How to access the Request.Body after ShouldBind*() returns an error ?

[rstrlcpy]

To increase log-details I want to put into the log the data, that ShouldBind*() read from Request.Body before fail.

Replace c.Request.Body with a wrapped one by io.TeeReader or so.

Or you should use c.ShouldBindBodyWith instead of c.ShouldBind*, and c.Get(gin.BodyBytesKey) to access the original body.

see #1341
