1.以下是一个包含了部分常用配置选项的 app.json：
{
"pages": [
"pages/index/index",
"pages/logs/index"
],
"window": {
"navigationBarTitleText": "Demo"
},
"tabBar": {
"list": [{
"pagePath": "pages/index/index",
"text": "首页"
}, {
"pagePath": "pages/logs/index",
"text": "日志"
}]
},
"networkTimeout": {
"request": 10000,
"downloadFile": 10000
},
"debug": true,
"navigateToMiniProgramAppIdList": [
"wxe5f52902cf4de896"
]
}
2.每一个小程序页面也可以使用同名 .json 文件来对本页面的窗口表现进行配置，页面中配置项会覆盖 app.json 的 window 中相同的配置项
{
"navigationBarBackgroundColor": "#ffffff",
"navigationBarTextStyle": "black",
"navigationBarTitleText": "微信接口功能演示",
"backgroundColor": "#eeeeee",
"backgroundTextStyle": "light"
}
