[英]Flask-RESTful alias
I would like to create an alias between two resources. 我想在两个资源之间创建一个别名。
from flask import Flask
from flask_restful import Api, Resource
class api_v1_help(Resource):
def get(self):
html_file = "API V1"
return (html_file, 200, {'Content-Type': 'text/html; charset=utf-8'})
class api_v2_help(Resource):
def get(self):
html_file = "API V2"
return (html_file, 200, {'Content-Type': 'text/html; charset=utf-8'})
app = Flask(__name__)
api = Api(app)
# API (current)
api.add_resource(api_v1_help, '/api/help')
# API v1
api.add_resource(api_v1_help, '/api/v1/help')
# API v2
api.add_resource(api_v2_help, '/api/v2/help')
if __name__ == '__main__':
# Start app
app.run(debug=True,port=5000)
This is giving the following error : AssertionError: View function mapping is overwriting an existing endpoint function: api_v1_help 这将产生以下错误:AssertionError:视图函数映射正在覆盖现有的终结点函数:api_v1_help
I can change the code like this : 我可以这样更改代码:
api.add_resource(api_v1_help, '/api/help', '/api/v1/help')
but I would like to know if there is another solution with flask-restful to handle an alias by linking two API endpoints to the same function? 但我想知道是否存在通过将两个API端点链接到同一函数来解决烧瓶问题的另一种解决方案?
I search to group the calls for a specific API version. 我搜索将特定API版本的调用分组。
Use Flask.add_url_route
instead: 改用
Flask.add_url_route
:
# API v1
api.add_resource(api_v1_help, '/api/v1/help')
# API v2
api.add_resource(api_v2_help, '/api/v2/help')
# API (current)
app.add_url_rule('/api/help', endpoint='api_v1_help')
By default, endpoint
is set as the name of the view class , so you can use 'api_v1_help'
as the name after the add_resource
call. 默认情况下,将
endpoint
设置为视图类的名称 ,因此可以在add_resource
调用之后使用'api_v1_help'
作为名称。
