I have a similar problem to this person and I am unsure why.
my post action is called from a form submission and the controller code
def processFreeDoc = UserAwareAction {
implicit request => {
userEmailForm.bindFromRequest.fold(
formWithErrors => {
Logger.error("Error processing the form %s "format formWithErrors.errors)
Redirect(routes.Application.index)
},
data => {
val sessionProduct = getSessionUnProcessedProduct(data.sessionId, data.documentName)
if(sessionProduct != null){
Logger.info("Found")
sessionProduct.updateProcessing(data.emailAddress, data.sessionId)
Redirect(routes.Application.index)
}
else
Logger.info("Nothing found")
Redirect(routes.Application.checkoutFree(data.sessionId))
}
)
}
}
is skipped entirely. There are no errors in the IDE(IDEA) console and the breakpoint at the entry of the method is not reached so none of the log messages are seen.
EDIT :
The relevant route in the routes file - POST /processFreeDoc controllers.Application.processFreeDoc

I have the following backend. If going to the "localhost:8080", the login page is loaded by redirecting from "/" to "login". Login page is loaded. At submitting the login form, the "perform-login" is called. However, for some reason, there is no redirect to "storage" page. Why?
P.S. If requesting the page "storage" manually, it is loaded. The problem is with the redirect from "login" page to "storage" page. Probably, it has something to do with setting the cookies, as this command also has the return type Route.
Scala version: 2.13.6,
Akka HTTP version: 10.2.6
object Backend {
def main(args: Array[String]) = {
implicit val system = ActorSystem(Behaviors.empty, "lowlevel")
// needed for the future map/flatmap in the end
implicit val executionContext: ExecutionContext = system.executionContext
val topLevelRoute: Route =
concat(
pathSingleSlash {
redirect("login", StatusCodes.PermanentRedirect)
},
path("login") {
complete("my login page")
},
path("storage") {
cookie("token") { tokenCookie =>
println("you managed to login, token:" + tokenCookie.value + "ENDLINE")
complete("my storage page")
}
},
path("perform-login") {
formFields("Username", "Password") { (username, password) =>
var isAbleToLogin = database.isUserLoggedIn(username, password)
if (isAbleToLogin == true) {
setCookie(HttpCookie("token", value="ThisIsMyStrongAccessToken")) {
//TODO: debug why does not redirect to main page
redirect("storage", StatusCodes.PermanentRedirect)
}
}
else {
reject(ValidationRejection("bad credentials"))
}
}
},
path(Remaining) { pathRest =>
reject(ValidationRejection("topLevelRoute, unknown path:" + pathRest + "ENDLINE"))
}
)
val binding = Http().newServerAt("localhost", 8080).bind(topLevelRoute)
println(s"Server online at http://localhost:8080/\nPress RETURN to stop...")
StdIn.readLine() // let it run until user presses return
binding
.flatMap(_.unbind()) // trigger unbinding from the port
.onComplete(_ => system.terminate()) // and shutdown when done
}
Solution:
When I was navigating to the "/" page, the redirect to the "/login" page happens due to the "document / redirect" request type (if analysing the network).
But, in case of redirecting from "/login" page to "/storage" page, the request is of type "xhr /redirect" that cannot be done on the server side, i.e. I had to add $(location).attr('href', 'storage') to my jQuery script to make it work.
i have the following akka http rejection handling code taken from https://doc.akka.io/docs/akka-http/current/routing-dsl/rejections.html
val message = "The requested resource could not be found."
implicit def myRejectionHandler = RejectionHandler.newBuilder()
.handleNotFound {
complete(HttpResponse(NotFound
,entity = HttpEntity(ContentTypes.`application/json`, s"""{"rejection": "$message"}"""
)))
}.result()
val route: Route = handleRejections(myRejectionHandler) {
handleExceptions(myExceptionHandler) {
concat(
path("event-by-id") {
get {
parameters('id.as[String]) {
id =>
complete("id")
}
}
}
,
post {
path("create-event") {
entity(as[Event]) {
event =>
complete(OK, "inserted")
}
}
}
)
}
}
}
val bindingFuture = Http().bindAndHandle(route, hostName, port)
when i hit localhost:8080/random
i got the message
HTTP method not allowed, supported methods: POST
and when i select POST and hit localhost:8080/random
i got the message
{
"rejection": "The requested resource could not be found."
