1.商品服务-品牌管理

把逆向生成的前端代码复制到前端src\views\modules\product

 

这样我们基本的增删改查就有了 

全局搜索isAuth,修改返回值为true 关闭eslint build\webpack.base.conf.js

const createLintingRule = () => ({
  // test: /\.(js|vue)$/,
  // loader: 'eslint-loader',
  // enforce: 'pre',
  // include: [resolve('src'), resolve('test')],
  // options: {
  //   formatter: require('eslint-friendly-formatter'),
  //   emitWarning: !config.dev.showEslintErrorsInOverlay
  // }
})

 1.1 快速显示开关

去elementui复制tabale表格-自定义列模板和开关

brand.vue

1.2 文件上传

开通阿里云对象存储，创建桶

 在文档里搜索OSS

 创建子账户添加OSS权限

1.2.1 测试上传

    @Test
    public void testUpload() throws FileNotFoundException {
//        // Endpoint以华东1（杭州）为例，其它Region请按实际情况填写。
//        String endpoint = "oss-cn-hangzhou.aliyuncs.com";
//        // 阿里云账号AccessKey拥有所有API的访问权限，风险很高。强烈建议您创建并使用RAM用户进行API访问或日常运维，请登录RAM控制台创建RAM用户。
//        String accessKeyId = "你的accessKeyId ";
//        String accessKeySecret = "你的accessKeySecret";
        // 填写Bucket名称，例如examplebucket。
        String bucketName = "gulimall-lll1";
        // 填写Object完整路径，完整路径中不能包含Bucket名称，例如exampledir/exampleobject.txt。
        String objectName = "exampledir/123.jpeg";
        // 填写本地文件的完整路径，例如D:\\localpath\\examplefile.txt。
        // 如果未指定本地路径，则默认从示例程序所属项目对应本地路径中上传文件流。
        String filePath= "C:\\Users\\liulo\\Desktop\\111.jpeg";

//        // 创建OSSClient实例。
//        OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);

        try {
            InputStream inputStream = new FileInputStream(filePath);
            // 创建PutObject请求。
            ossClient.putObject(bucketName, objectName, inputStream);
        } catch (OSSException oe) {
            System.out.println("Caught an OSSException, which means your request made it to OSS, "
                    + "but was rejected with an error response for some reason.");
            System.out.println("Error Message:" + oe.getErrorMessage());
            System.out.println("Error Code:" + oe.getErrorCode());
            System.out.println("Request ID:" + oe.getRequestId());
            System.out.println("Host ID:" + oe.getHostId());
        } catch (ClientException ce) {
            System.out.println("Caught an ClientException, which means the client encountered "
                    + "a serious internal problem while trying to communicate with OSS, "
                    + "such as not being able to access the network.");
            System.out.println("Error Message:" + ce.getMessage());
        } finally {
            if (ossClient != null) {
                ossClient.shutdown();
            }
        }
        System.out.println("上传完成！");
    }

1.2.2 使用springboot整合操作

1.引入oss-starter

2.配置文件配置key endpoint相关信息即可

3.注入OssClient 进行相关操作

1.3 创建子模块gulimall-third-party用来存放第三方服务

 

 1.3.1 修改pom文件

1.引入gulimall-common 排除mybatis-plus

<dependency>
    <groupId>com.atguigu.gulimall</groupId>
    <artifactId>gulimall-common</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <exclusions>
        <exclusion>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
        </exclusion>
    </exclusions>
</dependency>

2.把gulimall-common里的oss-starter放入third-party

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alicloud-oss</artifactId>
</dependency>

3.把阿里巴巴依赖管理方法third-party

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-alibaba-dependencies</artifactId>
    <version>2.1.0.RELEASE</version>
    <type>pom</type>
    <scope>import</scope>
</dependency>

1.3.2 创建bootstrap.properties

bootstrap.properties

spring.cloud.nacos.config.server-addr=127.0.0.1:8848
spring.cloud.nacos.config.namespace=0bcd0e23-64a8-432a-b75f-a357bc25a528

spring.cloud.nacos.config.ext-config[0].data-id=oss.yml
spring.cloud.nacos.config.ext-config[0].group=DEFAULT_GROUP
spring.cloud.nacos.config.ext-config[0].refresh=true

 application.yml

spring:
  application:
    name: gulimall-third-party
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848

server:
  port: 30000

1.4 服务端签名后直传

1.4.1 编写服务端代码

com.atguigu.gulimall.thirdparty.controller.OssController

package com.atguigu.gulimall.thirdparty.controller;

import com.aliyun.oss.OSS;
import com.aliyun.oss.common.utils.BinaryUtil;
import com.aliyun.oss.model.MatchMode;
import com.aliyun.oss.model.PolicyConditions;
import com.atguigu.gulimall.common.utils.R;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.LinkedHashMap;
import java.util.Map;

@RequestMapping("oss")
@RestController
public class OssController {

    @Autowired
    OSS ossClient;

    @Value("${spring.cloud.alicloud.oss.endpoint}")
    private String endpoint;

    @Value("${spring.cloud.alicloud.oss.bucket}")
    private String bucket;

    @Value("${spring.cloud.alicloud.access-key}")
    private String accessId;

    @RequestMapping("/policy")
    public R policy(){
        // 填写Host地址，格式为https://bucketname.endpoint。
        String host = "https://" + bucket + "." + endpoint;
        // 设置上传回调URL，即回调服务器地址，用于处理应用服务器与OSS之间的通信。OSS会在文件上传完成后，把文件上传信息通过此回调URL发送给应用服务器。
//        String callbackUrl = "https://192.168.0.0:8888";
        // 设置上传到OSS文件的前缀，可置空此项。置空后，文件将上传至Bucket的根目录下。
        String format = new SimpleDateFormat("yyyy-MM-dd").format(new Date());
        String dir = format + "/";

        Map<String, String> respMap = null;
        try {
            long expireTime = 30;
            long expireEndTime = System.currentTimeMillis() + expireTime * 1000;
            Date expiration = new Date(expireEndTime);
            PolicyConditions policyConds = new PolicyConditions();
            policyConds.addConditionItem(PolicyConditions.COND_CONTENT_LENGTH_RANGE, 0, 1048576000);
            policyConds.addConditionItem(MatchMode.StartWith, PolicyConditions.COND_KEY, dir);

            String postPolicy = ossClient.generatePostPolicy(expiration, policyConds);
            byte[] binaryData = postPolicy.getBytes("utf-8");
            String encodedPolicy = BinaryUtil.toBase64String(binaryData);
            String postSignature = ossClient.calculatePostSignature(postPolicy);

            respMap = new LinkedHashMap<String, String>();
            respMap.put("accessId", accessId);
            respMap.put("policy", encodedPolicy);
            respMap.put("signature", postSignature);
            respMap.put("dir", dir);
            respMap.put("host", host);
            respMap.put("expire", String.valueOf(expireEndTime / 1000));
            // respMap.put("expire", formatISO8601Date(expiration));

        } catch (Exception e) {
            // Assert.fail(e.getMessage());
            System.out.println(e.getMessage());
        }
        return R.ok().put("data",respMap);
    }
}

1.4.2 前端代码 

复制上传组件到前端

 

 替换bucket地址

 修改接口地址

 引入import SingleUpload from "@/components/upload/singleUpload";

使用

<el-form-item label="品牌logo地址" prop="logo">
        <!-- <el-input v-model="dataForm.logo" placeholder="品牌logo地址"></el-input> -->
        <single-upload v-model="dataForm.logo"></single-upload>
      </el-form-item>
