ESP32 OTA read local files

Question

I have this code in html, which has a form to send files, but I would like to read these files directly from a path on the computer, how do I do that? I'm new to the language Thanks

const char* serverIndex = 
"<script src='https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js'></script>"
"<form method='POST' action='#' enctype='multipart/form-data' id='upload_form'>"
   "<input type='file' name='update'>"      
    "</form>"
 "<div id='prg'>Progresso: 0%</div>"
 "<script>"
  "$('form').submit(function(e){"
  "e.preventDefault();"
  "var form = $('#upload_form')[0];"
  "var data = new FormData(form);"
  " $.ajax({"
  "url: '/update',"
  "type: 'POST',"
  "data: data,"
  "contentType: false,"
  "processData:false,"
  "xhr: function() {"
  "var xhr = new window.XMLHttpRequest();"
  "xhr.upload.addEventListener('progress', function(evt) {"
  "if (evt.lengthComputable) {"
  "var per = evt.loaded / evt.total;"
  "$('#prg').html('Progresso: ' + Math.round(per*100) + '%');"
  "}"
  "}, false);"
  "return xhr;"
  "},"
  "success:function(d, s) {"
  "console.log('Sucesso!')"
 "},"
 "error: function (a, b, c) {"
 "}"
 "});"
 "});"
 "</script>";

Example:

I would like to read this file file:///C:/Users/Matheus/Desktop/test.bin

Are you saying that the form works but you want to be able to have your web page read files from the computer without using the form or having any user interaction? — romkey, Nov 15 '22 at 22:32
