Hi,

I am using a RESTful web service where I would like to add data from our unreal game client.  
I have read the official documentation and some other threads on how to send those requests to a server([Get Http Module to work with HTTPS](https://answers.unrealengine.com/questions/225817/view.html)[How to Make Http GET request in C++](https://wiki.unrealengine.com/UE4.10_How_To_Make_HTTP_GET_Request_in_C%2B%2B)), am still not sure if the order of instructions matters, please let me know if what I am using look correct

```
	TSharedRef<IHttpRequest> Request = HttpModule->CreateRequest();
	Request->SetHeader(TEXT("Content-Type"), TEXT("application/json"));
	Request->SetURL("https://user:pass@mysite.com:445");
	Request->SetVerb("GET");
	Request->OnProcessRequestComplete().BindUObject(this, &AMyGameMode::OnResponseReceived);
	Request->ProcessRequest();

```

I get an OK response from the server when executing the above, apparently the authentication is correct.

The problem arises when I start using any content in the request (either SetContentAsString, even from a file stream),  
you can read the full log in the log.txt file attachedlog error when requesting with content, sufficient to say  
that the server returns **libcurl error: 52 (Server returned nothing (no headers, no data))**

Even with the simplest body it return the same error, same with POST verbs, the ones I am interested in .

```
GET myndex/_search
{
}

```

Which translates into C++ code like

```
	FString content("myindex/_search {}");
	Request->SetContentAsString(content);

```

Even if the content is stored in a json file and passed as I get the same error, which verifies that my json format is correct.

```
Request->SetContentAsStreamedFile(myJsonFile);

```

Is there anything else left on my side, or would this be related to the server I am using?

Appreciate any help.  
Regards

This happened to me when using a “GET” verb and setting content via “SetContentAsString”. The resolution for me was instead to construct the URL with the appropriate query following the question mark ([http://myserver.local?myqueryparam=somethinghere](http://myserver.local?myqueryparam=somethinghere)), and not setting content on the request at all.

AFAIK Only set the content if you are using “POST” or “PUT”.
