Create Freshdesk Ticket with attachment from Google App Script by UrlFetchApp - google-apps-script

Question

I try to use google apps script to create ticket with attachments via freshdesk API.
Freshdesk have google app script sample code here: https://github.com/freshdesk/fresh-samples/tree/master/google_script , but without attachment demo.
I tried the following code, but it seems always return error by /helpdesk/tickets.json api.
how to post a attachment in google app script with UrlFetchApp right?
function createFreshdeskTicketWithAttachments() {
var API_KEY = PropertiesService.getScriptProperties().getProperty('FreshDeskApiKey')
if (!API_KEY) throw new Error('FreshDeskApiKey not found in script properties.')
var ENDPOINT = Utilities.formatString('https://%s.freshdesk.com', 'zixia')
var headers = {
'Authorization': 'Basic ' + Utilities.base64Encode(API_KEY + ':X')
, 'Content-type': 'application/json'
//'Content-type': 'multipart/form-data'
};
var response = UrlFetchApp.fetch("https://circleci.com/gh/AKAMobi/ucapp/tree/master.svg?style=svg")
var fileBlob = response.getBlob()
Logger.log("%s:%s"
, response.getResponseCode()
, fileBlob.getContentType()
)
var payload = {
helpdesk_ticket: {
description: 'TEST 4'
, subject: "TEST 4"
, email: "test#test.com"
, priority: 1
, status: 2
, attachments: { '': [ { resource: fileBlob } ] }
}
}
//Adds the extensions that are needed to post a new ticket to the end of the url
var url = ENDPOINT + '/helpdesk/tickets.json';
var options = {
'method': 'post',
'headers': headers,
'payload': JSON.stringify(payload),
// 'payload': payload,
muteHttpExceptions: true
};
var response = UrlFetchApp.fetch(url, options);
Logger.log('resp: %s, %s'
, response.getResponseCode()
, response.getContentText()
)
}

after use debug with nc:
nc -l 211.99.222.55 3333
I found payload array should write like this:
var payload = {
'helpdesk_ticket[description]': 'test jjjj'
, 'helpdesk_ticket[subject]': 'test jj'
, 'helpdesk_ticket[email]': 'test#test.com'
, 'helpdesk_ticket[attachments][][resource]': fileBlob1
, 'helpdesk_ticket[attachments][][resource]': fileBlob2
}
but fileBlob2 will not post to server, because the key of array is duplicated. I tried to change 'helpdesk_ticket[attachments][][resource]' to 'helpdesk_ticket[attachments][1][resource]' but it did not work.
so here's a workable version, which only support single attachment:
function createTicket() {
var API_KEY = PropertiesService.getScriptProperties().getProperty('FreshDeskApiKey')
if (!API_KEY) throw new Error('FreshDeskApiKey not found in script properties.')
var ENDPOINT = Utilities.formatString('https://%s.freshdesk.com', 'zixia')
var headers = {
'Authorization': 'Basic ' + Utilities.base64Encode(API_KEY + ':X')
}
var response = UrlFetchApp.fetch("https://circleci.com/gh/AKAMobi/ucapp/tree/master.svg?style=svg")
var fileBlob1 = response.getBlob()
var fileBlob2 = UrlFetchApp
.fetch("http://imgcache.qq.com/open_proj/proj_qcloud_v2/qcloud_2015/css/img/global/internet-plus.png")
.getBlob()
var payload = {
'helpdesk_ticket[description]': 'test jjjj'
, 'helpdesk_ticket[subject]': 'test jj'
, 'helpdesk_ticket[email]': 'test#test.com'
, 'helpdesk_ticket[attachments][][resource]': fileBlob1
, 'helpdesk_ticket[attachments][][resource]': fileBlob2
}
//
// for (var i=0; i<attachments.length; i++) {
// payload['helpdesk_ticket[attachments][][resource]'] = attachments[i]
// }
//
// for (var k in payload) {
// Logger.log('%s = %s', k, payload[k])
// }
var options = {
'method': 'post'
, 'headers': headers
, 'payload': payload
, muteHttpExceptions: true
}
var url = ENDPOINT + '/helpdesk/tickets.json'
// url = 'http://211.99.222.55:3333'
var response = UrlFetchApp.fetch(url, options)
Logger.log('resp: %s, %s'
, response.getResponseCode()
, response.getContentText()
)
}

