Do commit transactions have to be packaged?

I tried #5341 but in the fourth step
I can't use RPC API calls
Use push_transaction directly to report the error below

PS :I feel like EOS is the hardest thing I've ever connected to,Providing apis is too difficult

Yes, transactions are only accepted in packed format. There is now support in cleos to pack a JSON format transaction for you, returning the packed form. There are third party libraries that can do it. And one of the APIs can do it. See cleos convert for help.
