可不可以不显示key

Json is originally unordered and requires a key to identify its ownership. If there is no key, the ownership of the value cannot be determined, so such a function will not appear again. It is more appropriate to meet your needs on the business side.
There should be none. In fact, this will not have much impact on your program. Just take the value.
