用httpPost对JSON发送和接收的例子
HTTPPost发送JSON：
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); }
