Method BindBody

tools/router/event.go:354–398

16mb BindBody unmarshal the request body into the provided dst. dst must be either a struct pointer or map[string]any. The rules how the body will be scanned depends on the request Content-Type. Currently the following Content-Types are supported: - application/json - text/xml, application/xml -

(dst any)
