Question

出于某种原因，使用Htmlunit正确导入所有内容的代码会导致错误。

package htmlunittesting;

import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlAnchor;
import com.gargoylesoftware.htmlunit.html.HtmlDivision;
import com.gargoylesoftware.htmlunit.html.HtmlPage;

public class httpunittest {

public static void main(String[] args) throws Exception{
    final WebClient webClient = new WebClient();
    final HtmlPage page = webClient.getPage("https://blockchain.info/address/17iyEdbcG3G6RrDHYsi2MzG6RY8vRYvjXm");
    final HtmlDivision div = page.getHtmlElementById("final_balance");
   // final HtmlAnchor anchor = page.getAnchorByName("anchor_name");

    System.out.println(div);

    webClient.closeAllWindows();
}
}

我的错误是：

 Caused by: java.security.cert.CertificateException: No X509TrustManager implementation available
at sun.security.ssl.DummyX509TrustManager.checkServerTrusted(Unknown Source)
... 27 more

我想要做的就是打印出这个测试钱包的最终余额。

按要求填写整个StackTrace：

是的，这就是我的所有代码，没有其他类。

您应该将这些参数添加到java虚拟机：

        System.setProperty("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol");
        Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
        System.setProperty("javax.net.ssl.trustStoreType", "JKS");
        System.setProperty("javax.net.ssl.trustStore", "../path/yourtruststore.jks");
        System.setProperty("javax.net.ssl.trustStorePassword", "yourpasswordfortruststore");

如果您需要相互身份验证：

        System.setProperty("javax.net.ssl.keyStore","../path../yourkeystore.jks");
        System.setProperty("javax.net.ssl.keyStorePassword","yourpasswordforkeystore");
        System.setProperty("javax.net.ssl.keyStoreType", "JKS");

没有X509TrustManager实现可用htmlunit
