installation is in /usr/local,* use something like:** gcc -O2 -I/usr/local/include -L/usr/local/lib sipreg.c \* -o sipreg \* -leXosip2 -losip2 -losipparser2 -lpthread** It should compile and run on any POSIX compliant system* that supports pthreads.**/#if defined(__arc__)
