How can I make zip file?
Hello,
I would like to create a custom action to download record attachments as a zip in LightningExperience.
I created a controller and Visualforce to download attachments obtained using zippex https://github.com/pdalcol/Zippex.
But even small files will give errors.
Error: System.LimitException: Apex CPU time limit exceeded
I researched myself and found that using @future can avoid it, but I don't know what code to write.
I do not have enough knowledge as a developer.
Please Help me.

public class ImageZipController {
public final ParentObject__c parent {get; set;}

this.order = (order__c)stdController.getRecord();
}
public PageReference downloadAttachments(){
orderId = order.Id;
String objectId = parentObjId;
String docName = 'test.zip';
List<Attachment> attachments = [SELECT Name, Body FROM Attachment WHERE ParentId = :objectId];
System.debug('>>> attachments ' + attachments.size());
Zippex sampleZip = new Zippex();
for(Attachment file : attachments) {
sampleZip.addFile('folder/' + file.Name, file.Body, null);
}
try{
Document doc = new Document();
doc.FolderId = UserInfo.getUserId();
doc.Name = docName;
doc.Body = sampleZip.getZipArchive();
insert doc;
System.debug('>>> doc ' + doc.Id);
return new PageReference('/servlet/servlet.FileDownload?file=' + doc.Id);
} catch ( Exception ex ) {
System.debug('>>> ERROR ' + ex);
}
return null;
}
}
