配置#xff1a;使用 com.qiniu.storage.Configuration 类来配置上传设置#xff0c;如指定区域#xff08;Region#xff09;和分片上传版本。上传管理器#xff1a;通过 UploadManager 类来处理文件上传。认证QiniuUtil
配置使用 com.qiniu.storage.Configuration 类来配置上传设置如指定区域Region和分片上传版本。上传管理器通过 UploadManager 类来处理文件上传。认证使用 Auth.create() 方法创建认证对象然后生成上传凭证upToken。上传使用 uploadManager.put() 方法上传文件可以上传字节数组、文件路径或输入流。错误处理捕获 QiniuException 来处理上传过程中可能出现的错误。

配置使用 OSSClientBuilder 来构建 OSS 客户端实例需要提供 endpoint、accessKeyId、accessKeySecret。上传使用 ossClient.putObject() 方法上传文件可以直接上传字节数组或输入流。错误处理捕获 OSSException 和 ClientException 来处理上传过程中可能出现的错误。资源管理在 finally 块中关闭 OSS 客户端实例。
主要区别
客户端构建七牛云使用 UploadManager 和 Configuration而阿里云使用 OSSClientBuilder。认证方式七牛云需要显式生成上传凭证upToken而阿里云的认证信息直接在 OSSClientBuilder 中提供。错误处理七牛云捕获 QiniuException阿里云捕获 OSSException 和 ClientException。资源管理阿里云在 finally 块中显式关闭 OSS 客户端而七牛云的 UploadManager 通常不需要显式关闭。
注意事项
七牛云的上传凭证upToken是临时的适用于短期的上传操作。阿里云的 OSS 客户端在不需要时应该关闭以释放资源。

}注意
七牛云 页面无法显示已上传的文件是因为bucket要设置http:// 且https:// 也是不行的
