一、在vue中引入外部的css文件

在项目的src文件下，新建一个style文件夹，存放css文件

1. 全局引入

将外部的css文件放到style文件下，引入外部文件只需在main.js文件中

```

import './style/reset.css'

```

我引入的是清除默认样式的css文件

2. 局部引入

```

@import '../assets/iconfont/iconfont.css';这个分号一定要写，要不会报错

```

二、.在uni-app 中应用的方法如下

```

@import url('../../static/style/common.css');

@import url('../../static/style/page.css');

import http from '../../common/http.js'

http.js 内容如下

let http = {

'setBaseUrl': (url) => {

if (url.charAt(url.length - 1) === "/") {

url = url.substr(0, url.length - 1)

}

http.baseUrl = url;

},

'header': {},

'beforeRequestFilter': (config) => { return config },

'beforeResponseFilter': (res) => { return res },

'afterResponseFilter': (successResult) => { },

'get': get,

'post': post,

'request': request,

'uploadFile': uploadFile,

'downloadFile': downloadFile,

'getgoodsList':getgoodsList,

}

function init(con) {

//url

let url = http.baseUrl;

if (url && con.url && !con.url.match(/^(http|https):\/\/([\w.]+\/?)\S*$/)) {

if (con.url.charAt(0) !== "/") {

con.url = "/" + con.url;

}

con.url = url.concat(con.url);

}

//header

if (http.header != undefined && http.header != null) {

if (!con.header) {

con.header = http.header;

} else {

Object.keys(http.header).forEach(function (key) {

con.header[key] = http.header[key]

});

}

}

}

function request(con) {

init(con);

let config = {

url: con.url ? con.url : http.baseUrl,

data: con.data,

header: con.header,

method: con.method ? con.method : 'GET',

dataType: con.dataType ? con.dataType : 'json',

responseType: con.responseType ? con.responseType : 'text',

success: con.success ? (res) => {

http.afterResponseFilter(con.success(http.beforeResponseFilter(res)));

} : null,

fail: con.fail ? (res) => {

con.fail(res);

} : null,

complete: con.complete ? (res) => {

con.complete(res);

} : null

}

return uni.request(http.beforeRequestFilter(config));

}

function get(url, con, success) {

let conf = {};

if (con && typeof con == 'function') {

if (success && typeof success == 'object') {

conf = success;

}

conf.success = con

}else{

if (con && typeof con == 'object') {

conf = con;

}

conf.success = success;

}

if (url) {

conf.url = url

}

conf.method = "GET";

return request(conf);

}

function post(url, data, con, success) {

let conf = {};

if (con && typeof con == 'function') {

if (success && typeof success == 'object') {

conf = success

}

conf.success = con;

} else {

if (con && typeof con == 'object') {

conf = con;

}

conf.success = success;

}

if (url) {

conf.url = url

}

if (data) {

conf.data = data

}

conf.method = "POST";

return request(conf);

}

function uploadFile(con) {

init(con);

let config = {

url: con.url ? con.url : http.baseUrl,

files: con.files,

filesType: con.filesType,

filePath: con.filePath,

name: con.name,

header: con.header,

formData: con.formData,

success: con.success ? (res) => {

http.afterResponseFilter(con.success(http.beforeResponseFilter(res)));

} : null,

fail: con.fail ? (res) => {

con.fail(res);

} : null,

complete: con.complete ? (res) => {

con.complete(res);

} : null

}

return uni.uploadFile(http.beforeRequestFilter(config));

}

function downloadFile(con) {

init(con);

let config = {

url: con.url ? con.url : http.baseUrl,

header: con.header,

success: con.success ? (res) => {

http.afterResponseFilter(con.success(http.beforeResponseFilter(res)));

} : null,

fail: con.fail ? (res) => {

con.fail(res);

} : null,

complete: con.complete ? (res) => {

con.complete(res);

} : null

}

return uni.downloadFile(http.beforeRequestFilter(config));

}

function getgoodsList(url){

console.log('sdsssdssssssssssssss')

return new Promise((resolve, reject) => {

uni.request({

url: url,

success: (res) => {

// store.commit('setAllClass', res.data);

// console.log(res.data.prolist)

resolve(res.data.prolist);

// resolve('suc');

},

fail: (err) => {

reject('err')

}

});

})

}

export default http

```
