oss进阶

oss是对象存储系统。

1.获取临时授权访问oss的token

package cn.hls.xjx.util.ossUtil;

import cn.hls.xjx.constant.Constant;
import cn.hls.xjx.util.IDUtil;
import com.alibaba.fastjson.JSONObject;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.profile.IClientProfile;
import com.aliyuncs.sts.model.v20150401.AssumeRoleRequest;
import com.aliyuncs.sts.model.v20150401.AssumeRoleResponse;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.servlet.http.HttpServletRequest;
import java.util.HashMap;
import java.util.Map;

/**
 *@Description STS临时授权访问OSS
 *@ClassName OssSecurityTokenUtil
 *@Author hasee
 *@Date 2020/2/11 14:45
 *@Version 1.0
 */
public class OssSecurityTokenUtil {
    public static Map<String,Object> getToken() {
        Map<String,Object> result = new HashMap<>();
        String id= IDUtil.getUUID().substring(0,16);
        id=id.replace(id.substring(0,1),"ossId");
        Map<String, String> tokenMessage = getSTSToken(id);
        if (tokenMessage.size() == 0) {
            result.put("status", 0);
            result.put("desc", "请求失败！");
            return result;
        }
        result.put("Expiration", tokenMessage.get("Expiration"));
        result.put("AccessKey", tokenMessage.get("AccessKey"));
        result.put("AccessKeySecret", tokenMessage.get("AccessKeySecret"));
        result.put("SecurityToken", tokenMessage.get("SecurityToken"));
        result.put("endpoint", OssProFileConstant.endpoint);
        result.put("bucket", OssProFileConstant.bucket);
        result.put("status", 1);
        result.put("desc", "请求成功！");
        return result;
    }

    public static JSONObject getServerCode(HttpServletRequest request) {
        JSONObject result = new JSONObject();
        result.put("serverCode", Constant.serverCode);
        return result;
    }

    public static Map<String, String> getSTSToken(String userId) {
        Map<String, String> tokenMessage = new HashMap<String, String>();
        try {
            // 添加endpoint（直接使用STS endpoint，前两个参数留空，无需添加region ID）
            DefaultProfile.addEndpoint("", "", "Sts", OssProFileConstant.endpoint);
            // 构造default profile（参数留空，无需添加region ID）
            IClientProfile profile = DefaultProfile.getProfile("cn-hangzhou", OssProFileConstant.accessKeyId, OssProFileConstant.accessKeySecret);
            // 用profile构造client
            DefaultAcsClient client = new DefaultAcsClient(profile);
            final AssumeRoleRequest request = new AssumeRoleRequest();
            request.setMethod(MethodType.POST);
            request.setRoleArn(OssProFileConstant.roleArn);
            //使用当前的用户id作为session名称
            request.setRoleSessionName(userId);
            request.setPolicy(OssProFileConstant.policy); // Optional
            request.setDurationSeconds(900L);
            final AssumeRoleResponse response = client.getAcsResponse(request);
            tokenMessage.put("Expiration", response.getCredentials().getExpiration());
            tokenMessage.put("AccessKey", response.getCredentials().getAccessKeyId());
            tokenMessage.put("AccessKeySecret", response.getCredentials().getAccessKeySecret());
            tokenMessage.put("SecurityToken", response.getCredentials().getSecurityToken());
            tokenMessage.put("RequestId", response.getRequestId());
        } catch (ClientException e) {
        }
        return tokenMessage;
    }
}

2.通过临时授权上传文件

package cn.hls.xjx.util.ossUtil;

import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;
import java.util.Map;
import com.aliyun.oss.ClientException;
import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import com.aliyun.oss.OSSException;
import com.aliyun.oss.model.Callback;
import com.aliyun.oss.model.Callback.CalbackBodyType;
import com.aliyun.oss.model.PutObjectRequest;
import com.aliyun.oss.model.PutObjectResult;
/**
 * OSS上传工具
 * @author hmy
 */
public class OssUploadUtils {
    /**
     * 简单上传
     * @param type：1表示字符串，2表示本地文件（绝对路径），3表示网络文件地址，4表示文件流，5表示字节数组
     * @param objectName：表示上传文件到OSS时需要指定包含文件后缀在内的完整路径，例如abc/efg/123.jpg   不包含buket
     * @param content：字符串
     * @param url：文件地址

