Java Alchemy API is an interface to the Alchemy API
To access Alchemy's API you will need to Register for an API Key.
The Java SDK that Alchemy provides seemed very basic and incomplete to me so I created my own.
-
They provide classes called "test" but they are examples. They are not actual unit tests.
-
The return object is always a dom Document.
-
The source code format does not follow the Java standard. For instance, method names begin with or contain nothing but capital letters (e.g, GetInstanceFromFile, GET, POST). Others are proper (e.g., getNodeValue)
-
It gives the client the ability to specify the return format from the call to the service (either RDF or XML). If you return objects there is no need for the client to specify or even care what the output format is.
Be sure to see the Changelog
A recent change (maven 1.1.0) has removed from the Client the loading of the API key from an external resource.
-
new Client()does nothing -
new Client(String)expects the argument to be the API key
Removed:
new Client(String)where the String is the classpath to a resource containing the API key
This project uses Apache Maven to build. To build and install into your local Maven repository:
mvn clean install
<dependency>
<groupId>com.likethecolor</groupId>
<artifactId>alchemy</artifactId>
<version>1.3.1</version>
</dependency>
You can look at the pom.xml to find the dependencies. In short:
Note that for testing the slf4j-log4j12 artifact is a dependency (scope: test). Logging is available when running unit tests if needed.
final String apiKey = "0a1b2c3d4e5f6g7h8i9j0a1b2c3d4e5f6g7h8i9j";
final Client client = new Client(apiKey);
OR
final Client client = new Client();
client.setAPIKey(apiKey);
final AbstractCall<AuthorAlchemyEntity> authorCall = new AuthorCall(new CallTypeUrl("http://www.politico.com/blogs/media/2012/02/detroit-news-ed-upset-over-romney-edit-115247.html"));
final Response response = client.call(authorCall);
System.out.println(response);
System.out.println();
which is slightly more verbose version of this:
final AbstractCall<AuthorAlchemyEntity> authorCall = new AuthorCall(new CallTypeUrl("http://www.politico.com/blogs/media/2012/02/detroit-news-ed-upset-over-romney-edit-115247.html"));
System.out.println(client.call(authorCall));
System.out.println();
