场景解释

step1: SUBSCRIBE 客户端想要订阅某个分机的状态
step2: 200 Ok 服务端接受了这个订阅消息
step3: NOTIFY 服务端向客户端返回他的订阅目标的状态
step4: 200 Ok 客户端返回表示接受

定义配置文件

#!/bin/bash
# conf.sh

edge_address='192.168.40.88:18627'
my_ext='8003'
my_domain='ss.cc'
my_monitor='8004'

定义状态码处理函数

用来处理来自sipp的返回的状态码

#!/bin/bash
# util.sh
log_error () {
    case $1 in
    0) echo INFO: test success 
    ;;
    1) echo ERROR: At least one call failed
    ;;
    97) echo ERROR: Exit on internal command. Calls may have been processed
    ;;
    99) echo ERROR: Normal exit without calls processed
    ;;
    -1) echo ERROR: Fatal error
    ;;
    -2) echo ERROR: Fatal error binding a socket
    ;;
    *)  echo ERROR: Unknow exit code $0
    ;;
    esac
}

启动文件

  • -key 用来定义变量，在场景文件中存在三个变量
    • [my_ext] 当前分机号
    • [my_domain] 当前分机域名
    • [my_monitor] 当前分机想要监控的分机号
  • -recv_timeout 表示设置接受消息的超时时间为1000毫秒
  • -timeout 设置整个运行过程的超时时间
  • -sf 指定场景文件
  • -m  设置最大处理的呼叫数
  • -l  设置并发呼叫数量
  • -r 设置呼叫速度
#!/bin/bash
# test.sh

source ../util.sh
source ./conf.sh

rm *.log

sipp -trace_logs $edge_address \
        -key my_ext $my_ext \
        -key my_domain $my_domain \
        -key my_monitor $my_monitor \
        -recv_timeout 1000 \
        -timeout 2 \
        -sf ./subscibe.xml -m 1 -l 1 -r 1;

log_error $?

执行测试：

chmod +x test.sh
./test.sh
