Uploading files

Uploading files requires the use Multipart, with xxhr this is really simple.

Given a web server expecting a field named somefile an xxhr::File or xxhr::Buffer can be passed as in the following example.

  POST("http://httpbin.org/post"s, 
    
    Multipart{
      {"somefile", File{"../../../xxhr/api.hpp"} }
    },
 
    on_response = [](auto&& resp) {
      std::cout << resp.text;
      std::cout << "Upload status : " << resp.error << " - " << resp.status_code << "\n";
    });

Multiple files at once

It is possible, as it is a Multipart query to add many xxhr::File or xxhr::Buffer.

  auto buffer = "this is some buffer"s;
 
  POST("http://httpbin.org/post"s, 
    
    Multipart{
      {"somefile", File{"../../../xxhr/api.hpp"} }
      , {"other", File{"../../../xxhr/multipart.hpp"} }
      , {"and_another", File{"../../../README.md"} }
      , {"somebuffer", Buffer{buffer.begin(), buffer.end(), "IN_MEMORY_FILE"} }
    },
