【问题描述】：

目前在为 Agora 流启动云录制时遇到问题。

我正在使用颤振并创建了一个云功能来开始录制。

颤动：

 AgoraRtcEngine.onJoinChannelSuccess = (String channel, int uid, int elapsed) async {
  AgoraCloudRecording().startAgoraCloudRecording(channel, uid);
};

云功能：

export async function retrieveAgoraToken(data: any){

//Variables
const channel = data.channel;
const uid = data.uid;


//AGORA KEYS
const agoraDoc = await agoraDocRef.get();
const appID = agoraDoc.data()!.appID;
const customerID = agoraDoc.data()!.customerID;
const secret = agoraDoc.data()!.secret;
const agoraCredentials = Base64.encode(customerID + ":" + secret);   

//AWS
const awsDoc = await awsDocRef.get();
const awsAccessKey = awsDoc.data()!.accessKey;
const awsSecretKey = awsDoc.data()!.secretKey;

const reqHeaders = {"Authorization": "Basic" + agoraCredentials, "Content-type": "application/json"};
const acquireReqBody = {
    "cname": channel,
    "uid": "1",
    "clientRequest": {
      "resourceExpiredHour": 24
    }
  };
console.log(reqHeaders);


//GET RESOURCE ID
const acquireURL = 'https://api.agora.io/v1/apps/' + appID + '/cloud_recording/acquire';
const acquireResourceID = {
    method: 'POST',
    url:  encodeURI(acquireURL),
    headers: reqHeaders,
    body: JSON.stringify(acquireReqBody)
}

const resourceIDRequest = new Promise<any>((resolve, reject) => {
    request(acquireResourceID, function (error:any, res:any, body:any) {
      console.error('error:', error); // Print the error if one occurred
      console.log('statusCode:', res && res.statusCode); // Print the response status code if a response was received
      resolve(JSON.parse(body));
      reject('error');
      });
  });

const resourceIDResponse = await resourceIDRequest;
console.log(resourceIDResponse);

const resourceID = resourceIDResponse.resourceId;

console.log(resourceID);

//START RECORDING
const recordingReqBody = {
    "cname": channel,
    "uid": "1",
            "clientRequest": {
              "recordingConfig": {
                "maxIdleTime": 30,
                "streamTypes": 2,
                "channelType": 1,
                "videoStreamType": 0,
                "transcodingConfig": {
                  "height": 640,
                  "width": 360,
                  "bitrate": 500,
                  "fps": 15,
                  "mixedVideoLayout": 1,
                  "backgroundColor": "#FF0000"
                },
                "subscribeVideoUids": [
                    uid
                ],
                "subscribeAudioUids": [
                    uid
                ],
                "subscribeUidGroup": 0
              },
              "recordingFileConfig": {
                "avFileType": [
                  "hls"
                ]
              },
      "storageConfig": {
        "accessKey": awsAccessKey,
        "region": 1,
        "bucket": "recorded-live-streams",
        "secretKey": awsSecretKey,
        "vendor": 1,
        "fileNamePrefix": [
          "directory1",
          "directory2"
        ]
      }
    }
  };

  
  const startRecordingURL = encodeURI('https://api.agora.io/v1/apps/' + appID + '/cloud_recording/resourceid/' + resourceID + '/mode/mix/start');
  console.log(startRecordingURL);

  const startRecordingOptions = {
    method: 'POST',
    url:  startRecordingURL,
    headers: reqHeaders,
    body: JSON.stringify(recordingReqBody)
}

const startVideoRecordingReq = new Promise<any>((resolve, reject) => {
    request(startRecordingOptions, function (error:any, res:any, body:any) {
      console.error('error:', error); // Print the error if one occurred
      console.log('statusCode:', res && res.statusCode); // Print the response status code if a response was received
      resolve(JSON.parse(body));
      reject('error');
      });
  });

const startVidRecordingResponse = await startVideoRecordingReq;

console.log(startVidRecordingResponse);
}

我什至尝试开始录制添加令牌参数。我会使用这个库通过 NodeJS 生成令牌：https://github.com/AgoraIO/Tools/tree/master/DynamicKey/AgoraDynamicKey/nodejs

我可以成功从 Agora 获取 resourceID。但是，如果我尝试开始录制，则会收到 404 错误：'no Route match with those values'

【问题讨论】：

为了澄清和隔离问题，您能否让相同的代码在 Cloud Functions 之外工作？

【解决方案1】：

我在这里找到了document，它为您报告的错误提供了一些背景信息。

“没有与这些值匹配的路由”：此消息的一个可能原因是您在请求中输入了错误的 HTTP 方法，例如在应该是 POST 时使用了 GET。另一个可能的原因是您将请求发送到了错误的 URL。

【讨论】：

我正在使用 POST 方法，并且我拥有的 URL 似乎是正确的... 'api.agora.io/v1/apps/' + appID + '/cloud_recording/resourceid/' + resourceID + '/mode/mix/start'
我在Query api 中遇到了这个错误，我将Post 更改为Get 然后它给出了响应。但我收到了404: Resource not found 的回复。如果您对此有任何想法，请提供帮助。

【解决方案2】：

请确保通过 Agora 控制台为您的项目启用云录制。

要在您的项目上启用云录制，请访问 https://console.agora.io/cloud-recording 并从左上角的下拉列表中选择项目名称，点击 持续时间 云录制下方的链接，然后单击按钮以启用该项目的服务。

点击开启云录制后，会提示确认并发通道设置，默认为50，点击确定。启用后，您应该会看到启用的使用图。
