一、玩具管理页面

点击下面的标签，页面还没有反应。

点击之后，需要进入玩具管理页面！

进入HBuilder项目MyApp，新建文件toy_info.html

修改 toy_info.html

进入flask后端，修改 serv-->toys.py，增加接口

from flask import Blueprint, request, jsonify
from setting import MONGO_DB
from setting import RET
from bson import ObjectId

toy = Blueprint("toy", __name__)


@toy.route("/toy_list", methods=["POST"])
def toy_list():  # 玩具列表
    user_id = request.form.get("user_id")  # 用户id
    # 查看用户信息
    user_info = MONGO_DB.users.find_one({"_id": ObjectId(user_id)})
    bind_toy = user_info.get("bind_toy")  # 获取绑定的玩具
    bind_toy_id = []  # 玩具列表
    for toy_id in bind_toy:  # 获取玩具列表中的所有玩具id
        bind_toy_id.append(ObjectId(toy_id))

    # 一次性查询多个玩具

    for index,item in enumerate(toys_list):
        # 将_id转换为字符串
        toys_list[index]["_id"] = str(item.get("_id"))

    RET["code"] = 0
    RET["msg"] = ""
    RET["data"] = toys_list

    return jsonify(RET)


@toy.route("/device_toy_id", methods=["POST"])
def device_toy_id():  # 验证设备id
    RET["code"] = 0
    RET["msg"] = "开机成功"
    RET["data"] = {}

    device_id = request.form.get("device_id")  # 获取设备id

会发现，小甜甜和小豆芽，互为好友了！

今日总结：

1.玩具管理页面
    mui组件 ：
        msl  : 图文表格


2.控制玩具通讯录
    

3.基于请求的好友关系建立
    发送请求：带上自己的所有信息 + 请求信息
    接收请求：可以看到自己的所有消息
    双方添加好友：
    同意：
        1.判断自己是玩具还是用户
        2.查询好友的信息
        3.建立好友的信息（friend_list 中的元素）
        4.将建立的好友信息存放在自己的friend_list中
        5.建立自己的信息（好友的friend_list 中的元素）
        6.将建立的自己信息存放在好友的friend_list中
        7.将请求的状态改为 1
