JSON parsing failed about mux

[zorro0799]

I tested that and everything works well for me. When I make the POST request with that data, I receive a response like this:

{
    "id": "42982700",
    "isbn": "4545454",
    "title": "Book Three"
}

And also I added log to check the errors when encode the json.

	err := json.NewEncoder(w).Encode(book)
	if err != nil {
		log.Println(err)
	}

Thank you for your answer

I am not able to reproduce your error using the following curl command:
curl --header "Content-Type: application/json" --request POST --data '{"isbn":"4545454","title":"Book Three","author":{"firstname":"Harry","lastname":"White"}}' http://localhost:8000/books

Can you provide the actual error that you are getting?

It could be a problem with your postman setup, I am guessing this is what you are using?

可能是你的postman设置有问题，我猜你用的是这个？ https://www.postman.com/

Indeed, I am using postman, my environment is,
macos 12.6.8, go version go1.21.0
I tried to use RapidApi to simulate the post request, the result is correct, but the shopping store is always lost with postman

Does postman persist your application? Does it keep it running in the background? If not, and it restarts it for every request, that would remove the data that you just submitted from memory since you are not using a persistent data store.

I have never used postman so I have no idea how it works, but it seems like this is not an issue with the mux library.

I confirm that I clean up the process every time I test, and then run a new instance, the same program, simulated with other tools, such as RApidApi (Paw), there is no problem, it seems to be a problem with postman, thank you for your answer
