java - Java 下载 html

Question

我正在尝试下载网站的 html：

    String encoding = "UTF-8";

HttpContext localContext = new BasicHttpContext();

    HttpClient httpclient = new DefaultHttpClient();

HttpGet httpget = new HttpGet(MYURL);

httpget.setHeader("User-Agent", "Mozilla/5.0 (iPhone; CPU iPhone OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A334 Safari/7534.48.3");


HttpResponse response = httpclient.execute(httpget, localContext);

HttpEntity entity = response.getEntity();

InputStream instream = entity.getContent();

String html = getStringFromInputStream(encoding, instream);

在 html 字符串的 and 中，我得到：

...
21912
0
0

而且我没有得到完整的html，知道如何解决吗？

编辑

private static String getStringFromInputStream(String encoding, InputStream instream) throws UnsupportedEncodingException, IOException {

Writer writer = new StringWriter();


char[] buffer = new char[1024];

try {

Reader reader = new BufferedReader(new InputStreamReader(instream, encoding));

int n;

while ((n = reader.read(buffer)) != -1) {

writer.write(buffer, 0, n);

}

} finally {

instream.close();

}

String result = writer.toString();

return result;
}

我建议宁可使用EntityUtils：

HttpEntity entity = response.getEntity();
String html = EntityUtils.toString(entity);

或者

HttpEntity entity = response.getEntity();
String html = EntityUtils.toString(entity, encoding);
