一.app.json

使用app.json文件來(lái)對(duì)微信小程序進(jìn)行全局配置，決定頁(yè)面文件的路徑、窗口表現(xiàn)、設(shè)置網(wǎng)絡(luò)超時(shí)時(shí)間、設(shè)置多 tab 等.

注意在.json不能注釋，否則會(huì)出錯(cuò)。

二.工具欄tabBar

如果我們的小程序是一個(gè)多 tab 應(yīng)用（客戶端窗口的底部或頂部有 tab 欄可以切換頁(yè)面），那么我們可以通過(guò) tabBar 配置項(xiàng)指定 tab 欄的表現(xiàn)，以及 tab 切換時(shí)顯示的對(duì)應(yīng)頁(yè)面。

tabBar 是一個(gè)數(shù)組，只能配置最少2個(gè)、最多5個(gè) tab，tab 按數(shù)組的順序排序
