用httpPost对JSON发送和接收的例子
private?static?final?String?APPLICATION_JSON?=?"application/json";
????????private?static?final?String?CONTENT_TYPE_TEXT_JSON?=?"text/json";
public?static?void?httpPostWithJSON(String?url,?String?json)?throws?Exception?{
????????//?将JSON进行UTF-8编码,以便传输中文????????String?encoderJson?=?URLEncoder.encode(json,?HTTP.UTF_8);????????????????DefaultHttpClient?httpClient?=?new?DefaultHttpClient();????????HttpPost?httpPost?=?new?HttpPost(url);????????httpPost.addHeader(HTTP.CONTENT_TYPE,?APPLICATION_JSON);????????????????StringEntity?se?=?new?StringEntity(encoderJson);????????se.setContentType(CONTENT_TYPE_TEXT_JSON);????????se.setContentEncoding(new?BasicHeader(HTTP.CONTENT_TYPE,?APPLICATION_JSON));????????httpPost.setEntity(se);????????httpClient.execute(httpPost);
????}
接收HTTPPost中的JSON:
public?static?String?receivePost(HttpServletRequest?request)?throws?IOException,?UnsupportedEncodingException?{????????????????//?读取请求内容????????BufferedReader?br?=?new?BufferedReader(new?InputStreamReader(request.getInputStream()));????????String?line?=?null;????????StringBuilder?sb?=?new?StringBuilder();
????????while((line?=?br.readLine())!=null){????????????sb.append(line);
????????}????????//?将资料解码????????String?reqBody?=?sb.toString();????????return?URLDecoder.decode(reqBody,?HTTP.UTF_8);????}转：http://www.blogjava.net/duansky/archive/2012/03/18/372137.html
