HTTPS中内部访问

报错信息如下：

可以在请求时获取忽略证书验证的client

方法如下：

/**
     * 获取忽略证书验证的client
     *
     * @return
     * @throws Exception
     */
    public static CloseableHttpClient getIgnoeSSLClient() throws Exception {
        SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(null, new TrustStrategy() {
            @Override
            public boolean isTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
                return true;
            }
        }).build();

        //创建httpClient
        CloseableHttpClient client = HttpClients.custom().setSSLContext(sslContext).
                setSSLHostnameVerifier(new NoopHostnameVerifier()).build();
        return client;
    }

调用时使用：

public static String doGet(String url, Map<String, String> param) throws Exception {

        // 创建Httpclient对象
        CloseableHttpClient httpclient = getIgnoeSSLClient();
//        CloseableHttpClient httpclient = HttpClients.createDefault();

        String resultString = "";
        CloseableHttpResponse response = null;
        try {
            // 创建uri
            URIBuilder builder = new URIBuilder(url);
            if (param != null) {
                for (String key : param.keySet()) {
                    builder.addParameter(key, param.get(key));
                }
            }
            URI uri = builder.build();
            logger.error("get地址为:"+url+"********************************************");
            // 创建http GET请求
            HttpGet httpGet = new HttpGet(uri);

            // 执行请求
            response = httpclient.execute(httpGet);
            // 判断返回状态是否为200
            if (response.getStatusLine().getStatusCode() == 200) {
                resultString = EntityUtils.toString(response.getEntity(), "UTF-8");
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (response != null) {
                    response.close();
                }
                httpclient.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return resultString;
    }

    public static String doGet(String url) throws Exception {
        return doGet(url, null);
    }

    public static String doPost(String url) throws Exception {
        return doPost(url, null);
    }
    
    public static String doPost(String url, Map<String, String> param) throws Exception {
        // 创建Httpclient对象
        CloseableHttpClient httpClient = getIgnoeSSLClient();
//        CloseableHttpClient httpClient = HttpClients.createDefault();
        CloseableHttpResponse response = null;
        String resultString = "";
        try {
            // 创建Http Post请求
            HttpPost httpPost = new HttpPost(url);
            logger.error("post地址为:"+url+"********************************************");
            // 创建参数列表
            if (param != null) {
                List<NameValuePair> paramList = new ArrayList<>();
                for (String key : param.keySet()) {
                    paramList.add(new BasicNameValuePair(key, param.get(key)));
                }
                // 模拟表单
                UrlEncodedFormEntity entity = new UrlEncodedFormEntity(paramList);
                httpPost.setEntity(entity);
            }
            // 执行http请求
            response = httpClient.execute(httpPost);
            resultString = EntityUtils.toString(response.getEntity(), "utf-8");
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                response.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return resultString;
    }

这样就可以正常访问方法了
