Gin How to get text/plain parameters?

• With issues:
• The client initiates the request using post
• Content-Type is: text/plain

• The request data is json, but encrypted with aes, so the type is text

• Questions：

• 1. How to get to the request parameters? raw data (Text) in the Body
• 1. Can I use Model binding and validation after decrypting Text into json? How should I use it?

Thanks
