Https请求忽略证书验证最新实现

最近工作中需要和一个第三方公司进行https交互请求，但是对方的证书有一些问题，所以在发送请求的时候需要忽略证书验证。百度之后，发现已经有很多这方面的介绍，不过在使用其代码的时候总会有一些类不推荐使用了。下面是参考网上的常见方面并结合最新的官方API实现的一个最新方法（使用的主要jar包括httpclient-4.5.1.jar和httpcore-4.4.3.jar）。

	public static List doPostByClient(String url, Map postData, Map header,
			String encoding, long connectionTimeout, long soTimeout,boolean isNoSSL)
			throws Exception {

		CloseableHttpClient client = HttpClients.createDefault();
		if(isNoSSL)
		{
			client = (CloseableHttpClient)wrapClient(client);
		}

		HttpPost httpPost = new HttpPost(url);
		RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout((int) soTimeout).setConnectTimeout((int) connectionTimeout).build();//设置请求和传输超时时
		httpPost.setConfig(requestConfig);

		// 头部请求信息
		if (header != null) {
			Set entrySet = header.entrySet();
			for (Iterator itor = entrySet.iterator(); itor.hasNext();) {
				Map.Entry entry = (Map.Entry) itor.next();
				httpPost.addHeader(entry.getKey().toString(), entry.getValue()
						.toString());
			}
		}

		List parameters = new ArrayList();

		if (postData != null) {

			Set entrySet = postData.entrySet();

			for (Iterator itor = entrySet.iterator(); itor.hasNext();) {

				Map.Entry entry = (Map.Entry) itor.next();

				parameters.add(new BasicNameValuePair(
						entry.getKey().toString(), entry.getValue() + ""));

			}

			// 创建UrlEncodedFormEntity对象
			UrlEncodedFormEntity formEntiry = new UrlEncodedFormEntity(
					parameters, encoding);
			
			httpPost.setEntity(formEntiry);
		}

		// 执行请求

		HttpResponse response = client.execute(httpPost);

		response.getStatusLine();

		StatusLine status = response.getStatusLine();

		int sc = status.getStatusCode();

		if (sc != 200) {
			return null;
		}

		HttpEntity entity = response.getEntity();

		if (entity != null) {

			InputStream is = entity.getContent();

			BufferedReader bin = new BufferedReader(new InputStreamReader(is,
					"utf-8"), 1024 * 1024);
			List result = new ArrayList();
			while (true) {
				String line = bin.readLine();
				if (line == null) {
					break;
				} else {
					result.add(line);
				}
			}
			return (result);
		} else {
			return null;
		}
	}
	
	/**
	 * 避免HttpClient的”SSLPeerUnverifiedException: peer not authenticated”异常
	 * 不用导入SSL证书
	 * @param base
	 * @return
	 */
	public static HttpClient wrapClient(HttpClient base) {
		try {
			SSLContext ctx = SSLContext.getInstance("TLS");
			X509TrustManager tm = new X509TrustManager() {
				public X509Certificate[] getAcceptedIssuers() {
					return null;
				}

				public void checkClientTrusted(X509Certificate[] arg0,
						String arg1) throws CertificateException {
				}

				public void checkServerTrusted(X509Certificate[] arg0,
						String arg1) throws CertificateException {
				}
			};
			ctx.init(null, new TrustManager[] { tm }, null);
			SSLConnectionSocketFactory ssf = new SSLConnectionSocketFactory(ctx,NoopHostnameVerifier.INSTANCE);
			CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(ssf).build();
			return httpclient;
		} catch (Exception ex) {
			ex.printStackTrace();
			return HttpClients.createDefault();
		}
	}

说明：其中wrapClient方法就是创建一个不进行正式验证的请求客户端对象。
