OSS基础配置

上传的账号信息存储在应用服务器

上传前先找应用服务器要一个policy上传策略，生成防伪签名

OSS跨域设置

原生sdk方式上传

添加依赖包

<dependency>
    <groupId>com.aliyun.oss</groupId>
    <artifactId>aliyun-sdk-oss</artifactId>
    <version>3.8.0</version>
</dependency>

测试

// Endpoint以广州为例，其它Region请按实际情况填写。
String endpoint = "http://oss-cn-guangzhou.aliyuncs.com";
// 云账号AccessKey有所有API访问权限，建议遵循阿里云安全最佳实践，创建并使用RAM子账号进行API访问或日常运维，请登录 https://ram.console.aliyun.com 创建。
String accessKeyId = "<yourAccessKeyId>";
String accessKeySecret = "<yourAccessKeySecret>";

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

// 上传文件流。
InputStream inputStream = new FileInputStream("<yourlocalFile>");
ossClient.putObject("<yourBucketName>", "<yourObjectName>", inputStream);

// 关闭OSSClient。
ossClient.shutdown();

获取需要填写的密钥信息

完整测试代码

@Test
    void testOss() throws FileNotFoundException {
        // Endpoint以广州为例，其它Region请按实际情况填写。
        String endpoint = "http://oss-cn-guangzhou.aliyuncs.com";
        // 云账号AccessKey有所有API访问权限，建议遵循阿里云安全最佳实践，创建并使用RAM子账号进行API访问或日常运维，请登录 https://ram.console.aliyun.com 创建。
        String accessKeyId = "LTAI5tNTYKY13HpzJMFDmA2q";
        String accessKeySecret = "ONbLcR0lw56HHKyZqkfIWeAiIM5VFO";

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

        // 上传文件流。
        InputStream inputStream = new FileInputStream("C:\\Users\\WSKH\\Desktop\\test.png");
        ossClient.putObject("gulimall-wskh", "原生sdk测试上传.png", inputStream);

        // 关闭OSSClient。
        ossClient.shutdown();

        System.out.println("上传成功");
    }

阿里云sdk方式上传

添加依赖

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alicloud-oss</artifactId>
    <version>2.2.0.RELEASE</version>
</dependency>

在配置文件中添加用户id和密钥信息

最后在测试类中，自动注入OSS接口，直接使用即可

@SpringBootTest
class GulimallProductApplicationTests {

    @Autowired
    BrandService brandService;

    @Autowired
    OSS ossClient;

    @Test
    void testOss() throws FileNotFoundException {
        // 上传文件流。
        InputStream inputStream = new FileInputStream("C:\\Users\\WSKH\\Desktop\\test.png");
        ossClient.putObject("gulimall-wskh", "原生sdk测试上传2.png", inputStream);

        // 关闭OSSClient。
        ossClient.shutdown();

        System.out.println("上传成功");
    }

}

将oss配置加入nacos

在pulic命名空间下，创建gulimall-third-party.properties（名字可以自定义），之所以放在pulic下，而不是放在一个新建的命名空间下，是因为踩过坑，好像只有在pulic下才可以读取到（可能我没配置好环境）

配置中内容如下，格式采用properties而不是yml，一开始我是用yml无法正常获取配置信息，后改为properties就可以了

# 广州的地址
spring.cloud.alicloud.oss.endpoint=oss-cn-guangzhou.aliyuncs.com
# 入口令牌
spring.cloud.alicloud.access-key=xxx
# 密码令牌
spring.cloud.alicloud.secret-key=xxx
# 上传文件后要存储在哪个bucket中
spring.cloud.alicloud.oss.bucket=gulimall-wskh

然后是本地配置

# 服务名
spring.cloud.nacos.config.name=gulimall-third-party
# nacos地址
spring.cloud.nacos.config.server-addr=127.0.0.1:8848
# 命名空间id 不写则默认使用pulic命名空间下的配置
#spring.cloud.nacos.config.namespace=47b926dd-dd1f-4552-b874-fd040045bb48
# 指明dataId
spring.cloud.nacos.config.extension-configs[0].data-id=gulimall-third-party.properties
# 分组设置，默认组即可
spring.cloud.nacos.config.extension-configs[0].group=DEFAULT_GROUP
# 是否自动刷新配置信息
spring.cloud.nacos.config.extension-configs[0].refresh=true

ok，一切准备就绪，让我们试一下

@RestController
public class OssController {

    @Autowired
    OSS ossClient;

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

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

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


    @RequestMapping("/oss/policy")
    public Map<String, String> policy(){

        String host = "https://" + bucket + "." + endpoint; // host的格式为 bucketname.endpoint

        String format = new SimpleDateFormat("yyyy-MM-dd").format(new Date());
        String dir = format; // 用户上传文件时指定的前缀。

        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));

        } catch (Exception e) {
            // Assert.fail(e.getMessage());
            System.out.println(e.getMessage());
        } finally {
            ossClient.shutdown();
        }
        return respMap;
    }
}

打开浏览器，输入http://localhost:7999/oss/policy，按回车，看到以下信息，说明配置成功啦

加入网关的路由分发

在网关路由分发的配置中加入以下配置：

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

和前端整合测试

在前端的组件文件夹下创建upload文件夹，里面有三个文件，内容如下：

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);
        })
    });
}

singleUpload.vue 单文件上传组件

在需要的界面引入组件

使用组件

查看效果

如果报错503的话，可以在第三方服务模块中引入以下依赖：

        <!--    解决503问题    -->
