java - Fiddler java https - "unable to find valid certification path to requested target"

Question

我关注了instructions在 Fiddler 中为 java 客户端程序设置 https 流量解密。但我在 IntelliJ 中仍然遇到此错误

我还尝试在程序本身中设置属性(而不是使用虚拟机选项)

System.setProperty("http.proxyHost", "127.0.0.1");
System.setProperty("https.proxyHost", "127.0.0.1");
System.setProperty("http.proxyPort", "8888");
System.setProperty("https.proxyPort", "8888");
System.setProperty("javax.net.ssl.trustStore", "c:\\Users\\tcb\\IdeaProjects\\FiddlerKeystore");
System.setProperty("javax.net.ssl.trustStorePassword", "SomePassword");

还是同样的错误。最后，我尝试将 FiddlerRoot.cer 导入 jre 的 cacerts 存储

C:\windows\system32>"c:\Program Files\Java\jdk1.7.0_80\bin\keytool.exe" -import -trustcacerts -alias Fiddler -file c:\users\tcb\Desktop\FiddlerRoot.cer -keystore "c:\Program Files\Java\jre7\lib\security\cacerts"

但我仍然收到“无法找到请求目标的有效证书路径”错误。

什么可能导致此错误？

Answer 1

您使用的是哪个证书生成器:makecert 或 certenroll？ (参见http://textslashplain.com/2015/10/30/reset-fiddlers-https-certificates/)

我问的原因是 makecert 生成的证书不包含 AKI 扩展，如果没有它们，Java 可能无法正确构建证书链。当证书由 certenroll 或 bouncycaSTLe certmaker 插件 生成时，此问题得到解决，它们都将 AKI 扩展添加到生成的证书中。
