Re: [google-appengine] Re: GAE Web app sending mail using SendGrid

[Adam Jack]

I don't know the background here, but in case any of this helps:

Do you have an API key from SendGrid?

   https://app.sendgrid.com/settings/api_keys

In your appengine-web.xml  set the environment variable to pass that API
key into:


  




https://cloud.google.com/appengine/docs/standard/java/config/appref


Sorry if I am off base, it just looks similar to what I am doing (with Go.)


regards,

Adam

[Alexis CAPGEMINI]

Can you please explain how you did this ?

I'm still stuck with an error here :  SendGrid sendgrid = new SendGrid( 
System.getenv("SENDGRID_SENDER"));  

Thanks

I have solved the problem. I had to use Urlfetch configuration in 
appengine-web.xml and use URLFetch class instead of HttpURLConnection. It 
works now. Thanks for the help!

If you would like us to look more in-depth in the issue, you should write a 
private message with your project ID. You can do this using the drop-down

There are a lot of advantages offered by SendGrid to free account holders. 
You may check details on the SendGrid pricing page 
. Payment detail are not requested on that 
page. 

How did you get your application ready? You are encouraged to read the 
"Preparing the application" sub-chapter 

 
of the SendGrid tutorial. Have you followed each and every step listed on 
that page? 

You seem to need help for a coding issue; it may be worth mentioning: this 
is a tracker for Cloud SDK specific issues. When it comes strictly to 
programming and coding, you’ll be at an advantage to rather post your 
questions on Stackoverflow, to gain this way access to a large number of 
experts; Stackoverflow and other similar forums are meant to provide help 
with coding.

[google-appengine] Re: GAE Web app sending mail using SendGrid

[Rashmi S]

Just want to confirm, is updation of billing account necessary even for free 
trial versions of sendgrid or mailjef. Will it not work without payment 
details? And could it be possible that these services, even recaptcha is 
failing with an IOexception or server error?...with reference to this doc: 
https://cloud.google.com/appengine/docs/standard/java/issue-requests#java_8_runtime_vs_java_7_behavior
 . Can anyone clarify..

At this stage, we'll need your project ID for closer and more in-depth 
inspection. As this is private information, you should send it by private 
message, using the drop-down menu of the "reply" button at the top right of 
a posting window. 

It may be worthile mentioning here that this discussion group is oriented 
more towards general opinions, trends and issues of general nature touching 
the app engine. For coding and programming architecture, you are better 
served in a forum such as stackoverflow, where experienced programmers are 
within reach and ready to help.

[google-appengine] Re: GAE Web app sending mail using SendGrid

[Rashmi S]

Hi George, thanks for the reply!

My project is a spring MVC project. I'm using a trial version of Sendgrid. I 
haven't updated my billing details(could this be a reason for failure).
Here's the relevant code snippet :

Method 1:
public static boolean sendEmail(String emailId) {

Sendgrid mail = new Sendgrid("my_username","my_password"); //Input: 
SendGrid username, password
mail.setTo(emailId) //to ID
.setFrom("my_email...@gmail.com") //from ID
.setSubject("Sending first mail with Sendgrid") //subject
.setText("thanks for subscribing!"); //content

try {
mail.send();
}
catch (JSONException e) {
logger.info("JSON exception occured");
return false;
 }
return true;
}

Method 2: I've tried the version that uses Api key too:
 
Email from = new Email("my_emai...@gmail.com");
String subject = "Sending first mail with Sendgrid";
Email to = new Email(emailId);
Content content = new Content("text/plain", "thanks for subscribing!");
Mail mail = new Mail(from, subject, to, content);

SendGrid sg = new SendGrid(SENDGRID_API_KEY);
Request request = new Request();
request.setMethod(Method.POST);
request.setEndpoint("mail/send");
request.setBody(mail.build());
Response response = sg.api(request);

if(response.getStatusCode()!=200) {
logger.info("response status is ", response.getStatusCode());
return false;
}

Hello Rashmi, 

Have you followed all steps in the referred document? Authentication works 
well? How does your email-related code looks like? A sample of your code 
would greatly help in setting the basis of further investigations. You may 
consider having a look at the SendGrid Tutorial 
, to make sure 
you have covered all needed steps, to secure full functionality in the 
deployed app.
