在使用Asterisk通信系统时，了解活动呼叫数量对于监控和管理呼叫流量非常重要。而通过Asterisk Manager接口可以获取到各种事件信息，包括呼叫数量。本文将向您介绍如何使用Asterisk Manager接口来获取活动呼叫数量的方法和步骤。无论您是Asterisk的新手还是有经验的用户，本文都会为您提供详细的指导。让我们一起来看看吧！
我已经连接到星号，并设法从事件 peerstatus 中获取活动和非活动对等点的数量，但现在我需要获取活动呼叫和通道的数量并显示它们。我尝试过寻找 channelstatedesc=up 的方法，但它不起作用。即使我放置日志，我也看不到该事件被发现。我该如何修复它（也许通过事件 coreshowchannelscomplete？）提前致谢
//server.go
package server
import (
"bufio"
"fmt"
"net"
"strings"
"data"
)
func connecttoami(address, username, password string) error {
conn, err := net.dial("tcp", address)
if err != nil {
return err
}
defer conn.close()
fmt.fprintf(conn, "action: login\r\nusername: %s\r\nsecret: %s\r\n\r\n", username, password)
peerstatus := &data.peerstatus{}
callstatus := &data.callstatus{}
scanner := bufio.newscanner(conn)
for scanner.scan() {
line := scanner.text()
fmt.println(line)
if strings.hasprefix(line, "peerstatus") {
data.getpeerstatus(line, peerstatus)
fmt.println("active peers:", peerstatus.active)
fmt.println("inactive peers:", peerstatus.inactive)
} else if strings.hasprefix(line, "coreshowchannel") {
data.getchannelstatus(line, callstatus)
fmt.println("active peers:", peerstatus.active)
fmt.println("inactive peers:", peerstatus.inactive)
}
}
if err := scanner.err(); err != nil {
return err
}
return nil
}//calls.go
package data
import (
"encoding/json"
"fmt"
"strings"
)
type CallStatus struct {
ActiveCalls int `json:"active_calls"`
ActiveChannels int `json:"active_channels"`
}
func (cs *CallStatus) UpdateCallStatus(state string) {
fmt.Println("UpdateCallStatus function", state)
switch state {
case "Up":
cs.ActiveCalls++
cs.ActiveChannels = cs.ActiveCalls * 2
case "Down":
cs.ActiveCalls--
cs.ActiveChannels=cs.ActiveChannels-2
default:
}
}
func GetChannelStatus(event string, callStatus *CallStatus) {
fmt.Println("GetChannelStatus function", event)
for _, line := range strings.Split(event, "\r\n") {
if strings.HasPrefix(line, "ChannelStateDesc: ") {
state := strings.TrimSpace(strings.TrimPrefix(line, "ChannelStateDesc: "))
callStatus.UpdateCallStatus(state)
}
}
}我已经弄清楚了，代码如下： //服务器.go
parts := strings.split(line, ": ")
if len(parts) == 2 {
key := parts[0]
value := parts[1]
if key == "event" {
object.event = value
}
if key == "channelstate" {
object.channelstate = value
}
if key == "linkedid" {
object.linkedid = value
}
}
data.handleevent(object, activecalls)calls.go
package data
import (
"encoding/json"
"fmt"
)
type Data struct {
Event string `json:"Event"`
ChannelState string `json:"ChannelState"`
Linkedid string `json:"Linkedid"`
}
type ActiveCalls struct {
Count int `json:"active_calls"`
}
func HandleEvent(data Data, activeCalls
*ActiveCalls) {
if data.Event == "Newstate" {
fmt.Println(data.ChannelState)
if data.ChannelState == "6" {
activeCalls.Count++
fmt.Println("Newstate count active
calls", activeCalls.Count)
}
} else if data.Event == "Hangup" {
fmt.Println(data.ChannelState)
activeCalls.Count--
if activeCalls.Count < 0 {
activeCalls.Count = 0
}
fmt.Println("Newstate count active calls after hangup", activeCalls.Count)
}
}
func ActiveCallsToJSON(activeCalls *ActiveCalls) (string, error) {
jsonBytes, err := json.Marshal(activeCalls)
if err != nil {
return "", err
}
return string(jsonBytes), nil}
以上是如何从 Asterisk Manager 接口事件获取活动呼叫数量的详细内容。更多信息请关注PHP中文网其他相关文章！
