我工作，需要从一个链接的网页的源，然后解析来自该网页的HTML的应用程序。

I'm working on an application that needs to get the source of a web page from a link, and then parse the html from that page.

你能不能给我一些例子，或启动点到哪里开始写这样的应用程序？

Could you give me some examples, or starting points where to look to start writing such an app?

推荐答案

您可以使用HttpClient执行HTTP GET和检索HTML的响应，是这样的：

You can use HttpClient to perform an HTTP GET and retrieve the HTML response, something like this:

HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(url);
HttpResponse response = client.execute(request);

String html = "";
InputStream in = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder str = new StringBuilder();
String line = null;
while((line = reader.readLine()) != null)
{
    str.append(line);
}
in.close();
html = str.toString();
