httpClient 4.32 帶認證的用法 

public static String httpPost(String url) throws Exception{
	
		String host = WebRTCPropertyManager.getValue("HOST");
		String user = WebRTCPropertyManager.getValue("USER");
		String password = WebRTCPropertyManager.getValue("PASSWORD");
		
		url="https://"+host+url;

		CloseableHttpClient httpClient = null;
		ConnectionConfig connConfig = ConnectionConfig.custom().setCharset(Charset.forName("utf-8")).build();
		KeyStore trustStore = null;
		SSLContext sslContext = null;
		trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
		sslContext = SSLContexts.custom().useTLS().loadTrustMaterial(trustStore, new AnyTrustStrategy()).build();
		SSLConnectionSocketFactory sslSF = new SSLConnectionSocketFactory(sslContext,SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

		CredentialsProvider credsProvider = new BasicCredentialsProvider();
		credsProvider.setCredentials(new AuthScope(AuthScope.ANY_HOST,AuthScope.ANY_PORT, AuthScope.ANY_SCHEME, AuthPolicy.BASIC),new UsernamePasswordCredentials(user, password));

		HttpClientBuilder hcb = HttpClientBuilder.create();
		hcb.setDefaultCredentialsProvider(credsProvider);

		httpClient = HttpClients.custom().setDefaultConnectionConfig(connConfig).setDefaultCredentialsProvider(credsProvider).setSSLSocketFactory(sslSF).build();

		HttpGet httpGet = new HttpGet(url);
		CloseableHttpResponse httpresponse = httpClient.execute(httpGet);

		String result = EntityUtils.toString(httpresponse.getEntity(), "UTF-8");
		
		return result;
		
	}
 

httpClient 4.3.1 普通寫法 

public static String httpPost(String url,String xml,String type){
		
		String result="";
		String dataType="text/xml";
		if(type.equalsIgnoreCase("json")){
			dataType="application/json";
		}
        HttpClient client= new HttpClient();
		PostMethod post= new PostMethod(url);
		RequestEntity re;
		try {
			re = new StringRequestEntity(xml, dataType, "UTF-8");
			post.setRequestEntity(re);
			client.executeMethod(post);
			result=post.getResponseBodyAsString();
			
		} catch (Exception e) {
			
			e.printStackTrace();
		}
