I have tried get_args(), get_headers(), and get_footers(). However if i dump the body with get_content(), I can see the fields in the body, but they are not hoisted into higher level objects. \r\n\r\n### Example Code\r\n```c++\r\n#include \u003ciostream\u003e\r\n#include \u003calgorithm\u003e\r\n\r\n#include \u003chttpserver.hpp\u003e\r\n\r\nusing namespace httpserver;\r\n\r\nclass file_resource : public http_resource {\r\n  public :\r\n    const std::shared_ptr\u003chttp_response\u003e render_POST(const http_request\u0026 req) {\r\n\r\n      //Loop through the headers map and output them\r\n      const auto\u0026 headers = req.get_headers();\r\n      std::for_each(headers.begin(), headers.end(), [](auto\u0026 p){\r\n        std::cout \u003c\u003c p.first \u003c\u003c \" -\u003e \" \u003c\u003c p.second \u003c\u003c std::endl;\r\n      });\r\n\r\n      //Loop through the args map and output them\r\n      const auto\u0026 args = req.get_args(); \r\n      std::for_each(args.begin(), args.end(), [](auto\u0026 p) {\r\n        std::cout \u003c\u003c p.first \u003c\u003c \" -\u003e \" \u003c\u003c p.second \u003c\u003c std::endl;\r\n      });\r\n\r\n      std::cout \u003c\u003c \"Body: \" \u003c\u003c req.get_content() \u003c\u003c std::endl;\r\n      return std::shared_ptr\u003chttp_response\u003e(new string_response(\"OK\"));\r\n    }\r\n};\r\n\r\nvoid custom_access_log(const std::string\u0026 url) {\r\n  std::cout \u003c\u003c \"Request to: \" \u003c\u003c  url \u003c\u003c std::endl;\r\n}\r\n\r\nvoid custom_error_log(const std::string\u0026 error) {\r\n  std::cout \u003c\u003c \"Error: \" \u003c\u003c error \u003c\u003c std::endl;\r\n}\r\n\r\nint main() {\r\n  webserver ws = create_webserver(8080)\r\n    .log_access(custom_access_log)\r\n    .log_error(custom_error_log);\r\n\r\n  file_resource fr;\r\n\r\n  ws.register_resource(\"/file\", \u0026fr);\r\n\r\n  ws.start(true);\r\n\r\n  return 0;\r\n}\r\n```\r\n\r\n### Steps to Reproduce\r\n\r\n1. Compile example code above\r\n2. `curl -X POST -F upload=@\u003csome_file\u003e.jpg localhost:8080/file`\r\n3. the \"upload\" argument will have the file data, but the Content-Type, and original filename are not accessible \r\n4. Looking at the output, you can see the get_contents() string contains the Content-Type and filename\r\n```\r\nMethod: POST, Body: --------------------------ea9b4d3e74b2950b\r\nContent-Disposition: form-data; name=\"upload\"; filename=\"suite_and_tie.jpg\"\r\nContent-Type: image/jpeg\r\n```\r\n\r\n**Expected behavior:** \r\nSome way to access the filename and Content-Type of the file \r\n\r\n**Actual behavior:** \r\nNo way to access it easily\r\n\r\n**Reproduces how often:** 100%\r\n","author":{"url":"https://github.com/jmslocum","@type":"Person","name":"jmslocum"},"datePublished":"2021-04-10T01:34:27.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":12},"url":"https://github.com/229/libhttpserver/issues/229"}
