好吧，答案是否定的.实际上，这取决于您如何创建SAS令牌.

Well, the answer is both no and yes. It actually depends on how you created a SAS token.

假设您创建了SAS令牌而未使用共享访问策略，且该策略中指定了有效期，那么答案是否定的.令牌过期后，您将需要使用新的失效日期创建一个新的SAS令牌并使用它.因此，没有机制可以延长现有令牌的有效期.

Assuming you have created a SAS token without using a Shared Access Policy with expiry date specified in the policy, then the answer is no. Once a token has expired, you will need to create a new SAS token with new expiry date and use that. As such there's no mechanism to extend the expiry of an existing token.

如果您使用共享访问策略创建了SAS令牌，并且已定义了有效期，那么答案是肯定的..您只需在共享访问策略"中更改有效期，然后就可以使用相同的SAS令牌.

If you have created a SAS token using a Shared Access Policy and that has expiry date defined, then the answer is yes. You can simply change the expiry date in the Shared Access Policy and then the same SAS token can be used.
