如何在不使用 sockets 的情况下在 C ++ 中发送 POST 请求

Question

I have python code that sends a POST request and gets a json, I need to rewrite it in C ++ (Windows 10, Visual Studio 2019). I don't understand what tools can really do everything I need without complicating the code.

There will be a console application that must send a request to send or receive data, more precisely a video stream. I read about Boost.Asio, but it seems to work only with sockets, is there any way without them? At first I wanted to use it, as the most famous. I read about сurl, but it hasn't been updated for a long time, is it still relevant?

    headers_predict = {
        "Content-type": "application/json;charset=UTF-8",
        "Accept": "application/json",
        "X-Session-ID": session_id
        }
    data_predict = {
      "audio": {
          "data": sound_base64,
          "mime": "audio/pcm16"
          },
      "package_id": ""
      }
    url = 'https://cp.speechpro.com/recognize'
    r = requests.post(url, headers=headers_predict, 
    data=json.dumps(data_predict))
    print('Response: %s' % r.text)

I wouldn't want to use sockets, because I don't understand them. I need to be able to set the header and data as a json.

Answer 1

sockets, is there any way without them?

Technically, HTTP does not specify the underlying transport protocol and it can work with any sort of streaming transport. You could for example write the request into a file.

But, if you currently use TCP and don't want to change that, then you must use sockets. You don't need to interact with them directly if you use an existing HTTP client library.
