传输实体

1. UrlEncodedFormEntity()

List<NameValuePair> pairs = new ArrayList<NameValuePair>();  NameValuePair pair1 = new BasicNameValuePair("supervisor", supervisorEt.getEditableText().toString());      pairs.add(pair1);        httpPost.setEntity(new UrlEncodedFormEntity(pairs, HTTP.UTF_8));

1. StringEntity()
   httpPost.setEntity(new StringEntity(postData.toString(), HTTP.UTF_8));
