Struct LogAppend

modules/caddyhttp/logging/logappend.go:36–53

LogAppend implements a middleware that takes a key and value, where the key is the name of a log field and the value is a placeholder, or variable key, or constant value to use for that field.

// the key is the name of a log field and the value is a placeholder,
// or variable key, or constant value to use for that field.
type LogAppend struct {
	// Key is the name of the log field.
	Key string `json:"key,omitempty"`

	// Value is the value to use for the log field.
	// If it is a placeholder (with surrounding `{}`),
	// it will be evaluated when the log is written.
	// If the value is a key that exists in the `vars`
	// map, the value of that key will be used. Otherwise
	// the value will be used as-is as a constant string.
	Value string `json:"value,omitempty"`

	// Early, if true, adds the log field before calling
	// the next handler in the chain. By default, the log
	// field is added on the way back up the middleware chain,
	// after all subsequent handlers have completed.
	Early bool `json:"early,omitempty"`
}
