强制 java web 开始使用像 Fiddler 这样的代理，而不用接触代码 [英] Force java web start to use a proxy like Fiddler without touching code

问题描述

对于自动软件项目，我需要来自 Java Web Start 应用程序的一些请求和响应.

For a automatic software project i need some requests and responses from a Java Web Start application.

所以我安装了 Fiddler Web Debugger，然后我尝试使用这个 Fiddler 代理来嗅探所有请求.

So i installed Fiddler Web Debugger and then i tried to use this fiddler proxy to sniff all requests.

问题在于 Java Web Start 应用程序.

The problem is the Java Web Start application.

我将它添加到 .jnlp 文件中，并希望它有效...它没有！:(

I added this to the .jnlp file and hoped that it works... It doesnt! :(

  <property name="http.proxyHost" value="127.0.0.1"/>
  <property name="http.proxyPort" value="8888"/>

应用程序会忽略它.

然后我尝试设置 Java 设置.

Then i tried to set up the Java settings.

它也不起作用;(

Wireshark 无法解密 https/ssl 请求...

Wireshark cant decrypt the https/ssl requests...

我可以做什么来解密请求或读取请求，或者让使用 java web start 应用程序作为 fiddler 代理.

What could i do to decrypt the requests or to read the requests OR to let use the java web start application the fiddler proxy.

为什么java不能使用系统代理?>.>

Why java cant use the system proxy? >.>

推荐答案

有不同的方法:

1.)您可以在 java 系统设置中设置代理.打开系统设置\Java\Java 控制面板\网络设置.在那里您可以配置代理...

1.) You can set the proxy in the java system settings. Open System Settings \ Java \ Java Control Panel \ Networksettings. There you are able to configure the proxy...

2.)验证您的代理是否配置正确的另一种可能性是检查您的 Java 程序:

2.) Another possibility to verify if your proxy is configured correctly is to check within your java programm:

private Proxy findProxy(URI uri)
{
     try
     {
          ProxySelector selector = ProxySelector.getDefault();
          List<Proxy> proxyList = selector.select(uri);
          if (proxyList.size() > 1)
               return proxyList.get(0);
     }
     catch (IllegalArgumentException e)
     {
     }
     return Proxy.NO_PROXY;
}

3.)在您的程序中设置系统设置:

3.) Set the system settings within your programm:

System.getProperties().put( "proxySet", "true" );
System.getProperties().put( "proxyHost", "myProxyMachineName" );
System.getProperties().put( "proxyPort", "85" );

如果您还需要身份验证，请使用(更多详细信息这里)

If you need authentication also, use (more details here)

URLConnection connection = url.openConnection();
String password = "username:password";
String encodedPassword = base64Encode( password );
connection.setRequestProperty( "Proxy-Authorization", encodedPassword );
