Body Limit

BodyLimit protects endpoints from unexpectedly large request bodies.

Quick start​

app.Use(middleware.BodyLimit(10 * middleware.MB))

Config​

app.Use(middleware.BodyLimitWithConfig(middleware.BodyLimitConfig{
	Limit: 10 * middleware.MB,
}))

Fields​

FieldMeaning
SkipperSkip the limit for selected requests
LimitRequired maximum size in bytes

Size helpers​

Zinc exposes convenient constants:

  • middleware.B
  • middleware.KB
  • middleware.MB
  • middleware.GB

Failure behavior​

When the body exceeds the configured limit, Zinc returns a *middleware.BodyLimitError.

That error includes:

  • Limit
  • Observed
  • Source

Source tells you whether the limit was exceeded from:

  • the request's Content-Length
  • actual body reads

The error unwraps to zinc.ErrRequestEntityTooLarge.
