开发项目必然少不了通过接口获取获取，这就用到了axios
axios官网

一、安装依赖

npm install axios

二、封装通用请求工具

src/utils/request.ts

import axios from 'axios'
import { ElNotification , ElMessageBox, ElMessage, ElLoading } from 'element-plus'
import { getToken } from '@/utils/auth'
import errorCode from '@/utils/errorCode'
import { tansParams, blobValidate } from '@/utils/mis'
import cache from '@/plugins/cache'
import { saveAs } from 'file-saver'
import useUserStore from '@/store/modules/user'

let downloadLoadingInstance;
// 是否显示重新登录
export let isRelogin = { show: false };

axios.defaults.headers['Content-Type'] = 'application/json;charset=utf-8'
// 创建axios实例
const service = axios.create({
  // axios中请求配置有baseURL选项，表示请求URL公共部分
  baseURL: import.meta.env.VITE_APP_BASE_API,
  // 超时
  timeout: 10000
})

// request拦截器
service.interceptors.request.use(config => {
  // 是否需要设置 token
  const isToken = (config.headers || {}).isToken === false
  // 是否需要防止数据重复提交
  const isRepeatSubmit = (config.headers || {}).repeatSubmit === false
  if (getToken() && !isToken) {
    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
  }
  if(config.Headers){
    config.headers['Content-Type'] = config.Headers['Content-Type']
  }
  // get请求映射params参数
  if (config.method === 'get' && config.params) {
    let url = config.url + '?' + tansParams(config.params);
    url = url.slice(0, -1);
    config.params = {};
    config.url = url;
  }
  if (!isRepeatSubmit && (config.method === 'post' || config.method === 'put'|| config.method === 'delete')) {
    const requestObj = {
      url: config.url,
      data: typeof config.data === 'object' ? JSON.stringify(config.data) : config.data,
      time: new Date().getTime()
    }
    const requestSize = Object.keys(JSON.stringify(requestObj)).length; // 请求数据大小
    const limitSize = 5 * 1024 * 1024; // 限制存放数据5M
    if (requestSize >= limitSize) {
      console.warn(`[${config.url}]: ` + '请求数据大小超出允许的5M限制，无法进行防重复提交验证。')
      return config;
    }
    // const sessionObj = cache.session.getJSON('sessionObj')
    cache.session.setJSON('sessionObj', requestObj)
    // if (sessionObj === undefined || sessionObj === null || sessionObj === '') {
    //   cache.session.setJSON('sessionObj', requestObj)
    // } else {
    //   const s_url = sessionObj.url;                // 请求地址
    //   const s_data = sessionObj.data;              // 请求数据
    //   const s_time = sessionObj.time;              // 请求时间
    //   const interval = 100;                       // 间隔时间(ms)，小于此时间视为重复提交
    //   // && requestObj.time - s_time < interval
    //   if (s_data === requestObj.data && s_url === requestObj.url) {
    //     const message = '数据正在处理，请勿重复提交';
    //     console.warn(`[${s_url}]: ` + message)
    //     return Promise.reject(new Error(message))
    //   } else {
    //     cache.session.setJSON('sessionObj', requestObj)
    //   }
    // }
  }
  return config
}, error => {
    console.log(error)
    Promise.reject(error)
})

// 响应拦截器
service.interceptors.response.use(res => {
    // 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 = errorCode[code] || res.data.msg || errorCode['default']
    // 二进制数据则直接返回
    if (res.request.responseType ===  'blob' || res.request.responseType ===  'arraybuffer') {
      return res.data
    }
    if (code === 401) {
      if (!isRelogin.show) {
        isRelogin.show = true;
        ElMessageBox.confirm('登录状态已过期，您可以继续留在该页面，或者重新登录', '系统提示', { confirmButtonText: '重新登录', cancelButtonText: '取消', type: 'warning' }).then(() => {
            isRelogin.show = false;
            useUserStore().logOut().then(() => {
              location.href = '/index';
            })
        }).catch(() => {
          isRelogin.show = false;
        });
      }
      return Promise.reject('无效的会话，或者会话已过期，请重新登录。')
    } else if (code === 500) {
      ElMessage({ message: msg, type: 'error' })
      return Promise.reject(new Error(msg))
    } else if (code === 601) {
      ElMessage({ message: msg, type: 'warning' })
      return Promise.reject(new Error(msg))
    } else if (code !== 200&& code !== 400) {
      ElNotification.error({ title: msg })
      return Promise.reject('error')
    } else {
      return  Promise.resolve(res.data)
    } 
  },
  error => {
    console.log('err' + error)
    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({ message: message, type: 'error', duration: 5 * 1000 })
    return Promise.reject(error)
  }
)

