从蓝图中获取 flask-restful 路由

Question

有没有办法获取蓝图中定义的路由？我知道这个 (http://flask.pocoo.org/snippets/117/) 片段存在，但需要初始化应用程序才能使用 url_map。有没有办法在没有应用程序的情况下查看路线？我正在用 flask-restful 开发一个 api，我想在没有应用程序的情况下显示蓝图中的路线，以保持其独立性。

Answer 1

利用 polyfunc 提供的信息，我得出了这个解决方案：

from flask import Blueprint, current_app, url_for
from flask_restful import Resource, Api

api_blueprint = Blueprint('api', __name__)
api = Api(api_blueprint)

@api.resource('/foo')
class Foo(Resource):
    def get(self):
        prefix = api_blueprint.name + '.'  # registered classes will have this as their prefix

        # Get current rules
        rules = current_app.url_map.iter_rules()

        # Get list from routes registered under the blueprint
        routes = [url_for(rule.endpoint) for rule in rules if rule.endpoint.startswith(prefix)]
