kotlin - 如何为 KTOR HTTPclient Multiplatform Kotlin 项目配置引擎？还需要添加 SSL 证书

Question

下面是我尝试过的代码。我正在 commonMain 块中尝试以下代码。

suspend fun callHttpFunction(){

val clientEngine = HttpClient{

        engine {
            pipelining = true
            threadsCount = 4
        }

    }

    clientEngine.post<String>("https","m2.testing.com",8080,
        "/TokenServiceEncrypt/api/base/TokenUpdated",requestBlock
    ) {
        headers.append("Content-Type", "application/json")
        headers.append("Accept", "application/json")
        headers.append("SessionToken", "seesfssfsf")
    }
    clientEngine.close()
}

//HttpClient(Apache) fails and so does HttpClient(OkHttp)

Answer 1

我设法使用返回 HttpClient 的期望/实际类每个平台都使用其专用的engine .

expect class HttpClientProvider() {
    fun getHttpClient(host: String, sslPin: String): HttpClient
}

actual class HttpClientProvider {
    actual fun getHttpClient(host: String, sslPin: String): HttpClient {
        val okHttpClient = OkHttpClient.Builder().apply {
            certificatePinner(
                CertificatePinner.Builder()
                    .add(host, sslPin)
                    .build()
            )
        }.build()

        return HttpClient(OkHttp) {
            engine {
                preconfigured = okHttpClient
            }
        }
    }
}

如您所见，您可以通过 OkHttpClient至 preconfigured在那里，您可以使用 OkHttp 的所有功能(我使用 certificatePinner() 、 socketFactory() 和 sslSocketFactory )。

这也适用于 iOS(还没有时间测试)。

private val client = HttpClientProvider().getHttpClient(stage.host, stage.sslPin).config {
    requestTimeout?.let {
        install(HttpTimeout) {
            requestTimeoutMillis = it.toLongMilliseconds()
        }
    }

    logLevel?.let {
        install(Logging) {
            logger = Logger.SIMPLE
            level = it
        }
    }
}

你可以使用正常的config { } - 块也是。
