目前，關於vue中使用axios的作為前端和後端介面互動工具的用法文章，網路某部落格上數不勝數。因為專案從0到1開始需要基於vite vue3.0 ts中封裝axios，所以今天請小編來為大家安排axios整合vite vue3.0 ts的具體封裝步驟。記錄自己封裝步驟，跟著我的步伐，擼起來。 。 。 （學習影片分享：vue影片教學）
以下內容皆基於下方影片完結後的擴充功能：
npm i axios
注意：這裡的安裝指令就是預設安裝最新版本的axios
export const errorCodeType = function(code:string):string{
let errMessage:string = "未知错误"
switch (code) {
case 400:
errMessage = '错误的请求'
break
case 401:
errMessage = '未授权，请重新登录'
break
case 403:
errMessage = '拒绝访问'
break
case 404:
errMessage = '请求错误,未找到该资源'
break
case 405:
errMessage = '请求方法未允许'
break
case 408:
errMessage = '请求超时'
break
case 500:
errMessage = '服务器端出错'
break
case 501:
errMessage = '网络未实现'
break
case 502:
errMessage = '网络错误'
break
case 503:
errMessage = '服务不可用'
break
case 504:
errMessage = '网络超时'
break
case 505:
errMessage = 'http版本不支持该请求'
break
default:
errMessage = `其他连接错误 --${code}`
}
return errMessage
}這裡用到的element-plus大家可以參考其官網安裝即可，傳送門：
安装命令： npm install element-plus --save
import axios from 'axios';
import { errorCodeType } from '@/script/utils/error-code-type';
import { ElMessage, ElLoading } from 'element-plus';
// 创建axios实例
const service = axios.create({
// 服务接口请求
baseURL: import.meta.env.VITE_APP_BASE_API,
// 超时设置
// timeout: 15000,
headers:{'Content-Type':'application/json;charset=utf-8'}
})
let loading:any;
//正在请求的数量
let requestCount:number = 0
//显示loading
const showLoading = () => {
if (requestCount === 0 && !loading) {
//加载中显示样式可以自行修改
loading = ElLoading.service({
text: "拼命加载中，请稍后...",
background: 'rgba(0, 0, 0, 0.7)',
spinner: 'el-icon-loading',
})
}
requestCount++;
}
//隐藏loading
const hideLoading = () => {
requestCount--
if (requestCount == 0) {
loading.close()
}
}
// 请求拦截
service.interceptors.request.use(config => {
showLoading()
// 是否需要设置 token放在请求头
// config.headers['Authorization'] = 'Bearer ' + getToken() // 让每个请求携带自定义token 请根据实际情况自行修改
// get请求映射params参数
if (config.method === 'get' && config.params) {
let url = config.url + '?';
for (const propName of Object.keys(config.params)) {
const value = config.params[propName];
var part = encodeURIComponent(propName) + "=";
if (value !== null && typeof(value) !== "undefined") {
// 对象处理
if (typeof value === 'object') {
for (const key of Object.keys(value)) {
let params = propName + '[' + key + ']';
var subPart = encodeURIComponent(params) + "=";
url += subPart + encodeURIComponent(value[key]) + "&";
}
} else {
url += part + encodeURIComponent(value) + "&";
}
}
}
url = url.slice(0, -1);
config.params = {};
config.url = url;
}
return config
}, error => {
console.log(error)
Promise.reject(error)
})
// 响应拦截器
service.interceptors.response.use((res:any) => {
hideLoading()
// 未设置状态码则默认成功状态
const code = res.data['code'] || 200;
// 获取错误信息
const msg = errorCodeType(code) || res.data['msg'] || errorCodeType('default')
if(code === 200){
return Promise.resolve(res.data)
}else{
ElMessage.error(msg)
return Promise.reject(res.data)
}
},
error => {
console.log('err' + error)
hideLoading()
let { message } = error;
if (message == "Network Error") {
message = "后端接口连接异常";
}
else if (message.includes("timeout")) {
message = "系统接口请求超时";
}
else if (message.includes("Request failed with status code")) {
message = "系统接口" + message.substr(message.length - 3) + "异常";
}
ElMessage.error({
message: message,
duration: 5 * 1000
})
return Promise.reject(error)
}
)
