help request: How to rewrite the request header before matching to the Consumer

[jinxin231]

Description

By using a custom plugin, dynamically create consumers and implement different limit count strategies on different consumers.

Because it is an online system and we do not want to change the current authentication strategy, we need to modify the existing authentication strategy in the plugin to match with a unique API key (choosing key-auth plugin), so it can match with the corresponding consumer.

The current issue is that proxy-write is not suitable for this scenario. How can we rewrite the request header?
