https javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building f

原因：这是SSL证书请求问题。

原代码

private String postForAPP1(String token) throws Exception {

Map param = new HashMap();

TxnBodyCom txnBodyCom = new TxnBodyCom();

param.put("txnBodyCom", txnBodyCom);

// txnCom.setTxnBodyCom(txnBodyCom);

TxnCommCom txnCommCom = new TxnCommCom();

txnCommCom.setTRecInPage("1111");

txnCommCom.setTxnIttChnlCgyCode("1111");

txnCommCom.setTStsTraceId("=01111");

txnCommCom.setTPageJump("1111");

txnCommCom.setTxnIttChnlId("1111111");

param.put("txnCommCom", txnCommCom);

JSON.toJSONString(param);

CloseableHttpClient httpClient = HttpClients.createDefault();

RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(300 * 1000)

.setConnectTimeout(300 * 1000).build();

// 创建post方式请求对象

HttpPost post = new HttpPost("https://www.baidu.com:1111");

post.setConfig(requestConfig);

// 请求的数据包为raw，设置报文头为Content-Type

post.addHeader("Content-Type", "application/json;charset=utf-8");

post.addHeader("C-Tenancy-id", "11111");

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

post.addHeader("Referer", "https://www.baidu.com:1111");

post.addHeader("C-Dynamic-Password-Foruser", token);

post.addHeader("C-App-Id", "11111");

// 装载参数

StringEntity postingString = new StringEntity(JSON.toJSONString(param), "utf-8");

post.setEntity(postingString);

// 执行请求并拿到结果

HttpResponse response = null;

String content = null;

CloseableHttpClient client = null;

try {

// httpClient = buildSSLCloseableHttpClient();

response = httpClient.execute(post);

// 判断返回状态是否正常

int state = response.getStatusLine().getStatusCode();

// 获取结果实体并返回结果

org.apache.http.HttpEntity entity = response.getEntity();

content = EntityUtils.toString(entity);

return content;

} catch (Exception e) {

e.printStackTrace();

} finally {

httpClient.close();

}

return null;

}

报错javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

修改代码：新增一个方法，忽略主机名称验证

/**

* buildSSLCloseableHttpClient:(设置允许所有主机名称都可以，忽略主机名称验证)

* @author xbq

* @return

* @throws Exception

*/

private static CloseableHttpClient buildSSLCloseableHttpClient() throws Exception {

SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {

// 信任所有

public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {

return true;

}

}).build();

// ALLOW_ALL_HOSTNAME_VERIFIER:这个主机名验证器基本上是关闭主机名验证的,实现的是一个空操作，并且不会抛出javax.net.ssl.SSLException异常。

SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext, new String[] { "TLSv1.2" }, null,

SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

return HttpClients.custom().setSSLSocketFactory(sslsf).build();

}

在原代码处调用新增的方法

private String postForAPP1(String token) throws Exception {

Map param = new HashMap();

TxnBodyCom txnBodyCom = new TxnBodyCom();

param.put("txnBodyCom", txnBodyCom);

// txnCom.setTxnBodyCom(txnBodyCom);

TxnCommCom txnCommCom = new TxnCommCom();

txnCommCom.setTRecInPage("10");

txnCommCom.setTxnIttChnlCgyCode("111111");

txnCommCom.setTStsTraceId("1111111");

txnCommCom.setTPageJump("1");

txnCommCom.setTxnIttChnlId("1111");

param.put("txnCommCom", txnCommCom);

JSON.toJSONString(param);

CloseableHttpClient httpClient = HttpClients.createDefault();

RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(300 * 1000)

.setConnectTimeout(300 * 1000).build();

// 创建post方式请求对象

HttpPost post = new HttpPost("https://www.baudu.com");

post.setConfig(requestConfig);

// 请求的数据包为raw，设置报文头为Content-Type

post.addHeader("Content-Type", "application/json;charset=utf-8");

post.addHeader("C-Tenancy-id", "1111111");

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

post.addHeader("Referer", "https://www.baidu.com");

post.addHeader("C-Dynamic-Password-Foruser", token);

post.addHeader("C-App-Id", "11111111");

// 装载参数

StringEntity postingString = new StringEntity(JSON.toJSONString(param), "utf-8");

post.setEntity(postingString);

// 执行请求并拿到结果

HttpResponse response = null;

String content = null;

CloseableHttpClient client = null;

try {

//调用新方法

httpClient = buildSSLCloseableHttpClient();

response = httpClient.execute(post);

// 判断返回状态是否正常

int state = response.getStatusLine().getStatusCode();

// 获取结果实体并返回结果

org.apache.http.HttpEntity entity = response.getEntity();

content = EntityUtils.toString(entity);

return content;

} catch (Exception e) {

e.printStackTrace();

} finally {

httpClient.close();

}

return null;
