Build Status

java-sdk

A Java Integration for Transloadit's file uploading and encoding service

Intro

Transloadit is a service that helps you handle file uploads, resize, crop and watermark your images, make GIFs, transcode your videos, extract thumbnails, generate audio waveforms, and so much more. In short, Transloadit is the Swiss Army Knife for your files.

This is a Java SDK to make it easy to talk to the Transloadit REST API.

Install

The JARs can be downloaded manually from our Bintray project, or can be installed from the Maven and Jcenter repositories.

Gradle:

compile 'com.transloadit.sdk:transloadit:0.1.0'

Maven:

<dependency>
  <groupId>com.transloadit.sdk</groupId>
  <artifactId>transloadit</artifactId>
  <version>0.1.0</version>
</dependency>

Usage

All interactions with the SDK begin with the com.transloadit.sdk.Transloadit class.

Create an Assembly

To create an assembly, you use the newAssembly method.

import com.transloadit.sdk.Transloadit;
import com.transloadit.sdk.exceptions.LocalOperationException;
import com.transloadit.sdk.exceptions.RequestException;
import com.transloadit.sdk.response.AssemblyResponse;

import java.io.File;
import java.util.HashMap;

public class Main {
    public static void main(String[] args) {
        Transloadit transloadit = new Transloadit("YOUR_TRANSLOADIT_KEY", "YOUR_TRANSLOADIT_SECRET");

        Assembly assembly = transloadit.newAssembly();

        Map<String, Object> stepOptions = new HashMap<>();
        stepOptions.put("width", 75);
        stepOptions.put("height", 75);
        assembly.addStep("resize", "/image/resize", stepOptions);

        assembly.addFile(new File("PATH/TO/FILE.jpg"));
        try {
            AssemblyResponse response = assembly.save();

            // wait for assembly to finish executing.
            while (!response.isFinished()) {
                response = transloadit.getAssemblyByUrl(response.getSslUrl());
            }

            System.out.println(response.getId());
            System.out.println(response.getUrl());
            System.out.println(response.json());

        } catch (RequestException | LocalOperationException e) {
            // handle exception here
        }
    }
}

Get an Assembly

The method, getAssembly, retrieves the JSON status of an assembly identified by the given assembly_Id.

import com.transloadit.sdk.Transloadit;
import com.transloadit.sdk.exceptions.LocalOperationException;
import com.transloadit.sdk.exceptions.RequestException;
import com.transloadit.sdk.response.AssemblyResponse;

public class Main {
    public static void main(String[] args) {
        Transloadit transloadit = new Transloadit("YOUR_TRANSLOADIT_KEY", "YOUR_TRANSLOADIT_SECRET");

        try {
            AssemblyResponse response = transloadit.getAssembly("ASSEMBLY_ID");

            System.out.println(response.getUrl());
            System.out.println(response.json());

        } catch (RequestException | LocalOperationException e) {
            // handle exception here
        }
    }
}

You may also get an assembly by url with the getAssemblyByUrl method.

    AssemblyResponse response = transloadit.getAssemblyByUrl("ASSEMBLY_URL");

Cancel an Assembly

To cancel an executing assembly, you use the cancelAssembly method, passing the assembly id as a parameter.

import com.transloadit.sdk.Transloadit;
import com.transloadit.sdk.exceptions.LocalOperationException;
import com.transloadit.sdk.exceptions.RequestException;
import com.transloadit.sdk.response.AssemblyResponse;

public class Main {
    public static void main(String[] args) {
        Transloadit transloadit = new Transloadit("YOUR_TRANSLOADIT_KEY", "YOUR_TRANSLOADIT_SECRET");

        try {
            AssemblyResponse response = transloadit.cancelAssembly("ASSEMBLY_ID");

            System.out.println(response.isCancelled()); // prints true
        } catch (RequestException | LocalOperationException e) {
            // handle exception here
        }
    }
}

List Assemblies

The method, listAssemblies, retrieves an array of assemblies according to the given options. Valid options can be page, pagesize, type, fromdate and todate. Please consult the Transloadit API docs for details.

import com.transloadit.sdk.Transloadit;
import com.transloadit.sdk.exceptions.LocalOperationException;
import com.transloadit.sdk.exceptions.RequestException;
import com.transloadit.sdk.response.ListResponse;

import java.util.HashMap;

public class Main {
    public static void main(String[] args) {
        Transloadit transloadit = new Transloadit("YOUR_TRANSLOADIT_KEY", "YOUR_TRANSLOADIT_SECRET");

        try {
            Map<String, Object> options = new HashMap<>();
            options.put("pagesize", 10);
            ListResponse response = transloadit.listAssemblies(options);

            System.out.println(response.size());  // number of assemblies on the list.
            System.out.println(response.getItems());  // returns an iterable json array

        } catch (RequestException | LocalOperationException e) {
            // handle exception here
        }
    }
}

Create a Template

To create a new template, you use the newTemplate method, passing the template name as a parameter.

public class Main {
    public static void main(String[] args) {
        Transloadit transloadit = new Transloadit("YOUR_TRANSLOADIT_KEY", "YOUR_TRANSLOADIT_SECRET");

        Template template = transloadit.newTemplate("MY_TEMPLATE_NAME");

        Map<String, Object> resizeOptions = new HashMap<>();
        resizeOptions.put("width", 75);
        resizeOptions.put("height", 75);

        Map<String, Object> optimizeOptions = new HashMap<>();
        optimizeOptions.put("use", ":original");

        template.addStep("resize", "/image/resize", resizeOptions);
        template.addStep("resize", "/image/optimize", optimizeOptions);

        try {
            Response response = template.save();

            System.out.println(response.json());
            System.out.println(response.json().getString("id")); // gets the template id.
        } catch (RequestException | LocalOperationException e) {
            // handle exception here
        }
    }
}

Update a Template

        Steps steps = new Steps();

        Map<String, Object> stepOptions = new HashMap<>();
        stepOptions.put("width", 150);
        stepOptions.put("height", 150);
        steps.addStep("resize", "/image/resize", stepOptions);

        Map<String, Object> templateOptions = new HashMap<>();
        templateOptions.put("steps", steps.toMap());
        templateOptions.put("name", "MY_NEW_TEMPLATE_NAME");

        try {
            Response response = transloadit.updateTemplate("TEMPLATE_ID", templateOptions);

        } catch (RequestException | LocalOperationException e) {
            // handle exception here
        }
    }
