推荐答案

您可以使用 HttpClient 执行 HTTP GET 并检索 HTML 响应，如下所示:

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();
