Question

我正在使用Flask Restless 0.17和Flask JWT作为应用程序的API部分。在应用程序的前端，我使用Flask WTF及其CSRF保护。

这会给Flask Restless带来问题，因为WTF希望在每个视图上都有一个CSRF令牌。我可以通过免除API的蓝图来解决我创建的端点，但无法弄清楚如何将其应用于Flask JWT created / auth URL。

API启动：

def init_app(app):
    def authenticate(username, password):
        user = User.query.filter_by(username=username).scalar()
        if user and username == user.username and \
                User.check_password(user, password):
            return user
        return None

    def load_user(payload):
        user = User.query.filter_by(id=payload['identity']).scalar()
        return user

    jwt = JWT(app, authenticate, load_user)

    @jwt_required()
    def auth_func(**kw):
        pass

    manager = flask_restless.APIManager(app, flask_sqlalchemy_db=db)

    bp = manager.create_api_blueprint(
        MyModel,
        methods=['GET'],
        url_prefix='/api/v1',
        preprocessors=dict(GET_SINGLE=[auth_func],
                           GET_MANY=[auth_func]),
        results_per_page=10,
    )

    # Here I can exempt this API endpoint.
    # But how do I exempt /auth which is created by Flask JWT?
    csrf_protect.exempt(bp)
    app.register_blueprint(bp)

我无法像上面那样弄清楚如何做到这一点，所以我关闭了WTF CSRF保护，然后在我们不在API端点时启用它。

settings.py

WTF_CSRF_CHECK_DEFAULT = False

app.py

def register_csrf(app):
    """
    Only enable CSRF protection on URLs that are not API related.
    :param app: The app
    """
    @app.before_request
    def check_csrf():
        if request.endpoint != 'api':
            csrf_protect.protect()

Flask Restless CSRF免除身份验证URL
