处理https网络服务器的非SSL客户端机器人程序

我正在使用KTor https服务器为我的Android应用程序，我注意到机器人试图连接到我的服务器失败，因为TLS握手没有发生。这是恼人的，因为我的日志文件充满了这些巨大的转储由netty为WARN标记与SL 4J日志。有没有办法处理这样的客户端，而不会导致错误/警告？我尝试在Ktor中使用请求验证插件，但它不起作用。这是我的logback.xml：

<configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{dd-MM-YYYY HH:mm:ss.SSS} [%thread] [%-5level] %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>
    <root level="trace">
        <appender-ref ref="STDOUT"/>
    </root>
    <logger name="org.eclipse.jetty" level="WARN"/>
    <logger name="io.netty" level="WARN"/>
    <logger name="io.ktor" level="WARN"/>
</configuration>

字符串
这是我在/plugins文件夹中Validation.kt中的请求验证函数：

fun Application.configureValidation() {

    println("Inside application validation")//this is printed at app startup
    install(RequestValidation) {
        validate<String> {bodyText ->
            if (bodyText.contains("mySite")) {
                println("Received request validation text: $bodyText")//this is never printed
                ValidationResult.Valid
            }
            else if (bodyText.contains("myApp")) {
                println("Received request validation text: $bodyText")//this is never printed
                ValidationResult.Valid
            }
            else {
                println("Received request validation text: $bodyText")//this is never printed
                ValidationResult.Invalid("Request Validation failed for bot")
            }

        }

        validate {
            filter { body ->
                body is Any
            }
            validation { body ->
                println("Received request validation 2 text: $body")//this is never printed
                if(body.toString().isNullOrEmpty())
                    ValidationResult.Invalid("Request Validation failed because its empty")
                else
                    ValidationResult.Valid
            }
        }
    }
    println("After application validation")//this is printed at app startup
}

型
日志文件中不会打印任何接收到的请求验证println。
在我的Application.kt中：

fun Application.module() {

    printMyStr("Inside Application")

    configureValidation()
    printMyStr("After validation")

    install(StatusPages) {
        exception<RequestValidationException> { call, cause ->
            call.respond(HttpStatusCode.BadRequest, cause.reasons.joinToString())
        }
    }

    install(ContentNegotiation) {
        json()
    }

    printMyStr("Before socket")

    configureSockets()
    printMyStr("Before routing")

    configureRouting()
    printMyStr("After routing")
}

使用Janino过滤异常是不起作用的，正如Aleksei在上面的评论中所推荐的那样。下面是我的logback.xml：

<configuration>
    <evaluator name="NotSslRecordExceptionSuppressor">
        <expression>throwable != null &amp;&amp; throwable instanceof io.netty.handler.ssl.NotSslRecordException</expression>
    </evaluator>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{dd-MM-YYYY HH:mm:ss.SSS} [%thread] [%-5level] %logger{36} - %msg %ex{full,InvalidLoginExceptionSuppressor}%n</pattern>
            <immediateFlush>false</immediateFlush>
        </encoder>
    </appender>
    <root level="trace">
        <appender-ref ref="STDOUT"/>
    </root>
    <logger name="org.eclipse.jetty" level="WARN"/>
    <logger name="io.netty" level="WARN"/>
    <logger name="io.ktor" level="WARN"/>
</configuration>

由于这没有工作，并打印follwing仍然：

24-11-2023 16:22:09.749 [eventLoopGroupProxy-3-1] [WARN ] i.n.h.s.ApplicationProtocolNegotiationHandler - [id: 0x25f5cf98, L:0.0.0.0/0.0.0.0:1234 !

所以唯一的解决办法似乎是将logger更改为只打印ERROR级别的消息，而不是logback.xml中的WARN级别：

<configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{dd-MM-YYYY HH:mm:ss.SSS} [%thread] [%-5level] %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>
    <root level="trace">
        <appender-ref ref="STDOUT"/>
    </root>
    <logger name="org.eclipse.jetty" level="WARN"/>
    <logger name="io.netty" level="ERROR"/>
    <logger name="io.ktor" level="WARN"/>
</configuration>
