How to Download Files from URL

The ability to download file from URL is important for various applications such as web scraping and content analysis. Aspose.HTML for Java is a robust library that simplifies this process by offering developers a set of tools to navigate and gather information from HTML documents seamlessly. Let’s explore how to save file from URL with Java.

Save File from URL Using Java

Using Aspose.HTML for Java library, you can easily create your own application, since our API provides a powerful toolset to analyze and collect information from HTML documents. If you want to use HTML data scraping features in your product or programmatically download file from URL, see the code example below:

// Create a blank document; it is required to access the network operations functionality
final HTMLDocument document = new HTMLDocument();

// Create a URL with the path to the resource you want to download
Url url = new Url("https://docs.aspose.com/html/net/message-handlers/message-handlers.png");

// Create a file request message
final RequestMessage request = new RequestMessage(url);

// Download file from URL
final ResponseMessage response = document.getContext().getNetwork().send(request);

// Check whether response is successful
if (response.isSuccess()) {
    String[] split = url.getPathname().split("/");
    String path = split[split.length - 1];

    // Save file to a local file system
    FileHelper.writeAllBytes(path, response.getContent().readAsByteArray());
}

Steps to Save File from URL

1. Use the HTMLDocument() constructor to create an empty instance of the HTMLDocument class. This step is required to enable network access within the context of the document.
2. Create a Url object and pass the path of the file you want to download.
3. Use the RequestMessage(url) constructor to create a request message targeting the specified URL. The url parameter defines the destination for the network request.
4. Send the request and receive the response from the specified URL. If the request is successful, extract the file name from the URL path.
5. Use FileHelper.writeAllBytes() to save the file to your local file system.

Downloading files from URLs can be helpful for offline access when your internet connection is limited, for collaboration and sharing content, for archiving and backing up to prevent data loss, or simply for storing essential resources, such as documents, images, videos, or audio files, for future use. It is also a useful method for remote access to educational materials, allowing you to study anytime and anywhere – even while commuting or traveling.
