Java綁定自定義域名

更新時(shí)間：
產(chǎn)品詳情
我的收藏

文件（Object）上傳至存儲(chǔ)空間（Bucket）后，OSS會(huì)自動(dòng)生成文件URL，您可以直接通過(guò)文件URL（即Bucket外網(wǎng)訪問(wèn)域名）訪問(wèn)該文件。如果您希望通過(guò)自定義域名訪問(wèn)這些Object，需要添加CNAME記錄將自定義域名綁定至Object所在的Bucket。

注意事項(xiàng)

  • 本文以華東1（杭州）外網(wǎng)Endpoint為例。如果您希望通過(guò)與OSS同地域的其他阿里云產(chǎn)品訪問(wèn)OSS，請(qǐng)使用內(nèi)網(wǎng)Endpoint。關(guān)于OSS支持的Region與Endpoint的對(duì)應(yīng)關(guān)系，請(qǐng)參見(jiàn)OSS訪問(wèn)域名、數(shù)據(jù)中心、開(kāi)放端口。

  • 本文以從環(huán)境變量讀取訪問(wèn)憑證為例。如何配置訪問(wèn)憑證，請(qǐng)參見(jiàn)Java配置訪問(wèn)憑證。

  • 本文以OSS域名新建OSSClient為例。如果您希望通過(guò)自定義域名、STS等方式新建OSSClient，請(qǐng)參見(jiàn)新建OSSClient。
