wx.config({ 
     debug: true, // 开启调试模式,调用的所有api的返回值会在客户端alert出来，若要查看传入的参数，可以在pc端打开，参数信息会通过log打出，仅在pc端时才会打印
     appId: '', // 必填，公众号的唯一标识
     timestamp: , // 必填，生成签名的时间戳
     nonceStr: '', // 必填，生成签名的随机串
     signature: '',// 必填，签名
     jsApiList: [], // 必填，需要使用的JS接口列表
     openTagList: [] // 可选，需要使用的开放标签列表，例如['wx-open-launch-app']
    })

对于path属性，所声明的页面路径必须添加`.html`后缀，如`pages/home/index.html`。  
开放标签成功时才能看到button，仅真机测试有效。微信开发者工具无法展示button，且console提示错误`[Vue warn]: Unknown custom element: <wx-open-launch-weapp> - did you register the component correctly? For recursive components, make sure to provide the "name" option.`
