Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

localhost Not Serving


The game runs great until it gets to the point where I submit my score to a leaderboard, thats when the HTML5LaunchHelper.exe displays the 'Not Serving' message and the score never gets submitted.

alt text

The score is submitted using the HTTP Post request below:


 #pragma once
 #include "GameFramework/Actor.h"
 #include "Runtime/Online/HTTP/Public/Http.h"
 #include "HttpRequest.generated.h"
 UCLASS(ClassGroup = (Custom), meta = (BlueprintSpawnableComponent))
 class BLINDSCOMGAME_API UHttpRequest : public UActorComponent
     FHttpModule* Http;
     //UPROPERTY(EditAnywhere, BlueprintReadWrite, Category=Custom)
     //FString URLName;
     // The actual HTTP call
     UFUNCTION(BlueprintCallable, Category=Custom)
     void MyHttpCall(FString URLName);
     // Assign this function to call when the GET request processes sucessfully
     void OnResponseReceived(FHttpRequestPtr Request, FHttpResponsePtr Response, bool bWasSuccessful);
     // Set Default Values for this Actor's properties
     UHttpRequest(const class FObjectInitializer& ObjectInitializer);
     // Called when the game starts or when spawned
     virtual void BeginPlay() override;


 #include "Game.h"
 #include "HttpRequest.h"
 // Sets default values
 UHttpRequest::UHttpRequest(const class FObjectInitializer& ObjectInitializer)
     : Super(ObjectInitializer)
     // When the object is constructed, get the HTTP module
     Http = &FHttpModule::Get();
 // Called when the game starts or when spawned
 void UHttpRequest::BeginPlay()
 void UHttpRequest::MyHttpCall(FString URLName)
     TSharedRef<IHttpRequest> Request = Http->CreateRequest();
     Request->OnProcessRequestComplete().BindUObject(this, &UHttpRequest::OnResponseReceived);
     //Request->SetHeader(TEXT("User-Agent"), "X-UnrealEngine-Agent");
     //Request->SetHeader("Content-Type", TEXT("application/json"));
 //Assigned function on successfull http call
 void UHttpRequest::OnResponseReceived(FHttpRequestPtr Request, FHttpResponsePtr Response, bool bWasSuccessful)
     //Create a pointer to hold the json serialized data
     TSharedPtr<FJsonObject> JsonObject;
     //Create a reader pointer to read the json data
     TSharedRef<TJsonReader<>> Reader = TJsonReaderFactory<>::Create(Response->GetContentAsString());
     //Deserialize the json data given reader and the actual object to deserialize
     if (FJsonSerializer::Deserialize(Reader, JsonObject))
         //Get the value of the json object by field name
         int32 recievedInt = JsonObject->GetIntegerField("seconds");
         //Output it to the engine
         GEngine->AddOnScreenDebugMessage(1, 2.0f, FColor::Green, FString::FromInt(recievedInt));

Anyone else experience this problem or something similar? I've got no idea what is causing the host not to serve the URL

Any and all ideas are welcome!

hello haxo

the URL you are accessing is external to the "original" host (local or webhosted -- doesn't matter) -- the URL you've passed in is "relative" to the "original" host.

for example, you are using URL: "dreamlo.com/lb/secret-key/add/bla/bla/bla.."

this is NOT the same as using URL: "http://dreamlo.com/lb/secret-key/add/bla/bla/bla..."

that should fix your issue. (just in case it's not obvious -- use the 2nd URL example above -- the one with the "http://" protocol in front)

Thanks for the answer Nick! That did get rid of my 'Not Serving' error. The score still isn't making it onto the dreamlo leaderboard though.

I know MyHttpCall works in a PC build and in the editor. Wonder what is stopping it on HTML5.
