Can httppostrequest decoder be used only for standard decoding, and the data of playload cannot be decoded?

[heixiaoma]

Hello, I submit JSON data with playload. When JSON data contains =%, there will be an exception

And issue https://github.com/netty/netty/issues/6898 The problem is similar, but it is judged that the bug is not closed. I try to look at other people’s open source web code and find that stable frameworks use their own decoders. It should be noted that there are some problems with the httppostrequest decoder, including some bugs when uploading files locally My English may not be good enough to show this problem perfectly
