Error sending mails on Google App Engine with PHP - google-app-engine

I have Lumen running on a Google App Engine instance and everything is great, except sending mail. The standard PHP mail() returns false no matter what I try and I can't find errors in the log.
/**
* Deliver an email
*
* #param string $to_email
* #param string $body
* #param string $subject
*
* #return bool
*/
static public function send($to_email, $body, $subject)
{
$headers = 'From: myemail#gmail.com' . "\r\n" .
'Reply-To: myemail+punkr#gmail.com' . "\r\n" .
'X-Mailer: Punkr/1.0';
return mail($to_email, $subject, $body, $headers);
}
Any suggestions?

Your send mail not working could be because of different reasons:
The sender's email ID should be added as an owner in the AppEngine project or use service account ID as the sender. Documentation
If above doesn't work for you, you can try an alternative approach.
use google\appengine\api\mail\Message;
try {
$message = new Message();
$message->setSender('from#example.com');
$message->addTo('to#example.com');
$message->setSubject('Example email');
$message->setTextBody('Hello, world!');
$message->send();
echo 'Mail Sent';
} catch (InvalidArgumentException $e) {
echo 'There was an error';
}
Hope this answers your question!!!!!

Gmail (for business) API doesn't allow to send email from Alias?

I want to email my customers using different "roles" (e.g. info# , customer-support#, tech-support#, no-reply#).
I've tried 2 approaches:
Multiple "users"/accounts in my Gmail for business application.
Single gmail
account with multiple aliases.
I started by setting up a Service Account with global delegation for my Gmail for Business application.
To test that it works, I've set up 2 users: lev#mydomain.com and root#mydomain.com. Indeed, I can successfully send email both from lev# and root#.
However, when I tried adding 5 distinct user accounts for my application, Gmail got paranoid of bots/abuse and asked me to prove that all the accounts are "human" including setting up passwords, signing in and SMS-text validation via phone. Moreover, they require different phones for different accounts to prove it's a different person. So the setup of the accounts becomes a major issue.
I also want to avoid creating multiple accounts since I'm paying for each one, and since semantically, all the roles are just a single account. So aliases seem like a better idea.
The problem is that when I'm trying to send email and set the "from" field to the alias (e.g. from:no-reply#mydomain.com), I'm getting the following exception:
Exception in thread "main" com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden
{
"code" : 403,
"errors" : [ {
"domain" : "global",
"message" : "Delegation denied for root#mydomain.com",
"reason" : "forbidden"
} ],
"message" : "Delegation denied for root#mydomain.com"
}
Anyone faced and solved this issue?
The authentication/credential code is as follows:
/*
* Set up a hashmap HashMap<String, Gmail> gmailServiceByAccount where
* gmailServiceByAccount.get(emailAccount) contains an authorized Gmail service
*/
private void prepareService(String emailAccount) throws Exception {
if (gmailServiceByAccount.containsKey(emailAccount)) {
return;
}
HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
JsonFactory jsonFactory = JacksonFactory.getDefaultInstance();
GoogleCredential credential = new GoogleCredential.Builder()
.setTransport(httpTransport)
.setJsonFactory(jsonFactory)
.setServiceAccountId(Config.getInstance().getProperty(Config.gmail_service_account))
.setServiceAccountPrivateKeyFromP12File(new File(Config.getInstance().getPathToGmailCredential()))
.setServiceAccountScopes(Arrays.asList(GmailScopes.GMAIL_COMPOSE))
.setServiceAccountUser(emailAccount)
.build();
gmailServiceByAccount.put(
emailAccount,
new Gmail.Builder(httpTransport, jsonFactory, credential)
.setApplicationName(Config.getInstance().getProperty(Config.google_client_api_application_name))
.build());
}
And the code which sends the email is as follows:
/**
* Send an email using the parameters provided.
*
* #param fromPersonalName : the free text description of the "from" address (e.g. "Customer Suppport" or "No Reply").
* #param fromAddress : the email address of the sender, the mailbox account (e.g. customer-support#mydomain.com).
* #param to : the email address of the recepient.
* #param subject : Subject of the email.
* #param htmlContent : (may be null) The HTML-styled body text of the email.
* #param plainTextContent : (may be null) The plain text body of the email (e.g if the customer email client does not support or disables html email).
*/
public void sendMail(String fromPersonalName, String fromAddress, String to, String subject, String htmlContent, String plainTextContent)
throws Exception {
prepareService(fromAddress);
Properties props = new Properties();
Session session = Session.getDefaultInstance(props, null);
MimeMessage email = new MimeMessage(session);
InternetAddress tAddress = new InternetAddress(to);
InternetAddress fAddress = new InternetAddress(fromAddress);
fAddress.setPersonal(fromPersonalName);
email.setFrom(fAddress);
email.addRecipient(javax.mail.Message.RecipientType.TO, tAddress);
email.setSubject(subject);
Multipart multiPart = new MimeMultipart("alternative");
if (!StringValidation.isEmpty(plainTextContent)) {
MimeBodyPart textPart = new MimeBodyPart();
textPart.setContent(plainTextContent, "text/plain");
textPart.setHeader("Content-Type", "text/plain; charset=\"UTF-8\"");
multiPart.addBodyPart(textPart);
}
if (!StringValidation.isEmpty(htmlContent)) {
MimeBodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent(htmlContent, "text/html; charset=\"UTF-8\"");
multiPart.addBodyPart(htmlPart);
}
email.setContent(multiPart);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
email.writeTo(bytes);
String encodedEmail = Base64.encodeBase64URLSafeString(bytes.toByteArray());
Message message = new Message();
message.setRaw(encodedEmail);
gmailServiceByAccount.get(fromAddress).users().messages().send(fromAddress, message).execute();
}
After additional research, it looks like the only option is to have multiple users.
The code I've posted indeed works for multiple users, but not for anything else.
I've tried multiple options including aliases and group email accounts. I'd either get "delegation denied" or "invalid grant" errors.
I've tried contacting Google For Business customer and tech support, but they don't support the API.
There's a great workaround to creating several users without having to go through phone validation. Just specify these users as "existing users" when you're signing into Google For Business initially, and activate them before you even transfer the domain.
For the account I've created without pre-existing users, I had to ask my friend's phones for phone validation.
You can now send emails using aliases as long as those aliases are defined for the user whose login credentials you're using.
This works for the Gmail for business only.
Setting up aliases to non-existent address can be tricky, so have a look at this how to set up a catch-all routing:
catchall-for-domain-aliases-in-gsuite-gmail
Just additionally to Ladi's post, it seem to be easier to setup now. Make an alias account and configure it so you can send emails (https://support.google.com/domains/answer/9437157?hl=en&ref_topic=6293345) and set the 'from' field on the message to the alias (but still use 'me' on the API call)

