mpvue 小程序项目初始化流程随手记

初始化 mpvue 项目

---

# 全局安装 vue-cli
$ npm install --global vue-cli

# 创建一个基于 mpvue-quickstart 模板的新项目
$ vue init mpvue/mpvue-quickstart my-project

# 安装依赖
$ cd my-project
$ npm install
# 启动构建
$ npm run dev

使用 vuex-persistedstate 防止数据丢失

---

安装：

npm install vuex-persistedstate

配置：

// 根据目录结构在store下的index.js文件下引入如下代码

import Vue from 'vue';
import Vuex from 'vuex'
import createPersistedState from 'vuex-persistedstate'

Vue.use(Vuex)
const store = new Vuex.Store({
    state: {
        girlName: "",
        boyName: ""
    },
    mutations: {
        update(state, config) {
            Object.keys(config).map((item, key) => {
                state[item] = config[item]
            })
        }
    },
    plugins: [
        createPersistedState({
            storage: {
                getItem: key => wx.getStorageSync(key),
                setItem: (key, value) => wx.setStorageSync(key, value),
                removeItem: key => () => { }
            }
        })
    ]
})
export default store

用法（获取值和设置值）：

// 在 .vue 文件中使用

<script>
import { mapState, mapMutations } from "vuex";
export default {
  computed: {
    ...mapState(["girlName", "boyName"])
  },
 },
 methods: {
    ...mapMutations(["update"]),
    updateBoyName(newBoyName) {
      this.update({
        boyName: newBoyName
      });
    },
  },

安装 animate.css 动画库

---

安装：

npm install animate.css --save

配置：

// scr/main.js 下加上如下配置
import animated from 'animate.css' // npm install animate.css --save安装，在引入
 
Vue.use(animated)

用法：

<div  :class="isShow? 'animated zoomIn faster' :'animated zoomOut faster'">
</div>

让小程序支持 scss 语法

---

 npm i sass-loader -D 
 npm i node-sass -D

安装完毕直接可以使用:

<style lang="scss" scoped>

</style>

使用 Mpvue-WeUI 让程序能使用小程序自带的 UI 控件

---

文档：
https://mpcomponent.github.io/mpvue-weui
安装：

npm install mpvue-weui

配置：

/* 全局引入 weui.css (在 `src/main.js` 中引入 weui.css) */
import 'mpvue-weui/src/style/weui.css';

用法：

<template>
  <mp-button type="primary" size="large" btnClass="mb15">默认按钮</mp-button>
</template>
<script>
  import mpButton from 'mpvue-weui/src/button';
  export default {
    components: {
      mpButton,
    },
  }
</script>

初步封装小程序的网络请求模块

---

配置第一步：

// 在 utils 目录下，创建 wx-request.js 写入如下内容

const host = 'https://xxxx.com'
 
function request (url, method, data, header = {}) {
  wx.showLoading({
    title: '加载中' // 数据请求前loading
  })
  return new Promise((resolve, reject) => {
    wx.request({
      url: host + url, // 仅为示例，并非真实的接口地址
      method: method,
      data: data,
      headers: {
        'content-type': 'application/json' // 默认值
      },
      success: function (res) {
        wx.hideLoading()
        resolve(res.data)
      },
      fail: function (res) {
        wx.hideLoading()
        console.log('request fail');
        reject(false)
      },
      complete: function () {
        wx.hideLoading()
        console.log('request complete');
      }
    })
  })
}
 
function get (obj) {
  return request(obj.url, 'GET', obj.data)
}
 
function post (obj) {
  return request(obj.url, 'POST', obj.data)
}
 
export default {
  request,
  get,
  post,
  host
}

配置第二步：

// 在 src/mian.js 中加入如下配置
import WXrequest from './utils/wx-request'
Vue.prototype.$httpWX = WXrequest

用法：

    this.$httpWX
        .get({
          url: "/msgCheck",
          data: {
            content: tempString
          }
        })
        .then(res => {
          if (res.errcode == 87014) {
            this.tipContent = "内容包含敏感词,请及时修改";
            setTimeout(() => {
              this.$refs.mpModal.show();
            });
          } else {
            let url = "/pages/turnTableGame/main";
            mpvue.navigateTo({ url });
          }
        }).catch(resaon => {
            let url = "/pages/turnTableGame/main";
            mpvue.navigateTo({ url });
        });
