**FastAPI** is based on **OpenAPI**.

That's what makes it possible to have multiple automatic interactive documentation interfaces, code generation, etc.

OpenAPI has a way to define multiple security "schemes".

By using them, you can take advantage of all these standard-based tools, including these interactive documentation systems.

    checkNotNull(wrapperFunction);
    checkArgument(interfaceType.isInterface(), "%s isn't an interface", interfaceType);
    Method[] methods = getMostConcreteMethods(interfaceType);
    AccessibleObject.setAccessible(methods, true);
    for (Method method : methods) {
      // Interfaces can have default methods that aren't abstract.
      // No need to verify them.

///

Dessa forma:

* Será documentado como tal no esquema OpenAPI (e, portanto, nas interfaces do usuário):

The JSON Schemas of your models will be part of your OpenAPI generated schema, and will be shown in the interactive API docs:

	if err != nil {
		logger.FatalIf(err, "Unable to split host port %s", hostPort)
	}
	return xh.Name, xh.Port.String()
