如何使用blueprints和restfull访问flask中的post数据

Question

我到底如何使用blueprints和flask-restfull从flask应用程序中获取post数据？为什么这么难？

在views.py文件中

 api.add_resource(register, '/api/driver/register')

我的资源文件中：

from flask_restful import fields, marshal_with, reqparse, Resource
class register(Resource):
    def post(self):
        ACCESS MY POST DATA!!!!!!!!!!!!!
        return 'omg' 



curl -H "Content-Type: application/json" -X POST -d '{"f":"xyz","u":"xyz"}' http://0.0.0.0:5000/api/driver/register

Answer 1

以下是您的示例的改编。根据您的导入，看起来您走上了正确的道路。我的示例只接受2个JSON参数，即email和mobile，并以JSON格式回显它们。您可以使用args['email']和args['mobile']引用处理和业务逻辑的值。

from flask_restful import fields, marshal_with, reqparse, Resource
class register(Resource):
    def post(self):
        reqparse = reqparse.RequestParser()
        reqparse.add_argument('email', type=str)
        reqparse.add_argument('mobile', type=int)
        args = reqparse.parse_args()
        response = {'email': args['email'], 'mobile': args['mobile']}
        response_fields = {'email': fields.String, 'mobile': fields.Integer}
        return marshal(response, response_fields), 200

Answer 2

这就是我要做的。

from flask_restful import fields, marshal_with, reqparse, Resource


class Register(Resource):

    def __init__(self):
        self.reqparse = reqparse.RequestParser()
        self.reqparse.add_argument('field_data_one', type=str, required=True, location='json')
        self.reqparse.add_argument('field_data_two', type=str, required=True, location='json')
        ...

    def post(self):
        args = self.reqparse.parse_args()

        obj = {
            'field_data_one': args['field_data_one'],
            'field_data_two': args['field_data_two']
        }

        return {'omg': obj}, 201

        # ACCESS MY POST DATA!!!!!!!!!!!!!
        # return 'omg'
