#31294
Whiddled it down to the following code.
Any help is appreciated.
Don't exactly get whats going on.
Code: Select all#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
#include "spiffs/spiffs.h"
#include <FS.h>
const char* ssid = "........";
const char* password = "........";
ESP8266WebServer server(80);
const char* serverIndex = "<form method='POST' action='/update' enctype='multipart/form-data'><input type='file' name='update'><input type='submit' value='Update'></form>";
void setup(void)
{
SPIFFS.begin();
Serial.begin(9600);
WiFi.mode(WIFI_AP_STA);
WiFi.begin(ssid, password);
if (WiFi.waitForConnectResult() == WL_CONNECTED)
{
server.on("/", HTTP_GET, []() {
server.sendHeader("Connection", "close");
server.sendHeader("Access-Control-Allow-Origin", "*");
server.send(200, "text/html", serverIndex);
});
server.onFileUpload([]() {
//if (server.uri() != "/update") return;
HTTPUpload& upload = server.upload();
String Test = upload.filename.c_str();
File f = SPIFFS.open(String("/" + Test ), "w");
f.print(upload.buf);
f.close();
yield();
});
server.on("/update", HTTP_POST, []() {
server.sendHeader("Connection", "close");
server.sendHeader("Access-Control-Allow-Origin", "*");
server.send(200, "text/plain", "OK");
ESP.restart();
});
server.begin();
}
}
void loop(void) {
server.handleClient();
delay(0);
} I get the following error msg.
