"global": {
        "webviewParameter": {
            "titleNView": {
                "autoBackButton": true,
                "backgroundColor": "#f7f7f7",//导航栏背景色

                "titleSize": "17px"
            },
            "statusbar": {
                //系统状态栏样式(前景色)
                "style": "dark"
            },
            "appendCss": "",
            "appendJs": ""
        },
        "easyConfig": {
            "quit": {
                "toast": {
                    "showFeedback": false //不显示“反馈意见”链接，默认为true
                }
            }
    }
},
