java SpringBoot 集成阿里云视频直播完成直播功能

经历了几天的周折，近期才把项目完成，在这里与大家分享一下踩坑之路，也方便日后有类似项目，可以借阅一番

开发直播前先满足已下条件

1.开通视频直播功能

2.购买好了OSS存储

3.购买两个域名并且备案好,一个用来拉流,一个用来播流,

4.建议CNAM加速也设置好这样直播没那么卡

该项目是一个H5直播，采用m3u8格式完成直播的展示。通过推流地址，借助第三方推流工具实现直播效果，比如：OBS 或者一些微信小程序小推流。。等等

项目介绍：根据域名生成推流、播流地址，推流回调，检查推流状态。直播视频存储至OSS，视频回调，统计当前在线人数等等

项目需要：需要现在阿里云上配置你的域名，推流域名，播流域名，推流回调地址，OSS存储，播流跨域问题等等

进入正题：
根据推拉域名生成推流地址与播流地址

配置pom文件

<!--阿里云直播--><dependency><groupId>com.aliyun</groupId><artifactId>aliyun-java-sdk-core</artifactId><version>4.4.6</version></dependency><dependency><groupId>com.aliyun</groupId><artifactId>aliyun-java-sdk-live</artifactId><version>3.8.0</version></dependency><!-- Hutool工具包 --><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>4.0.12</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.48</version></dependency>

}

通过GetMapping 生成推流拉流地址

 @Resourceprivate AliYunConfig aliyunConfig;/*** 生成推流播流地址* sourceId  在这里我将它设置为房间号*/@GetMapping("/save_Live")public void save_Live(HttpServletRequest request, @RequestParam("sourceId") String sourceId){try {//生成推流地址String pushUrl = AliYunUtil.createPushUrl(sourceId, aliyunConfig);//生成播流地址String pullUrl = AliYunUtil.createPullUrl(sourceId, aliyunConfig);} catch (Exception e) {e.printStackTrace();}}

如果你的播流地址，存在跨域问题，请在阿里云上配置HTTP响应头，这里添加一个*号即可

现在开始走回调接口，这里需要你在阿里云上配置你的回调地址，是以http开头的

推流地址接口同样也是GET形式的阿里云返回的参数定义可以参考：https://help.aliyun.com/document_detail/84943.html?spm=a2c4g.11186623.2.27.44c63dd286Dtq1#concept-84943-zh

 /*** 推流地址回调接口 根据返回状态值进行业务处理*/@GetMapping("/callBackPath")public void test(HttpServletRequest request){/*** 返回参数* action:[publish].......*/try {Map<String, String[]> parameterMap = request.getParameterMap();ApiLiveModel model = JSONObject.parseObject(JSON.toJSONString(parameterMap),ApiLiveModel.class);// 实现效果   根据回调接口 publish_done：关闭直播 publish 开启直播if (model != null){String action = model.getAction().get(0); //获取直播状态值String houseId = model.getId().get(0); //获取直播房间号if (action.equals("publish")){log.info("开启直播状态");//业务处理}else if (action.equals("publish_done")){log.info("关闭直播状态");//业务处理}}}catch (Exception e){e.printStackTrace();}}

定义返回参数的model类

import java.util.List;public class ApiLiveModel {private List<String> action;private List<String> ip;private List<String> id;private List<String> app;private List<String> appname;private List<String> time;private List<String> usrargs;private List<String> node;public List<String> getAction() {return action;}public void setAction(List<String> action) {this.action = action;}public List<String> getIp() {return ip;}public void setIp(List<String> ip) {this.ip = ip;}public List<String> getId() {return id;}public void setId(List<String> id) {this.id = id;}public List<String> getApp() {return app;}public void setApp(List<String> app) {this.app = app;}public List<String> getAppname() {return appname;}public void setAppname(List<String> appname) {this.appname = appname;}public List<String> getTime() {return time;}public void setTime(List<String> time) {this.time = time;}public List<String> getUsrargs() {return usrargs;}public void setUsrargs(List<String> usrargs) {this.usrargs = usrargs;}public List<String> getNode() {return node;}public void setNode(List<String> node) {this.node = node;}
}

