Wenn Sie Felder aus Formularen statt JSON empfangen müssen, können Sie `Form` verwenden.

/// info

Um Formulare zu verwenden, installieren Sie zuerst <a href="https://andrew-d.github.io/python-multipart/" class="external-link" target="_blank">`python-multipart`</a>.

Z. B. `pip install python-multipart`.

## `Form` importieren

Importieren Sie `Form` von `fastapi`:

Bạn cũng có thể trả về Pydantic model (bạn sẽ thấy nhiều hơn về nó sau).

Có nhiều object và model khác nhau sẽ được tự động chuyển đổi sang JSON (bao gồm cả ORM,...). Thử sử dụng loại ưa thích của bạn, nó có khả năng cao đã được hỗ trợ.

## Tóm lại

* Import `FastAPI`.
* Tạo một `app` instance.
* Viết một **decorator cho đường dẫn toán tử** (giống như `@app.get("/")`).

    private void validatePasswordForm(final ProfileForm form, final VaErrorHook validationErrorLambda) {
        validate(form, messages -> {}, validationErrorLambda);

        if (!form.newPassword.equals(form.confirmNewPassword)) {
            form.newPassword = null;
            form.confirmNewPassword = null;
            throwValidationError(messages -> {
                messages.addErrorsInvalidConfirmPassword(GLOBAL);

    }

    /**

    @Execute
    @Secured({ ROLE })
    public HtmlResponse edit(final EditForm form) {
        validate(form, messages -> {}, this::asListHtml);
        final String id = form.id;

                                        <la:text styleId="name" property="name" styleClass="form-control"/>
                                    </div>
                                </div>
                                <div class="form-group row">

                                            key="labels.labeltype_value"/></label>

        validate(form, messages -> {}, () -> asEditTagsHtml(form.path, form.name));
        saveToken();
        return asEditTagsHtml(form.path, form.name);
    }

    /**
     * Updates the tags for a storage object.
     *
     * @param form the tag form containing updated tag information
     * @return HTML response redirecting to the storage list after update
     */
    @Execute

    /**
     * Creates a crawling configuration and returns to the config form.
     *
     * @param form the form containing crawling configuration data
     * @return HTML response redirecting to the config form
     */
    @Execute
    @Secured({ ROLE })
    public HtmlResponse crawlingConfig(final CrawlingConfigForm form) {
        validate(form, messages -> {}, () -> asHtml(path_AdminWizard_AdminWizardConfigJsp));

     *
     * @param form the create form
     * @return HTML response for the document creation form
     */
    @Execute
    @Secured({ ROLE })
    public HtmlResponse createnew(final CreateForm form) {
        saveToken();
        form.initialize();
        form.crudMode = CrudMode.CREATE;
        getDoc(form).ifPresent(entity -> {
            form.doc = fessConfig.convertToEditableDoc(entity);

Sie können mehrere `File`- und `Form`-Parameter in einer *Pfadoperation* deklarieren, aber Sie können nicht gleichzeitig auch `Body`-Felder deklarieren, welche Sie als JSON erwarten, da der Request den Body mittels `multipart/form-data` statt `application/json` kodiert.

Das ist keine Limitation von **FastAPI**, sondern Teil des HTTP-Protokolls.