}
why i did not get the same message when my route request was GET ?
in the docs the handleNotFound was working with GET request https://doc.akka.io/docs/akka-http/current/routing-dsl/rejections.html
This is happens, probably because of order of directives, you are using: in your configuration if incoming request does not match with event-by-id URL path, then it goes to the next handler, which expects that request should have POST method first of all, because post directive goes first, before path("create-event").
What you can try to do is change directives order to the next one, for second route:
path("create-event") {
post {
entity(as[Event]) { event =>
complete(OK, "inserted")
}
}
}
Hope this helps!
I have an Akka HTTP daemon. Assume that I want to receive some client data in JSON format and save it into a database asynchronously. I wrote a route in a POST branch:
path("product") {
entity(as[String]) { json =>
val saveFuture: Future[Unit] = Serialization.read[Product](json).save()
complete("")
}
}
I've found that complete can be put into an onSuccess statement like:
path("success") {
onSuccess(Future { "Ok" }) { extraction =>
complete(extraction)
}
}
But I can't understand how to glue them together.
You can nest the directives:
path("product") {
entity(as[String]) { json =>
val saveFuture: Future[Unit] = Serialization.read[Product](json).save()
onSuccess(saveFuture) {
complete("json was saved")
}
}
}
I am trying a basic authentication on post request in spray.io 1.3.2 using authenticate directive. My code looks following:
val route: Route = {
pathPrefix("ato") {
pathPrefix("v1") {
path("orders" / "updateStatus") {
post {
authenticate(BasicAuth(userPasswordAuthenticator _, realm = "bd ato import api")) {
user =>
entity(as[String]) {e =>
complete {
s"Hello $e "
}
}
}
}
}
}
}
}
def userPasswordAuthenticator(userPass: Option[UserPass]): Future[Option[String]] =
Future {
if (userPass.exists(up => up.user == ato_import_v1_usr && up.pass == ato_import_v1_pwd)) Some("ato_v1")
else None
}
This works perfectly fine, authorized Status Ok 200, unauthorized 401. However when the order of directives is changed as follows:
val route: Route = {
pathPrefix("ato") {
pathPrefix("v1") {
authenticate(BasicAuth(userPasswordAuthenticator _, realm = "bd ato import api")) {
user =>
path("orders" / "updateStatus") {
post {
entity(as[String]) {e =>
complete {
s"Hello $e "
}
}
}
}
}
}
}
}
I am getting Status 405, HTTP method not allowed for unauthorized access. I am not sure why that happens. From certain point it make sense, path is not matched because of missing credentials etc.
Could someone please clarify that?
The reason why I wanted to put authorization at v1 level is that I wanted to make every version protected by different password. Is there a way how to achieve that? What is the best practice in chaining directives?
I would like to follow DRY principle.
Thanks
i am trying to insert data from form to database but on form submission control does not enter in fold(error, success) method and runs the statement after it and redirects it to other page
this is my controller method
def submitinfo = Action { implicit request =>
signupForm.bindFromRequest().fold(
errors => BadRequest(views.html.signup(errors)),
data => {
println("************enter sucess case *********************")
signupcc.insertData(data.name, data.username, data.email, data.password)
})
println("************Redirecting to sucess page *********************")
Redirect(routes.Application.success)
}
here is my routes file
# Home page
GET / controllers.Application.index
GET /signup controllers.Application.signup
POST /submit controllers.Application.submitinfo
GET /success controllers.Application.success
GET /signin controllers.Application.signin
please tell me what i am doing wrong
Redirect action should be part of sucess case inside fold method:
def submitinfo = Action { implicit request =>
signupForm.bindFromRequest().fold(errors => BadRequest(views.html.signup(errors)),
data => {
println("************enter sucess case *********************")
signupcc.insertData(data.name, data.username, data.email, data.password)
println("************Redirecting to sucess page *********************")
Redirect(routes.Application.success)
})
}
