How can we make large number of callouts?

Hi,
We have onetime files (roughly around 100,000) migration from legacy system to Salesforce. The migration can be done by an expert and after complete migration we need to move Attachments from Salesforce to Box (external file system, due to storage limits on our Salesforce account) using REST api calls and from the response I'm creating Custom attachment object and storing box file metadata (like file name and file id). When it comes to one or two attachments per transaction then it fine but How can we send these 100,000 attachments to Box? I see some Apex limitations on callouts but I need an idea on how to send these? Is there any approach to split these into chunks and make calls?

Please advice. 

Thanks,

How can we cover the Test on trigger after delete?

Hi,
I have a simple trigger that calls on delete, and internally it calls REST callout to delete external file. When I write the test code, the code covered on callout piec only but still the trigger is showing 0% coverage.

Trigger Code: 
trigger BoxDeleteTrigger on BoxAttachment__c (after delete) {
    if(trigger.isdelete){
        ID attachmentID = Trigger.old[0].Id;
        String BoxFileID= Trigger.old[0].BoxFileID__c;
        BoxController.fileDeleteFromBox(BoxFileID);
    }
}

Callout code: 
public class BoxController {

@future (callout=true)
    global static void fileDeleteFromBox(String fileId){
        try{
            HttpRequest req=new HttpRequest();
        req.setEndpoint(endPointURL);
        if (body!=''){
        	req.setHeader('Content-Type', 'application/x-www-form-urlencoded');
        	req.setBody(body);
        }
        req.setMethod(method);
        req.setTimeout(60000); // timeout in milliseconds
        response=new Http().send(req);
        }catch(Exception e){
            System.debug(' Cannot fileDeleteFromBox: actual error is '+e.getMessage());
        }
    }
}

Test Code: 
@isTest
global class BoxDeleteTriggerTest {
	@isTest
    static void boxFileDeleteTest(){
        String boxFileID='1123124552';
        Test.setMock(HttpCalloutMock.class, new BoxControllerMockImpl(204,'Success','',null));
        Test.startTest();
        BoxController.fileDeleteFromBox(boxFileID);
        Test.stopTest();
        System.assertEquals(204, BoxController.response.getStatusCode());
    }
}
Please help on coverage for BoxDeleteTrigger

How to get a file URL from secured amazon s3 using REST API?

Hi,
We need to show around 100 photos on a page, the photos are in secured S3 bucket. and each photo retrieved by photoid. I tried to get blog and convert into string to display on  page but the page is taking around 30 secs to load all photos. Is there a way to get photo URL rather getting blob and Ill put that on page (I use iframe to show photo)?

Here is the apex code I'm using for REST api call to get photo by id. 
public void getPhotofromAWS(String photoid){
        
        HttpRequest req = new HttpRequest();
        req.setMethod('GET');
        //String endpoint ='https://xxxxxx.s3.amazonaws.com/photo';
        String bucketName = 'xxxxxx';
        String fileName = photoid+'.jpg';
        String formattedDateString = Datetime.now().format('EEE,   dd MMM yyyy HH:mm:ss z');
        req.setHeader('Date', formattedDateString);
        String stringToSign = 'GET\n\n\n'+formattedDateString+'\n/'+bucketName +'/photo/'+filename;
        Blob mac = Crypto.generateMac('HMACSHA1', blob.valueof(stringToSign),blob.valueof('aaaaaaaaaAxxxxxxxxxsssssAAAAAAa'));
        String sig = EncodingUtil.base64Encode(mac);
        String auth = 'AWS' + ' ' + 'AAAAAAAAAAAAAAA' + ':' + sig;
        req.setHeader('Authorization',auth);
        String endpointBase = 'http://' + bucketName + '.s3.amazonaws.com/photo/' + filename;
        system.debug(' guid '+guid);
        req.setEndpoint(endpointBase );
        Http http = new Http();
        HTTPResponse res = http.send(req);
        //photoString = res.getBody();
        photoString='data:'+res.getHeader('Content-Type')+';base64,'+EncodingUtil.base64Encode(res.getBodyAsBlob());
 
    }

This is occurig when trying to decoding ( base64Decode ) from String blob before Rest API call, please check the code 
String bodyEncoded = EncodingUtil.base64Encode(fileBody);
Blob bodyBlob = null;
String last4Bytes = bodyEncoded.substring(bodyEncoded.length()-4,bodyEncoded.length());
// GW: replacement section to get rid of padding without corrupting data
if(last4Bytes.endsWith('==')) {
    last4Bytes = last4Bytes.substring(0,2) + '0K';
    bodyEncoded = bodyEncoded.substring(0,bodyEncoded.length()-4) + last4Bytes;
    String footerEncoded = EncodingUtil.base64Encode(Blob.valueOf(footer));
    bodyBlob = EncodingUtil.base64Decode(headerEncoded+bodyEncoded+footerEncoded); //Here its failing
}else if(last4Bytes.endsWith('=')){

}
Error is triggering at "bodyBlob = EncodingUtil.base64Decode(headerEncoded+bodyEncoded+footerEncoded);" this line.
Please advice how can we ignore the size of the file? We may have to upload 10MB files sometimes, please advice

Uploading large files failing (5mb+)

