谷粒商城项目踩坑及修复合辑

p46 renren-fast获取验证码报503

问题

现在renren-fast的springboot版本为2.6.6，如果直接引入gulimall-common，会出现springboot版本和springcloud版本不匹配，而且看弹幕和评论区说最好所用版本都和老师的一致，要不然后面出现无数问题。

解决方法

修改renren-fast的springboot版本

修改springboot版本为2.1.18.RELEASE，然后单独引入springCloud的nacos，不需要引入gulimall-common

修改idea设置

在进行上一步的修改之后，可能出现maven刷新不报错，代码不爆红，但是一运行就提示说程序包找不到，这样修改一下idea设置就行，即给Delegate IDE build打上勾

我在进行这一步之后就成功了，但是如果还有问题，记得检查一下服务有没有注册成功，如果是注册不成功，需要检查一下配置文件有没有写错

P64 给bucket设置了跨域还是报403

注意后端返回的是accessId，而不是accessid，所以前端也要修改

p76 Cannot read properties of undefined(reading ‘publish’)

原本代码

修改

安装工具

npm install pubsub-js

在页面中导入

import PubSub from 'pubsub-js'

去掉this关键字

页面代码

<template>

  <div>
    <el-cascader
      filterable
      clearable 
      placeholder="试试搜索：手机"
      v-model="paths"
      :options="categorys"
      :props="setting"
    >el-cascader>
  div>
template>

<script>
//这里可以导入其他文件（比如：组件，工具js，第三方插件js，json文件，图片文件等等）
//例如：import 《组件名称》 from '《组件路径》';
import PubSub from 'pubsub-js'

export default {
  //import引入的组件需要注入到对象中才能使用
  components: {},
  //接受父组件传来的值
  props: {
    catelogPath: {
      type: Array,
      default(){
        return [];
      }
    }
  },
  data() {
    //这里存放数据
    return {
      setting: {
        value: "catId",
        label: "name",
        children: "children"
      },
      categorys: [],
      paths: this.catelogPath
    };
  },
  watch:{
    catelogPath(v){
      this.paths = this.catelogPath;
    },
    paths(v){
      this.$emit("update:catelogPath",v);
      //还可以使用pubsub-js进行传值
      PubSub.publish("catPath",v);
    }
  },
  //方法集合
  methods: {
    getCategorys() {
      this.$http({
        url: this.$http.adornUrl("/product/category/list/tree"),
        method: "get"
      }).then(({ data }) => {
        this.categorys = data.data;
      });
    }
  },
  //生命周期 - 创建完成（可以访问当前this实例）
  created() {
    this.getCategorys();
  }
};

503

仔细检查配置文件中所配置的服务名称是否正确

P84 添加了品牌但品牌校验无法通过

P100 点击“规格”报404

  { path: '/product-attrupdate', component: _import('modules/product/attrupdate'), name: 'attr-update', meta: { title: '规格维护', isTab: true } }

发布商品上传图片报403原因Invalid according to Policy: Policy expired.

可能是电脑本地获取的时间慢了，可以将expireTime设置更大一点，比如说700，不行再设置更大一点

P180 按照价格区间查询不出来数据

要将"type"修改为double

P209 js二维数组求交集有问题

  ///找出所有skuIds的交集即是要切换到的sku，$(变量)：包装成一个JQuery元素
         let filterEle = skusList[0];
          for (let i = 1; i < skusList.length; i++) {
              filterEle = new Array();
              filterEle.push($(filterEle).filter(skusList[i])[0]);
          }

我这边求出来的 filterEle 最后都是没有定义，于是我改成自己的了

        let intersectionArr = getIntersection(skusList)
        let filterEle = intersectionArr[0]

    function getIntersection(skusList) {
        let skus1 = skusList[0];
        for (let i = 1; i < skusList.length; i++) {
            let skus2 = skusList[i];
            skus1 = getIntersectionOfTwoArr(skus1, skus2)
        }
        return skus1;
    };

    function getIntersectionOfTwoArr(skus1, skus2) {
        let intersectArr = new Array();
        for (let i = 0; i < skus1.length; i++) {
            for (let j = 0; j < skus2.length; j++) {
                if (skus1[i] == skus2[j]) {
                    intersectArr.push(skus1[i])
                }
            }
        }
        return intersectArr;
    };

由于比较懒，我使用的是最简单的遍历方式，当然还是存在很大的优化空间的，可以去LeetCode上面寻找相关的题目来学习

完结撒花

部分问题这里没有及时记录到，小伙伴们可以查看视频教程的弹幕和评论找答案啦！
后面的k8s部署，对机器的内存要求比较高，很多小伙伴可能玩不起来，但是也可以学习并记好笔记。希望到后面当你手头有几台服务器的时候，你可以将你的绝世神功使用出来。
感谢尚硅谷的教程，收获颇丰。
