FYI: code 106 "Illegal sign" can mean "the key's project is not approved yet" - how to tell it apart + two policy questions (long-term personal use / token validity)

Hello and a very warm welcome to the forum.

@Stephen guo

my project has been “pending review” for 26 days

For non-paying corporate/individual developers, only the default project is supported. As I mentioned in another post: Project approval

@Stephen guo

Token validity. The token response returns expiresIn = 3600 (1 hour).

It’s the same for me. The access token is only valid for one hour. With the refresh token, which I think is valid for 30 days by default, you can obtain a new access token without having to go through the authentication process again.

Signature reproduced byte-for-byte against the sample in the API guide

I’m not sure right now, but I think the example in the documentation was wrong. If I remember correctly, you have to do it exactly as described, and not the way the example suggests.
