doGet,doPost与doPut读取方法

1.设置参数，使用协议读取https

public static void paramSettings(HttpClient httpclient){
		
       
		try {
			//Secure Protocol implementation.  
			SSLContext ctx = SSLContext.getInstance("SSL");
			
			//Implementation of a trust manager for X509 certificates  
	        X509TrustManager tm = new X509TrustManager() {  

	            public void checkClientTrusted(X509Certificate[] xcs,  
	                    String string) throws CertificateException {  

	            }  

	            public void checkServerTrusted(X509Certificate[] xcs,  
	                    String string) throws CertificateException {  
	            }  

	            public X509Certificate[] getAcceptedIssuers() {  
	                return null;  
	            }  
	        }; 
	        
	        X509HostnameVerifier hostnameVerifier = new X509HostnameVerifier(){

				public boolean verify(String hostname, SSLSession session) {
					// TODO Auto-generated method stub
					return true;
				}

				public void verify(String arg0, SSLSocket arg1)
						throws IOException {
					// TODO Auto-generated method stub
					
				}

				public void verify(String arg0, X509Certificate arg1)
						throws SSLException {
					// TODO Auto-generated method stub
					
				}

				public void verify(String arg0, String[] arg1, String[] arg2)
						throws SSLException {
					// TODO Auto-generated method stub
					
				} }; 
				
				 ctx.init(null, new TrustManager[] { tm }, null);  
			        SSLSocketFactory ssf = new SSLSocketFactory(ctx,hostnameVerifier);  
			        

			        ClientConnectionManager ccm = httpclient.getConnectionManager();  
			                    //register https protocol in httpclient's scheme registry  
			        SchemeRegistry sr = ccm.getSchemeRegistry();  
			        sr.register(new Scheme("https", 443, ssf));  
			        sr.register(new Scheme("http", 80,PlainSocketFactory
			                .getSocketFactory()));
			        
			        //set Time out
		            httpclient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, TIME_OUT); 
		            httpclient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, TIME_OUT); 
			        
		} catch (NoSuchAlgorithmException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (KeyManagementException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}  
        
             
	}

 

   

2.doGet

 

public static String getHTTPSJsonRequest(String url, String userName,
			String password) {
		logger.info("HttpsUtil : getHTTPSResult start............");
		String result = null;

		try {

			HttpClient httpclient = getHttpClient();

			HttpGet httpget = new HttpGet(url);

			String authString = userName + ":" + password;
			String authStringEnc = new String(Base64.encode(authString
					.getBytes()));

			httpget.addHeader("Authorization", "Basic " + authStringEnc);
			httpget.addHeader("content-type", "application/json");

			ResponseHandler responseHandler = new BasicResponseHandler();

			result = httpclient.execute(httpget, responseHandler);

			logger.debug("HttpsUtil : getHTTPSResult;result = " + result);
			// Create a response handler
			httpget.releaseConnection();

		} catch (ClientProtocolException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

		logger.info("HttpsUtil : getHTTPSResult end........");
		return result;
	}

 

 3.doPut

public static String putHTTPSJsonRequest(String url) {
		logger.info("HttpsUtil : putHTTPSResult start............");
		logger.debug("url : " + url);
		String info = null;
		HttpClient httpclient = getHttpClient();

		HttpPut httpPut = new HttpPut(url);

		try {
			HttpResponse httpresponse = httpclient.execute(httpPut);
			HttpEntity entity = httpresponse.getEntity();

			info = EntityUtils.toString(entity, "UTF-8");
			System.out.println("info = " + info);
			httpPut.addHeader("content-type", "application/json");
		} catch (Exception e) {
			logger.debug("putData Exception url:{}", url, e);

		} finally {
			httpPut.releaseConnection();

		}


		logger.info("HttpsUtil : putHTTPSResult end........");

		// return info;
		return info;
	}

 

 

4.doPost

public static String postHTTPSJsonRequest(String url,
			Map<String, String> params) {

		logger.info("HttpsUtil : postHTTPSResult start............");
		logger.debug("url : " + url);
		String response = null;
		String info = null;
		HttpClient httpclient = getHttpClient();

		HttpPost httpPost = new HttpPost(url);

		try {

			List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

			if (params != null && params.size() > 0) {
				Iterator keysIterator = params.keySet().iterator();

				while (keysIterator.hasNext()) {
					String key = (String) keysIterator.next();
					String value = params.get(key);

					nameValuePairs.add(new BasicNameValuePair(key, value));
				}
			}

			if (nameValuePairs != null && nameValuePairs.size() > 0) {
				httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs,
						"UTF-8"));
			}
			HttpResponse httpresponse = httpclient.execute(httpPost);
			HttpEntity entity = httpresponse.getEntity();

			info = EntityUtils.toString(entity, "UTF-8");
			System.out.println("info = " + info);
			httpPost.addHeader("content-type", "application/json");
		} catch (Exception e) {
			logger.debug("putData Exception url:{}", url, e);

		} finally {
			httpPost.releaseConnection();

		}


		logger.info("HttpsUtil : postHTTPSResult end........");

		return info;
	}

 

 

public static HttpClient getHttpClientWithSSL(String SSLPath) 
			throws KeyStoreException, NoSuchAlgorithmException, CertificateException, IOException, KeyManagementException, UnrecoverableKeyException{
		
		HttpClient httpclient = new DefaultHttpClient();
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType()); 
		FileInputStream instream = new FileInputStream(new File(SSLPath));
		try {
			trustStore.load(instream, "123456".toCharArray());
		} finally {
			instream.close();
		}
		SSLSocketFactory socketFactory = new SSLSocketFactory(trustStore,"123456",trustStore);
		Scheme sch = new Scheme("https", socketFactory, 443);
		httpclient.getConnectionManager().getSchemeRegistry().register(sch);

		
//		httpclient.getConnectionManager().shutdown();
		
		return httpclient;
