# uni-app微信小程序----“起名”
|
||
|
||
## 第一章 uni-app入门
|
||
|
||
### 1-1 uni-app简介
|
||
|
||
|
||
|
||
### 1-2 小程序项目介绍
|
||
|
||
宝宝在线起名一直是中国人的刚需，与其路边寻找大师，不如求教线上业务
|
||
|
||
目前只在淘宝搜索：发现营业额极高，那就让我们把大师的价格打下去
|
||
|
||
|
||
|
||
|
||
|
||
### 1-3 uni-app安装及目录介绍
|
||
|
||
#### 下载hbuilderx
|
||
|
||
要讲UNI-APP,不得不介绍dcloud旗下一款轻量级ide编辑器hbuilderx
|
||
|
||
下载地址dcloud.io官网下载
|
||
|
||
hx mac和win之间分为标准和APP版
|
||
|
||
标准版需要自己安装插件，app开发版已经把app开发常用的插件预先集成，开箱即可用
|
||
|
||
#### UNI-APP有两种创建方式
|
||
|
||
使用 vue-cli 脚手架 创建 uni-app
|
||
|
||
| cli创建UNI-APP目录名称 | 解析 |
|
||
| ---------------------- | ------------------------------------------------------------ |
|
||
| dist ->build | 存放通过build编译的各个平台的代码，如mp-weixin |
|
||
| node_modules | 项目依赖包模块 |
|
||
| public | 放置的为公共文件，比如index.html文件，为项目的生成模板，我们写的vue的代码，在webpack打包项目的时候，最后都会基于该模板转换为浏览器可读的三大件：html+javascript+css |
|
||
| src | 存放通过HBuilderX可视化界面创建的的所有目录，为源码目录 |
|
||
| .gitignore | git上传需要忽略的文件格式 |
|
||
| babel.config.js | ES6语法编译配置 |
|
||
| package.json | 项目基本信息 |
|
||
| package-lock.json | 锁定安装时的包的版本号，并且需要上传到git，以保证其他人在npm install时大家的依赖能保证一致 |
|
||
| postcss.config.js | postcss-loader 的配置文件名，通过js对 CSS 进行处理 |
|
||
| README.md | 项目说明 |
|
||
|
||
|
||
|
||
| **pages** | 业务页面文件存放的目录 |
|
||
| ------------- | ------------------------------------------------------------ |
|
||
| **static** | 存放应用引用静态资源（如图片、视频等）的地方，注意：静态资源只能存放于此 |
|
||
| app.vue | 应用配置，用来配置App全局样式以及监听生命周期 |
|
||
| main.js | Vue初始化入口文件 |
|
||
| manifest.json | 配置应用名称、appid、logo、版本等打包信息 |
|
||
| pages.json | 配置页面路由、导航条、选项卡等页面类信息 |
|
||
| uni.scss | 全局样式 |
|
||
|
||
|
||
|
||
### 1-4 uni-app配置
|
||
|
||
|
||
|
||
uni-app配置项目目录和微信小程序的目录基本相同
|
||
|
||
mainfest.json
|
||
|
||
主要作用配置应用名称、appid、logo、版本等打包信息
|
||
|
||
appid是微信小程序身份唯一标识
|
||
|
||
appid，以微信小程序为例子，
|
||
|
||
进入公众平台
|
||
|
||
pages.json
|
||
|
||
配置页面路由、导航条、tabbar选项卡等页面类信息
|
||
|
||
当我们在微信小程序 json 中设置 backgroundColor 时，实际在电脑的模拟器中根本看不到效果,
|
||
|
||
窗体下拉刷新或上拉加载时露出的背景
|
||
|
||
|
||
|
||
## 第二章 整体设计
|
||
|
||
### 2.1api接口设计
|
||
|
||
#### 首先我们了解下
|
||
|
||
什么是前后端分离？
|
||
|
||
前后端分离，就是在对前端开发人员和后端开发人员的工作进行解耦，尽量减少他她们之间的交流成本，帮助他她们更能专注于自己擅长的工作。
|
||
|
||
前端web 框架 vue \react \angular
|
||
|
||
安卓端
|
||
|
||
ios端
|
||
|
||
小程序端
|
||
|
||
pwa
|
||
|
||
本项目是一款基于 SpringBoot 的 Api 服务器脚手架。服务端基础通用框架提取，配以详细的说明文档，针对 Restful 风格 API 服务器，降低学习成本，提高开发效率
|
||
|
||
#### API设计规范
|
||
|
||
设计接口是一件容易的事，也是件困难的事。设计接口每个人都会，每个人都能设计，也由此产生了各种各样的理念的接口。工作这么多年，我也很有感悟。很多人会说，设计接口多么简单，只要命名好，然后联调通了，上线可以调用就行了。特别是非互联网行业的人，这里没有歧视的意思。因为互联网行业和传统行业太多不一致性决定了这种思想的产生。
|
||
|
||
|
||
|
||
