Java发送https请求并跳过ssl证书验证方法

平台服务调用https接口报错:

org.springframework.web.client.ResourceAccessException: I/0 error on PoST request for ?"https://XXXXX": Java.security.centp.CertificateException: No subject alternative names present; nested exception is javax.net.ssl..SSLHandshakeException: java.security.cert.CertificateException: No subjec编程客栈t alternative namesspresent

第一种方法:配置相关SSL证书到服务器

第二种方法:如果没有相关服务器权限,又想快速验证接口编程调用,可以在请求时添加跳过SSL证书,可以 快捷实现,当然生产环境还是建议配置证书方式,降低风险

/**

    public static String sendAskSkipSSLCertificate(String url, Map<String, Object> body, Map<String, String> header) throws Exception {

        CloseableHttpResponse response = null;
        // 处理请求路径
        url = UriComponwww.devze.comentsBuilder.fromHttpUrl(url) .toUriString();
        //创建httpclient对象
        CloseableHttpClient client = null;
        String respBody;
        client = HttpClients.custom().setSSLSocketFactory(new SSLConnectionSocketFactory(SSLContexts.custom()
                        .loadTrustMaterial(null, new TrustSelfSignedStrphpategy()).build(), NoopHostnameVerifier.INSTANCE)).build();
        //创建post方式请求对象
        HttpPost httpPost = new HttpPost(url);
        // 请求头设置
        httpPost.setHeader("Content-Type", "application/json");
        if (header != null) {
            for (String s : header.keySet()) {
                httpPost.setHeader(s, header.get(s));
            }
        }
        if (body != null) {
            httpPost.setEntity(new StringEntity(JSON.toJSONString(body), "utf-8"));
        }
        response = client.execute(httpPost);
        org.apache.http.HttpEntity entity = response.getEntity();
        if (entity != null) {
            respBody = EntityUtils.toString(entity);
            return respBody;
        }
        return null;
 }

附：Java直接调用HTTP接口，并且获取List出参,输出数据List

1.代码实现 

public WrapperResponse<List<WarningDTO>> queryBigWarning(WarnInfoBInfoQueryDTO warnInfoBInfoQueryDTO) throws Exception {
    String SERVICE_URL = "http://127.0.0.1:8889/wakljfa";
        //发送httpPost请求
        //创建HttpClient
        HttpClient httpclient = HttpClients.createDefault();
        //发送接口地址
        HttpPost httppost = new HttpPost(SERVICE_URL);
        //定义String请求Json参数体
        httppost.setEntity(new StringEntity(new String("{" +
                "\"pageNum\": \"" + warnInfoBInfoQueryDTO.getPageNum() + "\"," +
                "\"pageSize\": \"" + warnInfoBInfoQueryDTO.getPageSize() + "\"," +
                "\"warnType\": \"" + warnInfoBInfoQueryDTO.getWarnType() + "\"" +
                "}"), Charset.forName("UTF-8")));

        httppost.setHeader("Content-Type", "application/json");
        //发送请求并接收response
        HttpResponse httpresponse = httpclient.execute(httppost);
        String result = EntityUtils.toString(httpresponse.getEntity(), "UTF-8");

        ObjectMapper objectMapper = new ObjectMapper();
        JsonNode responseJson = objectMapper.readTree(result);
        // 从JSON对象中获取键值对,根据出参格式获取出参数据
        JsonNode data = responseJson.get("data");
        JsonNode listWarn = pageInfo.get("list");

        Iterator<JsonNode> iterator = listWarn.iterator();
        List<WarningDTO> warningDTOS = new ArrayList<>();
        while (iterator.hasNext()) {
            WarningDTO warningDTO = new WarningDTO();
            JsonNode warningNode =  iterator.next();
            String warnOcurTime= warningNode.get("warnOcurTime").asText();
            warningDTO.setWarnOcurTime(warnOcurTime);
            String warnId= warningNode.get("warnId").asText();
            warningDTO.setWarnId( warnId);
            String id= warningNode.get("id").asText();
            pythonwarningDTO.setId( Id);
            warningDTOS.add(warningDTO);
        }
        return WrapperResponse.success(warningDTOS);
}

2.出参模式

"data": {
			"list": [
				{
					"warnId": "000000000000000000000000000201",
					"warnOcurTime": 1672502400000,
					"id": "000000000000000000000000000201"
				},
				{
					"warnId": "000000000000000000000000000301",
					"warnOcurTime": 1672502400000,
	                "id": "000000000000000000000000000301"
				}
			]
}
