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(shù)據(jù)源，文件上傳使用本地文件作為OSS文件的數(shù)據(jù)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(wǎng)Endpoint為例。如果您希望通過與OSS同地域的其他阿里云產(chǎn)品訪問OSS，請使用內(nèi)網(wǎng)Endpoint。關(guān)于OSS支持的Region與Endpoint的對應(yīng)關(guān)系，請參見OSS訪問域名、數(shù)據(jù)中心、開放端口。
本文以從環(huán)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O(shè)SS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(quán)限。具體操作，請參見為RAM用戶授權(quán)自定義的權(quán)限策略。

流式上傳

使用流式上傳，您可以將數(shù)據(jù)流上傳到OSS文件。

說明

如果OSS文件存在，則上傳的數(shù)據(jù)會覆蓋該文件的內(nèi)容；如果OSS文件不存在，則會新建該文件。

上傳字符串
