HTTPPost发送JSON

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);
    }
