我正在使用flask-restful进行一项宁静的服务,我想在我的项目中利用工厂模式和蓝图.在app/__init__.py我有一个create_app函数来创建一个烧瓶应用程序,并返回给外线来电,所以调用者可以启动应用程序.
def create_app():
app = Flask(__name__)
app.config.from_object('app.appconfig.DevelopmentConfig')
from app.resource import resource
app.register_blueprint(v1, url_prefix='/api')
print app.url_map
return app
在该函数内部,我打算使用前缀url注册指向实现包的蓝图.
在app/resource/__init__.py下面是代码
from flask import current_app, Blueprint, render_template
from flask.ext import restful
resource = Blueprint('resource', __name__, url_prefix='/api')
@resource.route('/')
def index():
api = restful.Api(current_app)
from resource.HelloWorld import HelloWorld
api.add_resource(HelloWorld, '/hello')
我的目标是我可以在url访问HelloWorld休息服务/api/hello,但我知道上面的代码有些错误@resource.route('/') ....我得到了一些错误,如AssertionError: A setup function was called after the first request was handled. This usually indicates a bug in the app ...在 …
以下是来自flask-restful doc的示例代码
from flask import Flask
from flask.ext import restful
app = Flask(__name__)
api = restful.Api(app)
class HelloWorld(restful.Resource):
def get(self):
return {'hello': 'world'}
api.add_resource(HelloWorld, '/')
if __name__ == '__main__':
app.run(debug=True)
这个HelloWorld类在同一个python文件中,比方说app.py,它有效.
现在我将把HelloWorld类放到一个单独的类文件中,如下面的布局:
app
app/__init__.py # hold above code except the HelloWorld class.
app/resource
app/resource/__init__.py # empty
app/resource/HelloWorld.py # hold the above HelloWorld class.
该app/__init__.py包含:
from flask import Flask
from flask.ext import restful
from resource.HelloWorld import HelloWorld
app = Flask(__name__)
api …
