使用JavaScript SDK上传文件

上传地址和凭证方式

设置上传地址和凭证需要调用setUploadAuthAndAddress，当凭证过期，会触发onUploadTokenExpired回调，需要调用resumeUploadWithAuth方法，设置新的凭证继续上传。

// 开始上传
onUploadstarted: function (uploadInfo) {
  // https://help.aliyun.com/document_detail/55408.html?spm=a2c4g.11186623.6.630.BoYYcY
  let refreshUrl = 'https://demo-vod.cn-shanghai.aliyuncs.com/voddemo/RefreshUploadVideo?BusinessType=vodai&TerminalType=pc&DeviceModel=iPhone9,2&UUID=59ECA-4193-4695-94DD-7E1247288&AppVersion=1.0.0&Title=haha1&FileName=xxx.mp4&VideoId=' + uploadInfo.videoId
  axios.get(refreshUrl).then(({data}) => {
    let uploadAuth = data.UploadAuth
    let uploadAddress = data.UploadAddress
    let videoId = data.VideoId
    uploader.setUploadAuthAndAddress(uploadInfo, uploadAuth, uploadAddress,videoId)
  })
},
// 上传凭证超时
onUploadTokenExpired: function (uploadInfo) {
  // 上传大文件超时, 如果是上传方式一即根据 UploadAuth 上传时
  // 需要根据 uploadInfo.videoId 调用刷新视频上传凭证接口(https://help.aliyun.com/document_detail/55408.html)重新获取 UploadAuth
  // 然后调用 resumeUploadWithAuth 方法, 这里是测试接口, 所以我直接获取了 UploadAuth
  let refreshUrl = 'https://demo-vod.cn-shanghai.aliyuncs.com/voddemo/RefreshUploadVideo?BusinessType=vodai&TerminalType=pc&DeviceModel=iPhone9,2&UUID=59ECA-4193-4695-94DD-7E1247288&AppVersion=1.0.0&Title=haha1&FileName=xxx.mp4&VideoId=' + uploadInfo.videoId
  axios.get(refreshUrl).then(({data}) => {
    let uploadAuth = data.UploadAuth
    uploader.resumeUploadWithAuth(uploadAuth)
    console.log('upload expired and resume upload with uploadauth ' + uploadAuth)
  })
  self.statusText = '文件超时...'
},

方法说明：

uploader.sertUploadAuthAndAddress(uploadInfo, uploadAuth, uploadAddress, videoId)
uploader.resumeUploadWithAuth(uploadAuth)

STS Token方式

设置STS Token需要调用setSTSToken，当STS Token失效时，会触发onUploadTokenExpired回调，需要调用resumeUploadWithSTSToken方法，设置新的STS Token继续上传。

 /*回调方法-开始上传*/
 onUploadstarted: function (uploadInfo) {
    let stsUrl = "***.***.stsUrl" /*获取STS Token 使用setSTSToken方法*/
    axios.get(stsUrl).then(({data}) => {
          var info = data.SecurityTokenInfo
          uploader.setSTSToken(uploadInfo, info.AccessKeyId, info.AccessKeySecret, info.SecretToken);
     })
 },
/*回调方法-凭证超时*/
 onUploadTokenExpired: function (uploadInfo) { 
     let stsUrl = "***.***.stsUrl"  /*刷新STS Token 使用resumeUploadWithSTSToken方法*/
     axios.get(stsUrl).then(({data}) => {
         var info = data.SecurityTokenInfo  
         uploader.resumeUploadWithSTSToken(info.AccessKeyId, info.AccessKeySecret, info.SecretToken);      
     })
 },

方法说明：

uploader.setSTSToken(uploadInfo, accessKeyId, accessKeySecret, secretToken)
uploader.resumeUploadWithSTSToken(accessKeyId, accessKeySecret, secretToken)

JavaScript 原生

 <form action="">
   <input type="file" name="file" id="files" multiple/>
 </form>
 
 <script>
   userData = '';
   document.getElementById("files")
    .addEventListener('change', function (event) {
      for(var i=0; i<event.target.files.length; i++) {
        //逻辑代码
        uploader.addFile(event.target.files[i]，null，null，null，null)
      }
    });
 </script>

Vue

 <template>
  <input type="file" id="fileUpload" @change="fileChange($event)">
 </template>

<script>
  export default {
    data () {
      return {
        file: null,
      }
    },
    methods: {
      fileChange (e) {
        this.file = e.target.files[0]
        if (!this.file) {
          alert("请先选择需要上传的文件!")
          return
        }
        var Title = this.file.name
        var userData = '{"Vod":{}}'
        if (this.uploader) {
          this.uploader.stopUpload()
        }
        // 请先初始化一个 uploader
        this.uploader = this.createUploader() 
        this.uploader.addFile(this.file, null, null, null, userData)
      },
    }
  }
</script>
