谷粒商城学习日记（30）——使用OSS上传文件并整合

开通阿里云OSS服务并配置

开通OSS

登录阿里云账号控制台选择oss对象存储

点击开通

账号首次使用实名认证

配置

开通之后需要配置一个bucket列表
测试使用的话选择低频，其他情况自行决定

创建OSS代码上传服务

阿里云创建accesskeys

使用代码服务需要用到AccessKey ID和AccessKey Secre
这里我们创建一个

创建OSS模块

代码创建方式可以参考阿里云文档

创建新模块，gulimall-api
初始化使用spring.io
点上spring web 和 open feign

这里在后期维护的时候可以使用nacos配置中心
application.yml

spring:
  cloud:
    nacos:
      discovery:
        server-addr: 123.57.234.18:8848
    alicloud:
      access-key: 
      secret-key: 
      oss:
        endpoint: 	oss-cn-shanghai.aliyuncs.com
        bucket: gulimall-xfwang

  application:
    name: gulimall-api

server:
  port: 30000

启动类加注解

@EnableDiscoveryClient
@SpringBootApplication
public class GulimallApiApplication {

	public static void main(String[] args) {
		SpringApplication.run(GulimallApiApplication.class, args);
	}

}

创建oss加签接口
OssController.java

package com.xfwang.gulimall.api.controller;

 @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("/oss/policy")
    public R policy() {

        String host = "https://" + bucket + "." + endpoint;

        String format = new SimpleDateFormat("yyyy-MM-dd").format(new Date());

        String dir = format + "/";

        Map<String, String> respMap = null;
        try {
            long expireTime = 600;
            long expireEndTime = System.currentTimeMillis() + expireTime * 1000;
            Date expiration = new Date(expireEndTime);
            PolicyConditions policyConds = new PolicyConditions();
            policyConds.addConditionItem(PolicyConditions.COND_CONTENT_LENGTH_RANGE, 0, 1048576000);

            String postPolicy = ossClient.generatePostPolicy(expiration, policyConds);

            String encodedPolicy = BinaryUtil.toBaseString(binaryData);
            String postSignature = ossClient.calculatePostSignature(postPolicy);

            respMap = new LinkedHashMap<String, String>();
            respMap.put("accessid", accessId);
            respMap.put("policy", encodedPolicy);

            // respMap.put("expire", formatISO8601Date(expiration));

        } catch (Exception e) {
            // Assert.fail(e.getMessage());
            System.out.println(e.getMessage());
        }

        return R.ok().put("data", respMap);
    }
}

gateway网关路由

application.yml
添加路由

routes:
        - id: third_party_route
          uri: lb://mall-third-party
          predicates:
            - Path=/api/third-party/**
          filters:
            - RewritePath=/api/third-party/(?<segment>.*),/$\{segment}

联调前端品牌管理图标上传

使用自定义组件上传

在src/components

修改之前的品牌管理页面

brand-add-or-update.vue

    <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>

import SingleUpload from '@/components/upload/singleUpload';
  export default {
    components: {SingleUpload},
    data () {
    ...}

这时候重启项目，发现上传文件报错，是因为我们oss没配置跨域

我们去阿里云配置跨域
