钉钉开放平台demo调试异常问题解决：hostname in certificate didn't match

今天研究钉钉的开放平台，结果一个demo整了半天，这帮助系统写的也很难懂。遇到两个问题：

 

1、首先是执行demo时报unable to find valid certification path to requested target，错误信息如下：

request url=https://oapi.dingtalk.com/gettoken?corpid=...略...&corpsecret=...略..., exception, msg=sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

只不过经研究，按网上的方式将证书导致到信任库中也没用，于是就找了段代码直接跳过

2、但是报下面这个错：

request url=https://oapi.dingtalk.com/get_jsapi_ticket?type=jsapi&access_token=2458f4d239173a12809cc94d1915d3b7,
exception, msg=hostname in certificate didn't match: <oapi.dingtalk.com> != <*.laiwang.com> OR <*.laiwang.com>

具体没空研究，找到下面代码解决：

    private static CloseableHttpClient getHttpClient() {
        RegistryBuilder<ConnectionSocketFactory> registryBuilder = RegistryBuilder.<ConnectionSocketFactory>create();
        ConnectionSocketFactory plainSF = new PlainConnectionSocketFactory();
        registryBuilder.register("http", plainSF);
        //指定信任密钥存储对象和连接套接字工厂
        try {
            KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
            //信任任何链接
            TrustStrategy anyTrustStrategy = new TrustStrategy() {
                @Override
                public boolean isTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
                    return true;
                }
            };
            SSLContext sslContext = SSLContexts.custom().useTLS().loadTrustMaterial(trustStore, anyTrustStrategy).build();
            LayeredConnectionSocketFactory sslSF = new SSLConnectionSocketFactory(sslContext, SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
            registryBuilder.register("https", sslSF);
        } catch (KeyStoreException e) {
            throw new RuntimeException(e);
        } catch (KeyManagementException e) {
            throw new RuntimeException(e);
        } catch (NoSuchAlgorithmException e) {
            throw new RuntimeException(e);
        }
        Registry<ConnectionSocketFactory> registry = registryBuilder.build();
        //设置连接管理器
        PoolingHttpClientConnectionManager connManager = new PoolingHttpClientConnectionManager(registry);
//        connManager.setDefaultConnectionConfig(connConfig);
//        connManager.setDefaultSocketConfig(socketConfig);
        //构建客户端
        return HttpClientBuilder.create().setConnectionManager(connManager).build();
    }
