使用Whistle代理抓取JVM HTTP请求

· One min read
info

注意把以下命令中对应路径替换成自己的:

  • D:\programs\jdk1.8.0_192: JDK 1.8 的安装目录
  • C:\Users\user\Downloads\rootCA.cer: 下载到本地的whistle代理根证书

生成证书​

方式一：生成keystore只有whistle根证书​

D:\programs\jdk1.8.0_192\jre\bin\keytool.exe -importcert -alias whistle -keystore "C:\Users\user\Downloads\whistle.p12" -file "C:\Users\user\Downloads\rootCA.cer" -storepass whistle -storetype PKCS12 -noprompt

方式二：在JDK默认根证书基础上追加whistle根证书​

D:\programs\jdk1.8.0_192\jre\bin\keytool.exe -importkeystore -srckeystore "D:\programs\jdk1.8.0_192\jre\lib\security\cacerts" -srcstoretype JKS -srcstorepass changeit -destkeystore "C:\Users\user\Downloads\whistle.p12" -deststoretype PKCS12 -deststorepass whistle

D:\programs\jdk1.8.0_192\jre\bin\keytool.exe -importcert -alias whistle -keystore "C:\Users\user\Downloads\whistle.p12" -file "C:\Users\user\Downloads\rootCA.cer" -storepass whistle -storetype PKCS12 -noprompt

使用​

要使用上述keystore，抓取HTTPS请求，需要设置以下 JVM 启动参数：

-DproxySet=true
-DproxyHost=127.0.0.1
-DproxyPort=8899
-Djavax.net.ssl.trustStore="C:\Users\user\Downloads\whistle.p12"
-Djavax.net.ssl.trustStorePassword=whistle
-Djavax.net.ssl.trustStoreType=PKCS12
-Djavax.net.debug=ssl,handshake

一般个人项目和公司项目要用不用的 user.name 和 user.email，一般情况下每次clone新项目，都要在项目根目录执行以下命令设置项目的邮箱账号信息：

git config --local user.name xxxx
git config --local user.email xxxx@yyy.com
