- "template" : "static/index.html",
- "devServer": {
- "proxy": {
- "/api": {
- "target": "http://192.168.31.162:8288",
- "changeOrigin": true
- }
- }
- },
-
- "router" : {
- "mode" : "hash", // 路由模式
- "base" : "./"
- },
- "sdkConfigs" : {
- "maps" : {
- "amap" : {
- "key" : "ca8cde9d6d4d6658826713d31d3df9c2",
- "securityJsCode" : "",
- "serviceHost" : ""
- }
- }
- }
