How to add HostnameVerifier to ktor client using okhttp engine - kotlin

Im trying to add the HostnameVerifier
HostnameVerifier { _, _ -> true }
to my kotlin multiplatform ktor client and I couldn't be able to understand how to do that:
#KtorExperimentalAPI actual val httpClient = HttpClient(OkHttp) {
engine {
// how to set HostnameVerifier?
val loggingInterceptor = HttpLoggingInterceptor()
loggingInterceptor.level = HttpLoggingInterceptor.Level.BODY
addInterceptor(loggingInterceptor)
}
}

Something like that:
actual val httpClient = HttpClient(OkHttp) {
engine {
// https://square.github.io/okhttp/3.x/okhttp/okhttp3/OkHttpClient.Builder.html
config { // this: OkHttpClient.Builder ->
// ...
hostnameVerifier {
_, _ -> true
}
}
val loggingInterceptor = HttpLoggingInterceptor()
loggingInterceptor.level = HttpLoggingInterceptor.Level.BODY
addInterceptor(loggingInterceptor)
}
}

Kotlin Ktor client 403 forbidden cloudflare

So im trying to request a side with proxies that is protected with cloudflare. The problem is i get 403 forbidden cloduflare error but only when im using proxies without it works. But the proxies are not the problem i tried them with python(requests module) and in my browser there i dont get blocked. My code
suspend fun scrape() {
val client = HttpClient {
followRedirects = true
install(ContentNegotiation) {
json(Json {
ignoreUnknownKeys = true
})
}
engine {
proxy =
ProxyBuilder.http("http://ProxyIP:proxyPort")
}
defaultRequest {
val credentials = Base64.getEncoder().encodeToString("ProxyUser:ProxyPassword".toByteArray())
header(HttpHeaders.ProxyAuthorization, "Basic $credentials")
}
}
val response = client.get("http://example.com")
val body = response.bodyAsText()
println(body)
println(response.status.hashCode())
Fixxed it
suspend fun scrape() {
val client = HttpClient(Apache) {
install(ContentNegotiation) {
json(Json {
ignoreUnknownKeys = true
})
}
engine {
followRedirects = false
customizeClient {
setProxy(HttpHost("hostname", port))
val credentialsProvider = BasicCredentialsProvider()
credentialsProvider .setCredentials(
AuthScope("hostname", port),
UsernamePasswordCredentials("username", "password")
)
setDefaultCredentialsProvider(credentialsProvider )
}
}
}
val response =
client.get("http://example.com") {
}
val body = response.bodyAsText()
println(body)
println(response.status.hashCode())
}
There is a problem with making a request through a proxy server using the CIO engine. I've created an issue to address this problem. As a workaround, please use the OkHttp engine instead of CIO.
Here is how you can use a proxy with the Basic authentication:
import io.ktor.client.*
import io.ktor.client.engine.okhttp.*
import io.ktor.client.request.*
import kotlinx.coroutines.runBlocking
import okhttp3.Authenticator
import okhttp3.Credentials
import okhttp3.OkHttpClient
import java.net.Proxy
fun main(): Unit = runBlocking {
val proxyAuthenticator = Authenticator { _, response ->
response.request.newBuilder()
.header("Proxy-Authorization", Credentials.basic("<username>", "<password>"))
.build()
}
val client = HttpClient(OkHttp) {
engine {
preconfigured = OkHttpClient.Builder()
.proxy(Proxy(Proxy.Type.HTTP, java.net.InetSocketAddress("127.0.0.1", 3128)))
.proxyAuthenticator(proxyAuthenticator)
.build()
}
}
val response = client.get("http://eu.kith.com/products.json")
println(response.status)
}

Chain validation failed

I'm having the below Okhttp code:
val client = OkHttpClient()
val mediaType = MediaType.parse("application/x-www-form-urlencoded")
val body = RequestBody.create(mediaType, "tenant_id=xxxx&client_id=xxxx&client_secret=xxxx&resource=xxxx&grant_type=client_credentials")
val request = Request.Builder()
.url("https://sxxx.com/axxx/oauth2/token")
.post(body)
.addHeader("Content-Type", "application/x-www-form-urlencoded")
.build()
val response = client.newCall(request).execute()
And want to convert it usint ktor, so I wrote the below:
class Greeting {
private val httpClient = HttpClient {
}
#Throws(Exception::class)
suspend fun greeting(): String {
val response = httpClient.request {
method = HttpMethod.Post
url {
protocol = URLProtocol.HTTPS
host = "sxxx.com"
path("axxx/oauth2/token")
// encodedParameters
trailingQuery = true
parameters.append("tenant_id", "xxxx")
parameters.append("client_id", "xxxx")
parameters.append("client_secret", "xxxx")
parameters.append("resource", "xxxx")
parameters.append("grant_type", "client_credentials")
}
headers {
append(HttpHeaders.ContentType, "application/x-www-form-urlencoded")
}
}
return response.bodyAsText()
}
}
And calling my new code as:
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
MyApplicationTheme {
Surface(
modifier = Modifier.fillMaxSize(),
color = MaterialTheme.colors.background
) {
val scope = rememberCoroutineScope()
var text by remember {
mutableStateOf("Loading")
}
LaunchedEffect(true){
scope.launch {
text = try {
Greeting().greeting()
} catch (e: Exception) {
e.localizedMessage ?: "error"
}
}
}
Greeting(text)
}
}
}
}
}
#Composable
fun Greeting(text: String) {
Text(text = text)
}
But instead of getting the required token, I'm getting the response: Chain validation failed
Make sure that:
Your server certificate is valid.
Your android system datetime is correct.

