    Creating DLL with HTTP functionalities in Unreal

    Hello,

    Aim: Creating an C++ DLL with HTTP functionalities in visual studio and using that in Unreal Engine.

    Approaches tried:

    APPROACH-1: (Using Visual Studio 2017 directly for creating a DLL)
    1.Tried creating normal DLL with math functionalities just for testing and it works fine in unreal on importing it.
    2.Created HTTP functions in VS-2017 and faced lots of errors(Lib files missing) so i tried using CppRest SDK but still left with same.
    Note: Need to know will HTTP functionalities created with basic c++ using some SDK work on Unreal on importing it ?

    APPROACH-2: (Using Unreal to create a DLL)
    1.Created HTTP features directly in Unreal and they are working fine.
    2.Created a empty unreal project and and added a class to it. *Open the class in visual studio and create one more class via visual studio which will be turned into DLL. *Create HTTP functionalities in the newly created class via VS.(same errors - lib files missing)
    So for this issue we need to link all unreal libraries.


    is there any way to achieve this ?

    Thanks

    In UE4 you can use winhttp of windows. #include <winhttp.h>

    use dll?
    1.
    #include "absolute path"
    #pragma comment(lib,"absolute path")
    2.
    copy you dll to runtime of UE4.
    debug and run (copy to): ??\??\Engine\Binaries\Win64
    release and packing (copy to): WindowsNoEditor"you exe name"\Binaries\Win64
