解决https，javax.net.ssl.SSLException: hostname in certificate didn‘t match 等问题

问题原因：https链接需要验证证书，证书不匹配、过期等问题导致调用接口不成功

https不校验证书，代码：

    static {
        SSLSocketFactory socketFactory = new SSLSocketFactory(getSSLContext(), SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

        SchemeRegistry schemeRegistry = new SchemeRegistry();
        schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        schemeRegistry.register(new Scheme("https", socketFactory, 443));

        HttpParams params = new BasicHttpParams();
        params.setIntParameter(ConnManagerPNames.MAX_TOTAL_CONNECTIONS, 100);
        ConnPerRouteBean connPerRouteBean = new ConnPerRouteBean(100);
        params.setParameter(ConnManagerPNames.MAX_CONNECTIONS_PER_ROUTE, connPerRouteBean);

        connectionManager = new ThreadSafeClientConnManager(params, schemeRegistry);
    }

    private static SSLContext getSSLContext() {
        try {
            // 这里可以填两种值 TLS和LLS , 具体差别可以自行搜索
            SSLContext sc = SSLContext.getInstance("TLS");
            // 构建新对象
            X509TrustManager manager = new X509TrustManager() {
                @Override
                public void checkClientTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
                }

                @Override
                public void checkServerTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
                }

                // 这里返回Null
                @Override
                public X509Certificate[] getAcceptedIssuers() {
                    return null;
                }
            };
            sc.init(null, new TrustManager[]{manager}, null);
            return sc;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