How to create a SalesForce 'User' with REST API?

I am trying to create a User in SFDC with REST API on Java Client.
Please see my code below and help me to understand why I am getting the error message below:
HTTP Status 400 ::
{
errorCode: "NOT_FOUND"
message: "The requested resource does not exist"
}
CODE:
HttpClient httpClient = new HttpClient();
JSONObject user = new JSONObject();
String userId = null;
try{
user.put("Username", "email#domain.com");
user.put("Alias", "DemoAPI");
user.put("ProfileId", "00e90000000fKXB");
user.put("Email", "email123456#domain.com");
user.put("EmailEncodingKey", "ISO-8859-1");
user.put("LastName", "REST API Test");
user.put("LanguageLocaleKey", "pt_BR");
user.put("LocaleSidKey", "pt_BR");
user.put("TimeZoneSidKey", "America/Sao_Paulo");
PostMethod post = new PostMethod( instanceURL + "/services/data/v29.0/sobjects/User");
post.setRequestHeader("Authorization", "OAuth " + accessToken);
post.setRequestEntity(new StringRequestEntity(user.toString(), "application/json", null));
httpClient.executeMethod(post);
}catch(Exception e){}
I used the Chrome Postman plugin to POST the following:
Note that the resource URL was set to: (I'm assuming you are on AP1 based the the pod identifier in the ProfileId).
https://na5.salesforce.com/services/data/v29.0/sobjects/User
I got the response:
[
{
"message": "Duplicate Username.<br>The username already exists in this or another Salesforce organization. Usernames must be unique across all Salesforce organizations. To resolve, use a different username (it doesn't need to match the user's email address). ",
"errorCode": "DUPLICATE_USERNAME",
"fields": [
"Username"
]
}
]
Which is fine for testing purposes. It would have probably worked with a different username and free licenses.
Please confirm that your PostMethod URL is set to:
https://ap1.salesforce.com/services/data/v29.0/sobjects/User
In particular, check that there is no trailing slash on instanceURL.

