What Is Content-Type (MIME)? (Java SDK)
Multipurpose Internet Mail Extensions (MIME) type is a standard way of describing a data type. The MIME type is passed in the Content-Type header.
NOTE:
If you do not specify Content-Type when uploading an object, the SDK determines the object type based on the suffix of the specified object name and automatically assigns a value to Content-Type.
Content-Type
Content-Type indicates the type of data to send or receive and determine the form and encoding method browsers will use to display data (mainly custom client files or media files). If no content type is specified, the type will be generated based on the file name extension. If there is no extension, the content type is application/octet-stream by default.
Common Content Types
The commonly used content types are given in the table below.
|
File Name Extension |
