代碼如下：修改證書路徑跟密碼即可

KeyStore keyStore ?= KeyStore.getInstance("PKCS12");

FileInputStream instream = new FileInputStream(new File("證書路徑如(D://aa.p12)"));

keyStore.load(instream, "證書密碼(初始是商戶 ID)".toCharArray());//榪欓噷鍐欏

instream.close();

SSLContext sslcontext = SSLContexts.custom().loadKeyMaterial(keyStore, "證書密碼(初始是商戶 ID)".toCharArray()).build();

SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslcontext,new String[] { "TLSv1" },null,

SSLConnectionSocketFactory.BROWSER_COMPATIBLE_HOSTNAME_VERIFIER);

CloseableHttpClient httpclient = HttpClients.custom() .setSSLSocketFactory(sslsf) .build();

HttpPost httpost = new HttpPost(url); // 璁劇疆鍝嶅簲澶翠俊鎭?

httpost.addHeader("Connection", "keep-alive");

httpost.addHeader("Accept", "*/*");

httpost.addHeader("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");

httpost.addHeader("Host", "api.mch.weixin.qq.com");

httpost.addHeader("X-Requested-With", "XMLHttpRequest");

httpost.addHeader("Cache-Control", "max-age=0");

httpost.addHeader("User-Agent", "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0) ");

httpost.setEntity(new StringEntity(data, "UTF-8"));

CloseableHttpResponse response = httpclient.execute(httpost);

HttpEntity entity = response.getEntity();

String jsonStr = EntityUtils .toString(response.getEntity(), "UTF-8");

EntityUtils.consume(entity);
