四、阿里云对象存储上传图片
1.在这里我们引入一个第三方服务模块
2.引入相关依赖
<!--升级spring cloud版本之后发现bootstrap.yml 失效了，阅读官方文档得知，需要新增一个引用来开启bootstrap.xml文件的读取，新版spring cloud默认是关闭读取了添加下面这个依赖就可以了--><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-bootstrap</artifactId></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alicloud-oss</artifactId></dependency><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-dependencies</artifactId><version>2.1.0.RELEASE</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement>
3.application.yml配置文件
spring:cloud:nacos:discovery:server-addr: 127.0.0.1alicloud:access-key: LTAI5t7gGh452gbMqVTCoU61secret-key: iulP0vpErve3ywyUZPofri9LNsdaBqoss:endpoint: oss-cn-qingdao.aliyuncs.combucket: gulimall-hellomy1application:name: gulimall-third-party
server:port: 30000
4.签名后直传
执行下面这个方法可以拿到令牌，然后就直接上传图片到阿里云
@RestController
public class OssController {@AutowiredOSS ossClient;@Value("${spring.cloud.alicloud.oss.endpoint}")private String endpoint;@Value("${spring.cloud.alicloud.oss.endpoint}")private String bucket;@Value("${spring.cloud.alicloud.access-key}")private String accessId;@RequestMapping("/oss/policy")public R policy(){// 阿里云账号AccessKey拥有所有API的访问权限，风险很高。强烈建议您创建并使用RAM用户进行API访问或日常运维，请登录RAM控制台创建RAM用户。// 填写Bucket名称，例如examplebucket。// 填写Host地址，格式为https://bucketname.endpoint。String host = "https://"+bucket+"."+endpoint;// 设置上传回调URL，即回调服务器地址，用于处理应用服务器与OSS之间的通信。OSS会在文件上传完成后，把文件上传信息通过此回调URL发送给应用服务器。//String callbackUrl = "https://192.168.0.0:8888";// 设置上传到OSS文件的前缀，可置空此项。置空后，文件将上传至Bucket的根目录下。String format = new SimpleDateFormat("yyyy-MM-dd").format(new Date());String dir = format + "/";//Map respMap = null; Map<String, String> respMap = new LinkedHashMap<String, String>();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.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);}@RequestMapping("/index")public String test(){return "hello";}
}
5.访问网关进行路径重写
