为什么请求帖子未运行

Question

我当前遇到request.post（）未运行的一些问题。我的代码以某种方式跳过了if和else语句中的request.post（）。谁能告诉我我做错了什么或如何改进我的代码？如果有人也向我解释我做错了，那将是很好的。

CurrentOrder.findOneAndUpdate(_id, orderBody, function (err, data) {
            if (err) return next(err)

            CurrentOrder.findOne(_id2, function(err, order) {
                if (err) return next(err)

                if(order.canadaTrackingStatus.length == 1 && orderBody.paymentStatus == 'paid'){
                    order.canadaTrackingStatus = [order.canadaTrackingStatus[0], {date: new Date(), status: '门店已揽收'}];
                    order.save(function(err) {
                        if (err) return next(err)
                        var modItems = merge_items(order.items)
