我尝试使用下面链接中的Azure Media服务引用代码上传视频。
请求标题如下所示
Request: PUT /asset-967889d1-bb0d-4853-9e61-31777d9b3f4e/Wildlife.wmv?sv=2012-02-12&sr=c&si=39af4b60-16ac-4abe-8a2f-4fdf7a90e1f3&sig=pukmGXpkVJuD4zqFm6xoCRBgGWjphO8%2BP8BtfK0GUV4%3D&st=2017-06-15T17%3A20%3A18Z&se=2017-06-30T17%3A20%3A18Z&comp=blocklist HTTP/1.1

示例请求正文：
<?xml version="1.0" encoding="utf-8"?>
<BlockList><Latest>YmxvY2stMDAwMDAw</Latest>
<Latest>YmxvY2stMDAwMDAwMQ==</Latest>
</BlockList>
在响应正文中抛出错误：
<?xml version="1.0" encoding="utf-8"?><Error><Code>InvalidBlockList</Code><Message>The specified block list is invalid.
RequestId:0e320a80-0001-001f-06fb-e59187000000
Time:2017-06-15T17:21:29.5286217Z</Message></Error>
请指点解决此问题。
更新：我在第一个块ID中追加另一个0。
现在我的请求正文如下：
<?xml version="1.0" encoding="utf-8"?>
<BlockList>
<Latest>YmxvY2stMDAwMDAwMA==</Latest>
<Latest>YmxvY2stMDAwMDAwMQ==</Latest>
<Latest>YmxvY2stMDAwMDAwMg==</Latest>
<Latest>YmxvY2stMDAwMDAwMw==</Latest>
</BlockList>
在响应正文中引发相同的错误。
<?xml version="1.0" encoding="utf-8"?>
<Error><Code>InvalidBlockList</Code>
<Message>The specified block list is invalid.

答案 0 :(得分：1)
您收到此错误的原因是a.setSize(275, 180);
的长度不同。根据文档here（请参阅URI参数部分），块ID必须具有相同的长度。
如果我这样做：
block ids我得到Encoding.UTF8.GetString(Convert.FromBase64String("YmxvY2stMDAwMDAw"));
如果我对你的第二个区块ID做同样的事情：
block-000000我得到Encoding.UTF8.GetString(Convert.FromBase64String("YmxvY2stMDAwMDAwMQ=="));
的输出。
正如您所看到的，块ID长度为2不同（第一个是12个字符，第二个是13个字符）。请将第一个块ID更改为block-0000001（基本上附加另一个block-0000000）然后此错误应该消失。
