How to disable file upload in arduino

Projects Programming

Hey guys,

How could I block through some if() within the arduino code the UPDATE.

When I upload a file to the web server page and click UPLOAD nothing should happen. Progress (1 to 100%) must not evolve.

I use this basic UPDATE configuration:

server.on("/update", HTTP_POST, []() {
    server.sendHeader("Connection", "close");
     server.send(200, "text/plain", (Update.hasError()) ? "FAIL" : "OK");
      ESP.restart();
   }, []() {
    HTTPUpload& upload = server.upload();
    if (upload.status == UPLOAD_FILE_START) {
      Serial.printf("Update: %s\n", upload.filename.c_str());
      if (!Update.begin(UPDATE_SIZE_UNKNOWN)) {
        Update.printError(Serial);
      }
    } else if (upload.status == UPLOAD_FILE_WRITE) {
      if (Update.write(upload.buf, upload.currentSize) != upload.currentSize) {
        Update.printError(Serial);
      }
    } else if (upload.status == UPLOAD_FILE_END) {
      if (Update.end(true)) { //para definir o tamanho para o progresso atual
        Serial.printf("Update Success: %u\nRebooting...\n", upload.totalSize);
      } else {
        Update.printError(Serial);
      }
    }
  });

Well if you want to block the initialization of the process, you can do

server.on("/update", HTTP_POST, []() {
    server.sendHeader("Connection", "close");
     server.send(200, "text/plain", (Update.hasError()) ? "FAIL" : "OK");
      ESP.restart();
   }, []() {
    if (!server.authenticate("user", "password")) {
      return server.requestAuthentication();
      // or just
      // server.send(200, "text/plain","Upload Blocked");
     // return;
    }
    HTTPUpload& upload = server.upload();  // this is where the process is actually started.
    if (upload.status == UPLOAD_FILE_START) {
      Serial.printf("Update: %s\n", upload.filename.c_str());
      if (!Update.begin(UPDATE_SIZE_UNKNOWN)) {
        Update.printError(Serial);
      }
    } else if (upload.status == UPLOAD_FILE_WRITE) {
      if (Update.write(upload.buf, upload.currentSize) != upload.currentSize) {
        Update.printError(Serial);
      }
    } else if (upload.status == UPLOAD_FILE_END) {
      if (Update.end(true)) { //para definir o tamanho para o progresso atual
        Serial.printf("Update Success: %u\nRebooting...\n", upload.totalSize);
      } else {
        Update.printError(Serial);
      }
    }
  });

Of course the actual initialization starts with the navigation and the choosing of the file, followed by the "POST" request.

Tested. Progress even evolves but in fact when it reaches 100% nothing happens. And that's what I needed. Thank you very much.
