Java簡單上傳

更新時間：
產品詳情
我的收藏

簡單上傳是指通過PutObject方法上傳單個文件（Object）。簡單上傳包括流式上傳和文件上傳，流式上傳使用InputStream作為OSS文件的數據源，文件上傳使用本地文件作為OSS文件的數據源。本文介紹如何使用流式上傳和文件上傳方式上傳文件。

注意事項

  • 本文以華東1（杭州）外網Endpoint為例。如果您希望通過與OSS同地域的其他阿里云產品訪問OSS，請使用內網Endpoint。關于OSS支持的Region與Endpoint的對應關系，請參見OSS訪問域名、數據中心、開放端口。

  • 本文以從環境變量讀取訪問憑證為例。如何配置訪問憑證，請參見Java配置訪問憑證。

  • 本文以OSS域名新建OSSClient為例。如果您希望通過自定義域名、STS等方式新建OSSClient，請參見新建OSSClient。

  • 要簡單上傳，您必須有oss:PutObject權限。具體操作，請參見為RAM用戶授權自定義的權限策略。

流式上傳

使用流式上傳，您可以將數據流上傳到OSS文件。

說明

如果OSS文件存在，則上傳的數據會覆蓋該文件的內容；如果OSS文件不存在，則會新建該文件。

上傳字符串

以下代碼用于將字符串上傳到目標存儲空間examplebucket中exampledir目錄下的exampleobject.txt文件。
