Function BindBody

bind.go:68–111

BindBody binds request body contents to bindable object NB: then binding forms take note that this implementation uses standard library form parsing which parses form data from BOTH URL and BODY if content type is not MIMEMultipartForm See non-MIMEMultipartForm: https://golang.org/pkg/net/http/#Requ

(c *Context, target any)

	req := c.Request()
	if req.ContentLength == 0 {
		return
	}

	// mediatype is found like `mime.ParseMediaType()` does it
	base, _, _ := strings.Cut(req.Header.Get(HeaderContentType), ";")
	mediatype := strings.TrimSpace(base)

	switch mediatype {