视频存储至阿里云OSS，需要配置Bucket，然后在域名管理，录制配置中添加配置

这样你的直播视频，就存放至阿里云上了，在这里有一个问题需要解决，m3u8格式的在线预览，需要配置一下跨域问题，不然无法播放。参考地址：https://help.aliyun.com/document_detail/31903.html?spm=a2c4g.11174283.6.1124.369f7da2kWLpA2

接下来就是视频回调了，同样也需要在阿里云配置你的视频回调接口，这里也是http开头的

接下来就是代码片段了，具体的返回参数，请参考：https://help.aliyun.com/document_detail/84935.html?spm=5176.13910061.0.0.6b2b7018cRAX1h&aly_as=qJRVAQTxQ

//录制视频存储到OSS 回调接口@PostMapping("/api_p/addLive")public void addLive(@RequestBody ApiSaveLiveModel model) throws IOException {try{/*** 返回参数* {*   "domain": "live.aliyunlive.com",*   "app": "live",*   "stream": "hello",*   "uri": "live/hello/0_2017-03-08-23:09:46_2017-03-08-23:10:40.flv",*   "duration": 69.403,*   "start_time": 1488985786,*   "stop_time": 1488985840* }* 具体参数详情请参考：https://help.aliyun.com/document_detail/84935.html?spm=5176.13910061.0.0.6b2b7018cRAX1h&aly_as=qJRVAQTxQ*/log.info("保存作品成功");}catch (Exception e){log.info("保存作品失败");e.printStackTrace();}}

回调参数model

public class ApiSaveLiveModel {/*** domain : live.aliyunlive.com* app : live* stream : hello* uri : live/hello/0_2017-03-08-23:09:46_2017-03-08-23:10:40.flv* duration : 69.403* start_time : 1488985786* stop_time : 1488985840*/private String domain;private String app;private String stream;private String uri;private double duration;private int start_time;private int stop_time;public String getDomain() {return domain;}public void setDomain(String domain) {this.domain = domain;}public String getApp() {return app;}public void setApp(String app) {this.app = app;}public String getStream() {return stream;}public void setStream(String stream) {this.stream = stream;}public String getUri() {return uri;}public void setUri(String uri) {this.uri = uri;}public double getDuration() {return duration;}public void setDuration(double duration) {this.duration = duration;}public int getStart_time() {return start_time;}public void setStart_time(int start_time) {this.start_time = start_time;}public int getStop_time() {return stop_time;}public void setStop_time(int stop_time) {this.stop_time = stop_time;}@Overridepublic String toString() {return "ApiSaveLiveModel{" +"domain='" + domain + '\'' +", app='" + app + '\'' +", stream='" + stream + '\'' +", uri='" + uri + '\'' +", duration=" + duration +", start_time=" + start_time +", stop_time=" + stop_time +'}';}
}

接下来就是根据当前播流地址，统计在线人数，统计HLS直播的在线人数, 我们需要客户端在请求的参数中带上唯一标识用户的uuid，在阿里云cdn使用的默认参数是aliyun_uuid，言下之意就是每当用户访问的时候，会携带这个uuid，通过这个uuid 来获取当前播流域名的在线人数

