Description
I'm using ktor 1.3.2 with CIO engine, when I try to send a get request to URL https://1.0.0.1/dns-query?ct=application/dns-json&cd=false&do=false&type=A&name=google.com by the following code:
suspend fun requestJson(hostname: String): DnsResponse {
HttpClient(CIO) {
install(JsonFeature) {
serializer = KotlinxSerializer()
}
install(HttpTimeout)
}.use {
return withContext(Dispatchers.IO) {
it.get<DnsResponse>("https://1.0.0.1/dns-query?ct=application/dns-json&cd=false&do=false&type=A&name=google.com") {
timeout {
requestTimeoutMillis = 5000
}
}
}
}
}an error occurred with the message Exception in thread "main" io.ktor.client.features.ClientRequestException: Client request(https://1.0.0.1/dns-query?ct=application%2Fdns-json&cd=false&do=false&type=A&name=google.com) invalid: 403 Forbidden, but when I try to access this URL by using a browser or postman or even using the old-school URLConnection in java, it works fine and returns the correct response, for example, the code
val url = URL("https://1.0.0.1/dns-query?ct=application/dns-json&cd=false&do=false&type=A&name=google.com")
val conn = url.openConnection() as HttpURLConnection
conn.connect()
val bf = BufferedReader(InputStreamReader(conn.inputStream))
var line: String = ""
while (bf.readLine().let { if (it == null) false else {line += it; true} }) {
}
println(line)will print
{"Status":0,"TC":false,"RD":true,"RA":true,"AD":false,"CD":true,"Question":[{"name":"google.com","type":1}],"Answer":[{"name":"google.com","type":1,"TTL":59,"data":"172.217.5.78"}]}and everything looks fine
