How to capture HTTP(S) traffic from and to a Java web application with Fiddler2 or similar tool?
提问by Infeligo
I want to capture data that my web application sends and receives from a CAS server via HTTPS. I tried using Fiddler2, but couldn't make it capture traffic from Java web application. It seems I need to configure it to use Fiddler2 as a proxy. How do I do it correctly?
我想捕获我的 Web 应用程序通过 HTTPS 从 CAS 服务器发送和接收的数据。我尝试使用 Fiddler2，但无法使其捕获来自 Java Web 应用程序的流量。看来我需要将其配置为使用 Fiddler2 作为代理。我该怎么做才能正确？
Some additional info. I have already imported Fiddler's certificate with keytool. Running web application on Tomcat 7. Using IntelliJ Idea.
一些额外的信息。我已经用 keytool 导入了 Fiddler 的证书。在 Tomcat 7 上运行 Web 应用程序。使用 IntelliJ Idea。

Run the JVM with these parameters:
使用以下参数运行 JVM：
-Dhttps.proxyHost=yourhostwithfiddler -Dhttps.proxyPort=8888
Alternately, you could set the Java default proxy through a GUI - see http://www.java.com/en/download/help/proxy_setup.xml
或者，您可以通过 GUI 设置 Java 默认代理 - 请参阅http://www.java.com/en/download/help/proxy_setup.xml

In addition to Piskvor answer, make sure you configure Fiddler to capture the HTTPS traffic: Tools --> Fiddler Options --> HTTPS --> Capture HTTPS CONNECTs
除了 Piskvor 答案，请确保您配置 Fiddler 以捕获 HTTPS 流量：工具 --> Fiddler 选项 --> HTTPS --> 捕获 HTTPS CONNECTs

You can also use directly the settings screen: "File / Settings...", then choose"IDE Settings / HTTP Proxy". Then tick "Use proxy", "Host name": localhost, "Port number": 8888
您也可以直接使用设置屏幕：“文件/设置...”，然后选择“IDE 设置/HTTP 代理”。然后勾选“使用代理”，“主机名”：localhost，“端口号”：8888
