Akismet for Kotlin/Java

Akismet for Kotlin/Java/Android is a pretty complete and straightforward implementation of the Automattic's Akismet API, a free service which can be used to actively stop comments spam.

Examples (TL;DR)

Kotlin

val akismet = Akismet(apiKey = "YOUR_API_KEY", blog = "YOUR_BLOG_URL")
val comment = AkismetComment(userIp = "127.0.0.1", userAgent = "curl/7.29.0")

with(comment) {
    referrer = "http://www.google.com"
    type = AkismetComment.TYPE_COMMENT
    author = "admin"
    authorEmail = "[email protected]"
    authorUrl = "http://www.CheckOutMyCoolSite.com"
    dateGmt = Akismet.dateToGmt(Date())
    content = "It means a lot that you would take the time to review our software."
}
// ...

val isSpam = akismet.checkComment(comment)
if (isSpam) {
    // ...
}

Java

final Akismet akismet = new Akismet("YOUR_API_KEY", "YOUR_BLOG_URL");
final AkismetComment comment = new AkismetComment("127.0.0.1", "curl/7.29.0");

comment.setReferrer("http://www.google.com");
comment.setType(AkismetComment.TYPE_COMMENT);
comment.setAuthor("admin");
comment.setAuthorEmail("[email protected]");
comment.setAuthorUrl("http://www.CheckOutMyCoolSite.com");
comment.setDateGmt(Akismet.dateToGmt(new Date()));
comment.setContent("It means a lot that you would take the time to review our software.");
//...

final boolean isSpam = akismet.checkComment(comment);
if (isSpam) {
    // ...
}

Gradle

To use with Gradle, include the following dependency in your build file:

repositories {
    jcenter()
}

dependencies {
    implementation("net.thauvin.erik:akismet-kotlin:0.9.2")
}

HttpServletRequest

The more information is sent to Akismet, the more accurate the response is. An HttpServletRequest can be used as a parameter so that all the relevant information is automatically included.

AkismetComment(request = context.getRequest())

This will ensure that the user's IP, agent, referrer and various environment variables are automatically extracted from the request.

JSON

Since comments mis-identified as spam or ham can be submitted to Askimet to improve the service. A comment can be saved as a JSON object to be stored in a database, etc.

var json = comment.toJson()

At a latter time, the comment can then be submitted:

akismet.submitSpam(Akismet.jsonComment(json))