**通过不同的method（get\post\put\delete）来进行crud**
|
||
|
||
**格式{ "data": 返回数据, "code": 状态码, "msg": "返回描述"}**
|
||
|
||
### 2.2 mysql数据库搭建
|
||
|
||
本机vmware搭建centos7环境
|
||
|
||
使用docker安装mysql8
|
||
|
||
### 2.3 mysql数据库设计
|
||
|
||
客户端form表单
|
||
|
||
服务端算法推荐
|
||
|
||
## 第二章 前端页面
|
||
|
||
|
||
|
||
### 1.1 简介
|
||
|
||
前端使用uni-app
|
||
|
||
后端springboot2.X+mybatis plus
|
||
|
||
持久化数据库mysql8.0.16
|
||
|
||
效果展示:
|
||
|
||
|
||
|
||
### 1.2 微信小程序登录步骤
|
||
|
||
|
||
|
||
*第一步：小程序通过uni.login()获取code。*
|
||
|
||
*第二步：小程序通过uni.request()发送code到开发者服务器。*
|
||
|
||
*第三步：开发者服务器接收小程序发送的code，并携带appid、appsecret（这两个需要到微信小程序后台查看）、code发送到微信服务器。*
|
||
|
||
*第四步：微信服务器接收开发者服务器发送的appid、appsecret、code进行校验。校验通过后向开发者服务器发送session_key、openid。*
|
||
|
||
*第五步：开发者服务器自己生成一个key（自定义登录状态）与openid、session_key进行关联，并存到数据库中（mysql、redis等）。*
|
||
|
||
*第六步：开发者服务器返回生成key（自定义登录状态）到小程序。*
|
||
|
||
*第七步：小程序存储key（自定义登录状态）到本地。*
|
||
|
||
|
||
|
||

```
|
||
|
||
|
||
|
||
## 第二章 uni-app业务逻辑开发
|
||
|
||
### 2.1 vuex在uni-app中的使用
|
||
|
||
```
|
||
import Vue from 'vue'
|
||
import Vuex from 'vuex'
|
||
|
||
Vue.use(Vuex)
|
||
|
||
const store = new Vuex.Store({
|
||
state: {
|
||
hasLogin: false,
|
||
userInfo: {},
|
||
},
|
||
mutations: {
|
||
login(state, provider) {
|
||
|
||
state.hasLogin = true;
|
||
state.userInfo = provider;
|
||
uni.setStorage({//缓存用户登陆状态
|
||
key: 'userInfo',
|
||
data: provider
|
||
})
|
||
console.log(state.userInfo);
|
||
},
|
||
logout(state) {
|
||
state.hasLogin = false;
|
||
state.userInfo = {};
|
||
uni.removeStorage({
|
||
key: 'userInfo'
|
||
})
|
||
}
|
||
},
|
||
actions: {
|
||
|
||
}
|
||
|
||
})
|
||
|
||
export default store
|
||
```
|
||
|
||
|
||
|
||
### 2.2 登录功能实现
|
||
|
||
小程序已经抛弃getUserInfo,使用open-type绑定即可;
|
||
|
||
调用 wx.login 获取 code。
|
||
|
||
使用 wx.getSetting 获取用户的授权情况
|
||
|
||
- 如果用户已经授权，直接调用 API wx.getUserInfo 获取用户最新的信息；
|
||
- 用户未授权，在界面中显示一个按钮提示用户登入，当用户点击并授权后就获取到用户的最新信息。
|
||
|
||
将获取到的用户数据连同wx.login返回的code一同传给后端
|
||
|
||
|
||
|
||
|
||
|
||
## 第三章 数据库设计与运行
|
||
|
||
### 3.1 vmware使用docker安装mysql
|
||
|
||
**docker安装mysql,远程访问**
|
||
|
||
```text
|
||
//搜索mysql
|
||
docker search mysql
|
||
//选定版本，抓取镜像
|
||
docker pull mysql:8.0
|
||
//创建同步mysql的文件夹
|
||
mkdir -p /data/mysql01
|
||
//创建容器
|
||
docker run --name mysql01 -p 3307:3306 -v /data/mysql01:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=zan123456 -d mysql:8.0
|
||
|
||
|
||
--restart 标志会检查容器的退出代码，并据此来决定是否要重启容器，默认是不会重启。
|
||
--restart的参数说明
|
||
always：无论容器的退出代码是什么，Docker都会自动重启该容器。
|
||
