3.0购物车点击优惠券不展示

1、链接：/components/couponListWindow/index.vue

方便复制：

<view v-if="coupon.count[0]" class="h-100 flex-y-center" :class="coupon.type === 0 ? 'active' : ''" @tap="setType(0)">通用券</view>
<view v-if="coupon.count[1]" class="h-100 flex-y-center" :class="coupon.type === 1 ? 'active' : ''" @tap="setType(1)">品类券</view>
<view v-if="coupon.count[2]" class="h-100 flex-y-center" :class="coupon.type === 2 ? 'active' : ''" @tap="setType(2)">商品券</view>
<view v-if="coupon.count[3]" class="h-100 flex-y-center" :class="coupon.type === 3 ? 'active' : ''" @tap="setType(3)">品牌券</view>

2、链接：/pages/order_addcart/order_addcart.vue

查找函数getCouponList（），进行替换

方便复制：

getCouponList(type) {
				let that = this,
				obj = {
					page: 1,
					limit: 20,
					product_id: that.id ? that.id : '',
					type: type
				};
				getCoupons(obj).then(res => {
					let count = res.data.count;
					that.$set(that.coupon, 'count', count);
					if (type === undefined || type === null) {
						let indexs = 0,list = [];
						count.forEach((item,index)=>{
							if(item !=0){
								return that.indexs = index;
							}
						})
						that.$set(that.coupon, 'type', indexs);
						res.data.list.forEach(item=>{
							if(item.type == indexs){
								that.$set(item,'ruleshow',false);
								list.push(item)
							}
						})
						that.$set(that.coupon, 'list', list);
					} else {
						res.data.list.map(item=>{
							that.$set(item,'ruleshow',false);
						})
						that.$set(that.coupon, 'list', res.data.list);
					}
				});
			},
