问题描述

PutLiveChannel请求中包含冗余的Snapshot节点。

问题原因

您发起了PutLiveChannel请求来创建一个LiveChannel，但是请求体XML中包含不止一个Snapshot节点。

该节点用于描述高频截图操作Snapshot各项参数，接口仅允许包含一个名为Snapshot的节点。

问题示例

比如您发起了如下请求：

PUT /test-channel?live HTTP/1.1
Date: Wed, 24 Aug 2016 11:11:28 GMT
Content-Length: xxx
Host: test-bucket.oss-cn-hangzhou.aliyuncs.com
Authorization: OSS YJjHK****:hvwOZJRh8toAj3DZvtsuPgf+a****
<?xml version="1.0" encoding="utf-8"?>
<LiveChannelConfiguration>
    <Description />
    <Status>enabled</Status>
    <Target>
        <Type>HLS</Type>
        <FragDuration>2</FragDuration>
        <FragCount>3</FragCount>
    </Target>
    <Snapshot>
        <RoleName>role_for_snapshot</RoleName>
        <DestBucket>snapshotdest</DestBucket>
        <NotifyTopic>snapshotnotify</NotifyTopic>
        <Interval>1</Interval>
     </Snapshot>
     <Snapshot>
        <RoleName>role2_for_snapshot</RoleName>
        <DestBucket>snapshotdest2</DestBucket>
        <NotifyTopic>snapshotnotify</NotifyTopic>
        <Interval>1</Interval>
     </Snapshot>
</LiveChannelConfiguration

上述请求中有两个Snapshot节点，不满足接口的要求，所以接口返回该错误。

解决方案

请确保请求体XML中仅存在一个Snapshot节点，比如：

PUT /test-channel?live HTTP/1.1
Date: Wed, 24 Aug 2016 11:11:28 GMT
Content-Length: xxx
Host: test-bucket.oss-cn-hangzhou.aliyuncs.com
Authorization: OSS YJjHK****:hvwOZJRh8toAj3DZvtsuPgf+a****
<?xml version="1.0" encoding="utf-8"?>
<LiveChannelConfiguration>
    <Description />
    <Status>enabled</Status>
    <Target>
        <Type>HLS</Type>
        <FragDuration>2</FragDuration>
        <FragCount>3</FragCount>
    </Target>
    <Snapshot>
        <RoleName>role_for_snapshot</RoleName>
        <DestBucket>snapshotdest</DestBucket>
        <NotifyTopic>snapshotnotify</NotifyTopic>
        <Interval>1</Interval>
     </Snapshot>
</LiveChannelConfiguration
