发送连续查询时，Errr代码0随机回复。 [英] Errr code 0 is replied randomly When sending continuous query.

问题描述

当我尝试连续向Face API服务器发送一些查询时，

When I try to send some queries to Face API server continuously,

错误0代码随机回复。

以下代码是为使用该功能而构建的"身份"。

Following codes are built for using the function "Identity".

代码将一些（3）人注册到一个PersonGroup，尝试"身份"函数。

The code registers some (3) Person to a PersonGroup and try to the "Identity" function.

然而，函数是否成功取决于运气。

However, whether the function is success or not is dependent on a luck.

它有时会完成，有时会失败返回0代码。

It sometimes be done and sometime be failed returning 0 code.

因此，我想知道原因。为什么不能一致地但是随机地成功或失败？

Thus, I want to know the reason. Why do not success or fail consistently but randomly?

对于重新查询期间是否有一些限制，例如

Is there some restriction about re-querying period like

"你不能重新发送查询直到50毫秒后" ？

"You can't re-send a query until 50 milliseconds later" ?

感谢阅读和我等你的回答。

Thanks for reading and I'm waiting for your answer.

推荐答案

如果你在免费套餐上，你很可能达到配额限制。

If you're on the free tier, you are quite likely hitting the quota limits.

在你的包装器中，你应该为错误响应添加一个处理程序，特别是403/429。 如果您已超出配额，HTTP响应也应包含Retry-After标头。

In your wrapper, you should add a handler for error responses, 403/429's in particular.  The HTTP response should also contain a Retry-After header if you've exceeded your quota.
