FTPServer c++ class usage

[snahmad]

Hi,

How to use FTPServer with example to use with spi flash and with sd card.

I also getting linker error. getcwd and chdir. I need to give function definitions for these. Can you provide example function definitions for these.

I managed to add

int chdir(const char *path) { FRESULT result = f_chdir(path); return result == FR_OK ? 0 : -1; }

char getcwd(char buf, size_t size) { FRESULT result = f_getcwd(buf, size); return result == FR_OK ? buf : NULL; }

__fs = new FATFS_VFS("/spiflash", "storage");

It looks like FTPServer class do not have method to set root directory such as /spiflash or /sdcard.

Have some one test FTPServer class with spi flash or sd card.

The FTPServer class is quite new in this repository. So, I am not sure if ever someone used this class except Mr. Kolban. Unfortunately I currently do not have the time to work on my ESP32 project - otherwise we could try to get things working together as it seems that we have quite similar targets. My project finally also should use HttpServer with SSL serving a bigger size web page from an SD card. The web page will be made using a higher level Javascript framework and an FTP Server for updating this website. Later on I also would like to add MQTT protocol.

Have you tried HttpServer with SSL enabled yet?

[squonk11]

no, also this I did not try until now. I am quite in the beginning of my project and I don't know if will ever be able to finish it. Until now I just tested HttpServer and mongoose server to serve a smaller web page. This works so far. I decided to stay with HttpServer as it is free SW because if I finish the project it might become a comercial thing. Maybe in a few weeks I will have time again to continue on this project.

[snahmad]

ok. let me know outcome

o.k.

I have tried to use this FTP code as well, but I keep getting the same "undefined reference to getcwd" errors during the linking stage of the build. There must be some problems with the #include line at the top of the code, but I can't seem to figure out what exactly. I'll post if I find a fix.
