首先安装依赖：

pip install flask_siwadoc pydantic

封装swagger.py文件，代码如下：

from flask_siwadoc import SiwaDoc
siwa = SiwaDoc()

然后在主应用中（项目入口文件）加入以下代码：

from flask import Flask
from swagger import siwa #导入它
app = Flask(__name__)
siwa.init_app(app)

在user.py中加入以下代码：

from flask import Blueprint,request, session
from swagger import siwa #导入它
from pydantic import BaseModel, Field
user_bp = Blueprint('user', __name__, url_prefix='/user')
class loginModel(BaseModel):username:str=Field(...)password:str=Field(...)
@user_bp.route('/login', methods=['POST'])
@siwa.doc(body=loginModel,tags=["user"])
def user_login(body:loginModel):reqJSONData = request.get_json(silent=True)print(reqJSONData)if not reqJSONData: return r(code=401, msg='登录失败, 请求参数为空')username = reqJSONData.get('username')password = reqJSONData.get('password')if not all([username, password]):return r(code=401, msg='登录, 缺少请求参数')user = supabase.table('sys_user').select('id,username,name').eq('username',username).eq('password',password).execute().data# 4. 用户不存在, 直接返回if not user:return r(code=404, msg='用户名或密码错误')else:access_token = create_access_token(identity=user[0])session['user_info'] = userreturn r(msg='登录成功', data={"token":access_token})
