使用HBuilder+MUI+Flask后端服务器框架+Mongodb数据库开发手机APP

1.开发准备HBuilder:

1.下载安装HBuilder
2.创建APP项目
3.代码示例:

注册HTML

 写前端代码可以参考mui官网文档:http://dev.dcloud.net.cn/mui

2.后端代码:

1.MongoDB数据库准备
参考:https://www.cnblogs.com/changtao/p/10609908.html
2.Python中配置MongoDB
示例代码
import pymongo
conn = pymongo.MongoClient('127.0.0.1',27017)
MONGODB = conn["tuling"]  # tuling 是数据库的名字
mongodb
from flask import Flask, request, render_template, redirect, jsonify,send_file
from db import MONGODB


app = Flask(__name__)

@app.route('/login',methods=['POST'])
def login():
    username = request.form.get('username')
    pwd = request.form.get('pwd')
    ret = list(MONGODB.user.find({"name":username},{'_id':0}))
    if pwd == ret[0].get('pwd'):
        return jsonify({"msg":"登陆成功","erromsg":None})
    else:
        return jsonify({'msg':"登陆失败","erromsg":',密码输入错误'})

@app.route('/sigin',methods=['POST'])
def sigin():
    username = request.form.get('username')
    pwd = request.form.get('pwd')
    re_pwd = request.form.get('repwd')
    if pwd == re_pwd:
        MONGODB.user.insert_one({'name':username,'pwd':re_pwd})
        return jsonify({"msg":"注册成功","errormsg":None})
    else:
        return jsonify({"msg": "注册失败", "errormsg": '两次密码输入的不一样'})


@app.route('/img1')
def img1():
    return send_file('.staticimgimg1.png')

@app.route('/img2')
def img2():
    return send_file('.staticimgimg2.png')

@app.route('/img3')
def img3():
    return send_file('.staticimgimg3.png')

@app.route('/img4')
def img4():
    return send_file('.staticimgimg4.png')



if __name__ == '__main__':
    app.run('0.0.0.0',8600)
Python 逻辑代码

3.在模拟器上运行:

修改端口.

之后点击运行即可

4.在真机上运行,

1.确保手机USB调试打开,下载一个应用宝,能连接上手机即可
2.运行即可
3.手机和电脑需在同一个局域网内,方可连上服务器
