SpringCloudAlibaba整合oss官网示例：[https://github.com/alibaba/aliyun-spring-boot/tree/master/aliyun-spring-boot-samples/aliyun-oss-spring-boot-sample][https_github.com_alibaba_aliyun-spring-boot_tree_master_aliyun-spring-boot-samples_aliyun-oss-spring-boot-sample]

首先肯定是开通oss服务了（免费的）：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JhaWt1bmxvbmc_size_16_color_FFFFFF_t_70]  
然后创建一个bucket：

然后新建一个module，作为专门处理第三方服务的微服务：

根据图片步骤，进行子账号创建（避免将自己的满权限key暴露在代码里）：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JhaWt1bmxvbmc_size_16_color_FFFFFF_t_70 3]  
赋予oss的读写权限：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JhaWt1bmxvbmc_size_16_color_FFFFFF_t_70 4]  
然后**复制好**访问key和密钥：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JhaWt1bmxvbmc_size_16_color_FFFFFF_t_70 5]  
复制endpoint：

来到nacos配置中心，创建个命名空间：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JhaWt1bmxvbmc_size_16_color_FFFFFF_t_70 7]  
创建配置文件：

创建bootstrap.properties：

# 应用名称
    spring.application.name=gulimall-third-party
    # 应用服务 WEB 访问端口
    server.port=30000
    
    #注册中心
    spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848
    
    #配置中心
    spring.cloud.nacos.config.server-addr=127.0.0.1:8848
    #命名空间
    spring.cloud.nacos.config.namespace=91941f1c-d508-4ece-8737-6920bb626206
    
    spring.cloud.nacos.config.ext-config[0].data-id=oss.properties
    spring.cloud.nacos.config.ext-config[0].refresh=true

测试：

@Autowired
        OSSClient ossClient;
    
        @Test
        public void contextLoads() throws FileNotFoundException { 
            FileInputStream in = new FileInputStream("C:\\Users\\baikunlong\\Desktop\\images\\流浪猫狗救助协会_files\\1.jpg");
            ossClient.putObject("bklgulimall","小猫1.jpg",in);
            ossClient.shutdown();
            System.out.println("上传完成");
        }

到这里就能正常上传文件了。

# 进入主题 #

经过上面的操作，虽然能上传文件了，但是存在以下问题：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JhaWt1bmxvbmc_size_16_color_FFFFFF_t_70 9]  
**解决方案：**  
使用服务端签名的方式进行上传：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JhaWt1bmxvbmc_size_16_color_FFFFFF_t_70 10]  
服务端签名，写一个接口：

            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));
                // respMap.put("expire", formatISO8601Date(expiration));
    
    
            } catch (Exception e) { 
                // Assert.fail(e.getMessage());
                System.out.println(e.getMessage());
            }
    
            return R.ok().put("data",respMap);
        }
    }

参考官网：[https://help.aliyun.com/document\_detail/91868.html?spm=a2c4g.11186623.2.10.56077d9cJ5BDOY][https_help.aliyun.com_document_detail_91868.html_spm_a2c4g.11186623.2.10.56077d9cJ5BDOY]

访问测试：

因为要使用网关统一访问，配置下规则：

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

重启网关后访问网关88：

接下来对接前端：  
首先去权限管理下设置允许跨域：

然后再搞前端代码。

大致流程为：

1.  选择文件
2.  请求得到签名
3.  上传表单数据

传递如下参数即可：
