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
首先肯定是开通oss服务了（免费的）：
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：
引入依赖：

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）：
赋予oss的读写权限：
然后复制好访问key和密钥：
复制endpoint：
来到nacos配置中心，创建个命名空间：
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：
解决方案：
使用服务端签名的方式进行上传：
服务端签名，写一个接口：
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.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; @RestController public class OssController { @Autowired OSS ossClient; @Value("${alibaba.cloud.oss.endpoint}") private String endpoint; @Value("${alibaba.cloud.oss.bucket}") private String bucket; @Value("${alibaba.cloud.access-key}") private String accessId; @RequestMapping("/oss/policy") public R 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 R.ok().put("data",respMap); } }

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：
