I'm trying to work on a chat bot for Hangouts that runs a function every day and sends a message. I started with the template on the Google Developers site, but I'm getting an 404 Truncated server response error while fetching the URL.
Error:
Truncated server response: <h1>Not Found</h1> <h2>Error 404</h2>
Here is the code:
function onTrigger() {
var spaceIds = PropertiesService.getScriptProperties()
.getKeys();
var message = { 'text': 'Hi! It\'s now ' + (new Date()) };
for (var i = 0; i < spaceIds.length; ++i) {
postMessage(spaceIds[i], message);
}
}
var SCOPE = 'https://www.googleapis.com/auth/chat.bot';
// The values below are copied from the JSON file downloaded upon
// service account creation.
var SERVICE_ACCOUNT_PRIVATE_KEY = "-----BEGIN PRIVATE KEY---- bla bla bla---END PRIVATE KEY-----\n";
var SERVICE_ACCOUNT_EMAIL = "blablabla";
//key and email deleted here for safety reasons.
// Posts a message into the given space ID via the API, using
// service account authentication.
function postMessage(spaceId, message) {
var service = OAuth2.createService('chat')
.setTokenUrl('https://accounts.google.com/o/oauth2/token')
.setPrivateKey(SERVICE_ACCOUNT_PRIVATE_KEY)
.setClientId(SERVICE_ACCOUNT_EMAIL)
.setPropertyStore(PropertiesService.getUserProperties())
.setScope(SCOPE);
if (!service.hasAccess()) {
Logger.log('Authentication error: %s', service.getLastError());
return;
}
var url = 'https://chat.googleapis.com/v1/' + spaceId + '/messages';
UrlFetchApp.fetch(url, {
method: 'post',
headers: { 'Authorization': 'Bearer ' + service.getAccessToken() },
contentType: 'application/json',
payload: JSON.stringify(message),
});event.type == "ADDED_TO_SPACE"
}
Any help will be appreciated.
Thanks in advance. Marcos