Okhttp interceptor not working showing 401(Unauthenticated) response

OKHTTP Interceptor not working It gives me 401 Response(Unauthenticated/UnAuthorized)
Here is my Interceptor Class
InterceptorClass
class NetworkInterceptor(context: Context) : Interceptor {
private val applicationContext = context.applicationContext
private val sharedPreferenceData = SharedPreferenceData(applicationContext)
override fun intercept(chain: Interceptor.Chain): Response {
if (!isConnectionAvailable()) {
throw NoConnectionException("Error! Connecting to the network")
} else {
val requestBuilder = chain.request().newBuilder()
val token = sharedPreferenceData.getString("token", "")
requestBuilder.addHeader("Authorization", "Bearer $token")
Log.e("Token", "intercept: $token")
return chain.proceed(requestBuilder.build())
}
}
#Suppress("DEPRECATION")
fun isConnectionAvailable(): Boolean {
val cm =
applicationContext.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
cm.activeNetworkInfo.also {
return it != null && it.isConnected
}
}
}
Here is the network instance class
object NetworkInstance {
fun getApi(context: Context): DataApi {
val gsonBuilder = GsonBuilder()
gsonBuilder.setLenient()
val gson = gsonBuilder.create()
val logging = HttpLoggingInterceptor()
logging.setLevel(HttpLoggingInterceptor.Level.BODY)
val client = OkHttpClient
.Builder()
.addInterceptor(logging)
.addInterceptor(NetworkInterceptor(context))
.readTimeout(60, TimeUnit.SECONDS)
.writeTimeout(60, TimeUnit.SECONDS)
.addInterceptor(logging)
.build()
val retrofit = Retrofit
.Builder()
.client(client)
.baseUrl(BuildConfig.BASE_URL)
.addConverterFactory(GsonConverterFactory.create(gson))
.build()
return retrofit.create(DataApi::class.java)
}
}
The issue was because of my Stupidity. I have added BASE_URL inside build.gradle which generates a Static Final variable inside BuildCondig.java which can't be altered. While Adding header BASE_URL can't be changed.

Testing Soap Consumer. 'uri' must not be empty

I have a method for calling the "marshalSendAndReceive" method on sending a message over Soap.
class SoapConnector : WebServiceGatewaySupport() {
fun getClient(documentId: String): Person {
val request = getSearchRequest(documentId)
val response = webServiceTemplate.marshalSendAndReceive(request) as SearchResponse
return getPerson(response)
}
I also have a configuration file.
#Configuration
class SearchClientConfig {
#Bean
fun marshaller(): Jaxb2Marshaller? {
return Jaxb2Marshaller().apply {
contextPath = "wsdl" //here path to generated java classes from wsdl
}
}
#Bean
fun searchCilent(marshallerJaxb: Jaxb2Marshaller): SoapConnector {
return SoapConnector().apply {
defaultUri = "http://20.40.59.1:8080/cdi/soap/services/ServiceWS"
marshaller = marshallerJaxb
unmarshaller = marshallerJaxb
}
}
}
I want to Mock this method.
#RunWith(SpringRunner::class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
#Sql(scripts = ["classpath:db/init.sql"])
#AutoConfigureEmbeddedDatabase(
beanName = "dataSource",
provider = AutoConfigureEmbeddedDatabase.DatabaseProvider.DOCKER
)
class SoapTest : WebServiceGatewaySupport(){
private lateinit var webServiceGatewaySupport: WebServiceGatewaySupport
private lateinit var connector: SoapConnector
#BeforeEach
fun setUp() {
webServiceGatewaySupport = Mockito.mock(WebServiceGatewaySupport::class.java)
}
#Test
fun getClientTest() {
Mockito.`when`(webServiceTemplate.marshalSendAndReceive(ArgumentMatchers.anyObject())).thenReturn(SearchResponse())
connector.getClient(RandomStringUtils.randomAlphabetic(7))
}
}
But there is a bug:
java.lang.IllegalArgumentException: 'uri' must not be empty
I don't understand what the problem is and I don't know how to make a working Mock of this method.

Ktor HttpClient Mock Fails

I'm trying to create a Ktor (1.3.1) HttpClient Mock with JsonFeature like this:
#Test
fun mockFailure() = runBlocking {
val mock = MockEngine { call ->
respond("{}",
HttpStatusCode.OK,
headersOf("Content-Type", ContentType.Application.Json.toString()))
}
val client = HttpClient(mock) {
install(JsonFeature) {
serializer = KotlinxSerializer()
}
}
val resp = client.get<JsonObject>("dsf")
}
It appears to process it correctly, but then I get this error:
io.ktor.client.call.NoTransformationFoundException: No transformation found: class kotlinx.coroutines.io.ByteBufferChannel -> class kotlinx.serialization.json.JsonObject
with response from http://localhost/dsf:
status: 200 OK
response headers:
Content-Type: application/json
at io.ktor.client.call.HttpClientCall.receive(HttpClientCall.kt:79)
Try installing client content negotiation plugin in the HttpClient block:
val client = HttpClient(mock) {
install(JsonFeature) {
serializer = KotlinxSerializer()
}
//Here
install(ContentNegotiation) {
json(Json {
prettyPrint = true
isLenient = true
})
}
}
Required dependencies implementation("io.ktor:ktor-client-content-negotiation:$ktor_version")
Json Serialization implementation("io.ktor:ktor-serialization-kotlinx-json:$ktor_version")
Also change the last line to val resp = client.get<JsonObject>("dsf").body()
