如何向表单提交帖子请求？

以下是测试表单

假设我需要提交名字 x 和姓氏 y 。所以，我只需输入以下 url

Let's say i need to submit first name x and last name y . So , I can submit the get request simply by entering the following url

http://www.w3schools.com/tags/demo_form_method.asp?fname=x&lname=y

现在，如果我更改 method =post，则上述方法不起作用。如何以编程方式提交 post 请求，然后将 print 生成的页面提交到 console ？

Now, if I change method="post" then the above method does not work. How can I submit the post request programatically and then print the resulting page to console ?

我试图使用很多方法。例如

I tried to use many methods . For example

PostMethod post = new PostMethod("http://www.w3schools.com/tags/demo_form_method.asp");
        NameValuePair[] data = {
          new NameValuePair("fname", "x"),
          new NameValuePair("lname", "y")
        };
        post.setRequestBody(data);

        ...
        InputStream in = post.getResponseBodyAsStream();
