    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

    jsApiList: [] // 必填，需要使用的JS接口列表，所有JS接口列表见附录2
});

wx.ready(function(){
    //config信息验证后会执行ready方法，所有接口调用都必须在config接口获得结果之后，config是一个客户端的异步操作，所以如果需要在页面加载时就调用相关接口，则须把相关接口放在ready函数中调用来确保正确执行。对于用户触发时才调用的接口，则可以直接调用，不需要放在ready函数中。
});

wx.error(function(res){
    //config信息验证失败会执行error函数，如签名过期导致验证失败，具体错误信息可以打开config的debug模式查看，也可以在返回的res参数中查看，对于SPA可以在这里更新签名。
