单/多文件上传组件

将课件中分布式基础\代码\前端组件\upload上传文件组件复制到项目中，

policy.js 上传函数封装

import http from '@/utils/httpRequest.js'
export function policy() {
    return new Promise((resolve, reject) => {
        http({
            url: http.adornUrl('/thirdparty/oss/policy'),
            method: 'get',
            params: http.adornParams({}),
        }).then(({ data }) => {
            resolve(data);
        })
    });
}

        duration: 1000,
      });
    },
  },
};
</script>
<style>
</style>

导入组件

在src\views\modules\product\brand-add-or-update.vue页面引入组件，

//在<script>标签中导入组件
import singleUpload from "@/components/upload/singleUpload"
 
//在export default中声明要用到的组件
  components:{
    singleUpload
  },

使用组件替换LOGO地址的输入框，

      <el-form-item label="品牌logo地址" prop="logo">
        <singleUpload v-model="dataForm.logo"></singleUpload>
      </el-form-item>

修改CORS允许跨域访问

阿里云官方介绍修改CORSopen in new window

从前端8002端口转到阿里云的bucket域名，会有跨域问题。跨域都是目标地址需要配置规则，所以在阿里云配置跨域规则，

操作步骤如下：

点击Bucket，点击“数据安全”->“跨域设置”

创建规则，

测试

“品牌管理”->“新增”

点击确定后，发现OSS管理控制台图片上传成功
