How can i pass properties to the conf file?

Is there a shorthand to get the contents of an http POST operation in a map? I use the same procedure as the example linked from http://ktor.io/samples/post.html, but find it unneccessary to iterate over a MultipartData structure to get my values. Changing the content type from form-data to x-www-form-urlencoded doesn't help, I still don't find a simple

toMap()

. Am I missing something?

Is there any way to react to a client closing a connection? My use case is doing some heavy calculations on request and then sending a small result. I would like to immediately stop the calculations when the client closes the connection.

There is a proposal to change the default log level for

CallLogging

Ktor feature to

INFO

and use

INFO

as a default log threshold in all the sample log configuration files. So, by default,

INFO

,

WARN

, and

ERROR

will get printed. The idea that you should see all the requests in your logs and if you want to get more detailed logs (

DEBUG

or

TRACE

) from certain subsystems/parts of your Ktor app, then you can go and turn on finer-grained logging level for those subsystems. What do you think? What is you experience with logging level?

any benefits to use Application.main() over embeddedServer() or vice versa?

I've trouble finding a way to end processing. I'm using a

post()

handler, go through all the multiparts and if I find a

FileItem

, I store it, send a redirect and want to be done. Of course, if there's none, I want to redirect back to the main site. But my code always runs into the second redirect (in addition to the first one).

is this deprecated now with ktor

0.9.1

?

fun main(args: Array<String>) {
    val server = embeddedServer(Netty, commandLineEnvironment(args))
    server.start()
}

Does

call.receive<SomeDataClass>()

parse json string?

Hi, can ktor-client use socks5 proxies or it depends on jetty/apache etc?

What is best approach to handle exception for various accept content types? For example, if client asks

application/json

, I would like serialize exception using gson. If client asks

text/html

, then simple html page and for

text/plain

print only message.

is there a recommended way to intercept the response across all routes? i'd like to audit the response information, and have access to an injected service. (basically i want to use an audit service i've defined and log the response information).

I was just setting up a new project with

ktor-auth-jwt

as a dependecy and I now wonder why I have a transitive dependency for

ktor-server-test-host

. I searched among the dependency tree and found that

ktor-auth

declares it. Excluding it within my build file would be an option but is there any need for this to be not declared as

testCompile

?

Hey folks! What kind of analytics service you would recommend to use with ktor?

Sometimes I'm getting this:

[nettyWorkerPool-3-1] WARN  i.n.channel.DefaultChannelPipeline - An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.
java.nio.channels.ClosedChannelException: null
	at io.netty.channel.AbstractChannel$AbstractUnsafe.write(...)(Unknown Source)

Which is the correct way to set an exception handler to Netty while using ktor?

I guess I should just use

newSingleThreadContext()

instead? https://github.com/Kotlin/kotlinx.coroutines/blob/master/coroutines-guide.md#dispatchers-and-threads

It would be great if I could pass in an existing

GsonBuilder

and not only configure it in the

gson

block:

install(ContentNegotiation) (
  gson {
    setDateFormat(DateFormat.LONG)
  }
}

like this:

install(ContentNegotiation) (
  gson(existingGsonBuilder)
}

I am new with ktor , Below is the nodejs code to return response with status code and json string (working fine and response is getting captured at client side)

res.status(200).json({"message":"foo","something":"something"})

I am trying to reproduce the same functionality with ktor and below is what i tried and it is not getting captured at client side, can someone please help me to wright it in ktor (in single line if possible )

call.response.status(HttpStatusCode.OK)
val item = ResponseJson("foo"  , "something")
call.respond(item)

no main manifest attribute, in /my_app.jar

was the error

Seems ktor's

StatusPages

do not implement the 418 status code ... Outrageous!

If I have a routing setup and I cant figure out why something doesnt match.. what is the easiest way to debug it ?

Ok so I need

resource("/{...}", "static/index.html")

. My problem was that I was trying to use

resource("*", "static/index.html")

or

resource("/*", "static/index.html")

, but it doesn't work as

/*

matches

/a

but not

/a/b

. Something like

/**

would make much more sense than

/{...}

imho

Anyone know how I can expose members to routes / application?

How do you configure timeouts on the ktor http client?

Hi, is there an opinionated way to implement health checks ?

I have a vue-js app that is bundled together with webpack yes, I keep that in a separate folder and serve that folder as a static asset. What happens when CORS is not enabled at all? When it is not I can use relative paths but I cannot let another host call the server from javascript (which makes sense, that is how it should be) but when I enable CORS to give access to my javascript host, why is the self hosted javascript site then denied access? Do you have something I can look at concerning the webpack issue?

is ping/pong in websocket handled automatically in ktor?

I have a problem with paths. I want to make a redirect from

/path

to ‘/path/’ because the HTML returned by ‘/path/’ has some relative paths for images, css, … But when I declare theses 2 paths in

routing

, ktor seems to make no difference between them.
