如何使用Gatling和SSL双向禁用SSL主机名验证

Question

我正在尝试使用SSL双向创建Gatling测试，但我无法禁用主机名验证。我正在使用加特林2.3。这是我的加特林配置：

ssl {
  keyStore {
    type = "JKS"
    file = "keystore.jks"
    password = "changeit"
    #algorithm = ""
  }
  trustStore {
    type = "JKS"
    file = "truststore.jks"
    password = "changeit"
    #algorithm = ""
  }
}
ahc {
  acceptAnyCertificate = true
  ....
}

我还在我的应用程序开头添加了这个系统属性

System.setProperty("jdk.tls.allowUnsafeServerCertChange", "true")
System.setProperty("sun.security.ssl.allowUnsafeRenegotiation", "true")

我可以看到我的密钥库和trutstore正确使用但我一直有这个问题：

java.security.cert.CertificateException: No subject alternative DNS name matching <my_dns> found.

Answer 1

从Gatling SSL documentation你可以尝试禁用SNI（-Djsse.enableSNIExtension=false）。但是，如果你真的需要SNI（SSL虚拟主机），你不想这样做，你需要编写自己的HostNameVerifier代码，虽然我不知道如何在Gatling中包含它。

Answer 2

如果有人仍在寻找解决方案：此功能已在Gatling的v3.0中实现。

相关配置参数为：

ahc {
    enableSni = true                                    # When set to true, enable Server Name indication (SNI)
    enableHostnameVerification = false                  # When set to true, enable hostname verification: SSLEngine.setHttpsEndpointIdentificationAlgorithm("HTTPS")
}
