Load from a URI Leave feedback

GroupDocs.Metadata for Java can load a document straight from a web resource. Pass a java.net.URI to the Metadata constructor, and you don’t have to download the file yourself.

The document is downloaded into memory and then loaded the same way as a document loaded from a stream.

The following code sample shows how to load an image from a URL and read its EXIF properties.

advanced_usage.loading_files.LoadFromUri

// The document is downloaded into memory and then loaded like a stream
URI uri = URI.create("https://raw.githubusercontent.com/groupdocs-metadata/GroupDocs.Metadata-for-Java/master/Examples/Resources/SampleFiles/Input/exif.jpg");

try (Metadata metadata = new Metadata(uri)) {
    JpegRootPackage root = metadata.getRootPackageGeneric();
    System.out.println(root.getFileType().getFileFormat());

    if (root.getExifPackage() != null) {
        System.out.println(root.getExifPackage().getMake());
        System.out.println(root.getExifPackage().getModel());
    }
}

Use the Metadata(URI, LoadOptions) constructor to set the file format explicitly or to pass a password.

RAR, 7z, TAR, AAR, GZIP, BZ2, XZ and Zstandard archives are recognized by the file extension, and a URI does not give the library a file name. Set the format of such an archive explicitly, otherwise the archive is not recognized correctly (a RAR archive, for example, is detected as an MP3 file).

URI uri = URI.create("https://raw.githubusercontent.com/groupdocs-metadata/GroupDocs.Metadata-for-Java/master/Examples/Resources/SampleFiles/Input/input.rar");

try (Metadata metadata = new Metadata(uri, new LoadOptions(FileFormat.Rar))) {
    RarRootPackage root = metadata.getRootPackageGeneric();
    System.out.println(root.getRarPackage().getTotalEntries());

    for (RarFile file : root.getRarPackage().getFiles()) {
        System.out.println(file.getName());
    }
}

Note

The whole document is downloaded into memory before it is processed. For large files, consider downloading them to a local disk first and loading them from the path.

You may easily run the code above and see the feature in action in our GitHub examples:
