I am trying to get
"html": "... entire contents of HTML page goes here ..."
in Java using Unirest HTTP communication with MailGun API.
So far I have verified my domain, successfully sent an email via the API, and successfully sent an HTML (basic) email via the API in Java. I am having trouble sending emails (via the API, in Java), whenever I am trying to use any email templates. I was trying to use the suggested email templates present here: https://github.com/mailgun/transactional-email-templates/tree/master/templates .
My code for sending the email is in line with the documentation
public static JsonNode sendSimpleMessage() throws UnirestException {
HttpResponse<com.mashape.unirest.http.JsonNode> request = Unirest.post("https://api.mailgun.net/v3/sub.domain.com" + "/messages")
.basicAuth("api", API_KEY)
.queryString("from", "name <[email protected]>")
.queryString("to", "[email protected]")
.queryString("subject", "Great")
.queryString("html", returnEmail())
.asJson();
return request.getBody();
}
public static String returnEmail() {
try {
return StreamUtils.copyToString(new ClassPathResource("email.html").getInputStream(), Charset.defaultCharset());
} catch (IOException e) {
e.printStackTrace();
}
return "<html><strong>not today</strong></html>";
}
And email.html contains an example from the emails mentioned above (https://github.com/mailgun/transactional-email-templates/tree/master/templates) or any HTML emails, as none work.
The error that I am get is:
com.mashape.unirest.http.exceptions.UnirestException: java.lang.RuntimeException: java.lang.RuntimeException: org.json.JSONException: A JSONArray text must start with '[' at 1 [character 2 line 1].

I also get the same error if I simply paste all the HTML as a string instead of returnEmail(). I also get the same error message if I escape the special characters and/or minify the HTML before sending.
Now I assume that as Unirest is an http library it builds a JSON from the queryString keys and values. While it appears to work with simpel html like "HTML version whatever , it certainly does not like any lengthy/'normal' html, such as an email template.
Can you please suggest any working examples for html emails using the Java API or any hint on how to send the html and have a valid json?
Thanks a ton
.queryString("html", HERE)
, as if the value is<html><strong>whatever</strong></html>
, it is being sent and received as html in any mail client. The question is, still, how do you populate HERE with an html page? Just triedStringEscapeUtils.escapeHtml4(returnEmail()))
and still have the exact same issue – flashjprresponse= Mail.using(configuration) .from(fromName, fromEmail) .to("To Address") .subject("some subject") .html("Content String With Html Tags") .build() .send();
