vue项目里怎么跳转到自己写的php文件，怎么通过axios访问php
之前用vue写了一个欢迎界面，然后用php写了后端的处理，但把php文件与vue整合时出现了错误，先是通过el-button跳转到php页面时网页并没有改变，而是进行了php文件的下载，这个我很纳闷。还有在html文件里通过axios访问php提示404 not found
报错截图
文件目录
html文件中访问php的部分代码
getdata() {
setInterval(() => {
axios.get('/src/assets/php/data.php').then(res => {
this.allincome = res.data;
});
}, 500)
} <form action="/src/php/welcome.php" method="POST" target="fmResult" id="data" name="dataform">
代码发一下

<?php
session_destroy();

这个是html页面的代码，文件结构如问题中所述，运行时提示php not found
使用绝对路径