重要说明：统计m3u8格式的在线人数，需要通过阿里云工单申请

具体的参数可以找阿里云人工要一份，是PDF版，网上也有博客，但是我找不到了

//根据播流地址 查询当前在线人数public static Integer getPeopleSum() throws ClientException {/*** 返回参数**  time : 2020-04-20T03:40:00Z*  requestId : A76B853C-AB5A-4F02-96C5-BDAB1A485FAC*  usageData : [{"domainName":"boliu.comwinwin.com","streamInfos":[{"streamName":"/jingbei/82889.m3u8","infos":[{"downFlow":609.5467,"rate":"origin","online":1}]}]}]**  online：指的是当前的在线人数**/try{DescribeHlsLiveStreamRealTimeBpsDataRequest listRequest2 = new DescribeHlsLiveStreamRealTimeBpsDataRequest();listRequest2.setDomainName("boliu.comwinwin.com"); //播流域名listRequest2.setTime(getTime());  //UTC格式当前时间           归属地DefaultProfile profile = DefaultProfile.getProfile("cn-beijing", "LTAI4G84ApyG4K1x4v9JHaXC", "d4iWslw08vidnqtYB8IpaHLLfsVp9e");IAcsClient iAcsClient = new DefaultAcsClient(profile);//配置的参数DescribeHlsLiveStreamRealTimeBpsDataResponse response = iAcsClient.getAcsResponse(listRequest2);//获取直播人数       List<DescribeHlsLiveStreamRealTimeBpsDataResponse.UsageDataPerDomain> usageDatas = usageDatasResponse.getUsageData();//获取直播状态        for (DescribeHlsLiveStreamRealTimeBpsDataResponse.UsageDataPerDomain usageData : usageDatas) {     if (usageData.getDomainName().equals("播流域名(补全)")) {//获取阿里云返回的结果，根据结果处理得到当前播放流下在线人数String str = new Gson().toJson(response);ApiPersonSumModel mode = JSON.parseObject(str, ApiPersonSumModel.class);return 0;}catch (Exception e){return 0;}}/*** 获取当前在线时间  UTC 格式时间* @return*/public static String getTime(){Date date = new Date();// 获取当前时间Calendar calendar = Calendar.getInstance();calendar.setTime(date);int zoneOffset = calendar.get(Calendar.ZONE_OFFSET);int dstOffset = calendar.get(Calendar.DST_OFFSET);calendar.add(Calendar.MILLISECOND, -(zoneOffset + dstOffset));long timeInMillis = calendar.getTimeInMillis();SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");return df.format(timeInMillis);}

返回参数的model类

import java.util.List;public class ApiPersonSumModel {/*** time : 2020-04-20T03:40:00Z* requestId : A76B853C-AB5A-4F02-96C5-BDAB1A485FAC* usageData : [{"domainName":"boliu.comwinwin.com","streamInfos":[{"streamName":"/jingbei/82889.m3u8","infos":[{"downFlow":609.5467,"rate":"origin","online":1}]}]}]*/private String time;private String requestId;private List<UsageDataApiPersonSumModel> usageData;public String getTime() {return time;}public void setTime(String time) {this.time = time;}public String getRequestId() {return requestId;}public void setRequestId(String requestId) {this.requestId = requestId;}public List<UsageDataApiPersonSumModel> getUsageData() {return usageData;}public void setUsageData(List<UsageDataApiPersonSumModel> usageData) {this.usageData = usageData;}public static class UsageDataApiPersonSumModel {/*** domainName : boliu.comwinwin.com* streamInfos : [{"streamName":"/jingbei/82889.m3u8","infos":[{"downFlow":609.5467,"rate":"origin","online":1}]}]*/private String domainName;private List<StreamInfosApiPersonSumModel> streamInfos;public String getDomainName() {return domainName;}public void setDomainName(String domainName) {this.domainName = domainName;}public List<StreamInfosApiPersonSumModel> getStreamInfos() {return streamInfos;}public void setStreamInfos(List<StreamInfosApiPersonSumModel> streamInfos) {this.streamInfos = streamInfos;}public static class StreamInfosApiPersonSumModel {/*** streamName : /jingbei/82889.m3u8* infos : [{"downFlow":609.5467,"rate":"origin","online":1}]*/private String streamName;private List<InfosApiPersonSumModel> infos;public String getStreamName() {return streamName;}public void setStreamName(String streamName) {this.streamName = streamName;}public List<InfosApiPersonSumModel> getInfos() {return infos;}public void setInfos(List<InfosApiPersonSumModel> infos) {this.infos = infos;}public static class InfosApiPersonSumModel {/*** downFlow : 609.5467* rate : origin* online : 1*/private double downFlow;private String rate;private int online;public double getDownFlow() {return downFlow;}public void setDownFlow(double downFlow) {this.downFlow = downFlow;}public String getRate() {return rate;}public void setRate(String rate) {this.rate = rate;}public int getOnline() {return online;}public void setOnline(int online) {this.online = online;}}}}
}

定时器查询录制保存的视频

至此阿里云视频直播，推拉流、推流回调、视频存储、存储回调、各项配置、统计在线人数，就搞定了！

经过跟阿里云工单讨教的答案，以及自己在博客上找的资源，最终整理了一篇关于阿里云开发直播的东西。
