GlideSysAttachment - Global

  • Rversion finale: Australia
  • Mis à jour 12 mars 2026
  • 10 minutes de lecture

    • 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.

    Remarque :
    This constructor does not take a parameter unless managing attachment attributes.
    Use the following methods for managing attachment attributes:
    Tableau 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

    The following example shows how to get all attributes assigned to a specified attachment.

    var attach = new GlideSysAttachment("04f48541083e2e50f877df7a115e31f3");

var result = attach.fetchAllAttributes();

while(result.next()) {
   gs.info("Key: " + result.getValue('key') + ", Value: " + result.getValue('value')); 
}

    Output:

    Key: title, Value: Add multiple attributes to an attachment
Key: author, Value: Abel Tuter
Key: category, Value: KB
Key: length, Value: 5000

    GlideSysAttachment - addAttribute(String attrKey, String attrValue)

    The following example shows how to add an attribute to a specified attachment with the key author and value Fred Luddy. The results can be viewed in the Attachment Attributes [sys_attachment_attribute] table.

    var attach = new GlideSysAttachment("04f48541083e2e50f877df7a115e31f3");
attach.addAttribute("author", "Fred Luddy");

var result = attach.fetchAttribute("author");

while(result.next()) {

    Key: author 
Value: Fred Luddy
