Download attachment with atlassian-connect-express sample


I am trying to download a Jira issue attachment using the atlassian-connect-express sample (JWT security).  The attachment is received successfully but in string format and not binary.

Trying to save jpeg attachment to file system ends up with the jpeg being corrupted and trying to do a base64 encoding crashes due to invalid characters.

Downloding the jpeg attachment url directly from browser works fine... I think he root cause is that the jpeg is coming as a string. How do I download in binary base64?


Function code below as well as two attachments. I am stuck so all help is very much appreciated...

app.get('/img', addon.checkValidToken(), function(req, res) { var httpClient = addon.httpClient(req);
httpClient.get({ "headers": { "Content-Type": "image/jpeg", "Accept": "image/jpeg" }, "url": "" //"url": "rest/api/2/attachment/10002"
}, function(err, response, body) { if (err) { console.log(response.statusCode + ": " + err); res.send("Error: " + response.statusCode + ": " + err); } else { console.log('error:', err); // Print the error if one occurred console.log('statusCode:', response && response.statusCode); // Print the response status code
//Enabling this one crash. Probably because not valid characters - only characters in the range from U+0000 to U+00FF, each representing a binary byte with values 0x00 to 0xFF //var encodedData = base64.encode(body);
fs.writeFile("tmp/test.jpeg", body, function(err) { if (err) { console.log(err); } else { console.log("The file was saved!"); res.send(body); } });

} } ); });
