Android解析socket或http流中文編碼問題

這裏直接拿了HTTP流實驗了下

複製到剪貼板  Java代碼

public String getHttpContent(String htmlUrl) throws IOException,
   InterruptedException {
  URL url;
  InputStream is = null;
  HttpURLConnection urlConn = null;
  int count = 0;
  ByteArrayOutputStream baos = new ByteArrayOutputStream();
  try {
   url = new URL(htmlUrl);
   urlConn = (HttpURLConnection) url.openConnection();

   urlConn.setConnectTimeout(20000);
   urlConn.setReadTimeout(20000);
   is = urlConn.getInputStream();

   byte[] buf = new byte[512];
   int ch = -1;
   while ((ch = is.read(buf)) != -1) {
    baos.write(buf, 0, ch);
    count = count + ch;
   }

  } catch (final MalformedURLException me) {
   me.getMessage();
   throw me;
  } catch (final IOException e) {
   e.printStackTrace();
   throw e;
  }
   return new String(baos.toByteArray(), "GB2312");
 }

其實上面的方法很簡單，剛開始那哥們用的BufferedReader去讀，這樣直接讀出來String有問題，解碼不對，後來自己讀到 byteoutputstream裏，然後讀出字節自己手工編碼就對了，可是昨天晚上發現了一個更簡單的方法，我們真是走了一個大大的彎路，如下：

Java代碼

public String getHttpContent(String htmlurl) throws Exception{
  HttpClient hc = new DefaultHttpClient();

  HttpGet get = new HttpGet(htmlUrl);
  HttpResponse rp = hc.execute(get);

  if (rp.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {

  return EntityUtils.toString(rp.getEntity()).trim();

  }else{

  return null;

  }

}

apache的這些類用起來還真是方便，以後還要多多學習。
