1.5 报错
09:47:36 [vite] hmr update /src/views/tb/drug/index.vue
Failed to load url /src/utils/request (resolved id: C:/Users/lxz/Desktop/project/drug-system/ruoyi-vue-pro-drug/yudao-ui-admin-vue3/src/utils/request) in C:/Users/lxz/Desktop/project/drug-system/ruoyi-vue-pro-drug/yudao-ui-admin-vue3/src/api/test.js. Does the file exist?
问题:在 更新的/src/views/tb/drug/index.vue 文件中,没有找到 /src/utils/request 这个文件
解决办法: 从vue2项目中将/src/utils/request.js 这个文件复制到vue3项目的对应文件夹下
1.6 报错

这个是vue2项目中直接引入使用的外部axios依赖
"dependencies": {
"@babel/parser": "7.18.4",
"@riophae/vue-treeselect": "0.4.0",
"axios": "0.27.2",
...
在vue3项目中没有直接使用这个依赖,而是对axios进行了扩展
"dependencies": {
"@element-plus/icons-vue": "^2.1.0",
"@form-create/designer": "^3.1.3",
"@form-create/element-ui": "^3.1.24",
"@iconify/iconify": "^3.1.1",
"@videojs-player/vue": "^1.0.0",
"@vueuse/core": "^10.6.1",
"@wangeditor/editor": "^5.1.23",
"@wangeditor/editor-for-vue": "^5.1.10",
"@zxcvbn-ts/core": "^3.0.4",
"animate.css": "^4.1.1",
"axios": "^1.6.1",
vue3项目中的axios封装链:
从vue3项目的src/system/area/index.ts文件中封装的request对象进行向底层追溯
import request from '@/config/axios'
// 获得地区树
export const getAreaTree = async () => {
return await request.get({ url: '/system/area/tree' })
}
// 获得 IP 对应的地区名
export const getAreaByIp = async (ip: string) => {
return await request.get({ url: '/system/area/get-by-ip?ip=' + ip })
}
进入 src/config/axios/index.ts文件中
import { service } from './service'
import { config } from './config'
const { default_headers } = config
const request = (option: any) => {
const { url, method, params, data, headersType, responseType, ...config } = option
return service({
url: url,
method,
params,
data,
...config,
responseType: responseType,
headers: {
'Content-Type': headersType || default_headers
}
})
}
export default {
get: async <T = any>(option: any) => {
const res = await request({ method: 'GET', ...option })
return res.data as unknown as T
},
post: async <T = any>(option: any) => {
const res = await request({ method: 'POST', ...option })
return res.data as unknown as T
},
postOriginal: async (option: any) => {
const res = await request({ method: 'POST', ...option })
return res
},
delete: async <T = any>(option: any) => {
const res = await request({ method: 'DELETE', ...option })
return res.data as unknown as T
},
put: async <T = any>(option: any) => {
const res = await request({ method: 'PUT', ...option })
return res.data as unknown as T
},
download: async <T = any>(option: any) => {
const res = await request({ method: 'GET', responseType: 'blob', ...option })
return res as unknown as Promise<T>
},
upload: async <T = any>(option: any) => {
option.headersType = 'multipart/form-data'
const res = await request({ method: 'POST', ...option })
return res as unknown as Promise<T>
}
}
封装http请求对象,并导出get、post、postOriginal、delete、put、download、upload等公共方法
进入 ./config文件中
const config: {
base_url: string
result_code: number | string
default_headers: AxiosHeaders
request_timeout: number
} = {
/**
* api请求基础路径
*/
base_url: import.meta.env.VITE_BASE_URL + import.meta.env.VITE_API_URL,
/**
* 接口成功返回状态码
*/
result_code: 200,
/**
* 接口请求超时时间
*/
request_timeout: 30000,
/**
* 默认接口请求类型
* 可选值:application/x-www-form-urlencoded multipart/form-data
*/
default_headers: 'application/json'
}
export { config }
封装了http请求的请求基础路径、返回结果状态码、请求头、请求超时时间等配置信息
进入./service文件中
import axios, {
AxiosError,
AxiosInstance,
AxiosRequestHeaders,
AxiosResponse,
InternalAxiosRequestConfig
} from 'axios'
在这里可以看到vue2项目中使用的axios对象,此时,vue3项目中使用的axios版本和vue2项目中使用的版本不一致可能会存在隐患
此处引用了element-ui的依赖,在vue3项目中已经弃用了element-ui而是采用Element Plus
vue3项目中的依赖
"element-plus": "2.4.2",
vue2项目中依赖
"element-ui": "2.15.12",
需要对vue2项目中的request.js中使用的element-ui进行改造成element-plus中的组件!
import store from ‘@/store’
在vue2项目中使用的vuex来做状态管理的,在vue3项目中是没有引入vuex依赖的
在vue3项目中使用了vue-demi来解决这个问题吗,那么我们在保证vue-demi可用的前提下可以不用考虑这个问题!
import {getAccessToken, getRefreshToken, getTenantId, setToken} from ‘@/utils/auth’
这个在vue3项目中已经兼容了并且做了局部功能升级,在vue2版本的项目中没有对AccessTokenKey,RefreshTokenKey加入到浏览器本地存储中,在vue3项目中引入了web-storage-cache来做本地存储
"web-storage-cache": "^1.1.1",
// import request from '@/utils/request'
// 这个是vue3项目中使用.ts文件封装的http请求对象
import request from '@/config/axios'
// 创建药品
export function create(data) {
return request({
url: '/drug//create',
method: 'post',
data: data
})
}
// 获得地区树 这个是ts文件封装的http请求对象的使用方法
export const getAreaTree = async () => {
return await request.get({ url: '/system/area/tree' })
}
这个文件是src\api\test.js
