UE4 WCF RestFul 服务器 读取JSON 数据并解析 简单实例

Note:如果通过Txt读取的JsonString，如果TXT 不是ANSI编码的话，会报JsonArrayStringToUStruct  Unable to parse。(4.13出，不知道是不是我电脑的个例)

 Build.cs 包含 JsonUtilities 模块。

UE4:

bool UWgtCpp_BaseMain::Http_readSortList()
{
    auto temp_request = UNetAPI::createRequst(TEXT("http://localhost:59754/StudentService.svc/GetStudentList"), TEXT("GET"));
 
    temp_request->OnProcessRequestComplete().BindUObject(this, &UWgtCpp_BaseMain::OnArrSortListLoaded);
    temp_request->ProcessRequest();
 
    return true;
}
 
void UWgtCpp_BaseMain::OnArrSortListLoaded(FHttpRequestPtr _request, FHttpResponsePtr _response, bool bWasSuccessful)
{
    UE_LOG(LogTemp, Warning, TEXT("OnArrSortListLoaded"));
    if (bWasSuccessful)
    {
        switch (_response->GetResponseCode())
        {
        case :
            TArray<FDataCpp_BaseSortItem> arr;
 
            FJsonObjectConverter::JsonArrayStringToUStruct<FDataCpp_BaseSortItem>(_response->GetContentAsString(), &arr, ,);
 
            for (auto item : arr)
            {
                auto temp_str = FString::Printf(TEXT("%d , %s"),item.id , item.Name);
                GEngine->AddOnScreenDebugMessage(-, 5.0f, FColor::Cyan, item.Name);
            }
 
            break;
        }
    }
}

 

WCF：

        [OperationContract]
        [WebInvoke
            (
            Method = "GET",
            RequestFormat = WebMessageFormat.Json,
            ResponseFormat = WebMessageFormat.Json,
            UriTemplate = "GetStudentList"
            )
        ]
        IList<Student> GetStudentList();
