uniapp因为要兼容小程序等，会重写wx对象，导致引入的jweixin-1.6.0.js中对象不生效。

综合网络资料，有两种解决方案：

一，通过npm工具引入

npm install jweixin-module --save

实际上是借用了wx的另一个对象jWeixin

//main.js

import jWeixin from 'jweixin-module'
Vue.prototype.$wx = jWeixin

// index.js

this.$wx.config({
    debug: true,
    appId,
    timestamp,
    nonceStr,
    signature,
    jsApiList,
})
this.$wx.ready(()=> {})

二，手动引入

鉴于uniapp会重写wx的特性，在初始化后，可以再手动引入js，覆盖原有的wx对象
