2. Plugins on OnDemand with
Remote Apps
Don Brown
Architect, Atlassian

3. Five years ago. . .

4. And now. . .
• Over 12k active, 9k paid OnDemand accounts
• 5 out of 10 add Greenhopper
• 1.5 out of 10 add Bonfire
• 1 out of 10 add Team Calendars
. . . Instances

5. The Fine Print

6. But isn‟t it just a copy?

7. Plugin Problems: Security
<% String eid = request.getParameter("eid"); %>
...
Employee ID: <%= eid %>

38. Steps to create Lucidchart app
• Establish Trust
• Register App
• Implement General Page
• Implement macro

39. Any language can be used
• Lucidchart is using PHP

40. Add Diagram (general page)
function doclist() {
if (!$this->_hasValidOAuthSignature()) {
$this->set("oauthValid", false);
return;
}
$userId = @$_REQUEST['user_id'];
$pageId = @$_REQUEST['page_id'];
$redirectURL = "https://" . $_SERVER['SERVER_NAME'] .
'/ondemand/attachDocument?page_id=' . $pageId . "&user_id=" . $userId;
$this->layout = „ondemand';
$this->set("baseUrl", $this->_getBaseURL());
$this->set("callback", urlencode($redirectURL));
}

41. Add Diagram (general page)
function doclist() {
if (!$this->_hasValidOAuthSignature()) {
$this->set("oauthValid", false);
return;
}
$userId = @$_REQUEST['user_id'];
$pageId = @$_REQUEST['page_id'];
$redirectURL = "https://" . $_SERVER['SERVER_NAME'] .
'/ondemand/attachDocument?page_id=' . $pageId . "&user_id=" . $userId;
$this->layout = „ondemand';
$this->set("baseUrl", $this->_getBaseURL());
$this->set("callback", urlencode($redirectURL));
}

42. Add Diagram (general page)
function doclist() {
if (!$this->_hasValidOAuthSignature()) {
$this->set("oauthValid", false);
return;
}
$userId = @$_REQUEST['user_id'];
$pageId = @$_REQUEST['page_id'];
$redirectURL = "https://" . $_SERVER['SERVER_NAME'] .
'/ondemand/attachDocument?page_id=' . $pageId . "&user_id=" . $userId;
$this->layout = „ondemand';
$this->set("baseUrl", $this->_getBaseURL());
$this->set("callback", urlencode($redirectURL));
}

function doclist() {
if (!$this->_hasValidOAuthSignature()) {
$this->set("oauthValid", false);
return;

$userId = @$_REQUEST['user_id'];
$pageId = @$_REQUEST['page_id'];
$redirectURL = "https://" . $_SERVER['SERVER_NAME'] .

$this->layout = „ondemand';
$this->set("baseUrl", $this->_getBaseURL());
$this->set("callback", urlencode($redirectURL));
}

44. Make API calls to attach diagram
function attachDocument() {
...
$fullUrl = $baseURL . "/rpc/xmlrpc?user_id=" . $userId;
$auth_header = $this->_getAuthHeader($fullUrl);
xmlrpc_set_type($imageBytes, "base64");
$attachmentMetaData = array("fileName"=>$attachmentName,
"contentType"=>"image/png",
"comment"=>"Imported from Lucidchart (do not deleted)");
$addAttachmentBody= xmlrpc_encode_request(
"confluence2.addAttachment",
array("", $pageId, $attachmentMetaData ,$imageBytes));
$this->_sendXMLRPCRequest($fullUrl, array(
"Content-Type: text/xml",
$auth_header),
$addAttachmentBody);
...
}

45. Make API calls to attach diagram
function attachDocument() {
...
$fullUrl = $baseURL . "/rpc/xmlrpc?user_id=" . $userId;
$auth_header = $this->_getAuthHeader($fullUrl);
xmlrpc_set_type($imageBytes, "base64");
$attachmentMetaData = array("fileName"=>$attachmentName,
"contentType"=>"image/png",
"comment"=>"Imported from Lucidchart (do not deleted)");
$addAttachmentBody= xmlrpc_encode_request(
"confluence2.addAttachment",
array("", $pageId, $attachmentMetaData ,$imageBytes));
$this->_sendXMLRPCRequest($fullUrl, array(
"Content-Type: text/xml",
$auth_header),
$addAttachmentBody);
...
}

$attachmentMetaData = array("fileName"=>$attachmentName,

$addAttachmentBody= xmlrpc_encode_request(

array("", $pageId, $attachmentMetaData ,$imageBytes));
$this->_sendXMLRPCRequest($fullUrl, array(

$addAttachmentBody);
...
}

$fullUrl = $baseURL . "/rpc/xmlrpc?user_id=" . $userId;
$auth_header = $this->_getAuthHeader($fullUrl);
xmlrpc_set_type($imageBytes, "base64");
$attachmentMetaData = array("fileName"=>$attachmentName,

...
}

48. Steps to create Lucidchart app
• Establish Trust
• Register App
• Implement General Page
• Implement macro

49. Macro
• Receive macro params
• Return HTML
• Will be cached (caching header can be returned)
• No CSS, inline styles or JavaScript

50. Macro : Receive macro params
function macro() {
$userId = $_REQUEST['user_id'];
$name = $_REQUEST['name'];
$pageId = $_REQUEST['pageId'];
$docId = $_REQUEST['id'];
$width= $_REQUEST['width'];
$height = $_REQUEST['height'];
$align = $_REQUEST['align'];
$outputType = $_REQUEST['ctx_output_type'];
...

51. Macro: Return HTML
<div style="float: “ . $align . "; margin: 0 auto; width: " . (intVal($width)
+ 2) . "px;">
<img
src=“$pageAttachment['url']”
width=“$width”
height=“$height”/>
<div style="text-align: center">
<a href='sign://"$host/editDocument/$docId?attachment= $name'>Edit
Diagram</a> |
<a href=$baseUrl/plugins/servlet/remoteapps/lucidchart-
app/lucidAppRemove?page_id=$pageId&doc_id=$docId&attachment=$name'>Remove
Diagram</a>
</div>
</div>
