If you want to secure your API, there are several better things you can do, for example:

   */

    webSocket: WebSocket,
    code: Int,
    reason: String,

  /**
   * Invoked when a web socket has been closed due to an error reading from or writing to the
   * network. Both outgoing and incoming messages may have been lost. No further calls to this
   * listener will be made.

  open fun onFailure(

    SCRIPT="$link"
  else

  fi
done

FESS_HOME=`dirname "$SCRIPT"`/..

# make FESS_HOME absolute
FESS_HOME=`cd "$FESS_HOME"; pwd`


# If an include wasn't specified in the environment, then search for one...
if [ "x$FESS_INCLUDE" = "x" ]; then

## OpenAPI Meta Verileri - Dokümantasyon

After you have tests, then you can upgrade the **FastAPI** version to a more recent one, and make sure that all your code is working correctly by running your tests.

If everything is working, or after you make the necessary changes, and all your tests are passing, then you can pin your `fastapi` to that new recent version.

Similar to making sure your application is run on startup, you probably also want to make sure it is **restarted** after failures.

### We Make Mistakes { #we-make-mistakes }

We, as humans, make **mistakes**, all the time. Software almost *always* has **bugs** hidden in different places. 🐛