Unable to download a document from google cloud storage

I am able to upload a document and download the document from google cloud storage for signed url using httpclient in java.But,when i put the same signed url in browser i am unable to download document for the link.I am getting following error
The request signature we calculated does not match the signature you
provided. Check your Google secret key and signing method.`
But when i mark check shared publicly check box in storage browser i am able to download from the generated signed url.But i want to allow a user to download a document from the browser without marking it as shared publicly.
.
I want to get confirm on some confusing part like
For document to get accessible by user who does not have google account after creating a signed url also i have to check shared publicly check box in storage browser?
But i think if the url is signed then it should not be check for shared publicly checkbox and user who does not have google account can access the document?But in my case it is not happening .According to link
https://developers.google.com/storage/docs/accesscontrol#About-CanonicalExtensionHeaders
it talks about Canonicalized_Extension_Headers .So i put in my request header
request.addHeader("x-goog-acl","public-read");
This is my code
// construct URL
String url = "https://storage.googleapis.com/" + bucket + filename +
"?GoogleAccessId=" + GOOGLE_ACCESS_ID +
"&Expires=" + expiration +
"&Signature=" + URLEncoder.encode(signature, "UTF-8");
System.out.println(url);
HttpClient client = new DefaultHttpClient();
HttpPut request = new HttpPut(url);
request.addHeader("Content-Type", contentType);
request.addHeader("x-goog-acl","public-read");// when i put this i get error
request.addHeader("Authorization","OAuth 1/zVNpoQNsOSxZKqOZgckhpQ");
request.setEntity(new ByteArrayEntity(data));
HttpResponse response = client.execute(request);
When i put request.addHeader("x-goog-acl","public-read");i get error
HTTP/1.1 403 Forbidden error .
.But when i remove this line it is uploaded successfully .It seems like i need to set
request.addHeader("x-goog-acl","public-read") to make it publicly accessible but on putting this on my code i am getting error.
.Any suggestion Please?
Finally Solved it.
To run singed url from browser you have to set HTTP header . In https://developers.google.com/storage/docs/accesscontrol#Construct-the-String
Content_Type Optional. If you provide this value the client (browser) must provide this HTTP header set to the same value.There is a word most.
So if you are providing Content_Type for sign string you must provide same Content_Type in browser http header.When i set Content_Type in browser header this error finally solved
this works for me:
set_include_path("../src/" . PATH_SEPARATOR . get_include_path());
require_once 'Google/Client.php';
function signed_storageURL($filename, $bucket, $p12_certificate_path, $access_id, $method = 'GET', $duration = 3600 )
{
$expires = time( ) + $duration*60;
$content_type = ($method == 'PUT') ? 'application/x-www-form-urlencoded' : '';
$to_sign = ($method."\n"."\n".$content_type."\n".$expires."\n".'/'.$bucket.'/'.$filename);
$signature = '';
$signer = new Google_Signer_P12(file_get_contents($p12_certificate_path), 'notasecret');
$signature = $signer->sign($to_sign);
$signature = urlencode( base64_encode( $signature ) );
return ('https://'.$bucket.'.commondatastorage.googleapis.com/'.$filename.'?GoogleAccessId='.$access_id.'&Expires='.$expires.'&Signature='.$signature);
}
$url = signed_storageURL(rawurlencode("áéíóú espaço & test - =.jpg"),'mybucket', 'mykey.p12','myaccount#developer.gserviceaccount.com');
echo ''.$url.'';

