Content-Type(MIME)用于标识发送或接收数据的类型,浏览器根据该参数来决定数据的打开方式。Content-Type多用于指定一些客户端自定义的文件,以及一些媒体文件的打开方式。
说明 如果您在上传Object时未指定Content-Type,SDK会根据指定Object名称的后缀名来判定文件类型并自动填充Content-Type。
设置Content-Type
您可以使用OSS控制台、图形化管理工具ossbrowser、阿里云SDK、命令行工具ossutil以及REST API设置Content-Type。具体步骤,请参见管理文件元信息。
重要 仅支持对单个Object设置Content-Type,不支持根据Object前缀或者后缀批量设置Content-Type。
