android HTTP发送及MD5加密收集
发送部分:
public void MyFunction{ HttpClient httpclient = new DefaultHttpClient(); //你的URL HttpPost httppost = new HttpPost("http://www.eoeandroid.com/post_datas.php"); try { List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2); //Your DATA nameValuePairs.add(new BasicNameValuePair("id", "12345")); nameValuePairs.add(new BasicNameValuePair("stringdata", "eoeAndroid.com is Cool!")); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); HttpResponse response; response=httpclient.execute(httppost); } catch (ClientProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } }
MD5加密部分:
public static String md5(String string) { byte[] hash; try { hash = MessageDigest.getInstance("MD5").digest(string.getBytes("UTF-8")); } catch (NoSuchAlgorithmException e) { throw new RuntimeException("Huh, MD5 should be supported?", e); } catch (UnsupportedEncodingException e) { throw new RuntimeException("Huh, UTF-8 should be supported?", e); } StringBuilder hex = new StringBuilder(hash.length * 2); for (byte b : hash) { if ((b & 0xFF) < 0x10) hex.append("0"); hex.append(Integer.toHexString(b & 0xFF)); } return hex.toString(); }
