You should

use SSL, usually with SNI
not append the port to the hostname for WS handshake (mildly surprising)
use a proper endpoint url, from the same docs:
The base endpoint is: wss://stream.binance.com:9443
- Streams can be accessed either in a single raw stream or in a combined stream
- Raw streams are accessed at /ws/
- Combined streams are accessed at /stream?streams=//
- Combined stream events are wrapped as follows: {"stream":"","data":}

I just guessed a stream name (wss://stream.binance.com:9443/ws/btcusdt), added some code to print the received/sent messages:

QUESTION

Boost Beast Async Websocket Server How to interface with session?

Asked 2022-Apr-04 at 01:25

So I don't know why but I can't wrap my head around the boost Beast websocket server and how you can (or should) interact with it.

The basic program I made looks like this, across 2 classes (WebSocketListener and WebSocketSession) https://www.boost.org/doc/libs/develop/libs/beast/example/websocket/server/async/websocket_server_async.cpp

Everything works great, I can connect, and it echos messages. We will only ever have 1 active session, and I'm struggling to understand how I can interface with this session from outside its class, in my int main() for example or another class that may be responsible for issuing read/writes. We will be using a simple Command design pattern of commands async coming into a buffer that get processed against hardware and then async_write back out the results. The reading and queuing is straight forward and will be done in the WebsocketSession, but everything I see for write is just reading/writing directly inside the session and not getting external input.

I've seen examples using things like boost::asio::async_write(socket, buffer, ...) but I'm struggling to understand how I get a reference to said socket when the session is created by the listener itself.

Instead of depending on a socket from outside of the session, I'd depend on your program logic to implement the session.

That's because the session (connection) will govern its own lifetime, arriving spontaneously and potentially disconnecting spontaneously. Your hardware, most likely, doesn't.

So, borrowing the concept of "Dependency Injection" tell your listener about your application logic, and then call into that from the session. (The listener will "inject" the dependency into each newly created session).

Let's start from a simplified/modernized version of your linked example.

Now, where we prepare a response, you want your own logic injected, so let's write it how we would imagine it:

The link you are passing is not a link to an Image instead it is a url to a page,

to get an Image link you have to right click and select Open image in new tab

and after that you will see this url which is an actual link to image http://pm1.narvii.com/6439/ecfa73c34db4039a4dd92481ea16a180a18608ed_00.jpg

and this is an actual image link because it will have an extension of image at the end

I hope this will solve your problem :)

Using Boost Beast to build Platform specific client-side authentication in SSL connection

Asked 2022-Mar-21 at 08:09

I’m working on boost::beast based application on macOS platform, and I wonder how I can provide a client-side certificate to authenticate against the server ?

basically , in macOS the certificates are stored in keychain, and cannot be exported (backed by dedicated hardware called secured-enclave for better security)…

So I wonder if there’s any callback suitable to sign server’s challenge manually with native macOS native code that send the challenge to the keychain/secure-enclave for signing.

basically, I'm looking for a callback that have roughly the following signature :

See set_verify_callback

There are examples here:

asio/example/cpp11/ssl/client.cpp

You can see it integrated in Beast's ssl_stream: https://www.boost.org/doc/libs/1_78_0/libs/beast/doc/html/beast/ref/boost__beast__ssl_stream/set_verify_callback/overload2.html

Understand the usage of strand without locking

Asked 2022-Mar-19 at 04:33

Reference: websocket_client_async_ssl.cpp strands

Question 1> Here is my understanding:

Given a few async operations bound with the same strand, the strand will guarantee that all associated async operations will be executed as a strictly sequential invocation.

Does this mean that all above async operations will be executed by a same thread? Or it just says that at any time, only one asyn operation will be executed by any available thread?

Question 2> The boost::asio::make_strand function creates a strand object for an executor or execution context.

The latter.

Question 2

Here, resolver_ and ws_ have its own strand,

Let me interject that I think that's unnecessarily confusing in the example. They could (should, conceptually) have used the same strand, but I guess they didn't want to go through the trouble of storing a strand. I'd probably have written:

I don't see any Beast types here. It's all exclusively Asio.

Also, streambuf models the DynamicBuffer concept. It has no fixed size, so your claim is not accurate.

Finally, no matter how big the initial capacity of the streambuf were to be, it won't do you much good because you instruct the async_read to transfer_at_least(1), which means that any platform-dependent buffer in the underlying implementations will probably cause the first read_some to return much smaller quantity. E.g. with this simple server:
