已知证书的情况下，添加带证书认证请求

 今天在做开发时候，遇到对方在提供了证书文件如：****.jks,或*****.store文件时候，我们如何生成带证书签名的请求。

 

首先，在请求中会用到二个重要的类HttpsURLConnection和密钥管理类KeyManager，这两个类大家可以谷哥或度娘查看具体介绍。

 

不多说，直接上实现类

import java.io.InputStreamReader;

		KeyManagerFactory keyManagerFactory = initKeyManagerFactory(ks, "你的证书密码");	
		SSLContext ssf = initSSLContext(keyManagerFactory.getKeyManagers(), null, new SecureRandom());
		URL url = new URL("你的https地址");
		HttpsURLConnection httpsConn = (HttpsURLConnection) url.openConnection();
		httpsConn.setSSLSocketFactory(ssf.getSocketFactory());
		httpsConn.setRequestMethod("POST"); 
		httpsConn.setDoOutput(true); 
		httpsConn.setDoInput(true);
		InputStreamReader insr = new InputStreamReader(httpsConn.getInputStream());
		StringBuffer result = new StringBuffer();
		// 读取服务器的响应内容并显示
		int respInt = insr.read();
		while (respInt != -1) {
			result.append((char) respInt);
			respInt = insr.read();
		}
		System.out.println(result.toString());
	}
