wepy项目中使用async await

• 进入项目根目录，安装runtime包

npm install wepy-async-function --save

• 修改wepy.config.js加入runtime配置

       babel: {
            "presets": [
                "env"
            ],
            "plugins": [
                "transform-export-extensions",
                "syntax-export-extensions"
            ]
        }

• 在app.wpy中引入引入runtime包

import 'wepy-async-function'; 

• 在app.wpy中使API promise化

export default class extends wepy.app {

    constructor () {
        super();
        this.use('promisify');
    }

}

• 重启编译

wepy build --no-cache
