HTTPPost發送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 {
// 將JSON進行UTF-8編碼,以便傳輸中文
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 {
// 讀取請求內容
BufferedReader br = new BufferedReader(new InputStreamReader(request.getInputStream()));
String line = null;
StringBuilder sb = new StringBuilder();
while((line = br.readLine())!=null){
sb.append(line);
}
// 將資料解碼
String reqBody = sb.toString();
return URLDecoder.decode(reqBody, HTTP.UTF_8);
}
