httpClient发送https请求报错认证失败确少SSL证书的问题

报错内容

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

解决办法
1NG做跳转处理，先将https请求改为向ng发送http请求，ng做跳板发送https请求

server {listen       80;server_name _;return 301 https://$host$request_uri;
}

解决办法2
服务端配置跳过ssl认证

 HttpPost post = new HttpPost(url);//创建CloseableHttpClient对象-忽略SSL证书CloseableHttpClient client = null;try {SSLConnectionSocketFactory scsf = new SSLConnectionSocketFactory(SSLContexts.custom().loadTrustMaterial(null, new TrustSelfSignedStrategy()).build(),NoopHostnameVerifier.INSTANCE);client = HttpClients.custom().setSSLSocketFactory(scsf).build();} catch (KeyManagementException e) {logger.error("调用接口失败:",e);} catch (NoSuchAlgorithmException e) {logger.error("调用接口失败:",e);} catch (KeyStoreException e) {logger.error("调用接口失败:",e);}RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(connectTimeout).setSocketTimeout(socketTimeout).build();post.setConfig(requestConfig);ByteArrayEntity entity = new ByteArrayEntity(data.getBytes(StandardCharsets.UTF_8));entity.setContentType("application/json");post.setEntity(entity);CloseableHttpResponse res = client.execute(post);
