如何修复node.js服务器上的bitmovin-javascript中的'HTTP Response Code was 403 Forbidden'错误

Question

我在node.js服务器上使用bitmovin-javascript。 我正在尝试在Firebase存储上为视频创建编码，并使用bitmovin-javascript API将输出保存到我​​的bitmovin帐户中。

我已经从旧的bitmovin api（v1）升级为javascript（现已弃用），并且正在实现当前的api（v2）。 但是每次我运行该代码时，它都显示HTTP请求失败：在我的终端控制台中， HTTP响应代码被禁止为403 。

我已经进行了交叉检查，并确保我正在从Firebase存储中读取的API密钥（accesss-key和secret-key）是有效密钥，并且bitmovin API密钥也是有效密钥。 bitmovin的输出ID也是有效的ID。

api生成输入和视频编解码 器配置 ， 音频编解码器配置和清单，但不生成输出或编码 。

该错误似乎是在api试图创建编码资源的时候发生的。

这是我的代码的样子：

const Bitmovin = require('bitmovin-javascript').default;


const start = async () => {
  const bitmovin = Bitmovin({ 'apiKey': 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' });

  // create the input
  const input = await bitmovin.encoding.inputs.gcs.create({
    name: 'Input',
    accessKey: 'GOOGXXXXXXXXXXXXXXXX',
    secretKey: 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
    bucketName: 'project-name.appspot.com'
  });

  // create the output
  const outputId = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX";

  // create the video and audio codec configurations
  const videoCodecConfig1 = await bitmovin.encoding.codecConfigurations.h264.create({
    name: 'H264 Codec Config',
    bitrate: 240000,
    width: 384,
    profile: 'HIGH'
  });

  const audioCodecConfig = await bitmovin.encoding.codecConfigurations.aac.create({
      name: 'my-aac-128kbit-cc',
      bitrate: 128000, // 128 KBit/s
      rate: 48000
  });

  // create the encoding resource
  const encoding = await bitmovin.encoding.encodings.create({
     name: 'Encoding',
     cloudRegion: 'AUTO',
     encoderVersion: '2.12.1'
  });

  // add the video and audio streams to the encoding
  const inputPath = 'https://firebasestorage.googleapis.com/v0/b/project-name.appspot.com/o/new%2Fvideos%2Fsample.mp4?alt=media&token=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX';

  const videoStreamConfig1 = {
    codecConfigId: videoCodecConfig1.id,
    inputStreams: [{
      inputId: input.id,
      inputPath: inputPath,
      selectionMode: 'AUTO'
    }]
  };

  const streamVideo1 = await bitmovin.encoding.encodings(encoding.id).streams.add(videoStreamConfig1);

  const audioStreamConfig = {
      codecConfigId: audioCodecConfig.id,
      inputStreams: [{
          inputId: input.id,
          inputPath: inputPath,
          selectionMode: 'AUTO'
      }]
  };
  const audioStream = await bitmovin.encoding.encodings(encoding.id).streams.add(audioStreamConfig);

  // add the video muxings to the encoding
  const segmentLength = 4;
  const outputPath = 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/' + Date.now();
  const segmentNaming = 'seg_%number%.m4s';
  const initSegmentName = 'init.mp4';

  const fmp4VideoMuxingConfig1 = {

      acl: [{

      }]
    }]
  };

  const videoMuxing1 = await bitmovin.encoding.encodings(encoding.id).muxings.fmp4.add(fmp4VideoMuxingConfig1);

  // add the audio muxing to the encoding
  const fmp4AudioMuxingConfig = {
    segmentLength,
    segmentNaming,
    initSegmentName,
    streams: [{
      streamId: audioStream.id
    }],
    outputs: [{

      acl: [{

      }]
    }]
  };

  const fmp4AudioMuxing = await bitmovin.encoding.encodings(encoding.id).muxings.fmp4.add(fmp4AudioMuxingConfig);

  //create the manifest
  const manifestConfig = {
    name: 'Manifest',
    manifestName: 'manifest.mpd',
    outputs: [{
      outputId: outputId,
      outputPath: outputPath,
      acl: [{
        permission: 'PUBLIC_READ'
      }]
    }]
  };

  const manifest = await bitmovin.encoding.manifests.dash.create(manifestConfig);
  const period = await bitmovin.encoding.manifests.dash(manifest.id).periods.add({});

  let videoAdaptationSet = {

  };

  let audioAdaptationSet = {
    lang: 'en'
  };

  videoAdaptationSet = await bitmovin.encoding.manifests
    .dash(manifest.id)

  await bitmovin.encoding.manifests

    .periods(period.id)
    .adaptationSets(audioAdaptationSet.id)
    .representations.fmp4
    .add(fmp4AudioRepresentation);

  // Adding Video Representation

  const fmp4VideoRepresentation1 = {

  await bitmovin.encoding.manifests
    .dash(manifest.id)
    .periods(period.id)
    .adaptationSets(videoAdaptationSet.id)
    .representations.fmp4
    .add(fmp4VideoRepresentation1);

  // start the encoding
  await bitmovin.encoding.encodings(encoding.id).start();


  // wait for the encoding to be finished
  await finish(encoding);

  //start and wait for the manifest to be finished
  await bitmovin.encoding.manifests.dash(manifest.id).start();

  console.log('Generating DASH manifest...');

  const waitForManifestToBeFinished = async () => {
    let manifestResponse;

    do {
      await bitmovin.encoding.manifests
          .dash(manifest.id)
          .status()
          .then(response => {
            console.log('DASH Manifest status is ' + response.status);
            manifestResponse = response;
          });

      await new Promise(resolve => setTimeout(resolve, 2000));
    }
    while (manifestResponse.status === 'RUNNING' || manifestResponse.status === 'CREATED');
  };

  await waitForManifestToBeFinished();

  console.log('Everything finished...');

  function getStatus(encoding) {
    return bitmovin.encoding.encodings(encoding.id).status();
  }

  function finish(encoding, interval = 5 * 1000, timeout = 5 * 60 * 1000) {
    let t, s = new Date();

    const check = (resolve, reject) => {
      clearTimeout(t);

      t = setTimeout(() => {
        getStatus(encoding)
          .then(current => {
            console.log('Encoding progress: ' + current.progress);

            if (current.status === 'FINISHED') {
              return resolve(current);
            }

            if (current.status === 'ERROR') {
              return reject('Encoding error');
            }

            if (new Date() - s >= timeout) {
              return reject('Timeout reached');
            }

            check(resolve, reject);
          });
      }, interval);
    }

    return new Promise((resolve, reject) => {
      check(resolve, reject);
    });
  }
  }
  start().catch(e => console.log(e.message));

我希望该API能够读取我的Firebase存储，对来自该存储的视频进行编码，将其存储在我的bitmovin输出下，为我提供一个到输出的bitmovin链接，以便可以将其保存到我自己的数据库中。

帮助将不胜感激。

到目前为止，我还没有注意到您提供的代码段有任何特定的问题。 但是，此问题可能是由另一个因素引起的，例如输入/输出设置或输入文件本身。

请随时联系support@bitmovin.com，并提供编码ID和输入文件，以便我们对此进行更详细的研究。
