初始化cos客户端

    //初始化cos客户端public COSClient cosClientnew(String secretId, String secretKey, String regionName){// 1 初始化用户身份信息（secretId, secretKey）。// SECRETID 和 SECRETKEY 请登录访问管理控制台 https://console.cloud.tencent.com/cam/capi 进行查看和管理COSCredentials cred = new BasicCOSCredentials(secretId,secretKey);// 2 设置 bucket 的地域, COS 地域的简称请参见 https://cloud.tencent.com/document/product/436/6224// clientConfig 中包含了设置 region, https(默认 http), 超时, 代理等 set 方法, 使用可参见源码或者常见问题 Java SDK 部分。Region region = new Region(regionName);ClientConfig clientConfig = new ClientConfig(region);// 这里建议设置使用 https 协议// 从 5.6.54 版本开始，默认使用了 httpsclientConfig.setHttpProtocol(HttpProtocol.https);// 以下的设置，是可选的：// 设置 socket 读取超时，默认 30sclientConfig.setSocketTimeout(30*1000);// 设置建立连接超时，默认 30sclientConfig.setConnectionTimeout(30*1000);// 3 初始化 cos 客户端。return new COSClient(cred, clientConfig);}

测试读取数据

    @Testpublic void test01wwww1(){COSClient cosClient = cosClientnew(TencentConfig.SECRET_ID,TencentConfig.SECRET_KEY,TencentConfig.REGION_NAME);// Bucket 的命名格式为 BucketName-APPID ，此处填写的存储桶名称必须为此格式String bucketName = "donglin-1304838938";String key = "ldl.txt";try {ObjectMetadata objectMetadata = cosClient.getObjectMetadata(bucketName, key);System.out.println(objectMetadata.getContentLength());} catch (CosServiceException e) {e.printStackTrace();} catch (CosClientException e) {e.printStackTrace();}}
