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，一般下芙囹买乐载下来有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")稆糨孝汶;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！
