JAVA微信企业付款如何使用证书、证书调用实例

1、下载微信商户证书，一般下载下来有4个文件用.p12的文件即可。名称例如下：apiclient_cert.p12

2、下载完证书之后保存到计算任何盘里，最好不要用中文路径

3、开发时调用证书主要是调用API在发送POST请求时使用。

4、代码如下：修改证书路径跟密码即可

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

FileInputStream instream = new FileInputStream(new File("证书路径如（D://aa.p12）"));

 keyStore.load(instream, "证书密码（初始是商户 ID）".toCharArray());//杩欓噷鍐欏

 instream.close();

SSLContext sslcontext = SSLContexts.custom().loadKeyMaterial(keyStore, "证书密码（初始是商户 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); // 璁剧疆鍝嶅簲澶翠俊鎭?

        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);

5、将以上代码封装到mothod里即可。

6、调用，直接调用方法。参数自己封装！
