华为云obs存储-入门

1.购买服务

2.创建桶：自己设置，加密方式也自己设置

 3.将桶的3个基本参数记住，后台开发要用

4.在我的凭证里面设置访问密钥，会导出csv文件，将里面的key和keyid拿出来

 5.后台开发

　　5.0 主要依赖

　　　　

<dependency>
    <groupId>com.huaweicloud</groupId>
    <artifactId>esdk-obs-java</artifactId>
    <version>3.19.7</version>
</dependency>

　　5.1 将之前提到的5个参数放在yml里面

　　　　

　　5.2 service层

　　　　

@Service
public class UploadService {
    @Value("${huawei.accessKeyId}")
    private String accessKeyId;// 华为云的 Access Key Id
    @Value("${huawei.accessKey}")
    private String accessKeySecret;// 华为云的 Access Key Secret
    @Value("${huawei.endpoint}")
    private String endpoint; // 华为云连接的地址节点
    @Value("${huawei.obsBucketName}")
    private String obsBucketName; // 创建的桶的名称
    @Value("${huawei.url}")
    private String url; // 访问OBS文件的url
    private  ObsClient obsClient=null;
    /**
     * @Description: 文件上传
     * @Param: [bucketName, fileName, localFile]
     * @return: com.obs.services.model.PutObjectResult
     * @Author: hyy
     * @Date: 2021/6/25
     */
    public String putLocalFile()  {
        String path="D:\other\demo.jpg";
        File file=new File(path);
        UUID uuid=UUID.randomUUID();
        String originalFileName = uuid.toString().replace("-","")+"_demo.jpg";
        FileInputStream fis=null;
        ObsClient obsClient =null;
        PutObjectResult putObjectResult = null;
        String requestId=null;
        try {
            fis  = new FileInputStream(file);
            obsClient = getObsClient(this.obsClient);
            putObjectResult = obsClient.putObject(obsBucketName, originalFileName, fis);
            requestId = putObjectResult.getRequestId();
        }catch (Exception e){
            e.printStackTrace();
        }finally {
            try {
                obsClient.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return  requestId;
    }
    public ObsClient getObsClient(ObsClient obsClient) {
        if(obsClient == null) {
            obsClient = new ObsClient(accessKeyId, accessKeySecret, endpoint);

        }
        return obsClient;
    }

}

　　5.3 controller层

@RestController
public class UpLoadFile {
    @Autowired
    private UploadService uploadService;
    @RequestMapping("/upload")
    public String load(){
        return uploadService.putLocalFile();
    }

}

6.在云服务器看结果，完美储存
