When a user needs to cancel a spot order, they can send a cancellation request to the smart contract, providing the corresponding order information. Upon receiving the request, the smart contract verifies the legality of the request, such as validating the order ID, user identity, etc. If the verification passes, the smart contract traverses the order list to find the matching order. Once the matching order is found, the smart contract updates the order status to cancelled and records the reason for cancellation in the order log. simultaneously, the smart contract sends a confirmation message to the user, informing them that the order has been successfully cancelled. Throughout this process,"}]}],"pr":"dbce167f48cd674947861099f38b9afe8794ab962cd6006d0a1c011c6d7a04c5"}
