Jsoup抓取Https出现unable to find valid certification path to requested target

解决办法如下：

方法一：

1. 增加前置初始化操作

static public void init() {
        try {
            SSLContext context = SSLContext.getInstance("TLS");
            context.init(null, new X509TrustManager[]{new X509TrustManager() {
                public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                }

                public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                }

                public X509Certificate[] getAcceptedIssuers() {
                    return new X509Certificate[0];
                }
            }}, new SecureRandom());
            HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

2. 在进行网站抓取

 public static void main(String[] args) throws Exception {
        String url = "https://info.hebei.gov.cn/hbszfxxgk/6898876/6898925/6899014/6906934/748af770/index1.html";
        init();
        String UA = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/93.0.4577.63 Safari/537.36";
        Document countDocument = Jsoup.connect(url).timeout(30000).userAgent(UA).get();
        System.out.println(countDocument);
    }

方法二：使用httpUtil请求抓取网页结果

 //首先使用工具类获取一下网页结构
 String strHtml = HttpUtil.get(url, 30000);
 //在用JSOUP解析HTML结构
 Document countDocument = Jsoup.parse(strHtml);
