YouTube直播SDK集成（二）

一,前面已经知道了基础的环境配置，先看登录：
（1）首先要导入SDK，然后引入头文件

import GoogleSignIn

（2）然后触发登录按钮的时候进行是否需要登录的逻辑判断，进行登录

  //登录
  func googleSignIn(with viewController: UIViewController) {
        if isGoogleConnected {//已经登录
            presenter?.presentUserInfo()
            return
        }
        if GIDSignIn.sharedInstance().hasAuthInKeychain(){//本地缓存信息 再次授权
            GIDSignIn.sharedInstance().signInSilently()
        } else {// 登录
            cViewController = viewController
            presenter?.startActivity()
            let currentScopes: NSArray = GIDSignIn.sharedInstance().scopes as NSArray
            GIDSignIn.sharedInstance().scopes = currentScopes.adding(Auth.Scope)
            GIDSignIn.sharedInstance().signIn()
        }
    }
    
    //注销
    func signOut() {
        GIDSignIn.sharedInstance().signOut()
        GoogleOAuth2.sharedInstance.clearToken()
        userStorage.user = nil
    }

（3）创建直播 creade Broadcast
准备基础数据

You must specify a value for these properties:

snippet.title
snippet.scheduledStartTime
status.privacyStatus
You can set values for these properties:

snippet.title
snippet.description
snippet.scheduledStartTime
snippet.scheduledEndTime
status.privacyStatus
contentDetails.monitorStream.enableMonitorStream
contentDetails.monitorStream.broadcastStreamDelayMs
contentDetails.enableDvr
contentDetails.enableContentEncryption
contentDetails.enableEmbed
contentDetails.recordFromStart
contentDetails.startWithSlate
contentDetails.enableClosedCaptions

let title = "Big Fish Live video" //直播名称titile
let description = "Big Fish Test broadcast video"
let startDate = Helpers.dateAfter(Date(), after: (hour: 0, minute: 2, second: 0))//2分钟后开始直播

API:
POST https://www.googleapis.com/youtube/v3/liveBroadcasts
(4) create Live Stream

You must specify a value for these properties:

snippet.title
cdn.format
cdn.ingestionType
You can set values for these properties:

snippet.title
snippet.description
cdn.format
cdn.ingestionType
contentDetails.isReusable

API:https://developers.google.com/youtube/v3/live/docs/liveStreams/list

(5) Bind live stream

参数

"id":broadcastId 
"streamId":streamId 
"part":"id,snippet,contentDetails,status" 
"key": API_KEY in the infoplist

API:https://developers.google.com/youtube/v3/live/docs/liveBroadcasts/bind

返回数据

(6)get Live Broadcast 获取Broadcast信息
参数：

broadcastId

API:https://developers.google.com/youtube/v3/live/docs/liveBroadcasts/list
（7）get Live Stream

    "part":"id,snippet,cdn,status" 
    "id":liveStreamId 
    "key": API_KEY in the infoplist

(lldb) po liveStream
▿ LiveStreamModel
  - kind : "youtube#liveStream"
  - etag : "\"XI7nbFXulYBIpL0ayR_gDh3eu1k/iGgvEjOajAPRhRhyED1WrjYZZZs\""
  - id : "R0RSppD9pRo-RgkQNmNoqg1533956508322798"
  ▿ snipped : Snipped
    - publishedAt : "2018-08-11T03:01:48.000Z"
    - channelId : "UCR0RSppD9pRo-RgkQNmNoqg"
    - title : "Live video"
    - description : "Test broadcast video"
    - isDefaultStream : false
  ▿ cdn : CDN
    - format : "720p_hfr"
    - ingestionType : "rtmp"
    ▿ ingestionInfo : IngestionInfo
      - streamName : "rwz9-dkxq-3v84-8bv3"
      - ingestionAddress : "rtmp://a.rtmp.youtube.com/live2"
      - backupIngestionAddress : "rtmp://b.rtmp.youtube.com/live2?backup=1"
    - resolution : "720p"
    - frameRate : "60fps"
  ▿ status : Status
    - streamStatus : "inactive"
    ▿ healthStatus : HealthStatus
      - status : "noData"

最终 我们往获取到的地址推流即可

let streamUrl = "\(streamURL)/\(streamName)"

下一章写IOS 的rtmp推流