// 通用下载方法
export function download(url, params, filename, config) {
  downloadLoadingInstance = ElLoading.service({ text: "正在下载数据，请稍候", background: "rgba(0, 0, 0, 0.7)", })
  return service.post(url, params, {
    transformRequest: [(params) => { return tansParams(params) }],
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
    responseType: 'blob',
    ...config
  }).then(async (data) => {
    const isBlob = blobValidate(data);
    if (isBlob) {
      const blob = new Blob([data])
      saveAs(blob, filename)
    } else {
      const resText = await data.text();
      const rspObj = JSON.parse(resText);
      const errMsg = errorCode[rspObj.code] || rspObj.msg || errorCode['default']
      ElMessage.error(errMsg);
    }
    downloadLoadingInstance.close();
  }).catch((r) => {
    console.error(r)
    ElMessage.error('下载文件出现错误，请联系管理员！')
    downloadLoadingInstance.close();
  })
}

export default service

三、api请求模块化管理

在src下创建api文件夹，新建文件user.ts用来管理登录等用户相关的接口

import request from '@/utils/request'
export const login = (data:object) => {
    return request({
      url: '/api/user/login',
      method: 'post',
      data
    })
}

四、新建login.vue/调用login接口

1、新建login.vue页面

<template>
  <div class="login">
    <div class="loginMain">
      
      <div class="login-right">
        <el-form ref="loginRef" :model="loginForm" :rules="loginRules" class="login-form">
          <h3 class="title">登录</h3>
          <span class="title-btm"></span>
          <el-form-item prop="username">
            <el-input
              v-model="loginForm.username"
              type="text"
              size="large"
              auto-complete="off"
              placeholder="账号"
            >
              <template #prefix><svg-icon icon-class="user" class="el-input__icon input-icon" /></template>
            </el-input>
          </el-form-item>
          <el-form-item prop="password">
            <el-input
              v-model="loginForm.password"
              type="password"
              size="large"
              auto-complete="off"
              placeholder="密码"
              @keyup.enter="handleLogin"
            >
              <template #prefix><svg-icon icon-class="password" class="el-input__icon input-icon" /></template>
            </el-input>
          </el-form-item>
          
          <el-form-item  class="loginActBtn">
            <el-button
              :loading="loading"
              size="large"
              type="primary"
              style="width:100%;"
              @click.prevent="handleLogin"
            >
              <span >登 录</span>
            </el-button>
          </el-form-item>
        </el-form>
      </div>
      
    </div>
  </div>
</template>

<script setup>

    setTimeout(timer, 1000)
  } else {
    disabled.value = false
  }

if(time.value>0){
  disabled.value = true
  timer()
}

const text = computed(() => {

})

watch(route, (newRoute) => {
    redirect.value = newRoute.query && newRoute.query.redirect;
}, { immediate: true });

function handleLogin() {
  loginRef.value.validate(valid => {
    if (valid) {
      loading.value = true;
      Cookies.remove("username");
      Cookies.remove("password");
      const params = JSON.parse(JSON.stringify(loginForm.value));
      // 调用action的登录方法
      userStore.login(params).then((res) => {
        const query = route.query;
        const otherQueryParams = Object.keys(query).reduce((acc, cur) => {
          if (cur !== "redirect") {
            acc[cur] = query[cur];
          }
          return acc;
        }, {});
        router.push({ path: redirect.value || "/", query: otherQueryParams });
      }).catch((err) => {
        ElMessage({ message: err, type: 'warning' })
        loading.value = false;
      });
    }
  });
}



function getCookie() {
  const username = Cookies.get("username");
  const password = Cookies.get("password");
  loginForm.value = {
    username: username === undefined ? loginForm.value.username : username,
    password: password === undefined ? loginForm.value.password : decrypt(password),
  };
}

getCookie();
