Ktor WebSocket 不支持 Android 土耳其语言环境？
Ktor WebSocket cannot support Android Turkish locale?
Ktor WebSocket 似乎不支持 Android 土耳其语言环境。
下面的代码在土耳其语言环境之外运行良好。当我将设备区域设置更改为土耳其语时崩溃（我检查了 28 个区域设置，包括阿拉伯语）
即使我在各种设备（SS smart phone，基于 AOSP8 的自定义设备）上对其进行了测试，但它也无法正常工作，只有不同的崩溃位置。
你能告诉我怎么做吗？
class MainActivity : AppCompatActivity() {
private fun startServer() {
embeddedServer(Netty, port = 8080) {
install(io.ktor.websocket.WebSockets) {
}
routing {
webSocket("/language") {
incoming.consumeEach { frame ->
when (frame) {
is Frame.Text -> println("######################### ${frame.readText()}")
}
}
}
}
}.start()
}
private val client = HttpClient(CIO) {
install(io.ktor.client.features.websocket.WebSockets)
}
private fun connectLocalhost() {
CoroutineScope(Dispatchers.IO).launch {
try {
client.ws(host = "localhost", port = 8080, path = "/language") {
send(Frame.Text("My name is Hello World"))
incoming.consumeEach { frame ->
when (frame) {
is Frame.Text -> println(frame.readText())
}
}
}
} catch (e:Throwable) {
println(e.message)
println("------------------------- ${e.message}")
}
}
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
startServer()
connectLocalhost()
}
}
Ktor 被这样使用
ext.kotlin_version = "1.3.72"
ext.ktor_version = '1.2.5'

通过升级ktor版本到1.3.2以上解决
Ktor WebSocket 似乎不支持 Android 土耳其语言环境。 下面的代码在土耳其语言环境之外运行良好。当我将设备区域设置更改为土耳其语时崩溃（我检查了 28 个区域设置，包括阿拉伯语） 即使我在各种设备（SS smart phone，基于 AOSP8 的自定义设备）上对其进行了测试，但它也无法正常工作，只有不同的崩溃位置。
你能告诉我怎么做吗？
class MainActivity : AppCompatActivity() {
private fun startServer() {
embeddedServer(Netty, port = 8080) {
install(io.ktor.websocket.WebSockets) {
}
routing {
webSocket("/language") {
incoming.consumeEach { frame ->
when (frame) {
is Frame.Text -> println("######################### ${frame.readText()}")
}
}
}
}
}.start()
}
private val client = HttpClient(CIO) {
install(io.ktor.client.features.websocket.WebSockets)
}
private fun connectLocalhost() {
CoroutineScope(Dispatchers.IO).launch {
try {
client.ws(host = "localhost", port = 8080, path = "/language") {
send(Frame.Text("My name is Hello World"))
incoming.consumeEach { frame ->
when (frame) {
is Frame.Text -> println(frame.readText())
}
}
}
} catch (e:Throwable) {
println(e.message)
println("------------------------- ${e.message}")
}
}
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
startServer()
connectLocalhost()
}
}
Ktor 被这样使用

ext.ktor_version = '1.2.5'
