java - 在Java中模拟点击提交按钮

Question

我正在用Java编写程序，我想填写表单的指定字段，模拟提交点击，从而得到结果页面。我正在 URL http://stu21.kntu.ac.ir/Login.aspx 上测试我的想法，该 URL 有两个字段 txtusername 和 txtpassword >。我正在尝试以下代码，但它不会为我返回结果页面。我该怎么做 ？这段代码我做错了什么？

        DefaultHttpClient conn = new DefaultHttpClient();
        conn = new DefaultHttpClient();

        ArrayList<NameValuePair> pairs = new ArrayList<NameValuePair>();
        pairs.add(new BasicNameValuePair("txtusername", "8810103"));
        pairs.add(new BasicNameValuePair("txtpassword", "8810103"));

        HttpPost httpPost = new HttpPost("http://stu21.kntu.ac.ir/Login.aspx");
        UrlEncodedFormEntity entity = new UrlEncodedFormEntity(pairs,
                "UTF-8");

        httpPost.setHeader(
                "UserAgent",
                "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.19 (KHTML, like Gecko) Ubuntu/12.04 Chromium/18.0.1025.151 Chrome/18.0.1025.151 Safari/535.19");

        httpPost.setEntity(entity);
        HttpResponse response = conn.execute(httpPost);
        InputStream is = response.getEntity().getContent();
        RandomAccessFile raf = new RandomAccessFile(
                "/home/hossein/Desktop/random.aspx", "rw");
        raf.seek(0);

        int bytes = 0;
        byte[] buffer = new byte[1024];

        while ((bytes = is.read(buffer)) != -1)
            raf.write(buffer, 0, bytes);

        raf.close();
        is.close();

抱歉，如果我的问题与其他线程重复，我无法在其他线程上找到我的解决方案。

提前致谢:)

我认为你需要HTTPUnit 。 javaworld 有一个很好的教程。

看看下面的例子:

public void testGoodLogin() throws Exception {
    WebConversation     conversation = new WebConversation();
    WebRequest  request = new GetMethodWebRequest( "http://www.meterware.com/servlet/TopSecret" );
    WebResponse response = conversation.getResponse( request );

    WebForm loginForm = response.getForms()[0];
    request = loginForm.getRequest();
    request.setParameter( "name", "master" );

    // "clicking the button" programatically
    response = conversation.getResponse( request );

    assertTrue( "Login not accepted", 
               response.getText().indexOf( "You made it!" ) != -1 );
    assertEquals( "Page title", "Top Secret", response.getTitle() );
} 

我相信您可以像这样进行测试。
