【问题描述】：

我正在尝试使用摘要授权进行 SOAP 活动。当我尝试连接到测试服务时，出现以下错误：

Exception in thread "main" org.apache.http.conn.HttpHostConnectException: Connect to httpbin.org:135 [httpbin.org/34.231.30.52, httpbin.org/54.166.163.67, httpbin.org/54.91.118.50, httpbin.org/34.199.75.4] failed: Connection timed out: connect

我为解决方案做了什么：

更改了端口号 更改了网址 更改了启动项目的 PC...没有任何帮助:(

如果有任何帮助，我将不胜感激。代码：

主要

public class Main 
    public static void main(String[] args) throws Exception 
        SOAPClientApache soapClientApache = new SOAPClientApache();
        soapClientApache.run();
    

【参考方案1】：

结果证明解决方案非常简单。 我已经为我设置了正确的端口

HttpHost target = new HttpHost(httpget.getURI().getHost(), 443, "https");

我还禁用了防火墙。
