阿里云 oss （二）生成令牌

文档：https://help.aliyun.com/document_detail/44075.html

一，添加依赖

            <!--      oss begin      -->
            <dependency>
                <groupId>com.aliyun.oss</groupId>
                <artifactId>aliyun-sdk-oss</artifactId>
                <version>3.13.0</version>
            </dependency>
            
            <dependency>
                <groupId>com.aliyun</groupId>
                <artifactId>dysmsapi20170525</artifactId>
                <version>2.0.4</version>
            </dependency>
            <!--      oss end      -->

二，配置文件

#aliyun oss
aliyun:
  oss_bucket_map: # Map-> sence : bucket
    advertisement: bucketName
    test: testval
  main_domain: bucketName
  aliyun_sms_sign: 1
  aliyun_sms_templet: 1
  ossEndpointValue: oss-cn-hangzhou.aliyuncs.com
  ossEndpointInner: inner
  ossAccessKeyId: 你的AccessKeyId
  ossAccessKeySecret: 你的AccessKeySecret
  ossStsRegion: region
  ossStsSessionName: session_name
  ossStsExpire: 1000
  ossStsRoleId: 1
  ossStsEndpoint: endpoint
  ossStsAccessKeyId: accessKeyId
  ossStsAccessKeySecret: accessKeySecret

import com.tenyears.model.common.ApiResult;
import com.tenyears.webCommon.config.oss.*;
import com.tenyears.webCommon.service.service.OSSService;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
 
import java.util.Map;
 
/**

 */
 
/**
 * oss 文件上传
 */
@RestController
@RequestMapping("api/oss")
public class OSSController {
 
    @Autowired
    OSSService manager;
    @Autowired
    BaseConfig configBase;
 
    /**

     * key : 场景 ,value : Bucket

     */

        result.setCodeToSuccessed(configBase.getOssBucketMap());

        AliyunOssAutoSignRequest reqData=request.getData();
 
        AliyunOSSWriteConfig aliyunOSSWriteConfig = manager.buildConfig(reqData.getFileScene() ,reqData.getFileName());
        AliyunOSSSignConfig signConfig = manager.generateSign(aliyunOSSWriteConfig.getFolderName());
        AliyunOSSConfig config = new AliyunOSSConfig();
        config.setBucket(aliyunOSSWriteConfig.getBucket());
        config.setAccessKeyId(configBase.getOssAccessKeyId());

        config.setFileUrl(config.getHost() + "/" + config.getFilePath());
        result.setCodeToSuccessed(config);
        return result;
    }
}

ApiRequest<T> 和 ApiResult<T> 就不展示了，以前文档有。

你们直接返回自己的实体对象