Hi,
We are replacing native functionality of Attachments to upload files to "Box"external storage using Rest API, I was able to upload small files upto 5MB but when trying to upload big files I get the error in Apex code (not even going to box)  
System.StringException: String length exceeds maximum: 6000000
This is occurig when trying to decoding ( base64Decode ) from String blob before Rest API call, please check the code. 
String bodyEncoded = EncodingUtil.base64Encode(fileBody);
Blob bodyBlob = null;
String last4Bytes = bodyEncoded.substring(bodyEncoded.length()-4,bodyEncoded.length());
// GW: replacement section to get rid of padding without corrupting data
if(last4Bytes.endsWith('==')) {
    last4Bytes = last4Bytes.substring(0,2) + '0K';
    bodyEncoded = bodyEncoded.substring(0,bodyEncoded.length()-4) + last4Bytes;
    String footerEncoded = EncodingUtil.base64Encode(Blob.valueOf(footer));
    bodyBlob = EncodingUtil.base64Decode(headerEncoded+bodyEncoded+footerEncoded); //Here its failing
}else if(last4Bytes.endsWith('=')){

Change sets error on Duplicate rules

Hi,

I was trying to upload Dupicate Rules along with Correspondng Matching rules from partial SB to Full SB but got the following error while validating the Inbound change sets. basically the error is related to the duplicate rules order on a custom object. I wrote 3 rules on that object but no clue how to set the order.
  
AQAddress__c.Address_Duplicate_Matching_Rule	Duplicate Rule	0	0	SortOrder must be in sequential order from 1.

How can we make large number of callouts?

Hi,
We have onetime files (roughly around 100,000) migration from legacy system to Salesforce. The migration can be done by an expert and after complete migration we need to move Attachments from Salesforce to Box (external file system, due to storage limits on our Salesforce account) using REST api calls and from the response I'm creating Custom attachment object and storing box file metadata (like file name and file id). When it comes to one or two attachments per transaction then it fine but How can we send these 100,000 attachments to Box? I see some Apex limitations on callouts but I need an idea on how to send these? Is there any approach to split these into chunks and make calls?

Please advice. 

Thanks,

How can we cover the Test on trigger after delete?

Hi,
I have a simple trigger that calls on delete, and internally it calls REST callout to delete external file. When I write the test code, the code covered on callout piec only but still the trigger is showing 0% coverage.

Trigger Code: 
trigger BoxDeleteTrigger on BoxAttachment__c (after delete) {
    if(trigger.isdelete){
        ID attachmentID = Trigger.old[0].Id;
        String BoxFileID= Trigger.old[0].BoxFileID__c;
        BoxController.fileDeleteFromBox(BoxFileID);
    }
}

Callout code: 
public class BoxController {

@future (callout=true)
    global static void fileDeleteFromBox(String fileId){
        try{
            HttpRequest req=new HttpRequest();
        req.setEndpoint(endPointURL);
        if (body!=''){
        	req.setHeader('Content-Type', 'application/x-www-form-urlencoded');
        	req.setBody(body);
        }
        req.setMethod(method);
        req.setTimeout(60000); // timeout in milliseconds
        response=new Http().send(req);
        }catch(Exception e){
            System.debug(' Cannot fileDeleteFromBox: actual error is '+e.getMessage());
        }
    }
}

Test Code: 
@isTest
global class BoxDeleteTriggerTest {
	@isTest
    static void boxFileDeleteTest(){
        String boxFileID='1123124552';
        Test.setMock(HttpCalloutMock.class, new BoxControllerMockImpl(204,'Success','',null));
        Test.startTest();
        BoxController.fileDeleteFromBox(boxFileID);
        Test.stopTest();
        System.assertEquals(204, BoxController.response.getStatusCode());
    }
}
Please help on coverage for BoxDeleteTrigger

Testing Visualforce cotrollers with HTTP callouts help

Please find any clue on that issue and let me know. please look at this steps I followed

Step1: created box app for client id and client secret
2: got Access Token and Refresh Token using postman service
3. used these in following Apex code.
4. when I tried to Attach a file I get the following error.

Apex Method called remote from Javascript problem

Hi everyone,

 

So I am getting the hand of apex methods being called remote from javascript.

Of course I am having some issues. I have put a temparary method in my apex class that I want to be called from some javascript in the visual force page.

However it seems that I have a bug somewhere because the javascript does not run. 

I have been looking at this code for i'm guessing a couple of hours and can't see what is wrong. 

Maybe someone on here can give me a hand.

 

Visualforce Javascript / code:

 

<apex:page controller="AMManagementController">
<script>
        function switchMenu(obj,obj1,obj2) 
        {
            var el = document.getElementById(obj);                                       
            if ( el.style.display != 'none' ) {
            el.style.display = 'none';
            }
            else {
            el.style.display = '';
            }
            var e2 = document.getElementById(obj1);                                       
            if ( e2.style.display != 'none' ) {
            e2.style.display = 'none';
            }
            else {
            e2.style.display = '';
            }
             var e3 = document.getElementById(obj2);                                       
            if ( e2.style.display != 'none' ) {
            e3.style.display = 'none';
            }
            else {
            e3.style.display = '';
            }

        }
        
        function CheckUpdate(){
            AMManagementController.UpdateCheck('Update',function(result, event){
                if(result == false)
                    alert('Are you sure you want to do this?');
