从零开始搭建音视频通话服务

这是我参与2022首次更文挑战的第6天，活动详情查看：2022首次更文挑战

前言

本地服务已经在ubuntu虚拟机中搭建完成了，但是媒体流的播放等还没弄，先不折腾了，先把初始化和登录弄一下。账号已经拿到了，服务也有了，可以试着登录。

集成linphone-sdk

使用pod集成

使用pod集成时，请大于5.0.48版本，最好使用最新的版本，在Podfile文件中加入下面这行。

pod 'linphone-sdk', '~> 5.0.48'

现在集成的是5.0.66版本

mac@macdeMacBook 1-LoginTutorial % pod install

Analyzing dependencies

Downloading dependencies

Installing linphone-sdk (5.0.66)

Generating Pods project

Integrating client project

Pod installation complete! There is 1 dependency from the Podfile and 1 total pod installed.

文件导入

从linphone官网下载linphone-sdk，直接拖入到项目中即可。

如何使用（Swift）

直接import linphonesw就可以使用linphone-sdk。

设置日志打印级别（Swift）

先设置日志打印级别，开发的时候一般都是这只debug。

LoggingService.Instance.logLevel = LogLevel.Debug

初始化Core（Swift）

通过工厂生成一个Core实例，然后调用start()即可。

var mCore: Core!

try? mCore = Factory.Instance.createCore(configPath: "", factoryConfigPath: "", systemContext: nil)

try? mCore.start()

添加代理（Swift）

添加代理用来接收登录的回调，登录回调的是onAccountRegistrationStateChanged会返回有core，账号信息，注册状态和提示消息，根据状态可以进行下一步操作。

var mRegistrationDelegate : CoreDelegate!

mRegistrationDelegate = CoreDelegateStub(onAccountRegistrationStateChanged: { (core: Core, account: Account, state: RegistrationState, message: String) in
NSLog("New registration state is \(state) for user id \( String(describing: account.params?.identityAddress?.asString()))\n")
    if (state == .Ok) {
        self.loggedIn = true
    } else if (state == .Cleared) {
        self.loggedIn = false
    }
})

mCore.addDelegate(delegate: mRegistrationDelegate)

发起登录（Swift）

设置好账号密码就可以发起登录了。在登录回调中可以收到登录的进度以及状态。

@Published var username : String = "user"
@Published var passwd : String = "pwd"
@Published var domain : String = "xxx.example.org"
@Published var loggedIn: Bool = false
@Published var transportType : String = "UDP"

do {

    var transport : TransportType
    if (transportType == "TLS") { transport = TransportType.Tls }
    else if (transportType == "TCP") { transport = TransportType.Tcp }
    else  { transport = TransportType.Udp }
    let authInfo = try Factory.Instance.createAuthInfo(username: username, userid: "", passwd: passwd, ha1: "", realm: "", domain: domain)
    let accountParams = try mCore.createAccountParams()
    let identity = try Factory.Instance.createAddress(addr: String("sip:" + username + "@" + domain))
    try! accountParams.setIdentityaddress(newValue: identity)
    let address = try Factory.Instance.createAddress(addr: String("sip:" + domain))
    try address.setTransport(newValue: transport)
    try accountParams.setServeraddress(newValue: address)
    accountParams.registerEnabled = true
    let account = try mCore.createAccount(params: accountParams)
    mCore.addAuthInfo(info: authInfo)
    try mCore.addAccount(account: account)
    mCore.defaultAccount = account
} catch { NSLog(error.localizedDescription) }

完整代码如下（Swift）


var mCore: Core!

@Published var coreVersion: String = Core.getVersion

var mRegistrationDelegate : CoreDelegate!

@Published var username : String = "user"

@Published var passwd : String = "pwd"

@Published var domain : String = "xxx.example.org"

@Published var loggedIn: Bool = false

@Published var transportType : String = "UDP"

init()

{

    LoggingService.Instance.logLevel = LogLevel.Debug

    try? mCore = Factory.Instance.createCore(configPath: "", factoryConfigPath: "", systemContext: nil)

    try? mCore.start()

    mRegistrationDelegate = CoreDelegateStub(onAccountRegistrationStateChanged: { (core: Core, account: Account, state: RegistrationState, message: String) in

        NSLog("New registration state is \(state) for user id \( String(describing: account.params?.identityAddress?.asString()))\n")

        if (state == .Ok) {

            self.loggedIn = true

        } else if (state == .Cleared) {

            self.loggedIn = false

        }

    })

    mCore.addDelegate(delegate: mRegistrationDelegate)

}

func login() {

    do {

        var transport : TransportType

        if (transportType == "TLS") { transport = TransportType.Tls }

        else if (transportType == "TCP") { transport = TransportType.Tcp }

        else  { transport = TransportType.Udp }

        let authInfo = try Factory.Instance.createAuthInfo(username: username, userid: "", passwd: passwd, ha1: "", realm: "", domain: domain)

        let accountParams = try mCore.createAccountParams()

        let identity = try Factory.Instance.createAddress(addr: String("sip:" + username + "@" + domain))

        try! accountParams.setIdentityaddress(newValue: identity)

        let address = try Factory.Instance.createAddress(addr: String("sip:" + domain))

        try address.setTransport(newValue: transport)

        try accountParams.setServeraddress(newValue: address)

        accountParams.registerEnabled = true

        let account = try mCore.createAccount(params: accountParams)

        mCore.addAuthInfo(info: authInfo)

        try mCore.addAccount(account: account)

        mCore.defaultAccount = account

    } catch { NSLog(error.localizedDescription) }

}
