Convert REST response to Base64

[iqbalkhokhar]

Hi,

I am trying to fetch JIRA attachment through JIRA rest API and JIRA rest API provide me url (/secure/attachment/{attachment-id}/{attachment-name})

of the content. Further, I am trying to get attachment itself as below.

// code

var targetInstanceURL =   "https://jira.****.com/secure/attachment/261255/";  

var targetUserID = "username";  

var targetUserPassword = "pass";  

var sa = new GlideSysAttachment();

var StringUtil = GlideStringUtil();

sendAttachments();

function sendAttachments() {  

                                              var attachmentMessage = new sn_ws.RESTMessageV2();  

                      attachmentMessage.setHttpMethod("get");  

                      attachmentMessage.setBasicAuth(targetUserID, targetUserPassword);  

                      attachmentMessage.setEndpoint(targetInstanceURL);  

                      var response = attachmentMessage.execute();  

                      var responseBody = response.getBody();  

                      var httpStatus = response.getStatusCode();

                    gs.log(responseBody);

var base64string = GlideStringUtil.base64Encode(responseBody);

gs.log("2 " + base64string );

.

.

.

}

Response Header:

Content-Disposition: inline; filename*=UTF-8''tets.jpg;

Content-Length: 2781

Content-Type: image/jpeg

OUTPUT:

gs.log(responseBody) is something like ���� JFIF     xx��C                                                                            

gs.log("2 " + base64string ) is something like   77+977+977+977+9ABBKRklGAAEBAQB4AHgAAO+/ve+/vQBDAAIBAQIBAQICAgICAgICAwUDAwMDAw

Cases:

1. For text file my code is working fine and I am able to add attachment in service now table.

2. For image and pdf my code is working but saved file is showing as corrupt file.

Problem:

As per my understanding for image response conversion to base64 is not correct and GlideStringUtil.base64Encode() methode is not encoding image/pdf response to base64.

Question:

1. How to convert image/pdf response to base64 or ByteArray?

2. Any other approach to store attachment in service now from JIRA?

Thanks in advanced.

Regards,

Iqbal

Thanks you all for response.

I am able to save attachment through saveResponseBodyAsAttachment.

//code

var targetInstanceURL = endpoint;

var targetUserID = username;

var targetUserPassword =password;

var sa = new GlideSysAttachment();

var attachmentMessage = new sn_ws.RESTMessageV2();

attachmentMessage.setHttpMethod("get");

//Mid server if you want to run it thorugh mid server

var midServer = gs.getProperty("midServerName", "");

if(midServer){

attachmentMessage.setMIDServer(midServer);

}

//

attachmentMessage.setBasicAuth(targetUserID, targetUserPassword);

attachmentMessage.setEndpoint(targetInstanceURL);

attachmentMessage.saveResponseBodyAsAttachment("incident", incSysId,fileName,fileType);

var response = attachmentMessage.execute();

var httpStatus = response.getStatusCode();

var newAttachmentSysId = response.getResponseAttachmentSysid();

Hi Ankur,

We are receiving the responseBody in Binary format. We want the responseBody to be attached as a pdf file to a current record. So using below code.

var base64string = GlideStringUtil.base64Encode(responseBody);

var attCreator = new GlideRecord('ecc_queue');
     attCreator.agent = "AttachmentCreator";
     attCreator.topic = "AttachmentCreator";
     attCreator.name =   "test1.pdf" + ":" + 'pdf';
     attCreator.source = tablename+":"+recordsys_id;

attCreator.payload = base64string;
     attCreator.insert();

But it is attaching an empty file. when I try below code:

var value = GlideStringUtil.base64Decode(responseBody);

var attCreator = new GlideRecord('ecc_queue');
     attCreator.agent = "AttachmentCreator";
     attCreator.topic = "AttachmentCreator";
     attCreator.name =   "test1.pdf" + ":" + 'pdf';
     attCreator.source = tablename+":"+recordsys_id;

attCreator.payload = base64string;
     attCreator.insert();

This is returning corrupted file and unable to open it. Could you please suggest an alternative way to convert binary format response into an attachment pdf.

Thanks.