Batch fetching messages performance

I need to get the last 100 messages in the INBOX (headers only). For that I'm currently using the IMAP extension to search and then fetch the messages. This is done with two requests (SEARCH and then UID FETCH).
What's the Gmail API equivalent to fetching multiple messages in one request?
All I could find is a batch API, which seems way more cumbersome (composing a long list of messages:get requests wrapped in plain HTTP code).
It's pretty much the same in the Gmail API as in IMAP. Two requests: first is messages.list to get the message ids. Then a (batched) message.get to retrieve the ones you want. Depending on what language you're using the client libraries may help with the batch request construction.
A batch request is a single standard HTTP request containing multiple Google Cloud Storage JSON API calls, using the multipart/mixed content type. Within that main HTTP request, each of the parts contains a nested HTTP request.
From: https://developers.google.com/storage/docs/json_api/v1/how-tos/batch
It's really not that hard, took me about an hour to figure it out in python even without the python client libraries (just using httplib and mimelib).
Here's a partial code snippet of doing it, again with direct python. Hopefully it makes it clear that's there's not too much involved:
msg_ids = [msg['id'] for msg in body['messages']]
headers['Content-Type'] = 'multipart/mixed; boundary=%s' % self.BOUNDARY
post_body = []
for msg_id in msg_ids:
post_body.append(
"--%s\n"
"Content-Type: application/http\n\n"
"GET /gmail/v1/users/me/messages/%s?format=raw\n"
% (self.BOUNDARY, msg_id))
post_body.append("--%s--\n" % self.BOUNDARY)
post = '\n'.join(post_body)
(headers, body) = _conn.request(
SERVER_URL + '/batch',
method='POST', body=post, headers=headers)
Great reply!
If somebody wants to use a raw function in php to make batch requests for fetching emails corresponding to message ids, please feel free to use mine.
function perform_batch_operation($auth_token, $gmail_api_key, $email_id, $message_ids, $BOUNDARY = "gmail_data_boundary"){
$post_body = "";
foreach ($message_ids as $message_id) {
$post_body .= "--$BOUNDARY\n";
$post_body .= "Content-Type: application/http\n\n";
$post_body .= 'GET https://www.googleapis.com/gmail/v1/users/'.$email_id.
'/messages/'.$message_id.'?metadataHeaders=From&metadataHeaders=Date&format=metadata&key='.urlencode($gmail_api_key)."\n\n";
}
$post_body .= "--$BOUNDARY--\n";
$headers = [ 'Content-type: multipart/mixed; boundary='.$BOUNDARY, 'Authorization: OAuth '.$auth_token ];
$curl = curl_init();
curl_setopt($curl,CURLOPT_URL, 'https://www.googleapis.com/batch' );
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl,CURLOPT_CONNECTTIMEOUT , 60 ) ;
curl_setopt($curl, CURLOPT_TIMEOUT, 60 ) ;
curl_setopt($curl,CURLOPT_POSTFIELDS , $post_body);
curl_setopt($curl, CURLOPT_RETURNTRANSFER,TRUE);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER,0);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
$tmp_response = curl_exec($curl);
curl_close($curl);
return $tmp_response;
}
FYI the above function gets just the headers for the emails, in particular the From and Date fields, please adjust according to the api documentation https://developers.google.com/gmail/api/v1/reference/users/messages/get
In addition to MaK you can perform multiple batch requests using the google-api-php-client and Google_Http_Batch()
$optParams = [];
$optParams['maxResults'] = 5;
$optParams['labelIds'] = 'INBOX'; // Only show messages in Inbox
$optParams['q'] = 'subject:hello'; // search for hello in subject
$messages = $service->users_messages->listUsersMessages($email_id,$optParams);
$list = $messages->getMessages();
$client->setUseBatch(true);
$batch = new Google_Http_Batch($client);
foreach($list as $message_data){
$message_id = $message_data->getId();
$optParams = array('format' => 'full');
$request = $service->users_messages->get($email_id,$message_id,$optParams);
$batch->add($request, $message_id);
}
$results = $batch->execute();
here is the python version, using the official google api client. Note that I did not use the callback here, because I need to handle the responses in a synchronous way.
from apiclient.http import BatchHttpRequest
import json
batch = BatchHttpRequest()
#assume we got messages from Gmail query API
for message in messages:
batch.add(service.users().messages().get(userId='me', id=message['id'],
format='raw'))
batch.execute()
for request_id in batch._order:
resp, content = batch._responses[request_id]
message = json.loads(content)
#handle your message here, like a regular email object
solution from Walty Yeung is worked partially for my use case.
if you guys tried the code and nothing happens use this batch
batch = service.new_batch_http_request()

cakephp PayPal IPN Integration

I am using CakePHP 1.3.10 version and want to integrate PayPal IPN for Payment Process.
I have found some ready made plug-ins though not working properly and returning bunch of errors.
I would like your suggestions, Any body in community using the same with success and any tutorial to integrate in easy steps.
Your response would be appreciated.
Thanks !
I just discovered a nice PHP class, that runs all the PayPal IPN.
https://github.com/Quixotix/PHP-PayPal-IPN/
I turned it into a Component for my CakePhp project.
For this just create a new Component in you app/Controller/Components/ folder and paste the code from that project.
Then Change:
class IpnListener {
...
to
class IpnListener extends Component {
...
Then go back to the controller you want to you PayPal Ipn with and add:
public $components = array('IpnListener');
You can than access the class using:
$this->IpnListener->foo
within your controller functions
Hope this helps
I used Paypal IPN with cake before, and it's simple enough to not have to reply on a plugin. Are you using that to track getting payment in a cake app? You can create the paypal form/button in your paypal account, set the url callback so paypal can notify you. Create a table in DB if you want to record the info paypal sends you. Have a method in the controller to handle the POST data from paypal. Here's my code example:
function blah() {
$this->autoRender = false;
// post back to PayPal system to validate
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
$header = "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen('ssl://www.paypal.com', 443, $errno, $errstr, 30);
if (!$fp) {// HTTP ERROR, we should record the data still..?
} else {
fputs($fp, $header . $req);
while (!feof($fp)) {
$res = fgets($fp, 1024);
if (strcmp($res, "VERIFIED") == 0) {// verified from paypal, processing...
} else if (strcmp($res, "INVALID") == 0) {
// oh no, someone is hijacking us...
}
}
fclose($fp);
}
}
What fields to have in the table depends on what you want to keep. Look up the IPN API, and you can setup sandbox testing with paypal.
