带有自签名证书的 ktor 客户端 https 请求

Question

我有一个 Ktor 服务器应用程序（其余 api）运行一个自签名证书。

它在浏览器中工作正常（在警告和确认之后）端口 80 被重定向到 8443。

但如果我从 Ktor Apache 客户端尝试此操作：

fun main(args: Array<String>) = runBlocking {

    val client = HttpClient(Apache) {
        install(JsonFeature) {
            serializer = GsonSerializer()
        }
    }

    val job = GlobalScope.launch {
        try {
            //self-signed certificate
            val resultWillFail = client.get<String>("https://10.0.0.11:8443/get-my-services")
            println("${resultWillFail}")
            val resultOk = client.get<String>("https://en.wikipedia.org/wiki/Main_Page") //ok
            println("${resultOk}")
        } catch (e: Exception) {
            println("Error: ${e.message}")
        }
    }

    job.join()
}

我对 https://10.0.0.11:8443/get-my-services 的请求将失败：

Error: General SSLEngine problem

我也尝试过使用 curl 进行同样的操作：

curl: (77) schannel: next InitializeSecurityContext failed: SEC_E_UNTRUSTED_ROOT (0x80090325) - The certificate chain was issued by an authority that is not trusted.

所以我的问题是：如何在 ktor 客户端 (Apache) 中使用自签名证书？

谢谢， J

您需要将 Apache HttpClient 配置为忽略自签名证书，并将其传递给 KTor。根据信息here，您可以使用以下代码忽略自签名证书验证：

// use the TrustSelfSignedStrategy to allow Self Signed Certificates
val sslContext = SSLContextBuilder
        .create()
        .loadTrustMaterial(TrustSelfSignedStrategy())
        .build()

val allowAllHosts = NoopHostnameVerifier()
val connectionFactory = SSLConnectionSocketFactory(sslContext, allowAllHosts)

val client = HttpClients
        .custom()
        .setSSLSocketFactory(connectionFactory)
        .build()

您要做的最后一件事是在您的 KTor 代码中使用客户端。我自己还没试过，但让我看看你怎么样。

根据 Erik 的回答，这就是我让 Ktor Apache Client 接受自签名证书的方式：

fun main(args: Array<String>) = runBlocking {
    val client = HttpClient(Apache) {
        install(JsonFeature) {
            serializer = GsonSerializer()
        }
        engine {
            customizeClient {
                setSSLContext(
                    SSLContextBuilder
                        .create()
                        .loadTrustMaterial(TrustSelfSignedStrategy())
                        .build()
                )
                setSSLHostnameVerifier(NoopHostnameVerifier())
            }
        }
    }

    val job = GlobalScope.launch {
        try {
            val sslGetResult = client.get<String>("https://10.0.0.11:8443/get-my-services")
            println("${sslGetResult}")
        } catch (e: Exception) {
            println("Error: ${e.message}")
        }
    }

    job.join()
}