UPDATE Jan 20th, 2016
I wrote a library named GasFreshdesk for freshdesk v2 api in gas, which is very easy to use(with attachments support):
var MyFreshdesk = new GasFreshdesk('https://domain.freshdesk.com', 'TOKEN')
var ticket = new MyFreshdesk.Ticket({
description:'A description'
, subject: 'A subject'
, email: 'you#example.com'
, attachments: [
Utilities.newBlob('TEST DATA').setName('test-data.dat')
, Utilities.newBlob('TEST DATA2').setName('test-data2.dat')
]
})
ticket.assign(9000658396)
ticket.note({
body: 'Hi tom, Still Angry'
, private: true
, attachments: [
Utilities.newBlob('TEST DATA').setName('test-data.dat')
, Utilities.newBlob('TEST DATA2').setName('test-data2.dat')
]
})
ticket.reply({
body: 'Hi tom, Still Angry'
, cc_emails: ['you#example.com']
, attachments: [
Utilities.newBlob('TEST DATA').setName('test-data.dat')
, Utilities.newBlob('TEST DATA2').setName('test-data2.dat')
]
})
ticket.setPriority(2)
ticket.setStatus(2)
ticket.del()
ticket.restore()
Logger.log('ticket #' + ticket.getId() + ' was set!')

OLD POST:
finnaly, google apps script could attach multi attachments to new ticket on freshdesk by UrlFetchApp.fetch, with a hand made 'multipart' param generator helper function by myself.
put attachments in another array payload:
var payload = [
['helpdesk_ticket[description]', 'test jjjj']
, ['helpdesk_ticket[subject]', 'test jj']
, ['helpdesk_ticket[email]', 'test#test.com']
, ['helpdesk_ticket[attachments][][resource]', fileBlob2]
, ['helpdesk_ticket[attachments][][resource]', fileBlob1]
]
use makeMultipartBody function to generate a requestBody:
var multipartBody = makeMultipartBody(payload)
full code here:
function createTicket2() {
var API_KEY = PropertiesService.getScriptProperties().getProperty('FreshDeskApiKey')
if (!API_KEY) throw new Error('FreshDeskApiKey not found in script properties.')
var ENDPOINT = Utilities.formatString('https://%s.freshdesk.com', 'zixia')
var headers = {
'Authorization': 'Basic ' + Utilities.base64Encode(API_KEY + ':X')
}
var response = UrlFetchApp.fetch("https://circleci.com/gh/AKAMobi/ucapp/tree/master.svg?style=svg")
var fileBlob1 = response.getBlob()
var fileBlob2 = UrlFetchApp
.fetch("http://imgcache.qq.com/open_proj/proj_qcloud_v2/qcloud_2015/css/img/global/internet-plus.png")
.getBlob()
var payload = [
['helpdesk_ticket[description]', 'test jjjj']
, ['helpdesk_ticket[subject]', 'test jj']
, ['helpdesk_ticket[email]', 'test#test.com']
, ['helpdesk_ticket[attachments][][resource]', fileBlob2]
, ['helpdesk_ticket[attachments][][resource]', fileBlob1]
]
var boundary = '-----CUTHEREelH7faHNSXWNi72OTh08zH29D28Zhr3Rif3oupOaDrj'
payload = makeMultipartBody(payload, boundary)
//Logger.log('payload: %s', payload)
//return
var options = {
'method': 'post'
, contentType: "multipart/form-data; boundary=" + boundary
, 'headers': headers
, 'payload': payload
, muteHttpExceptions: true
}
var url = ENDPOINT + '/helpdesk/tickets.json'
// url = 'http://211.99.222.55:3333'
var response = UrlFetchApp.fetch(url, options)
Logger.log('resp: %s, %s'
, response.getResponseCode()
, response.getContentText()
)
}
function makeMultipartBody(payload, boundary) {
var body = Utilities.newBlob('').getBytes()
Logger.log(payload)
for (var i in payload) {
var [k, v] = payload[i]
Logger.log('############ %s = %s', k, v)
if (v.toString() == 'Blob') {
// attachment
body = body.concat(
Utilities.newBlob(
'--' + boundary + '\r\n'
+ 'Content-Disposition: form-data; name="' + k + '"; filename="' + v.getName() + '"\r\n'
+ 'Content-Type: ' + v.getContentType() + '\r\n\r\n'
).getBytes())
body = body
.concat(v.getBytes())
.concat(Utilities.newBlob('\r\n').getBytes())
} else {
// string
body = body.concat(
Utilities.newBlob(
'--'+boundary+'\r\n'

).getBytes()
)
}
}
body = body.concat(Utilities.newBlob("\r\n--" + boundary + "--\r\n").getBytes())
return body
}
