Flask 学习-40.Flask-RESTful 结合蓝图使用

前言

Flask-RESTful 结合蓝图使用设计接口

RESTful 接口

没使用蓝图之前 注册接口

from apps import create_app, db, jwt
from flask import url_for, request, jsonify
from flask_restful import reqparse, abort, Api, Resource
from apps.models import Users
app = create_app()
api = Api(app)


class Register(Resource):

    @staticmethod
    def password_validate(value, name):
        if len(value) < 6 or len(value) > 16:
            raise ValueError(name + ' length must be 6-16')
        return value

    def post(self):
        # 校验入参
        parser = reqparse.RequestParser()
        parser.add_argument('username', required=True, type=str,  nullable=False)
        parser.add_argument('password', required=True, type=self.password_validate,
                            nullable=False, help='invalid: error_msg')
        args = parser.parse_args()

        print(f'请求入参：args')

        return jsonify(
            "code": 0,
            "msg": "success"
        )


# 注册
api.add_resource(Register, '/api/v1/register')

使用 蓝图

蓝图的项目结构设计参考这篇https://www.cnblogs.com/yoyoketang/p/16624854.html

D:\\demo\\xuexi_flask

│   ├── __init__.py
│   ├── auth.py
│   ├── blog.py
│   ├── pay.py

那么可以在auth.py 写注册相关的接口

from flask import (
    Blueprint, flash, g, redirect, render_template, request, session, url_for
)
from flask_restful import Api, reqparse, abort, Api, Resource


bp = Blueprint('auth', __name__, url_prefix='/auth')
api = Api(bp)


class Register(Resource):

    @staticmethod
    def password_validate(value, name):
        if len(value) < 6 or len(value) > 16:
            raise ValueError(name + ' length must be 6-16')
        return value

    def post(self):
        # 校验入参
        parser = reqparse.RequestParser()
        parser.add_argument('username', required=True, type=str,  nullable=False)
        parser.add_argument('password', required=True, type=self.password_validate,
                            nullable=False, help='invalid: error_msg')
        args = parser.parse_args()
        print(f'请求入参：args')
        return 
            "code": 0,
            "msg": "success"
        


# 注册
api.add_resource(Register, '/api/register')

测试接口

POST http://127.0.0.1:5000/auth/api/register HTTP/1.1
User-Agent: Fiddler
Host: 127.0.0.1:5000
Content-Type: application/json
Content-Length: 56


    "username": "test",
    "password" : "123456"

接口返回

Date: Fri, 02 Sep 2022 07:25:39 GMT

Connection: close


    "code": 0,
    "msg": "success"
