The difference between Urlencoder.encode and encodeURIComponent in Java

Background information:

1) encodeURIComponent and decodeuricomponent used in front

2) Urlencoder.encode and Urldecoder.decode used in the background

Knowledge Points:

1) The difference between encodeURIComponent and Urlencoder.encode is that the former does not encode the following five symbols

! %21   
'%27   
(%28   
)%29   
~%7e

2 decodeURIComponent and Urldecoder.decode can not see the difference for a while

Explain:

Before and after the interactive transmission of data in the process, if it contains! ' () ~, the same content will transmit different coding results, but each other can decode. In the specific application, if there is a comparison of the logic before and after the code, it is best to measure these symbols. If the programming environment is the best solution to this problem, you might want to think about patching.
