flask接收post提交的json数据并保存至数据库

定义数据模型

# 定义数据模型
class User(db.Model):

    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(20), nullable=False, unique=True)
    phone = db.Column(db.Integer, nullable=False)

    def __repr__(self):
        return '<User {}>'.format(self.name)

请求路由

# 请求路由
@app.route('/user', methods=['GET', 'POST'])
def userinfo():
    users = User.query.all()
    if request.method == 'POST':
        name = request.json.get('name')
        phone = request.json.get('phone')
        user = User(
            name=name,
            phone=phone
        )
        if User.query.filter_by(name=name).first():
            return jsonify({"msg": "name already in use"})
        try:
            db.session.add(user)
            db.session.commit()
        except:
            return jsonify({"msg": "error"})
        return jsonify({'msg': 'ok'})

    user_list = []
    for user in users:
        data = {}
        data['id'] = user.id
        data['name'] = user.name
        data['phone'] = user.phone
        user_list.append(data)
    return jsonify({"users": user_list})

POST请求结果如下
