## Benutzerdefinierte Header hinzufügen

Es gibt Situationen, da ist es nützlich, dem HTTP-Error benutzerdefinierte Header hinzufügen zu können, etwa in einigen Sicherheitsszenarien.

Sie müssen das wahrscheinlich nicht direkt in ihrem Code verwenden.

Aber falls es in einem fortgeschrittenen Szenario notwendig ist, können Sie benutzerdefinierte Header wie folgt hinzufügen:

{* ../../docs_src/handling_errors/tutorial002.py hl[14] *}

func (db *DB) Save(value interface{}) (tx *DB) {
	tx = db.getInstance()
	tx.Statement.Dest = value

	reflectValue := reflect.Indirect(reflect.ValueOf(value))
	for reflectValue.Kind() == reflect.Ptr || reflectValue.Kind() == reflect.Interface {
		reflectValue = reflect.Indirect(reflectValue)
	}

	switch reflectValue.Kind() {
	case reflect.Slice, reflect.Array:
		if _, ok := tx.Statement.Clauses["ON CONFLICT"]; !ok {

     *
     * @param offset the offset to set
     */
    public void setOffset(final long offset) {
        this.offset = offset;
    }

    /**
     * Add RDMA channel information for direct memory access
     *
     * @param remoteKey remote memory key
     * @param address remote memory address
     * @param length length of memory region

    REDIRECT_LOCATION,
    /** Indicates processing a response. */
    PROCESS_RESPONSE,
    /** Indicates the crawling process has finished. */
    FINISHED_CRAWLING,

        throw e;
        // The execution of a task has ended abnormally.
        // We could have tasks left in the queue, so should perhaps try to restart a worker,
        // but then the Error will get delayed if we are using a direct (same thread) executor.
      }
    }

Je kunt er ook meer over lezen op de <a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">Wikipedia over omgevingsvariabelen</a>.

In veel gevallen is het niet direct duidelijk hoe omgevingsvariabelen nuttig zijn en hoe je ze moet toepassen. Maar ze blijven in veel verschillende scenario's opduiken als je aan het ontwikkelen bent, dus het is goed om er meer over te weten.
