Send the POST Params call

Keyval params form Map<String, Object> mp = new HashMap<String, Object>(); mp.put("params", 123); String sr1 = HttpRequestUitlTest.sendPostParams("http://localhost:9996/getTest1", mp); System.out.println(sr1);Copy the code

Send post params

/** * @param url * @param params ** @return */ public static String sendPostParams(String url, Map params) { BufferedReader in = null; Try {// define HttpClient HttpClient client = new DefaultHttpClient(); // Instantiate the HTTP method HttpPost request = new HttpPost(); request.setURI(new URI(url)); NVPS = new ArrayList<NameValuePair>(); for (Iterator iter = params.keySet().iterator(); iter.hasNext();) { String name = (String) iter.next(); String value = String.valueOf(params.get(name)); nvps.add(new BasicNameValuePair(name, value)); // System.out.println(name +"-"+value); } request.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8)); HttpResponse response = client.execute(request); int code = response.getStatusLine().getStatusCode(); If (code == 200) {// Request success in = new InputStreamReader(new InputStreamReader(response.getentity ().getContent(), "UTF-8 ")); StringBuffer sb = new StringBuffer(""); String line = ""; String NL = System.getProperty("line.separator"); while ((line = in.readLine()) ! = null) { sb.append(line + NL); } in.close(); return sb.toString(); } else {// system.out.println (" status code: "+ code); return null; } } catch (Exception e) { e.printStackTrace(); return null; }}Copy the code
