android - Kotlin - 检查 URL 是否可访问时出现“I/System.out: (HTTPLog)-Static: isSBSettingEnabled false”错误

Question

我有一个通过 VPN 连接到网络应用程序的小型 Android 应用程序。

该应用程序显示一个向导，用于输入和保存 Web 应用程序的所有凭据（域、端口、http/s、用户和密码）。当用户保存时，我检查是否可以访问 URL 并显示警告或移动到包含 WebView 的下一个活动。

这是用户点击保存时发生的情况：

fun triggerSaveSettingsAction()
{
    Log.i("MyApp","ServerWizardActivity > triggerSaveSettingsAction")

    if(checkInputData() == false)
    {
        displayDialogBox("WARNING", message = "Please fill in all the fields in order to continue!")
    }
    else
    {
        val serverAddress: String = tvServerAddress?.text?.replace("\\s".toRegex(), "").toString()
        val serverPort: String = tvServerPort?.text?.replace("\\s".toRegex(), "").toString()
        val serverUser: String = tvServerUser?.text?.replace("\\s".toRegex(), "").toString()
        val serverPassword: String = tvServerPassword?.text?.replace("\\s".toRegex(), "").toString()
        val isSecureServer: String = (cbSecureServer?.isChecked == true).toString()

        setProgressBarVisible()

        checkURLResponse(serverAddress, serverPort, isSecureServer)

        Timer("SettingUp", false).schedule(3000) // Nasty workaround to prevent setProgressBarInvisible to early
        {
            if(isReachable!!)
            {
                sharedPref!!.saveDataToSharedPreferences("serverAddress", serverAddress)
                sharedPref!!.saveDataToSharedPreferences("serverPort", serverPort)
                sharedPref!!.saveDataToSharedPreferences("serverUser", serverUser)
                sharedPref!!.saveDataToSharedPreferences("serverPassword", serverPassword)
                sharedPref!!.saveDataToSharedPreferences("isSecureServer", isSecureServer)

                runOnUiThread{
                    setProgressBarInvisible()
                    displayDialogBox("NOTIFICATION", "The new settings will become availiable the next time you start the application!")
                }
            }
            else
            {
                runOnUiThread{
                    setProgressBarInvisible()
                    displayDialogBox("WARNING", "The server address or port are not valid or there is a problem with your Internet connection!")
                }
            }
        }
    }
}

这是checkURLResponse(serverAddress, serverPort, isSecureServer)：

fun checkURLResponse(serverAddress: String, serverPort: String, isSecureServer: String)
{
    Log.i("MyApp","ServerWizardActivity > checkURLResponse")

    var fullURL: String? = null
    val partialURL: String? = "/main.html"

    if(isSecureServer.toBoolean()) { fullURL = "https://$serverAddress:$serverPort${partialURL}" }
    else { fullURL = "http://$serverAddress:$serverPort${partialURL}" }

    Thread{
        Log.i("MyApp","ServerWizardActivity > Thread")

        try
        {
            val url = URL(getPartialURL())
            val urlc = url.openConnection() as HttpURLConnection
            urlc.connectTimeout = 3 * 1000
            urlc.connect()

            if ((urlc.responseCode >= 200) && (urlc.responseCode <= 299))
            {
                Log.i("Connection", "Try > Success!")
                isReachable = true
            }
            else
            {
                Log.i("Connection", "Try > Failed!")
            }
        }
        catch (e: Exception)
        {
            Log.i("Connection", "Catch > Failed!")
        }
    }.start()
}

撇开讨厌的解决方法不谈，这适用于不需要 VPN 连接的其他域。

在这种情况下，我得到这个：

I/System.out: (HTTPLog)-Static: isSBSettingEnabled false
I/System.out: (HTTPLog)-Static: isSBSettingEnabled false

iOS 版本使用相同的凭据和 VPN 可以正常工作。此外，该 URL 可在任何浏览器中访问。

不确定这是手机相关问题还是连接问题，因为我只有一部手机要测试（三星 Galaxy S7 和 Android 8.0）。

我发现一些线程声称这是三星独有的问题，但我无法验证。此外，对我来说，它看起来更像是一个证书问题。但这并不能解释为什么它可以在浏览器和 iOS 应用程序中运行。

有任何想法吗？

乐：

毕竟这似乎是一个证书错误 - SEC_ERROR_UNKNOWN_ISSUER。我设法绕过它使用handler.proceed()：

override fun onPageStarted(view: WebView?, url: String, favicon: Bitmap?)
{
    Log.i("MyApp","MainActivity > onPageStarted")

    super.onPageStarted(view, url, favicon)

    val currentURL: String? = wvMainView!!.url
    Log.i("MyApp","MainActivity > onPageStarted > ${currentURL}")

    view?.setWebViewClient(object : WebViewClient()
    {
        override fun onReceivedSslError(view: WebView, handler: SslErrorHandler, error: SslError)
        {
            Log.i("MyApp","MainActivity > shouldOverrideUrlLoading > ${error}")
            Log.i("MyApp","MainActivity > onReceivedSslError > currentURL > ${currentURL!!}")

            handler.proceed()
        }
    })
}

问题是，onPageStarted我onPageFinished正在根据当前 URL 执行一些操作。基本上，我有很多这样的如果：if(currentURL!!.contains("main.html")).

不幸的是，现在看来 currentURL 总是返回相同的 URL，即初始 URL。无论我在 Web 应用程序中做什么，它都会返回初始 URL。

此外，如果我尝试将它与没有证书错误的 Web 应用程序一起使用，它会无法加载。
