# [Bitly](https://dev.bitly.com/v4/) Shortener for Kotlin, Java & Android

A simple implementation of the [Bitly](https://bit.ly/) link shortening (Bitlinks) [API v4](https://dev.bitly.com/api-reference).

## Examples (TL;DR)

```kotlin
val bitly = Bitly(/* "YOUR_API_ACCESS_TOKEN from https://bitly.is/accesstoken" */)

// Shorten
bitly.bitlinks().shorten("https://erik.thauvin.net/blog")

// Expand
bitly.bitlinks().expand("https://bit.ly/380ojFd")

// Clicks Summary
bitly.bitlinks().clicks("https://bit.ly/380ojFd")

// Create a bitlink
bitly.bitlinks().create(title = "Erik's Weblog", long_url = "https://erik.thauvin.net/blog/")

// Update a bitlink
bitly.bitlinks().update("https://bit.ly/380ojFd", title="Erik's Weblog", tags = arrayOf("blog", "weblog"))
```

 - View [Kotlin](https://github.com/ethauvin/bitly-shorten/blob/master/examples/src/main/kotlin/com/example/BitlyExample.kt) or [Java](https://github.com/ethauvin/bitly-shorten/blob/master/examples/src/main/java/com/example/BitlySample.java) Examples.

### API Access Token

The Bitly API [Access Token](https://bitly.is/accesstoken) can be specified directly as well as via the `BITLY_ACCESS_TOKEN` environment variable or properties key.

```kotlin
// Env Variable or System Property
val bitly = Bitly()

// Properties file path
val bitly = Bitly(File("my.properties"))

```
```ini
# my.properties
BITLY_ACCESS_TOKEN=abc123def456ghi789jkl0
```

### Gradle, Maven, etc.

To use with [Gradle](https://gradle.org/), include the following dependency in your [build](https://github.com/ethauvin/bitly-shorten/blob/master/examples/build.gradle.kts) file:

```gradle
repositories {
    mavenCentral()
    maven { url = uri("https://oss.sonatype.org/content/repositories/snapshots") } // only needed for SNAPSHOT
}

dependencies {
    implementation("net.thauvin.erik:bitly-shorten:0.9.3")
}
```

Instructions for using with Maven, Ivy, etc. can be found on [Maven Central](https://search.maven.org/artifact/net.thauvin.erik/bitly-shorten/0.9.3/jar).

## Java

To make it easier to use the library with Java, configuration builders are available:

```java
var config = new CreateConfig.Builder()
        .title("Erik's Weblog")
        .tags(new String[] { "blog", "weblog"})
        .long_url("https://erik.thauvin.net/blog")
        .build();

bitly.bitlinks().create(config);
```
```java
var config = new UpdateConfig.Builder()
        .bitlink("https://bit.ly/380ojFd")
        .title("Erik's Weblog")
        .tags(new String[] { "blog", "weblog"})
        .build();

bitly.bitlinks().update(config);
```

### JSON

All implemented API calls can return the full JSON responses:

```kotlin
bitly.bitlinks().shorten("https://www.erik.thauvin.net/blog", toJson = true)
```
```json
{
    "created_at": "2020-02-26T06:50:08+0000",
    "link": "https://bit.ly/380ojFd",
    "id": "bit.ly/380ojFd",
    "long_url": "https://erik.thauvin.net/blog"
}
```

You can also access the last response from implemented API calls using:

```kotlin
val bitlinks = Bitlinks(apikey)
val shortUrl = bitlinks.shorten(longUrl)
val response = bitlinks.lastCallResponse

if (response.isSuccessful) {
    println(response.body)
} else {
    println("${response.message}: ${response.description} (${response.statusCode})")
}
```

Non-implemented API endpoints can also be called directly:

```kotlin
val response = bitly.call("/user", method = Methods.GET)
if (response.isSuccessful) {
    println(response.body)
}
```
```json
{
    "created": "2009-06-12T19:00:45+0000",
    "modified": "2016-11-11T19:50:33+0000",
    "login": "johndoe",
    "is_active": true,
    "is_2fa_enabled": true,
    "name": "John Doe",
    "emails": [
        {
            "email": "john@doe.com",
            "is_primary": true,
            "is_verified": true
        }
    ],
    "is_sso_user": false,
    "default_group_guid": "ABCde1f23gh"
}
```
