vue中请求接口

request.ts

import axios, {AxiosInstance, AxiosError, AxiosResponse, AxiosRequestConfig} from 'axios';
 
const env = import.meta.env
 
const toLogin=()=>{
    window.location.href="/login"
}
 
const toError=()=>{
    window.location.href="/404"
}
 
let baseURL=""
 
switch(env.MODE){
    case 'development':
        baseURL='/api';
    break;
    case 'test':
        baseURL='.........';
    break;
    case 'production':
        baseURL='.........';
    break;
}
const service:AxiosInstance = axios.create({
    timeout: 5000,
    baseURL
});
 
//请求拦截
service.interceptors.request.use(
    (config: AxiosRequestConfig) => {
        if(!config.noToken){
            const token = localStorage.getItem('pc/GDToken');
            if(token){
                config.header.Authorization = token
            }
        }
        return config;
    },
    (error: AxiosError) => {
        console.log(error);
        return Promise.reject();
    }
);
 
//响应 拦截
service.interceptors.response.use(
    (response: AxiosResponse) => {
        const { data } = reponse
        if (data.code === 0) {
            return Promise.resolve(data);
        } else {
            switch(data.code){
                case 401:
                    console.log('401');
                    toLogin();
                    break;
                case 403:
                    console.log('403');
                    toLogin();
                    break;
                default:
                    console.log('403');
            }
            Promise.reject();
        }
    },
    (error: AxiosError) => {
        console.log(error);
        toError();
        return Promise.reject();
    }
);
 
export default service;

api中新建的js文件

import request from "@/utils/request";
 
export const fetchData = () =>{
    return request({
        url:'.....',
        method:'get',
    })
}
 
export const fetchTest = (data) =>{
    return request({
        url:'.....',
        method:'get',
        params:data,
    })
}
 
export const changeTest = (data) =>{
    return request({
        url:'.....',
        method:'post',
        data:data,//放在data后就会包裹在Body内
    })
}

实际页面

<template>
</template>
<script setup>
import { onMounted } from "vue";
import { fetchData, fetchTest, } from "@/api/test";
const getList = async()=>{
    fetchData().then(res)=>{
        const { data } = res;
        ...
    }.catch((err)=>{})
}
onMounted(()=>{
    getList();
})
</script>
