阿里----OSS对象存储服务

第一步、开启OSS服务，创建一个Bucket、创建一个用户并开启OSS权限

名称和地区根据自己需求填写，除了括出来的其他默认即可，创建bucket

创建一个AccessKey用户

创建好后，再次点击AccessKey管理 获取下面的两个字段信息，后面需要使用它来进行OSS对象管理

开启OSS跨域

---

第二步、引入依赖、添加配置

引入依赖

<!-- spring-cloud-starter-alicloud-oss OSS对象存储服务--> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alicloud-oss</artifactId> <version>${alicloud-oss.version}</version> </dependency>

添加配置

spring: application: name: cloud-oss cloud: alicloud: access-key: OSS用户的AccessKey ID secret-key: OSS用户的AccessKey SECRET oss: endpoint: 访问的节点域名，例如：oss-cn-shenzhen.aliyuncs.com bucket: yumbo-oss #这个根据自己的bucket名称填写，启动器没有本身没有这个配置

OSS的文档地址 Github文档地址(https://github.com/alibaba/spring-cloud-alibaba/blob/master/spring-cloud-alibaba-docs/src/main/asciidoc-zh/oss.adoc)

后端签名后通过javascript直传

文档地址

签名信息获取

编写一个Controller 示例代码如下

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 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; @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 Map<String, String> policy() { //https://gulimall-hello.oss-cn-beijing.aliyuncs.com/hahaha.jpg String host = "https://" + bucket + "." + endpoint; // host的格式为 bucketname.endpoint // callbackUrl为 上传回调服务器的URL，请将下面的IP和Port配置为您自己的真实信息。 // String callbackUrl = "http://88.88.88.88:8888"; 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 respMap; } }

为了聚合服务，所有的请求都经过网关先过滤 所以添加一个路由配置

spring: cloud: gateway: routes: - id: third_party_route uri: lb://要负载均衡到的Oss服务名 predicates: - Path=/api/thirdparty/** filters: - RewritePath=/api/thirdparty/(?<segment>.*),/$\{segment}
