IHttpRequest::ProcessRequest on Android Crash

I’m trying to make HTTP-request on Android build.

void UHttpAdapter::SendHttpRequest(const FString& URL, EHttpMethodType Method, const FString& Content, FOnHttpRequestSuccess Success, FOnHttpRequestFailed Failed)
{
	auto MethodName = UCommonUtils::GetEnumValueAsString(TEXT("EHttpMethodType"), Method);

	auto OnResponseReceived = [Success, Failed](FHttpRequestPtr Request, FHttpResponsePtr Response, bool bWasSuccessful)
		{
			UE_LOG(LogHttpAdapter, Log, TEXT("Response from %s : %s"), *Request->GetURL(), bWasSuccessful ? TEXT("success") : TEXT("failed"));

			if (bWasSuccessful) 
				Success.ExecuteIfBound(Response->GetContentAsString());
			else
				Failed.ExecuteIfBound();
		};

	auto Http = &FHttpModule::Get();

	auto Request = Http->CreateRequest();

	Request->SetURL(*URL);
	Request->SetVerb(*MethodName);
	Request->SetHeader(TEXT("User-Agent"), TEXT("X-UnrealEngine-Agent"));
	Request->SetHeader(TEXT("Content-Type"), TEXT("application/json"));
	
	if (Method == EHttpMethodType::HM_POST)
		Request->SetContentAsString(*Content);

	Request->OnProcessRequestComplete().BindLambda(OnResponseReceived);

	if (!Request->ProcessRequest())
		Failed.ExecuteIfBound();

	//auto Response = Request->GetResponse();

	UE_LOG(LogHttpAdapter, Log, TEXT("Request to %s by %s"), *Request->GetURL(), *MethodName);
}

But app will crashed on Request->ProcessRequest() call on Android.

Windows build and in Editor works correct.

I thinks about problem with libcurl… but all links are correct

Someone can hepl me with this?
Maybe I need use some another way to call http-request?

Also… Socket connection by FTcpSocketBuilder().Build()->Connect(IpAddr) works correct. This is not a problem with network.

Oh… it… was…

I found error - for some reason MethodName in Request->SetVerb(*MethodName) was incorrect on Android builds, but everything Ok in Editor.

Could you tell me a bit more how you set this up? Somehow this is not working on my end and I’m searching for houers for a solution. It works well on Windows and the Mobile Preview Window but on the actual Android it seams that the http module is not working. I get absolute no answer from the request. Could this be a problem with the signature of the app?

here is my full solution

header

#pragma once

#include "CoreMinimal.h"
#include "HttpAdapter.generated.h"

DECLARE_LOG_CATEGORY_EXTERN(LogHttpAdapter, Log, All);

UENUM(BlueprintType)
enum class EHttpMethodType : uint8
{
	GET	 	UMETA(DisplayName = "GET"),
	POST 	UMETA(DisplayName = "POST")
};

DECLARE_DYNAMIC_DELEGATE_OneParam(FOnHttpRequestSuccess, FString, Response);
DECLARE_DYNAMIC_DELEGATE(FOnHttpRequestFailed);

UCLASS()
class MOBAGAME_API UHttpAdapter : public UObject
{
	GENERATED_BODY()

public: 
	UFUNCTION(BlueprintCallable, Category = "HttpAdapter")
		static void SendHttpRequest(const FString& URL, EHttpMethodType Method, const FString& Content, FOnHttpRequestSuccess Success, FOnHttpRequestFailed Failed);
};

source

#include "HttpAdapter.h"
#include "HttpModule.h"
#include "IHttpResponse.h"
#include "Utils/CommonUtils.h"

DEFINE_LOG_CATEGORY(LogHttpAdapter);

void UHttpAdapter::SendHttpRequest(const FString& URL, EHttpMethodType Method, const FString& Content, FOnHttpRequestSuccess Success, FOnHttpRequestFailed Failed)

	auto MethodName = UCommonUtils::GetEnumValueAsString(TEXT("EHttpMethodType"), Method);

	auto OnResponseReceived = [Success, Failed](FHttpRequestPtr Request, FHttpResponsePtr Response, bool bWasSuccessful)
		{
			if (bWasSuccessful) 
				Success.ExecuteIfBound(Response->GetContentAsString());
			else
				Failed.ExecuteIfBound();
		};

	auto Http = &FHttpModule::Get();

	auto Request = Http->CreateRequest();

	Request->SetURL(*URL);
	Request->SetVerb(*MethodName);
	Request->SetHeader(TEXT("User-Agent"), TEXT("X-UnrealEngine-Agent"));
	Request->SetHeader(TEXT("Content-Type"), TEXT("application/json"));
	
	if (Method == EHttpMethodType::POST)
		Request->SetContentAsString(*Content);

	Request->OnProcessRequestComplete().BindLambda(OnResponseReceived);

	if (!Request->ProcessRequest())
		Failed.ExecuteIfBound();
}

wow, thank you very much! Very kind of you to share your code. mine looks not that different from yours. I’ll try to use your code directly in the project I’m working on. Right now I have the code in a plugin which might be a problem
