"h5" : {
        "devServer" : {
            "disableHostCheck" : true,
            "proxy" : {
                "/api" : {
                    "target" : "http://xxxx:59113", //请求的目标域名
                    "changeOrigin" : true,
                    "secure" : false
                }
            },
            "port" : 8848,
            "https" : true
        },
        "router" : {
            "mode" : "hash",
            "base" : "/platform/runtime/epp/h5/"
        },
