    • The GlideSysAttachment API provides methods for handling attachments.

    Content is returned as a GlideScriptableInputStream object when getContentStream() is called. The GlideScriptableInputStream contains the actual bytes not converted into a string.

    Encryption API scope restriction

    Methods that manage encryption contexts, cryptographic modules, or encryption state are available only in the global application. These APIs are intentionally restricted because they modify platform‑level security configuration.

    GlideSysAttachment - GlideSysAttachment()

    Creates an instance of the GlideSysAttachment class.

    주:
    This constructor does not take a parameter unless managing attachment attributes.
    Use the following methods for managing attachment attributes:
    표 1. Parameters
    Name Type Description
    idAttachmentAttributes String This parameter is only used when handling attachment attributes, otherwise leave empty. Sys_id of an attachment with attributes.

    Table: Attachments [sys_attachment]

    The following script lists attachment file names for a record with two attachments.

    var attachment = new GlideSysAttachment();

var agr = attachment.getAttachments('<table_name>', '<record_sys_id>');

while(agr.next())
gs.info(agr.getValue('file_name'));

    Output:

    *** Script: filename1.txt
*** Script: filename2.txt
