两种方式:
1、manifest.json中配置

javascript
"h5" : {
"template" : "static/index.html",
"devServer" : {
"port" : 9090,
"https" : false,
"proxy":{
"/prod-api":{
"target":"http://192.168.30.226:8997",
"changeOrigin":true,
"pathRewrite":{
"^/prod-api":""
}
}
}
},
"title" : "RuoYi-App",
"router" : {
"mode" : "hash",
"base" : "./"
}
}
2、项目中增加vue.config.js

添加以上代码。
