バージョン 0.121.0 で、`yield` を使う依存関係に対して `Depends(scope="function")` がサポートされました。

`Depends(scope="function")` を使うと、`yield` の後の終了コードは、クライアントへレスポンスが返される前、*path operation 関数* が終了した直後に実行されます。

そして、`Depends(scope="request")`（デフォルト）を使う場合、`yield` の後の終了コードはレスポンス送信後に実行されます。

詳しくはドキュメント「[`yield` を使う依存関係 - 早期終了と `scope`](../tutorial/dependencies/dependencies-with-yield.md#early-exit-and-scope)」を参照してください。

    public void addField(final String key, final Object value) {
        fields.put(key, value);
    }

    public String getLogMessage() {
        return getUrl();
    }

    @Override
    public Map<String, Object> toSource() {
        final Map<String, Object> sourceMap = super.toSource();
        if (fields != null) {
            sourceMap.putAll(fields);
        }
        return sourceMap;
    }

    @Override

                return fields;
            }

Abhängigkeiten mit `yield` haben sich im Laufe der Zeit weiterentwickelt, um verschiedene Anwendungsfälle abzudecken und einige Probleme zu beheben, hier ist eine Zusammenfassung der Änderungen.

### Abhängigkeiten mit `yield` und `scope` { #dependencies-with-yield-and-scope }

The files and form fields will be uploaded as form data and you will receive the files and form fields.

And you can declare some of the files as `bytes` and some as `UploadFile`.

/// warning

	elapsed := time.Since(begin)
	sql, rows := fc()
	fields := []slog.Attr{
		slog.String("duration", fmt.Sprintf("%.3fms", float64(elapsed.Nanoseconds())/1e6)),
		slog.String("sql", sql),
	}

	if rows != -1 {
		fields = append(fields, slog.Int64("rows", rows))
	}

	switch {
	case err != nil && (!l.IgnoreRecordNotFoundError || !errors.Is(err, ErrRecordNotFound)):
		fields = append(fields, slog.String("error", err.Error()))

	}

	switch reflectValue.Kind() {
	case reflect.Map:
		results = [][]interface{}{make([]interface{}, len(fields))}
		for idx, field := range fields {
			mapValue := reflectValue.MapIndex(reflect.ValueOf(field.DBName))
			if mapValue.IsZero() {
				mapValue = reflectValue.MapIndex(reflect.ValueOf(field.Name))
			}
			results[0][idx] = mapValue.Interface()
		}

For example, in one of the ways the OAuth2 specification can be used (called "password flow") it is required to send a `username` and `password` as form fields.

The <dfn title="specification">spec</dfn> requires the fields to be exactly named `username` and `password`, and to be sent as form fields, not JSON.
