ESP32 filesystem error

[DmitryBorisenko33]

I have problem with spiffs file system. I am using standard example "FSBrowser"
But files in "data" folder (html, js, css) i am using not like in example. This is my files. This files perfectly running on esp8266 with the same sketch. But when i start using esp32 i have errors during web page refresh.

Here is a link to the file system that I use

Sometimes page stopped like this:

"File not Found" but this file exactly exist!!

Sometimes going less:

I have now big problem with this. My project is stopped... Please kindly help me. I have already read many information and forums but cant find how to resolve this problem. I found many people who have now same problem.

[lbernstone]

You need to post logs from the esp32 side. Turn on verbose debug and upload your sketch again. Post the serial monitor logging during the file request. Also please include all the hardware information requested in the ISSUE_TEMPLATE.
File locations in esp32 must always start with a /

I am author of ESP8266 + IOTmanager application modules firmware
This is my project
This is our application now we working on ver 2 this application
Now i trying to transfer my project from esp8266 to esp32
I am using arduino ide 1.8.9 and ESP32 arduino core 1.0.4

For your information my file system is here and i have some folders in it: css, js, lang

This is screenshot of my file system:

This is youtube video with my problem demonstration

Please help me.

[DmitryBorisenko33]

Please look at my issue. Im sorry, i really need your help!

@DmitryBorisenko33

• you haven't posted your code
  How do you expect up to identify problems in your code if we can't see it?
• you have not registered any request handlers: server.on()
  The error log you posted show:

The WebServer is unpacking the index.htm.gz properly. The contents of that html/js are not correct. The server has no handler for the parameters that are going along with the GET requests for those files (css/build.js?v07.04.2018 vs css/build.js) so it fails. Either set up a handler for them in the esp32 code, or request without the parameter.

When i use this the same code with the same file system on esp8266 everything working well.
But with esp32 i have problems.

[lbernstone]

esp32 != esp8266. If you want to ensure compatibility, I would recommend using https://github.com/me-no-dev/ESPAsyncWebServer/blob/master/examples/ESP_AsyncFSBrowser/ESP_AsyncFSBrowser.ino, which is supported from the same code base on both platforms.

[DmitryBorisenko33]

I understood your recommendation about ESP_AsyncFSBrowser. It is really good and i will try it. But anyway i want to resolve this problem. I make new code and video for you.

This is my new code:

  }, handleFileUpload);

  //called when the url is not defined here
  //use it to load content from FILESYSTEM
  HTTP.onNotFound([]() {
    if (!handleFileRead(HTTP.uri())) {
      HTTP.send(404, "text/plain", "FileNotFound");
    }
  });

Two case.

one - refresh page by arrow - file system working fully
two - refresh page by refresh button or first start - file system not working

[DmitryBorisenko33]

Please dont forget look my video! its very important to understand.
link to youtube

[DmitryBorisenko33]

Some people here had a same problem. But they were not resolve it.

[me-no-dev]

in your code you do not have handlers for those files. it's quite simple :) pasting your setup() would be enough in that case. how you expect the server to find your files? because the FSBrowser does?
there is plenty info in the readme of the async web server for you to solve this :)

[DmitryBorisenko33]

I have handlers for this file in my code:

 void handleFileList() {
  if (!HTTP.hasArg("dir")) {
    HTTP.send(500, "text/plain", "BAD ARGS");
    return;
  }

  String path = HTTP.arg("dir");

  File root = FILESYSTEM.open(path);
  path = String();

  String output = "[";
  if(root.isDirectory()){
      File file = root.openNextFile();
      while(file){
          if (output != "[") {
            output += ',';
          }
          output += "{\"type\":\"";
          output += (file.isDirectory()) ? "dir" : "file";
          output += "\",\"name\":\"";
          output += String(file.name()).substring(1);
          output += "\"}";
          file = root.openNextFile();
      }
  }
  output += "]";
  HTTP.send(200, "text/json", output);
}

But anyway as per recommendation above, i already start AsyncWebServer. And my file system working properly and fully. Thank you so match for this recommendation.

AsyncWebServer more good and have login and password identification.
