问题描述

PutLiveChannel请求中Target节点的PlaylistName字段有误,长度超出接口限制。

问题原因

您发起了PutLiveChannel请求来创建一个LiveChannel,并在请求体XML中通过Target节点描述LiveChannel转储配置的各项参数,但是您提供的PlaylistName参数不符合接口要求。该参数用于指定生成的m3u8文件的名称。必须以.m3u8结尾, 长度范围为[6, 128],且不能包含/字符,默认值是playlist.m3u8

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 qn6q**************:77Dv****************
<?xml version="1.0" encoding="utf-8"?>
<LiveChannelConfiguration>
    <Description />
    <Status>enabled</Status>
    <Target>
        <Type>HLS</Type>
        <FragDuration>2</FragDuration>
        <FragCount>abc</FragCount>
        <PlaylistName>xxx...(此处省略200个字符)...xxx.m3u8</PlaylistName>
    </Target>
    <Snapshot>
        <RoleName>role_for_snapshot</RoleName>
        <DestBucket>bucketdest</DestBucket>
        <NotifyTopic>notifyTopic</NotifyTopic>
        <Interval>1</Interval>
     </Snapshot>
</LiveChannelConfiguration

上述请求中Target节点的PlaylistName子节点值长度过长,不是符合接口长度范围[6, 128]的要求,因此接口返回该错误。

解决方案

请确保请求体XMLTarget节点各项参数符合接口要求,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 qn6q**************:77Dv****************
<?xml version="1.0" encoding="utf-8"?>
<LiveChannelConfiguration>
    <Description />
    <Status>enabled</Status>
    <Target>
        <Type>HLS</Type>
        <FragDuration>2</FragDuration>
        <FragCount>3</FragCount>
        <PlaylistName>myplaylist.m3u8</PlaylistName>
    </Target>
    <Snapshot>
        <RoleName>role_for_snapshot</RoleName>
        <DestBucket>snapshotdest</DestBucket>
        <NotifyTopic>snapshotnotify</NotifyTopic>
        <Interval>1</Interval>
     </Snapshot>
</LiveChannelConfiguration
