請求者付費模式是指由請求者支付讀取存儲空間（Bucket）內數據時產生的流量費用和請求費用，而Bucket擁有者僅支付存儲費用。當您希望共享數據，但又不希望產生流量費用和請求費用時，您可以開啟此功能。

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。
要設置請求者付費模式，您必須有oss:PutBucketRequestPayment權限；要獲取請求者付費模式，您必須有oss:GetBucketRequestPayment權限。具體操作，請參見為RAM用戶授權自定義的權限策略。

設置請求者付費模式

第三方付費訪問Object

第三方操作Object時需在HTTP Header中攜帶x-oss-request-payer:requester參數，否則會報錯。

以下代碼以PutObject、GetObject和DeleteObject為例，用于指定第三方付費訪問Object。其他用于指定第三方付費的Object讀寫操作接口設置方法類似。

以下代碼用于設置第三方付費訪問Object。
