java - htmlunit-2.7-java.net.SocketException : Connection reset

Question

我正在尝试使用 htmlunit-2.7 库(这是 SoapUI-5.2.1 中可用的默认库)来自动化用户级 token 检索过程(OAuth2 的授权代码授予流程)。但当我尝试通过 htmlunit-2.7 的 WebClient 类连接到 Google Page 时，收到连接重置错误。

下面是我的代码，

我在项目中使用的依赖 Jar 文件，

commons-codec-1.3.jarcommons-httpclient-3.1.jarcommons-io-2.4.jarcommons-lang-2.4.jarcommons-logging-1.1.1.jarhtmlunit-2.7.jarhtmlunit-core-js-2.7.jarsac-1.3.jarxercesImpl-2.9.1.jar

import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlForm;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.gargoylesoftware.htmlunit.html.HtmlSubmitInput;
import com.gargoylesoftware.htmlunit.html.HtmlTextInput;

public class HTMLUnitClass 
{

    public static void main(String[] args) 
    {
        // TODO Auto-generated method stub


        System.out.println("Starting the  Script");

        try
         {
          //Webpage Login  
            WebClient driver = new WebClient();
            System.out.println("Instantiating the WebClient");


            driver.setJavaScriptEnabled(true);
            System.out.println("Enabling the Java Script");
            driver.setThrowExceptionOnScriptError(false);
            System.out.println("Disabling the Throw Exception on Script Error");


            try
            {
                driver.getPage("https://www.google.com");
                System.out.println("Getting the Google Page");

            }
            catch(Exception e)
            {
                System.out.println("Exception in the HTML Unit Driver Block: " + e);
            }


            }
            catch (Exception e)
            {
                System.out.println("Exception in the HTTPClient Block" + e);
            }




    }

}

我收到以下错误 - 堆栈如下，

NOTE-1: Please note that, I cannot go with the latest HtmlUnitDriver Library (Jar), because that will cause version conflicts with the default libraries of the SoapUI-5.2.1 That is the reason for me to stick to the Default Libraries provided in the Installation package of SoapUI-5.2.1 and trying to integrate this solution with the Groovy Script available in one of the Test Steps of the SoapUI.

NOTE-2: I tried using the Apache OAuth Client 2.0 Library as well for automating the Level Token Generation (My Clarification on OAuth Client 2.0 Library)

有人可以阐明如何解决此连接重置问题吗？

Answer 1

我自己也遇到了同样的问题，正确的解决方案是@canpan14在第一条评论中提出的解决方案

我克服此错误的解决方案如下:

WebClient webClient = new WebClient(BEST_SUPPORTED);
webClient.getOptions().setUseInsecureSSL(true); //ignore insecure ssl exception
webClient.getOptions().setSSLClientProtocols(new String[] { "TLSv1.2","TLSv1.1" });

最后一行代码实际上设置要使用的 TLS 类型。为了使您的代码正常工作，首选 TLSv1.2。
