1、get
public static String doGet(String strUrl ){ String strReturn=""; HttpGet httpGet = new HttpGet(strUrl); CloseableHttpClient httpclient = null; CloseableHttpResponse response1=null; try { httpclient = HttpClients.createDefault(); response1 = httpclient.execute(httpGet); HttpEntity entity1 = response1.getEntity(); strReturn=EntityUtils.toString(entity1) ; EntityUtils.consume(entity1); }catch(Exception e){ e.printStackTrace(); }finally { try { if(response1!=null) response1.close(); } catch (IOException e) { e.printStackTrace(); } } return strReturn; }
2、put
public static String doPut(String strUrl,String param){ CloseableHttpClient httpclient = HttpClients.createDefault(); String strReturn=""; PutMethod httpput=new PutMethod(strUrl); try { if(param!=null) { RequestEntity entity = new StringRequestEntity(param, "application/json", "UTF-8"); httpput.setRequestEntity(entity); } httpClient.executeMethod(httpput); byte[] bytes = httpput.getResponseBody(); strReturn= new String(bytes) ; } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return strReturn; }
3、post
public static String doPost(String requestUrl, String payload) { CloseableHttpClient httpclient = HttpClients.createDefault(); String strReturn=""; PostMethod httpost = new PostMethod(requestUrl); try { if(payload!=null) { RequestEntity entity = new StringRequestEntity(payload, "application/json", "UTF-8"); httpost.setRequestEntity(entity); } httpClient.executeMethod(httpost); byte[] bytes = httpost.getResponseBody(); strReturn= new String(bytes) ; } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return strReturn; }
4、delete
public static void doDelete(String urlToRead) throws Exception { URL url = new URL(urlToRead); HttpURLConnection httpCon = (HttpURLConnection) url.openConnection(); httpCon.setDoOutput(true); httpCon.setRequestProperty( "Content-Type", "application/x-www-form-urlencoded" ); httpCon.setRequestMethod("DELETE"); httpCon.connect(); httpCon.disconnect(); }
