用Java提交HTML表单 [英] Submit HTML Form in Java

问题描述

我试图填写HTML表单，按下表单的提交按钮，然后从中获得响应。

I am trying to fill in a HTML Form, press a submit button of the form and then get the response from it.

填写表单的效果非常好，但我无法弄清楚如何按下页面上的提交按钮。

Filling in the form works really well but i can't figure out how to press the submit button on the page.

我使用apache httpclient库。

I am using the apache httpclient libraries.

我的代码是：

My code is:

        httpclient = new DefaultHttpClient();
        HttpPost httpost = new HttpPost(pUrl);

        List <NameValuePair> nvps = new ArrayList <NameValuePair>();
        nvps.add(new BasicNameValuePair("filter_response_time_http", "1"));
        nvps.add(new BasicNameValuePair("filter_port", "80"));
        nvps.add(new BasicNameValuePair("filter_country", "US"));
        nvps.add(new BasicNameValuePair("submit", "Anzeigen"));

        httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));

        response = httpclient.execute(httpost);


        entity = response.getEntity();

提交按钮的代码为：

The code for the submit button is:

<input onclick="doSubmit();" id="submit" type="submit" value="Anzeigen" name="submit" /> 

推荐答案

你不用HttpClient ;它所做的只是HTTP东西，它与JS和DOM无关。

You don't "click a button" with HttpClient; all it does is HTTP stuff, which is unrelated to JS and the DOM.

如果您想模拟浏览器，请使用 JWebUnit ，它可以驱动HttpClient和Selenium，并提供JavaScript支持。

If you want to emulate a browser, use something like JWebUnit, which can drive both HttpClient and Selenium, and provides JavaScript support.
