ESP8266 Code to list SPIFFS Files as URL on web --Solved
Posted: Wed Mar 06, 2019 9:02 pmmartinayotte coded a helper to list SPIFFS files on a web page; very quick and does a great job.
Moving on to the ESP32; requesting help converting code from ESP8266 to the newer ESP32 SPIFFS directory structure. Found a function to list directories; do not understand how to use martinayotte's helper with this function.
ESP32 funtion:

Tried using the helper with the ESP32 function unsuccessfully.

Moving on to the ESP32; requesting help converting code from ESP8266 to the newer ESP32 SPIFFS directory structure. Found a function to list directories; do not understand how to use martinayotte's helper with this function.
ESP32 funtion:
Code: Select all
https://github.com/espressif/arduino-esp32/blob/master/libraries/SPIFFS/examples/SPIFFS_Test/SPIFFS_Test.ino
#include "FS.h"
#include "SPIFFS.h"
/* You only need to format SPIFFS the first time you run a
test or else use the SPIFFS plugin to create a partition
https://github.com/me-no-dev/arduino-esp32fs-plugin */
#define FORMAT_SPIFFS_IF_FAILED true
void listDir(fs::FS &fs, const char * dirname, uint8_t levels){
Serial.printf("Listing directory: %s\r\n", dirname);
File root = fs.open(dirname);
if(!root){
Serial.println("- failed to open directory");
return;
}
if(!root.isDirectory()){
Serial.println(" - not a directory");
return;
}
File file = root.openNextFile();
while(file){
if(file.isDirectory()){
Serial.print(" DIR : ");
Serial.println(file.name());
if(levels){
listDir(fs, file.name(), levels -1);
}
} else {
Serial.print(" FILE: ");
Serial.print(file.name());
Serial.print("\tSIZE: ");
Serial.println(file.size());
}
file = root.openNextFile();
}
}
ESP8266 code use to list SPIFFS as filename URL links:
Code: Select all
// Check the action to see if it was a GET request.
else if (strcmp(path, "/SdBrowse") == 0) // Respond with the path that was accessed.
{
// send a standard http response header
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println();
client.println("<!DOCTYPE HTML>");
client.println("<html>");
client.println("<body>");
client.println("<head><title>SDBrowse</title><head />");
// print all the files, use a helper to keep it clean
client.println("<h2>Collected Observations</h2>");
//////////////// Code to listFiles from martinayotte of the "ESP8266 Community Forum" ///////////////
String str = String("<html><head></head>");
if (!SPIFFS.begin())
{
Serial.println("SPIFFS failed to mount !");
}
Dir dir = SPIFFS.openDir("/");
delay(20);
while (dir.next())
{
str += "<a href=\"";
str += dir.fileName();
str += "\">";
str += dir.fileName();
str += "</a>";
str += " ";
str += dir.fileSize();
str += "<br>\r\n";
}
client.print(str);
////////////////// End code by martinayotte //////////////////////////////////////////////////////
client.println("<br><br>");
client.println("<a href=http://" + publicIP + ":" + LISTEN_PORT + "/Weather >Current Observations</a><br>");
client.println("</body></html>\r\n");
end();
} Tried using the helper with the ESP32 function unsuccessfully.
