【问题描述】:
我正在使用 SDK for java 来创建 SAS 来访问 blob。 这是代码:
SharedAccessBlobPolicy policy = new SharedAccessBlobPolicy();
policy.setPermissionsFromString("r");
Calendar date = Calendar.getInstance();
Date expire = new Date(date.getTimeInMillis() + (expirationMinutes * 60000));
Date start = new Date(date.getTimeInMillis());
policy.setSharedAccessExpiryTime(expire);
policy.setSharedAccessStartTime(start);
return blob.getUri().toString()+"?"+blob.generateSharedAccessSignature(policy, externalFileName);
但是当我尝试使用 url 访问 blob 时,我收到此错误:
<Error>
<Code>AuthenticationFailed</Code>
<Message>
Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature. RequestId:f1f169d2-0001-003f-115a-3be1d6000000 Time:2016-11-10T13:57:14.6192554Z
</Message>
<AuthenticationErrorDetail>
SAS identifier cannot be found for specified signed identifier
</AuthenticationErrorDetail>
</Error>
我在 NET 中为同一个 blob 做同样的事情,结果 url(有效)与我在这里得到的不同:
不起作用(java):

我该如何解决这个问题?
【问题讨论】:
-
您在上面提到的两个 SAS URL 中,您能分辨出哪个有效吗?
-
第二个,我会添加到问题中