     * @param bytes：字节数组
     */
    public static Boolean uploadOSS(Integer type,String objectName,String content,String url,InputStream inputStream,byte[] bytes){
        Map<String, Object> map = OssSecurityTokenUtil.getToken();
        // 创建OSSClient实例    试用sts授权生成临时的key和secret
        OSS ossClient = new OSSClientBuilder().build(OssProFileConstant.endpoint, map.get("AccessKey").toString(), map.get("AccessKeySecret").toString(), map.get("SecurityToken").toString());
        PutObjectRequest putObjectRequest = null;
        try {
            switch (type) {
                case 1:
                    // 上传字符串
                    putObjectRequest = new PutObjectRequest(OssProFileConstant.bucket, objectName,new ByteArrayInputStream(content.getBytes()));
                    ossClient.putObject(putObjectRequest);
                    break;
                case 2:

                    ossClient.putObject(putObjectRequest);
                    break;
                case 3:
                    // 上传网络流。
                    InputStream is = new URL(url).openStream();
                    ossClient.putObject(OssProFileConstant.bucket, objectName, is);
                    break;

                    ossClient.putObject(putObjectRequest);
                    break;
                default:
                    // 上传文件流。
                    ossClient.putObject(OssProFileConstant.bucket, objectName, inputStream);
                    break;
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            // 关闭OSSClient。
            ossClient.shutdown();
        }
        return true;
    }

    /**
     * 上传回调
     * @return
     */
    public static String callbackOSS(String descFileUrlName,Map<String, Object> map) throws IOException {
        String callbackUrl = "http://172.18.1.71:12080";
        // 创建OSSClient实例    试用sts授权生成临时的key和secret
        OSS ossClient = new OSSClientBuilder().build(OssProFileConstant.endpoint, map.get("AccessKey").toString(), map.get("AccessKeySecret").toString(), map.get("SecurityToken").toString());
        try {
            String content = "Hello OSS";
            PutObjectRequest putObjectRequest = new PutObjectRequest(OssProFileConstant.bucket, descFileUrlName,new ByteArrayInputStream(content.getBytes()));
            Callback callback = new Callback();
            callback.setCallbackUrl(callbackUrl);
//            callback.setCallbackHost("oss-cn-hangzhou.aliyuncs.com");
            callback.setCallbackBody("{\\\"bucket\\\":${bucket},\\\"object\\\":${object},"
                    + "\\\"mimeType\\\":${mimeType},\\\"size\\\":${size}" );
            callback.setCalbackBodyType(CalbackBodyType.JSON);
//            callback.addCallbackVar("x:var1", "value1");
//            callback.addCallbackVar("x:var2", "value2");
            putObjectRequest.setCallback(callback);

            PutObjectResult putObjectResult = ossClient.putObject(putObjectRequest);
            byte[] buffer = new byte[1024];
            putObjectResult.getResponse().getContent().read(buffer);
            putObjectResult.getResponse().getContent().close();

        } catch (OSSException oe) {

        } finally {
            ossClient.shutdown();
        }
        return "OK";
    }
}

3.url访问oss中的文件

    

    示例：当  桶名为：shipinziyuan-1    分布地域是 beijing  则如下访问

     https://shipinziyuan-1.oss-cn-beijing.aliyuncs.com/shipinceshi/3.jpg

4.oss配置域名访问（一般是二级域名）

      

     如绑定域名： up.xinjiaoxue.cn   点击提交后等待几分钟就可以如下访问：  

     https://up.xinjiaoxue.cn/shipinceshi/3.jpg

    ***实际上 up.xinjiaoxue.cn  替换了   shipinziyuan-1.oss-cn-beijing.aliyuncs.com
