How to get websocket in webclient of gargoylesoftware

Question

Is Websocket supported in gargoylesoftware library? I want to get websocket object in webclient.

Answer 1

Yes, WebSocket is supported since version 2.11. However, it is always recommended to use the latest version.

Please ensure you use BrowserVersion with recent browser, e.g. CHROME, FIREFOX_38, or INTERNET_EXPLORER_11.

E.g.:

try (final WebClient webClient = new WebClient(BrowserVersion.CHROME)) {

HtmlUnit will automatically handle the JavaScript with WebSocket.

Update:

To intercept the requests and responses, you can use:

    new WebConnectionWrapper(webClient) {

        public WebResponse getResponse(WebRequest request) throws IOException {
            WebResponse response = super.getResponse(request);
            if (request.getUrl().toExternalForm().contains("my_url")) {
                String content = response.getContentAsString("UTF-8");

                //change content

                WebResponseData data = new WebResponseData(content.getBytes("UTF-8"),
                        response.getStatusCode(), response.getStatusMessage(), response.getResponseHeaders());
                response = new WebResponse(data, request, response.getLoadTime());
            }
            return response;
        }
    };
