微信小程序上传

请求上传地址和凭证或STS。

请求上传地址和凭证
上传图片和上传视频获取上传地址和凭证所请求的API不同，如下所示：
- 上传视频：客户端向AppServer发送请求，AppServer通过OpenAPI向阿里云点播服务发送CreateUploadVideo请求。请求成功将返回上传地址、上传凭证以及VideoId，AppServer将结果返回给客户端。
- 上传图片：客户端向AppServer发送请求，AppServer通过OpenAPI向阿里云点播服务发送CreateUploadImage请求。请求成功将返回上传地址、上传凭证以及ImageURL，AppServer将结果返回给客户端。
请求STS
通过STS方式，客户端向AppServer发送请求，AppServer向阿里云STS服务请求临时STS凭证。请求成功将返回STS凭证，AppServer将结果返回给客户端。

初始化上传实例。

声明VODUpload初始化回调。

var uploader = new VODUpload({
       //阿里账号ID，必须有值
       userId:"0",
       //上传到点播的地域，默认值为'cn-shanghai'，//eu-central-1，ap-southeast-1
       region:"",
       //网络原因失败时，重新上传次数，默认为3
       retryCount: 3,
       //网络原因失败时，重新上传间隔时间，默认为2秒
       retryDuration: 2,
      //开始上传
      'onUploadstarted': function (uploadInfo) {
      },
      //文件上传成功
      'onUploadSucceed': function (uploadInfo) {
      },
      //文件上传失败
      'onUploadFailed': function (uploadInfo, code, message) {
      },
      //文件上传进度，单位：字节
      'onUploadProgress': function (uploadInfo, totalSize, loadedPercent) {
      },
      //上传凭证超时
      'onUploadTokenExpired': function (uploadInfo) {
      },
      //全部文件上传结束
      'onUploadEnd':function(uploadInfo){
       }
  });

初始化上传实例有两种方式，如下所示：

上传地址和凭证方式

说明推荐使用上传地址和凭证方式进行初始化。

请求获取的上传地址和凭证初始化时无需设置，在上传开始后触发的onUploadStarted回调中调用setUploadAuthAndAddress(uploadFileInfo, uploadAuth, uploadAddress,videoId);方法进行设置。

当token超时，会触发onUploadTokenExpired回调，需要调用resumeUploadWithAuth(uploadAuth)方法，设置新的上传凭证继续上传。

var uploader = new VODUpload({
       //阿里账号ID，必须有值
       userId:"0",
       //网络原因失败时，重新上传次数，默认为3
       retryCount: 3,
       //网络原因失败时，重新上传间隔时间，默认为2秒
       retryDuration: 2,
      //开始上传
      'onUploadstarted': function (uploadInfo) {
        log("onUploadStarted:" + uploadInfo.file.name + ", endpoint:" + uploadInfo.endpoint + ", bucket:" + uploadInfo.bucket + ", object:" + uploadInfo.object);
        //上传方式1，需要根据uploadInfo.videoId是否有值，调用点播的不同接口获取uploadauth和uploadAddress，如果videoId有值，调用刷新视频上传凭证接口，否则调用创建视频上传凭证接口
        if (uploadInfo.videoId) {
            //如果uploadInfo.videoId存在，调用刷新视频上传凭证接口
         }
         else{
            //如果uploadInfo.videoId不存在，调用获取视频上传地址和凭证接口
         }
        //从点播服务获取的uploadAuth、uploadAddress和videoId，设置SDK
         uploader.setUploadAuthAndAddress(uploadInfo, uploadAuth, uploadAddress,videoId);
      },
      //文件上传成功
      'onUploadSucceed': function (uploadInfo) {
        log("onUploadSucceed: " + uploadInfo.file.name + ", endpoint:" + uploadInfo.endpoint + ", bucket:" + uploadInfo.bucket + ", object:" + uploadInfo.object);
      },
      //文件上传失败
      'onUploadFailed': function (uploadInfo, code, message) {
        log("onUploadFailed: file:" + uploadInfo.file.name + ",code:" + code + ", message:" + message);
      },
      //文件上传进度，单位：字节
      'onUploadProgress': function (uploadInfo, totalSize, loadedPercent) {
          log("onUploadProgress:file:" + uploadInfo.file.name + ", fileSize:" + totalSize + ", percent:" + Math.ceil(loadedPercent * 100) + "%");
      },
      //上传凭证超时
      'onUploadTokenExpired': function (uploadInfo) {
          console.log("onUploadTokenExpired");
          //实现时，根据uploadInfo.videoId调用刷新视频上传凭证接口重新获取UploadAuth
          //从点播服务刷新的uploadAuth，设置到SDK里
          uploader.resumeUploadWithAuth(uploadAuth);
      },
      //全部文件上传结束
      'onUploadEnd':function(uploadInfo){
           console.log("onUploadEnd: uploaded all the files");
       }
  });

