另一种选择是允许我填写带有复选框和单选按钮的HTML表单。
我正在创建一个需要用户输入的Android应用程序,并将该数据使用html表单发送到网站,然后将其填写,提交表单并返回以下结果页面。
我已经设法在eclipse中使用HtmlUnit库将数据发送到html表单并检索页面(我在下面发布了Java代码)。
但是,当我将该代码复制到我的Android项目中时,我发现Android不支持HtmlUnit库。
HtmlUnit是否有Android的另一种选择?替代方法应该能够将文本,复选框,单选按钮填写到HTML表单中,然后单击提交按钮
HTML表单代码:
<form method="post" action="https://www.xxxxx.com/cgi-bin/xxxxxx.cgi"> <p><em>Person:</em> <input size="18" name="name"><br> <input type="radio" name="login" value="no" checked="">Name <input type="radio" name="login" value="yes">Username</p> <p><em>Title:</em> <input size="18" name="title"></p> <p><em>Department:</em> <input size="18" name="department"></p> <p><em>Groups to Search:</em><br> <input type="checkbox" name="get_student" value="yes" checked=""> Students<br> <input type="checkbox" name="get_alum" value="yes" checked=""> Alumni<br> <input type="checkbox" name="get_staff" value="yes" checked=""> Staff<br> <input type="checkbox" name="get_faculty" value="yes" checked=""> Faculty</p> <p><input type="submit" value="Search"></p> </form>
HtmlUnit Java代码:
public static String submittingForm() throws Exception { final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_38); webClient.getOptions().setJavaScriptEnabled(false); webClient.getOptions().setThrowExceptionOnScriptError(false); webClient.setAjaxController(new NicelyResynchronizingAjaxController()); WebRequest request = new WebRequest(new URL("https://www.xxxxx.com/")); // Get the first page HtmlPage page1 = webClient.getPage(request); System.out.println("PULLING LINKS/ LOADING:"); // Get the form that we are dealing with and within that form, // find the submit button and the field that we want to change. List<HtmlForm> listform = page1.getForms(); HtmlForm form = listform.get(0); HtmlElement Name = page1.getElementByName("name"); Name.click(); Name.type("Adonay"); HtmlElement nameRadio = page1.getFirstByXPath("/html/body//div[@id='wrapper']//div[@id='layout']//div[@id='container']//div[@id='col1']//div[@id='content']//div[@class='directory-search']//form//input[@type='radio' and @value='no']"); HtmlElement userRadio = page1.getFirstByXPath("/html/body//div[@id='wrapper']//div[@id='layout']//div[@id='container']//div[@id='col1']//div[@id='content']//div[@class='directory-search']//form//input[@type='radio' and @value='yes']"); /* userRadio.click(); click when username wanted*/ HtmlElement Title = page1.getElementByName("title"); Title.click(); Title.type(""); HtmlElement Department = page1.getElementByName("department"); Department.click(); Department.type(""); HtmlElement studentBox = page1.getFirstByXPath("/html/body//div[@id='wrapper']//div[@id='layout']//div[@id='container']//div[@id='col1']//div[@id='content']//div[@class='directory-search']//form//input[@type='checkbox' and @name='get_student']"); studentBox.click(); //add clicker here HtmlElement alumniBox = page1.getFirstByXPath("/html/body//div[@id='wrapper']//div[@id='layout']//div[@id='container']//div[@id='col1']//div[@id='content']//div[@class='directory-search']//form//input[@type='checkbox' and @name='get_alum']"); alumniBox.click(); //add clicker here HtmlElement staffBox = page1.getFirstByXPath("/html/body//div[@id='wrapper']//div[@id='layout']//div[@id='container']//div[@id='col1']//div[@id='content']//div[@class='directory-search']//form//input[@type='checkbox' and @name='get_staff']"); staffBox.click(); //add clicker here HtmlElement facultyBox = page1.getFirstByXPath("/html/body//div[@id='wrapper']//div[@id='layout']//div[@id='container']//div[@id='col1']//div[@id='content']//div[@class='directory-search']//form//input[@type='checkbox' and @name='get_faculty']"); facultyBox.click(); //add clicker here HtmlElement button = page1.getFirstByXPath("/html/body//div[@id='wrapper']//div[@id='layout']//div[@id='container']//div[@id='col1']//div[@id='content']//div[@class='directory-search']//form//input[@type='submit' and @value='Search']"); // Change the value of the text field // Now submit the form by clicking the button and get back the second page. HtmlPage page2 = button.click(); webClient.waitForBackgroundJavaScript(200); return(page2.asXml()); }
伙计们,我找到了另一种方法。由于我知道服务器地址,因此我尝试使用将数据直接发布到该地址DataOutputStream。看下面的代码:
DataOutputStream
public String searchDirectory() throws IOException { URL url = new URL("https://www.xxxxx.com/xxxxx/xxxxx.cgi"); URLConnection con = url.openConnection(); con.setDoInput(true); con.setDoOutput(true); con.setUseCaches(false); con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); DataOutputStream printout = new DataOutputStream (con.getOutputStream ()); String parameters =("name=" + URLEncoder.encode("DATA HERE", "UTF-8")); printout.writeBytes (parameters); printout.flush (); printout.close (); /*InputStream inputStream = getApplicationContext().getResources().getAssets().open("White Pages Query Results.html"); InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "UTF-8"); */ DataInputStream input = new DataInputStream (con.getInputStream ()); String line; String htmlCode = ""; while((line = input.readLine()) != null) { htmlCode += line; } return htmlCode; }
如您所见,我使用Html Elements的名称通过java访问它们。但是,正如您从原始文章中的html表单代码中看到的那样,单选按钮具有相同的名称,如何在不使用其名称的情况下分别访问/填充它们?
