Installation

Get the latest release from Maven Central.

Usage

import com.twingly.search.*;
public class Test{
    public static void main(String[] args){
        String apiKey = "API_KEY";
        // create Client object using your API key
        Client client = new UrlConnectionClient(apiKey);
        String q = "spotify";
        Result result = client.makeRequest(q);
        // Get the total number of matches returned
        int numberOfMatchesReturned = result.getNumberOfMatchesReturned();
        // Get the total number of matches to the search query
        int numberOfMatchesTotal = result.getNumberOfMatchesTotal();
        // Get number of seconds it took to execute query
        double secondsElapsed = result.getSecondsElapsed();
        for (Post p : result.getPosts()){
            System.out.println(p.getUrl());             // print url for each post
            System.out.println(p.getTitle());           // print title for each post
        }
    }
}

To learn more about the features of this client, check out the example code that can be found in example.

To learn more about the capabilities of the API, please read the Twingly Search API documentation.

API key from Java system properties

Additionally, you can create Client object with API key from Java system properties (property name is TWINGLY_SEARCH_KEY):

import com.twingly.search.client.*;
public class Test{
    public static void main(String[] args){
        Client client = new UrlConnectionClient(); // create client object with API key from java system property
    }
}

To do so, you will need to run Java with property. For example, run your own jar file with twingly search key property:

java -jar myJar.jar -DTWINGLY_SEARCH_KEY=some_key_value

Exception handling

Given exception hierarchy is now available:

Check Twingly Search API documentation for additional information about error codes.

Requirements

Development

Tests

Make sure you have all the dependencies

gradlew assemble

Run the tests

gradlew check

Generate coverage report, using JaCoCo. Note that you need to run the tests first.

gradlew jacocoTestReport

open build/jacocoHtml/index.html

Betamax

To be able to run the Betamax-based tests you need to add Betamax's certificate into Java's trust store, cacerts:

sudo keytool -importcert -keystore $JAVA_HOME/jre/lib/security/cacerts -file betamax.pem -alias betamax -storepass changeit -noprompt

It is adviced to remove the certificate after testing is done:

sudo keytool -delete -keystore $JAVA_HOME/jre/lib/security/cacerts -alias betamax -storepass changeit -noprompt

Note that the temporary files generated by Betamax:

need to be removed if generated before Betamax's certificate was added to the trust store, tests will fail otherwise.

For more information, check out Betamax's SSL configuration documentation.

JavaDoc generation

To generate java docs just run gradle task javadoc:

gradlew javadoc

This will save javadocs in docs folder under build-folder.

One-jar generation

To generate one fat jar library with all compile dependencies just run gradle task generateOneJar:

gradlew generateOneJar

This will save JAR file with all needed dependencies in build/libs/ with -all suffix. (like twingly-search-api-java-all-0.0.1.jar)
