编写代码以获取响应
HttpResponse response = httpClient.execute(httpPost);
System.out.println("response after fetch "+response.toString());
BufferedReader reader = new BufferedReader(
new InputStreamReader(response.getEntity()
.getContent(), "UTF-8"));
StringBuffer responseString = new StringBuffer("");
String line;
while ((line = reader.readLine()) != null) {
responseString.append(line);
}
