VUE采用VW布局结合vant UI搭建项目流程

VUE采用VW布局结合vant UI搭建项目流程

  1. 默认本地安装好了node环境及v-cli脚手架(未安装的话请行安装),检查版本。

  1. 代码编辑器(webStorm)打开项目文件夹,键入命令:

        vue init webpack Management

  1. 根据命令提示做相应的操作:

4.接下来安装vw布局需要的插件,在.postcssrc.js文件中Vue-cli默认配置了三个PostCSS插件

我们还需要安装以下六个插件:

postcss-aspect-ratio-mini

postcss-px-to-viewport
postcss-write-svg
postcss-cssnext
postcss-viewport-units
cssnano

键入命令:

npm i postcss-aspect-ratio-mini postcss-px-to-viewport postcss-write-svg postcss-cssnext postcss-viewport-units cssnano –S

安装完成后在package.json中会看到如下配置:

5.接下来在.postcssrc.js文件对新安装的PostCSS插件进行配置: (注意红框中的内容)

6.安装sass(项目用sass预编译语言,采用vant UI)

npm i node-sass  --save    npm i sass-loader  --save

安装完成在package.json配置清单可以查看对应项及版本号

7.引入vant (不作赘述,按照官方文档操作,建议采用按需引入的方式)

8.修改config文件

9.统一处理axios请求,处理请求拦截和响应拦截(http.js文件)

var root = "/api";

import axios from "axios";

import qs from "qs";

import { Toast } from "vant";

import { clearStorage } from './clear'

import router from "../router";



import { Loading } from 'vant';

// axios 配置

axios.defaults.timeout = 50000;

axios.defaults.baseURL = root;

axios.defaults.withCredentials = true;

var num=0;

// http request 拦截器

axios.interceptors.request.use(

    config => {

        num++;

        if( num === 1 ){

            window['getHref'] = val => {

                regist(val);

            }

            // buffer_tip_show();

        };

        if (config.method == "post" && config.url.indexOf("/upload/img") <= 0) {

            config.data.lang_id = config.data.lang_id || localStorage.getItem("lang_id");

            if (localStorage.getItem("token")) {

                config.data.token = localStorage.getItem("token");

            }

            if (localStorage.getItem("keyid")) {

                config.data.keyid = localStorage.getItem("keyid");

            }

            config.data = qs.stringify(config.data);

        }

        if (config.method == "post" && config.url.indexOf("/upload/img") > 0) {

            config.headers = {

                Accept: "application/json, text/javascript, */*",

                "Content-Type": "multipart/form-data; boundary=----WebKitFormBoundaryhwvBOffcBtcVGV8f"

            };

        } else {

            config.headers = {

                Accept: "application/json, text/javascript, */*",

                "Content-Type": "application/x-www-form-urlencoded;charset=UTF-8"

            };

        }

        return config;

    },

    err => {

        return Promise.reject(err);

    }

);



// http response 拦截器

axios.interceptors.response.use(

    response => {

        num--;

        if( num === 0 ){

            // buffer_tip_hidden();

        };

        //请先登录

        if (response.data.status == 0) {

            // 错误

            Toast(response.data.msg);

        }

        else if (response.data.status == 2) {

            //请重新登录

            let instance = Toast(response.data.msg);

            // 清除Session

            clearStorage();

            setTimeout(() => {

                instance.close();

                router.push("/login");

            }, 1000);

        }

        // else if (response.data.status == 3) {

        //     let instance = Toast(response.data.msg);

        //     setTimeout(() => {

        //         instance.close();

        //         router.push("/security_code");

        //     }, 2000);

        // }

        return response;

    },

    error => {

        num--;

        if( num === 0 ){

            // buffer_tip_hidden();

        };

        //请先登录

        if (error.response.data.status == 2) {

            //请重新登录

            let instance = Toast(response.data.msg);

            // 清除Session

            clearStorage();

            setTimeout(() => {

                instance.close();

                router.push("/login");

            }, 1000);

            return false;

        }

        return Promise.reject(error.response.data);

    }

);
