背景:我有一个网页(.aspx),其中有几个下拉列表。列表值是根据先前下拉列表的选择使用 Ajax 调用填充的。选择所有下拉列表的值后,我们可以单击下载按钮,数据将根据下载的数据进行下载,我们需要执行一些其他操作。
我已经做了什么:我可以通过正确调用 ajax 来设置下拉数据,但是发送一个 post 请求是个问题。这是代码片段/伪代码。
随意使用任何工具和 java
public static void main(String[] args) throws FailingHttpStatusCodeException, IOException {
final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_17);
WebRequest request = new WebRequest(new URL(DataDownloader.MY_URL),HttpMethod.POST);
webClient.getOptions().setThrowExceptionOnScriptError(false);
webClient.setJavaScriptTimeout(10000);
webClient.getOptions().setJavaScriptEnabled(true);
webClient.setAjaxController(new NicelyResynchronizingAjaxController());
webClient.getOptions().setTimeout(10000);
HtmlPage page = webClient.getPage(request);
HtmlSelect firstDd = (HtmlSelect) page.getElementById("dd1_id");
List<HtmlOption> firstOption = firstDd.getOptions();
firstDd.setSelectedAttribute(firstOption.get(2), true);
webClient.waitForBackgroundJavaScript(3000);
HtmlPage pgAfterFirstDd = (HtmlPage) webClient.getCurrentWindow().getEnclosedPage();
HtmlSelect secondDd = (HtmlSelect) pgAfterFirstDd.getElementById("dd2_id");
List<HtmlOption> secondOption = secondDd.getOptions();
secondDd.setSelectedAttribute(secondOption.get(2), true);
webClient.waitForBackgroundJavaScript(10000);
//set the value for all other dropdowns
HtmlPage finalpage = (HtmlPage) webClient.getCurrentWindow().getEnclosedPage();
HtmlForm form = finalpage.getHtmlElementById("aspnetForm");
webClient.waitForBackgroundJavaScript(10000);
request.setRequestBody("REQUESTBODY");
Page redirectPage = webClient.getPage(request);
// HtmlSubmitInput submitInput=form.getInputByName("btnSubmit");
// submitInput.click();
/*HtmlButton submitButton = (HtmlButton) pageAfterWard.createElement("btnSubmit");
submitButton.setAttribute("type", "submit");
form.appendChild(submitButton);
HtmlPage nextPage = (HtmlPage) submitButton.click();*/
