//create order
createUnifiedOrder(data={},opts={}){
    let wxpay=new WxPay(data);
    //
    return new Promise(function(resolve,reject){
        //
        //TODO
        //
        wxpay.createUnifiedOrder(data,function(err,result){
            if(err){
                //
                return reject(result);
            }
            //
            return resolve(result);
        });
    });
}
//change order status
changeUnifiedOrder(data={},opts={}){
    //TODO
}
```

## Koa Middleware Router

``` js
router.post('/xx/xx', async function(ctx,next){
    //
    //
    let handler = new KoaHandle();
    let res = await handler.createUnifiedOrder(data,opts).then(function(result){

        return result;
    }).catch(function(result){

        return result;
    });
    //
    ctx.body=res;
});

//
router.post('/your/wxpay/notify', async function(ctx,next){
    //
    //
    let handler = new KoaHandle();
    let res = await handler.changeUnifiedOrder(data,opts).then(function(result){
        //
        return WxPay.success();
    }).catch(function(result){
        //
        return WxPay.fail();
    });

    ctx.body=res;
})
