用自定义ip获取url数据

public static String jsoupEntity(String url1) {
        InputStream is = null;
        BufferedReader buffer = null;
        try {
            String[] ips = newIp();//获取自定义ip  127.0.0.1:80 split
            if (null == ips) return null;
            Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(ips[0], Integer.parseInt(ips[1])));
            URL url = new URL(url1);
            if (url1.startsWith("https")) {
                HttpsURLConnection urlcon = (HttpsURLConnection) url.openConnection(proxy);
                urlcon.setRequestMethod("GET");
                urlcon.setConnectTimeout(1000);
                urlcon.connect();
                is = urlcon.getInputStream();