on-failure：只有当容器的退出代码为非0值的时候才会自动重启。另外，该参数还接受一个可选的重启次数参数，`--restart=on-fialure:5`表示当容器退出代码为非0时，Docker会尝试自动重启该容器，最多5次。
|
||
|
||
-v 容器内的 /var/lib/mysql 在宿主机上 /data/mysql01 做映射
|
||
-e MYSQL_ROOT_PASSWORD 初始密码
|
||
-p 将宿主机3306的端口映射到容器3306端口
|
||
```
|
||
|
||
**error:如果启动失败，查看日志docker logs mysql01提示**
|
||
|
||
chown: cannot read directory '/var/lib/mysql/': Permission denied
|
||
|
||
容器中没有执行权限 //挂载外部数据卷时,无法启动容器, 报 chown: cannot read directory '/var/lib/mysql/': Permission denied 由$ docker logs [name] 查看得知 该原因为centOs7默认开启selinux安全模块,需要临时关闭该安全模块,或者添加目录到白名单 临时关闭selinux：su -c "setenforce 0" 重新开启selinux：su -c "setenforce 1" 添加selinux规则，将要挂载的目录添加到白名单： 示例：chcon -Rt svirt_sandbox_file_t /data/mysql01(我启动挂载的路径)
|
||
|
||
|
||
|
||
**error:用navicat连接如果报错**
|
||
|
||
报错是因为加密算法变了
|
||
|
||
我们在docker里面改变加密算法
|
||
|
||
```text
|
||
mysql> grant all PRIVILEGES on *.* to root@'%' WITH GRANT OPTION;
|
||
Query OK, 0 rows affected (0.01 sec)
|
||
|
||
mysql> ALTER user 'root'@'%' IDENTIFIED BY '123456' PASSWORD EXPIRE NEVER;
|
||
Query OK, 0 rows affected (0.11 sec)
|
||
|
||
mysql> ALTER user 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
|
||
Query OK, 0 rows affected (0.11 sec)
|
||
|
||
mysql> FLUSH PRIVILEGES;
|
||
Query OK, 0 rows affected (0.01 sec)
|
||
```
|
||
|
||
算法换成mysql_native_password即可
|
||
|
||
### 3.2 user数据表建立
|
||
|
||
配置application.yml
|
||
|
||
```
|
||
server:
|
||
port: 8080
|
||
spring:
|
||
datasource:
|
||
url: jdbc:mysql://192.168.253.133:3307/test?useUnicode=true&useSSL=false&characterEndcoding=utf8&useTimezone=true&serverTimezone=Asia/Shanghai
|
||
username: root
|
||
password: 123456
|
||
driver-class-name: com.mysql.cj.jdbc.Driver
|
||
```
|
||
|
||
创建表格
|
||
|
||
```
|
||
CREATE TABLE `user` (
|
||
`open_id` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NOT NULL COMMENT 'open_id',
|
||
`skey` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NOT NULL COMMENT 'skey',
|
||
`create_time` timestamp(0) NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
|
||
`last_visit_time` timestamp(0) NULL DEFAULT CURRENT_TIMESTAMP COMMENT '最后登录时间',
|
||
`session_key` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NOT NULL COMMENT 'session_key',
|
||
`avatar_url` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '头像',
|
||
`nick_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '网名',
|
||
PRIMARY KEY (`open_id`) USING BTREE
|
||
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '微信用户信息' ;
|
||
```
|
||
|
||
|
||
|
||
## 第四章 springboot开发后端接口
|
||
|

```
|

### 4.3 common封装工具类
|
