Quickstart: Use the Bing Image Search Java client library

  • Artikel

Use this quickstart to make your first image search using the Bing Image Search client library, which is a wrapper for the API and contains the same features. This simple Java application sends an image search query, parses the JSON response, and displays the URL of the first image returned.

The source code for this sample is available on GitHub with additional error handling and annotations.

Prerequisites

The latest version of the Java Development Kit (JDK)

Install the Bing Image Search client library dependencies by using Maven, Gradle, or another dependency management system. The Maven POM file requires the following declaration:

 <dependencies>
    <dependency>
      <groupId>com.microsoft.azure.cognitiveservices</groupId>
      <artifactId>azure-cognitiveservices-imagesearch</artifactId>
      <version>1.0.1</version>
    </dependency>
 </dependencies>

Create and initialize the application

  1. Create a new Java project in your favorite IDE or editor, and add the following imports to your class implementation:

    import com.microsoft.azure.cognitiveservices.search.imagesearch.BingImageSearchAPI;
import com.microsoft.azure.cognitiveservices.search.imagesearch.BingImageSearchManager;
import com.microsoft.azure.cognitiveservices.search.imagesearch.models.ImageObject;
import com.microsoft.azure.cognitiveservices.search.imagesearch.models.ImagesModel;

  2. In your main method create variables for your subscription key, and search term. Then instantiate the Bing Image Search client.

    final String subscriptionKey = "COPY_YOUR_KEY_HERE";
String searchTerm = "canadian rockies";
//Image search client
BingImageSearchAPI client = BingImageSearchManager.authenticate(subscriptionKey);

Send a search request to the API

  1. Using bingImages().search(), send the HTTP request containing the search query. Save the response as a ImagesModel.

     ImagesModel imageResults = client.bingImages().search()
             .withQuery(searchTerm)
             .withMarket("en-us")
             .execute();

Parse and view the result

Parse the image results returned in the response. If the response contains search results, store the first result and print out its details, such as a thumbnail URL, the original URL, along with the total number of returned images.

if (imageResults != null && imageResults.value().size() > 0) {
    // Image results
    ImageObject firstImageResult = imageResults.value().get(0);

    System.out.println(String.format("Total number of images found: %d", imageResults.value().size()));
    System.out.println(String.format("First image thumbnail url: %s", firstImageResult.thumbnailUrl()));
    System.out.println(String.format("First image content url: %s", firstImageResult.contentUrl()));
}
else {
        System.out.println("Couldn't find image results!");
     }
