/// info

`**second_user_data` şu anlama geliyor:

Key-Value çiftini direkt olarak  `second_user_data` dictionarysine kaydet , yaptığın şey buna eşit olacak: `User(id=4, name="Mary", joined="2018-11-30")`

## Code size { #code-size }

This example might seem verbose. Keep in mind that we are mixing security, data models, utility functions and *path operations* in the same file.

But here's the key point.

The security and dependency injection stuff is written once.

And you can make it as complex as you want. And still, have it written only once, in a single place. With all the flexibility.

func (r *Record) WriteJSON(writer io.Writer) error {
	var kvs jstream.KVS = make([]jstream.KV, 0, len(r.columnNames))
	for i, cn := range r.columnNames {
		if i < len(r.csvRecord) {
			kvs = append(kvs, jstream.KV{Key: cn, Value: r.csvRecord[i]})
		}
	}
	return json.NewEncoder(writer).Encode(kvs)
}

// Raw - returns the underlying data with format info.
func (r *Record) Raw() (sql.SelectObjectFormat, any) {

    private
    val jarArtifactRegex = Regex("""^(.*?)-\d+(\.\d+)*([.-][A-Za-z0-9]+)*\.jar$""")

    private val keepClassesByArtifacts: Map<String, Set<String>> by lazy {
        parameters.keepClassesByCoordinates.mapKeys { it.key.substringAfter(":") }
    }

    override fun transform(outputs: TransformOutputs) {
        val fileName = artifact.get().asFile.name
        val artifactName = extractArtifactName(fileName)

        // TODO: in a moment Maven stop pushing user properties to system properties (and maybe something more)
        // and allow multiple instances per JVM, this may become a pool? derive key based in invokerRequest?
        MavenContext result = residentContext.computeIfAbsent(
                "resident",
                k -> new MavenContext(invokerRequest, false, (MavenOptions)

/// info | Informação

Neste exemplo utilizamos cabeçalhos personalizados inventados `X-Key` e `X-Token`.

Mas em situações reais, como implementações de segurança, você pode obter mais vantagens em usar as [Ferramentas de segurança integradas (o próximo capítulo)](../security/index.md){.internal-link target=_blank}.
