根目录mainjs文件引入axios
vbnet
import { createApp } from 'vue'
import './style.css'
import App from './App.vue'
import router from './router' //引入router
import ElementPlus from 'element-plus' //引入ElementPlus
const app=createApp(App)
app.use(router) //使用router
app.use(ElementPlus) //使用ElementPlus
app.mount('#app')三：登录页面发送登录请求：发送请求，成功则用localStorge用户id
成功后跳转页面router.push('/page')
vbnet
const submitForm = () => {
loginForm.value.validate((valid) => {
if (valid) {
const resp = axios.post("/api/base/login",
{
username: form.username,
pwd: form.password
}
).then(resp => {
debugger
if (resp.data.code == 500) {
alert(resp.data.message)
}
if (resp.data.code == 200) {
localStorage.setItem('username', resp.data.data.id)
router.push('/page')
}
})
// Handle login logic here
} else {
alert('登录失败');
}
});
};
objectivec
<template>

import { ref, reactive } from 'vue';
import { useRouter } from 'vue-router';
import axios from "axios";
export default {

setup() {

}
});

loginForm,
form,
rules,

}
};
</script>四：解决跨域问题：配置Vite服务器的代理功能来实现
出现CORS跨域异常：
yaml
{
"message": "Request failed with status code 404",
"name": "AxiosError",
"stack": "AxiosError: Request failed with status code 404\n at settle (http://localhost:5173/node_modules/.vite/deps/axios.js?v=082c756d:1216:12)\n at XMLHttpRequest.onloadend (http://localhost:5173/node_modules/.vite/deps/axios.js?v=082c756d:1562:7)\n at Axios.request (http://localhost:5173/node_modules/.vite/deps/axios.js?v=082c756d:2078:41)",
"config": {
"transitional": {
"silentJSONParsing": true,
"forcedJSONParsing": true,
"clarifyTimeoutError": false
},
"adapter": [
"xhr",
"http",
"fetch"
],
"transformRequest": [
null
],
"transformResponse": [
null
],
"timeout": 0,

"xsrfHeaderName": "X-XSRF-TOKEN",
"maxContentLength": -1,
"maxBodyLength": -1,
"env": {},
"headers": {
"Accept": "application/json, text/plain, */*",
"Content-Type": "application/json"
},
"method": "post",
"url": "/api/baseStudentCourse/login",
"data": "{\"username\":\"sdafasda\",\"pwd\":\"adsfadfadsfa\"}"
},
"code": "ERR_BAD_REQUEST",
"status": 404
}
解决跨域异常：vite配置代理
-
打开项目中的vite.config.js文件（如果你使用的是vite.config.ts，则是相同的配置）。
-
在配置文件中，添加一个proxy配置项，指定需要代理的API地址以及相应的目标服务器地址
默认配置：
swift
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
// https://vitejs.dev/config/
export default defineConfig({
plugins: [vue()],
})变更后配置：
yaml
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
// https://vitejs.dev/config/
export default defineConfig({
plugins: [vue()],
// 添加代理配置
server: {
proxy: {
'/api': {
target: 'http://localhost:8092/', // 目标服务器地址
changeOrigin: true, // 是否改变源地址
rewrite: (path) => path.replace(/^\/api/, ''), // 重写路径
}
}
}
})查看发送的CURL：
yaml
curl 'http://localhost:5173/api/base/login' \
-H 'Accept: application/json, text/plain, */*' \
-H 'Accept-Language: zh-CN,zh;q=0.9' \
-H 'Connection: keep-alive' \
-H 'Content-Type: application/json' \
-H 'Origin: http://localhost:5173' \
-H 'Referer: http://localhost:5173/login' \
-H 'Sec-Fetch-Dest: empty' \
-H 'Sec-Fetch-Mode: cors' \
-H 'Sec-Fetch-Site: same-origin' \
-H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Safari/537.36' \
-H 'sec-ch-ua: "Google Chrome";v="125", "Chromium";v="125", "Not.A/Brand";v="24"' \
-H 'sec-ch-ua-mobile: ?0' \
-H 'sec-ch-ua-platform: "Windows"' \
--data-raw '{"username":"asdfadsf","pwd":"adfadfaf"}'
http://localhost:5173/api/base/login 代理到 http://localhost:8092/base/login
五：页面效果：
登录成功：
登录失败：
