### 一 账号开启服务 ###

1.支付宝开启oss服务

2.创建bucket

### 二 .API开发使用 ###

[https://help.aliyun.com/document\_detail/52834.html?spm=a2c4g.11186623.6.931.2a5e53387iAk6W][https_help.aliyun.com_document_detail_52834.html_spm_a2c4g.11186623.6.931.2a5e53387iAk6W]

1.添加maven包

2.根据官方文旦就可以使用了。

### 三 spring-cloud-alibaba 整合oss ###

spring-cloud-alibaba 中文文档：[h][][ttps://github.com/alibaba/spring-cloud-alibaba/blob/master/README-zh.md][h]

[https://github.com/alibaba/aliyun-spring-boot/blob/master/aliyun-spring-boot-samples/aliyun-oss-spring-boot-sample/README-zh.md\#%E6%8E%A5%E5%85%A5-oss][https_github.com_alibaba_aliyun-spring-boot_blob_master_aliyun-spring-boot-samples_aliyun-oss-spring-boot-sample_README-zh.md_E6_8E_A5_E5_85_A5-oss]

步骤：

1.  导入所需包
2.  配置文件配置信息
3.  使用

--------------------

1.导入aliyun-oss-spring-boot-starter包如遇到unknown，导入如下代码

<dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>com.alibaba.cloud</groupId>
                    <artifactId>aliyun-spring-boot-dependencies</artifactId>
                    <version>1.0.0</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
      </dependencyManagement>

2.测试上传

@RunWith(SpringRunner.class)
    @SpringBootTest(classes = CmsApplication.class)
    public class OSSTest {
        @Autowired
        OSSClient ossClient;
        private  static String bucketName = "wwl-image-bucket";
        @Test
        public void saveFile() {
            // 上传文件流。
            try {
                InputStream inputStream = new FileInputStream("C:\\Users\\Administrator\\Desktop\\个人\\微信图片_20210115180426.jpg");
                ossClient.putObject(bucketName, "1082262.jpg", inputStream);
                // 关闭OSSClient。
                ossClient.shutdown();
                System.out.println("上传完成!!! ");
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            }
        }
    }

### 四 web端直传（服务端授权） ###

参考文档： [https://help.aliyun.com/document\_detail/31926.html?spm=a2c4g.11186623.6.1752.6eb76e02oWEJiF][https_help.aliyun.com_document_detail_31926.html_spm_a2c4g.11186623.6.1752.6eb76e02oWEJiF]

[https://help.aliyun.com/document\_detail/91868.htm?spm=a2c4g.11186623.2.10.78597d9c9Exg8C\#concept-ahk-rfz-2fb][https_help.aliyun.com_document_detail_91868.htm_spm_a2c4g.11186623.2.10.78597d9c9Exg8C_concept-ahk-rfz-2fb]

1.编写授权接口

@RestController
    public class OSSController {
    
        @Value("${alibaba.cloud.oss.endpoint}")
        private String endpoint;
    
        @Value("${alibaba.cloud.access-key}")
        private String accessId;
        private static String bucket = "wwl-image-bucket";
        @Autowired
        private OSS ossClient;
    
        @RequestMapping("/oss/policy")
        public Map<String, String> policy() {
    
            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。
            // 用户上传文件时指定的前缀。  此处定义每天建立一个文件夹
            String format = new SimpleDateFormat("yyyy-MM-dd").format(new Date());
            String dir = format + "/";
            // 创建OSSClient实例。
            Map<String, String> respMap = new LinkedHashMap<String, String>();
            try {
                long expireTime = 30;
                long expireEndTime = System.currentTimeMillis() + expireTime * 1000;
                Date expiration = new Date(expireEndTime);
                // PostObject请求最大可支持的文件大小为5 GB，即CONTENT_LENGTH_RANGE为5*1024*1024*1024。
                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));
            } catch (Exception e) {
                // Assert.fail(e.getMessage());
                System.out.println(e.getMessage());
            } finally {
                ossClient.shutdown();
            }
            return respMap;
    
    
        }
    
    }

响应数据：

{"accessid":"LTAI5tKmMBiEaRvb88JAid9Q","policy":"eyJleHBpcmF0aW9uIjoiMjAyMS0wMy0zMFQxMTozMzoxMC4wMDRaIiwiY29uZGl0aW9ucyI6W1siY29udGVudC1sZW5ndGgtcmFuZ2UiLDAsMTA0ODU3NjAwMF0sWyJzdGFydHMtd2l0aCIsIiRrZXkiLCIyMDIxLTAzLTMwLyJdXX0=","signature":"RY0eFexHuyBxPWM7X2N2LhVysgs=","dir":"2021-03-30/","host":"https://wwl-image-bucket.https://oss-cn-shenzhen.aliyuncs.com","expire":"1617103990"}

配置完后记得阿里云跨域授权