STS方式

请求获取的STS初始化时无需设置，而是在上传开始后触发的onUploadStarted回调中调用setSTSToken(uploadInfo, accessKeyId, accessKeySecret, secretToken);方法进行设置。

当token超时，会触发onUploadTokenExpired回调，需要调用resumeUploadWithSTSToken(accessKeyId, accessKeySecret, secretToken)方法，设置新的STS继续上传。

var uploader = new VODUpload({
       //网络原因失败时，重新上传次数，默认为3
       retryCount: 3,
       //网络原因失败时，重新上传间隔时间，默认为2秒
       retryDuration: 2,
      //开始上传
      'onUploadstarted': function (uploadInfo) {
        log("onUploadStarted:" + uploadInfo.file.name + ", endpoint:" + uploadInfo.endpoint + ", bucket:" + uploadInfo.bucket + ", object:" + uploadInfo.object);
        //获取STS Token，设置到SDK
         uploader.setSTSToken(uploadInfo, accessKeyId, accessKeySecret, secretToken);
      }
      //文件上传成功
      'onUploadSucceed': function (uploadInfo) {
        log("onUploadSucceed: " + uploadInfo.file.name + ", endpoint:" + uploadInfo.endpoint + ", bucket:" + uploadInfo.bucket + ", object:" + uploadInfo.object);
      },
      //文件上传失败
      'onUploadFailed': function (uploadInfo, code, message) {
        log("onUploadFailed: file:" + uploadInfo.file.name + ",code:" + code + ", message:" + message);
      },
      //文件上传进度，单位：字节
      'onUploadProgress': function (uploadInfo, totalSize, loadedPercent) {
          log("onUploadProgress:file:" + uploadInfo.file.name + ", fileSize:" + totalSize + ", percent:" + Math.ceil(loadedPercent * 100) + "%");
      },
      //上传凭证超时
      'onUploadTokenExpired': function (uploadInfo) {
          console.log("onUploadTokenExpired");
          //重新获取STS token，恢复上传
          uploader.resumeUploadWithSTSToken(accessKeyId, accessKeySecret, secretToken);
      },
      //全部文件上传结束
      'onUploadEnd':function(uploadInfo){
           console.log("onUploadEnd: uploaded all the files");
       }
  });

列表管理。

添加上传文件
需要使用wx.chooseImage、wx.chooseVideo选择文件。获取到选择的文件后，添加到上传列表中。
```
    wx.chooseVideo({
        success: function (res) {
            var file = {url: res.tempFilePath, coverUrl: res.thumbTempFilePath};
            var userData = '{"Vod":{}}';
            uploader.addFile(file, null, null, null, userData)
        }
    })
```
上传时，可以选择是否启用水印和优先级，userData是一个JSON对象字符串。第一级的Vod必须设置，Vod下面添加属性，userData支持的属性请参见点播服务的接口获取视频上传地址和凭证，接口示例如下：
```
var userData = '{"Vod":{"Title":"test","CateId":"234"}"}';
```
删除上传文件
index对应listFiles接口返回列表中元素的索引。
```
uploader.deleteFile(index);
```
取消单个文件上传
```
uploader.cancelFile(index);
```
恢复单个文件上传
```
uploader.resumeFile(index);
```
获取上传文件列表
```
uploader.listFiles();
```
清理上传文件列表
```
uploader.cleanList();
```

上传控制。

开始上传
```
uploader.startUpload();
```
停止上传
```
uploader.stopUpload();
```

上传凭证失效后恢复上传

uploader.resumeUploadWithAuth(uploadAuth);

设置上传地址和上传凭证
设置上传地址和上传凭证方法在onUploadstarted回调里调用，此回调的参数包含uploadInfo的值。
```
uploader.setUploadAuthAndAddress(uploadInfo,uploadAuth, uploadAddress, videoId);
```
设置STS Token
设置STS Token方法在onUploadstarted回调里调用，此回调的参数包含uploadInfo的值。
```
uploader.setSTSToken(uploadInfo, accessKeyId, accessKeySecret,secretToken);
```

上传STS Token失效后恢复上传

uploader.resumeUploadWithSTSToken(accessKeyId, accessKeySecret, secretToken, expireTime);
