Boost.Beast VS cpr

There is at least one notable exception to this rule: https://github.com/boostorg/beast/issues/1445

I am using this example : https://github.com/boostorg/beast/blob/develop/example/websocket/client/async-ssl/websocket_client_async_ssl.cpp My application is listening to tick data streams of crypto exchanges over the websockets and processing and sending orders to the exchange.

We used beast to implement a market data server(and I think we also did a small client, to test it) which was sending protobuf messages, and it worked great(we also used boost adio, which made it very scalable). When we tested the server, we were generating around 100k messages per second(when there was the biggest activity on the market), I think I've posted here some stats: https://github.com/boostorg/beast/issues/2313.

Boost Beast?

And Chris wrote this example, which is faster than any of my other examples: https://github.com/boostorg/beast/tree/21cd552399aa8167ed53c21a74f3711c2c316d2f/example/http/server/fast

cmake -h. -Bbuild && cmake --build build

to work about 90% of the time. Far more luck than I've had with autotools.

> Its code is horrifying too, for example:

1) I'm sure I could find some horriffic code in meson too if I went digging. 2) The alternative to this is you having to write something equivalent in your own code, meaning that in my code I don't need to do stuff like [0] in my code to detect features; my build system handles it for me. 3) CMake supports more platforms and targets than I've ever seen in my life, and likely supports more compilers than are necessary. that's a blessing and a curse, but it means that if I write simple program to run on some crufty microcontroller with a bastardised gcc toolchain from the 90s, it's fairly likely that cmake supports it out of the box. Code like that is the price to pay for that level of support.

If you need an embedded C++ HTTP server then there are plenty of libraries/frameworks (in random order): Crow, RESTinio, Boost.Beast, cpp-httplib, http_backend, Pistache, RestBed, served, proxygen, Simple-Web-Server, drogon, oat++.

This one might fit the bill https://github.com/libcpr/cpr

There is also the cpr package which should offer a more c++ focussed interface for curl.

So I'm very new to C++ and I'm trying to write a C++ version of a tool that I put together in Python. I'm trying to use libcpr for all my HTTP needs. I've spent the day trying to get it set up and working, but I'm getting a bunch of linking errors when I try to run. I really don't know if I did the building of it correctly, I'm trying to use Visual Studio Community 2022 and the Usage section of their docs talks about CMake and a couple package manager methods.

I think vcpkg manifests have solved a really key portion of the "please give me these libraries" problem. Couple lines in a json file, pass CMake to your vcpkg toolchain script path and triplet, and you're pretty much done with dependencies. I actually used it for a project with libcpr/cpr and a couple other popular libraries, and I was shocked at how painless it was to get up and running with some web request stuff.

Libraries like nlohmann's json, cpr, fmt are prime examples of what I'm seeking. Any suggestions?

Basically specifying the language and the repo, and it does work when the request is made from postman or from the browser. However, when using https://github.com/libcpr/cpr, I'm getting the following response:
