What is exact JSON format for posting attachment to JIRA?

[Faiza Iqbal]

I am receiving http POST response OK 200, but I see no file present on JIRA issue. From my research I can understand that it could be some problem with formData I am sending with request. Below is my code:

var newBuffer = new Buffer(req.Payload, 'base64');

var myReadableStreamBuffer = new streamBuffers.ReadableStreamBuffer({

frequency: 10, // in milliseconds.

chunkSize: 2048 // in bytes.

});

// With a buffer

myReadableStreamBuffer.put(newBuffer);

var formData = {

'file': {

'content': myReadableStreamBuffer,

'filename': req.FileName,

'mimeType': req.MimeType //mimeType from JSON

}

};

var options = {

url: 'https://comapny.atlassian.net/rest/api/2/issue/' + req.ReferenceId + '/attachments',

method: "POST",

json: true,

headers: {

'ContentType': 'multipart/form-data',

'Authorization': 'Basic ' + new Buffer(config.jira.jiraUser.userName + ':' + config.jira.jiraUser.password).toString('base64'),

'X-Atlassian-Token': 'nocheck'

},

formData: JSON.stringify(formData)

};

request(options,

function (error, response, body) {

if (error) {

errorlog.error(`Error Message : PostAttachmentToCSMS : ${error}`);

return response.statusCode;

}

else {

successlog.info(`Attachment posted for issue Key: ${req.ReferenceId} ${response.statusMessage}`);

return response.statusCode;

}

});

After spending some more time on it, I have found the correct format for formData: 

var newBuffer = new Buffer(req.Payload, 'base64');

var formData = { file: { value: newBuffer, options: { filename: req.FileName, contentType: req.MimeType } } };
