找不到 Flask REST 蓝图

Question

我正在尝试拆分在不同组件中使用 Flask、Blueprint 和 REST 的应用程序。但是我无法让 api 工作。

结构如下：

restml
|-> __init__.py
|-> app.py
\-> resources
    |-> __init__.py
    \-> hello.py

我的restml/__init__.py是：

from flask import Flask
from flask_restful import Api

from restml.resources import hello

app = Flask(__name__)


app.register_blueprint(hello.blueprint)

if __name__ == '__main__':
    app.run(debug=True)

我的restml/resources/hello.py是：

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

blueprint = Blueprint('hello', __name__)
api = Api()

class Hello(Resource):
    def get(self):
        return {
           "hello world"
        }

api.add_resource(Hello, '/api/hello', endpoint='hello')

当我运行应用程序一切启动时，但 curl 无法从 url http://localhost/api/hello.

检索

我应该如何调整文件才能找到 REST api？

更新

添加后

import restml.resources.hello import blueprint

我收到以下错误

Answer 1

您需要将 restml/resources/hello.py 文件导入 restml/__init__.py

from restml/resources/hello.py import blueprint

应该可以。
