篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了第180天学习打卡(项目 谷粒商城22 云存储开通与使用 阿里云对象存储 OOS获取服务端签名)相关的知识,希望对你有一定的参考价值。
云存储开通与使用
SpringCloudAlibaba-OSS
阿里云对象存储
SDK管理文件 网址:阿里云帮助中心-阿里云,领先的云计算服务提供商 (aliyun.com)
安装SDK(在gulimall-product的pom.xml中)
<dependency>
<groupId>com.aliyun.oss</groupId>
<artifactId>aliyun-sdk-oss</artifactId>
<version>3.10.2</version>
</dependency>
上传文件流
// yourEndpoint填写Bucket所在地域对应的Endpoint。以华东1(杭州)为例,Endpoint填写为https://oss-cn-hangzhou.aliyuncs.com。
String endpoint = "yourEndpoint";
// 阿里云账号AccessKey拥有所有API的访问权限,风险很高。强烈建议您创建并使用RAM用户进行API访问或日常运维,请登录RAM控制台创建RAM用户。
String accessKeyId = "yourAccessKeyId";
String accessKeySecret = "yourAccessKeySecret";
// 创建OSSClient实例。
OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
// 填写本地文件的完整路径。如果未指定本地路径,则默认从示例程序所属项目对应本地路径中上传文件流。
InputStream inputStream = new FileInputStream("D:\\\\localpath\\\\examplefile.txt");
// 依次填写Bucket名称(例如examplebucket)和Object完整路径(例如exampledir/exampleobject.txt)。Object完整路径中不能包含Bucket名称。
ossClient.putObject("examplebucket", "exampledir/exampleobject.txt", inputStream);
// 关闭OSSClient。
ossClient.shutdown();
