Request headers

[Marcel1707]

Hello, I am using oatpp-websocket for a client connection and I need to pass some request headers at the initial connection. Is there a possibility to add request headers (like a token) to the connection?

Hello @Marcel1707 ,

Thanks for your question!

You can easily do it by doing the same steps as in the Connector::connect() - just add headers that you need to the map.

It might be also a good idea to extend Connector by adding a connect method with headers...

Hey,

I tried it with the following code but it still did not work. Do I have to replace the connect method completely?

    oatpp::base::Environment::init();
    std::cout << "application started" << std::endl;
    auto config = oatpp::mbedtls::Config::createDefaultClientConfigShared();
    auto connectionProvider = oatpp::mbedtls::client::ConnectionProvider::createShared(config, "192.168.1.106", 5000);
    auto connectionHandler = oatpp::websocket::ConnectionHandler::createShared();
    auto connector = oatpp::websocket::Connector::createShared(connectionProvider);

    try {
        oatpp::websocket::Handshaker::Headers headers;
        headers.put("Test", "Test");
        oatpp::websocket::Handshaker::clientsideHandshake(headers);
        auto connection = connector->connect("/");
        std::cout << "connected" << std::endl;
        auto socket = oatpp::websocket::WebSocket::createShared(connection, true);
        std::mutex socketWriteMutex;
        socket->setListener(std::make_shared<WSListener>(socketWriteMutex));
        std::cout << "listening ..." << std::endl;

        socket->listen();
    }
    catch (const std::exception& e) {
        std::cout << "connection error: " << e.what() << std::endl;
    }

Hey,

Yes, you have to replace the Connect method. You need to call execute method with your headers provided (like inside the connect method)

I'll provide the code snippet later today

Hey @Marcel1707 , did you manage to make it work?

[lganzzzo]

[TODO] Add possibility to pass headers to the Connector::connect() method.

[Marcel1707]

No I did some other things in the meantime hoping that you provide the code snippet :)

I came to another question: What is the easiest way to execute just a http request? Without using the APIClient..

Thanks and kind regards, Marcel

Hey,

I'll make a patch to oatpp-websocket tonight to make it possible to pass headers. And will put a code snippet here.

What is the easiest way to execute just a http request? Without using the APIClient..

The easiest way is to use HttpRequestExecutor directly - please find this answer

Regards, Leonid

[Marcel1707]

Ah great thanks :)

I am currently trying to make the request with HttpRequestExecutor but I cant manage to add a request body in JSON format. I tried to use a BufferBody with the JSON string and text/json as content type but on the server the body is always empty.

Kind regards, Marcel

Hey,

I tried to use a BufferBody with the JSON string and text/json as content type but on the server the body is always empty.

It sounds correct except that the content-type header should be application/json. Please provide your code snippet.

Regards, Leonid

[Marcel1707]

Oh thanks, with 'application/json' it works 👍

Hey @Marcel1707 ,

I've made a patch to pass headers in the WS connect request. Please checkout the latest oatpp-websocker master branch.

oatpp::web::protocol::http::Headers headers;
headers.put("X-MyHeader", "MyValue");
auto connection = connector->connect("/", headers /* pass headers here */);

I'm closing this issue. @Marcel1707 marcel please feel free to reopen or to create the new one in case it doesn't work for you.
