点击一个HtmlUnit不工作的按钮

Clicking a button with HtmlUnit not working

我试图使用HtmlUnit 2.23单击登录按钮，使用DomElement或executeJavaScript，但都不起作用。还有别的办法让它工作吗?这是代码:

@Test
public void noLogin() throws Exception {
    final WebClient webClient = new WebClient(BrowserVersion.BEST_SUPPORTED);
    //see http://stackoverflow.com/questions/3600557/turning-htmlunit-warnings-off/18563576#18563576
    java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(Level.OFF); 
    //see http://stackoverflow.com/questions/18556200/htmlunit-button-click
    webClient.getOptions().setJavaScriptEnabled(true);      
    webClient.getOptions().setThrowExceptionOnScriptError(false);
    webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
    webClient.setAjaxController(new NicelyResynchronizingAjaxController());
    final HtmlPage loginPage = webClient.getPage("https://sandbox.paydirekt.de/account/#/login");
    loginPage.getElementById("username").setAttribute("value", "no");
    loginPage.getElementById("password").setAttribute("value", "login");
    //final HtmlPage welcomePage = ((DomElement)loginPage.getFirstByXPath("//button[@type='submit']")).click();
    //see http://stackoverflow.com/questions/14474580/use-htmlunit-doesnt-work-button-click
    //ScriptResult result = loginPage.executeJavaScript("javascript:document.getElementsByName('loginForm')[0].submit();");
    ScriptResult result = loginPage.executeJavaScript("javascript:document.getElementsByClassName('loginBox__loginButton button button--full')[0].click()");
    Page page = result.getNewPage();
    if (page.isHtmlPage()) {
        HtmlPage welcomePage = ((HtmlPage)page);
        System.out.println(welcomePage.asText());
        Assert.assertTrue(welcomePage.asText().contains("Benutzername oder Passwort nicht korrekt."));
    }
    webClient.close();
}

您还可以使用HTMLUnit提供的连接包装器手动检查每个请求和响应。下面是一个例子

            new WebConnectionWrapper(webClient) {
                public WebResponse getResponse(WebRequest request) throws IOException {
                    WebResponse response = super.getResponse(request);
                    if (request.getUrl().toExternalForm().contains("THE URL YOU WANT TO CHECK")) {
                        String content = response.getContentAsString("UTF-8");
//CHECK CONTENT HERE

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