Si integras tu API con un proveedor OAuth2, podrás autenticarte y regresar a la documentación de la API con las credenciales adquiridas. E interactuar con ella usando la autenticación real de OAuth2.

Swagger UI lo manejará detrás de escena para ti, pero necesita este auxiliar de "redirección".

### Crea una *path operation* para probarlo { #create-a-path-operation-to-test-it }

An example could be that you have an external authentication provider that you need to call.

You send it a token and it returns an authenticated user.

This provider might be charging you per request, and calling it might take some extra time than if you had a fixed mock user for tests.

You probably want to test the external provider once, but not necessarily call it for every test that runs.

## About security, APIs, and docs { #about-security-apis-and-docs }

Hiding your documentation user interfaces in production *shouldn't* be the way to protect your API.

That doesn't add any extra security to your API, the *path operations* will still be available where they are.

If there's a security flaw in your code, it will still exist.

    disabled = user_dict["disabled"],
    hashed_password = user_dict["hashed_password"],
)

## Den Token zurückgeben { #return-the-token }

### Quotes

1) Convert neutral double quotes («"») and English double typographic quotes («“» and «”») to French guillemets (««» and «»»).

2) In the French docs, guillemets are written without extra spaces: use «texte», not « texte ».

3) Do not convert quotes inside code blocks, inline code, paths, URLs, or anything wrapped in backticks.

Examples:

    Source (English):

        «««
        "Hello world"

 *
 * mavenBuild("<jdk>", "<profiles> <goals> <plugins> <properties>"
 *
 * @param jdk the jdk tool name (in jenkins) to use for this build
 * @param extraArgs extra command line args
 */
def mavenBuild(jdk, extraArgs) {
  script {
    try {
      withEnv(["JAVA_HOME=${tool "$jdk"}",
               "PATH+MAVEN=${tool "$jdk"}/bin:${tool "maven_3_latest"}/bin",

Esto es muy útil cuando necesitas:

* Tener lógica compartida (la misma lógica de código una y otra vez).
* Compartir conexiones a bases de datos.
* Imponer seguridad, autenticación, requisitos de roles, etc.
* Y muchas otras cosas...

Todo esto, mientras minimizas la repetición de código.

## Primeros Pasos { #first-steps }

Veamos un ejemplo muy simple. Será tan simple que no es muy útil, por ahora.

        // Since headerStart is 0 and dstIndex starts at 1 (after initial null), (1-0)%2=1, so alignment byte added
        // Total: 1 + 1 + 12*2 + 2 = 28 bytes
        byte[] dst = new byte[30]; // Use extra buffer space to avoid index errors
        int result = smbComOpenAndX.writeBytesWireFormat(dst, 0);
        assertEquals(28, result);
    }

    /**
     * Test writeBytesWireFormat method without Unicode.
