ContentType Property

The content type to send for a file.

Syntax

 backblazeb2.getContentType([callback])
 backblazeb2.setContentType( contentType, [callback])

Default Value

""

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getContentType([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setContentType([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This property can be set before calling UploadFile, StartMultipartUpload, or (if the SendMetadataOnCopy configuration setting is enabled) CopyFile to have its value submitted as the file's Content-Type header value.

If this property is empty, the class will send b2/x-auto, which instructs the server to automatically determine the content type based on the file's extension (or set it to application/octet-stream if it cannot).

This property is not available at design time.
