 Ich möchte einen Webserver mit ESP32 eröffnen

Post by Anonymous »

Ich bin nicht gut in Englisch, deshalb habe ich einen Übersetzer verwendet.
Vielen Dank
Bitte haben Sie Verständnis dafür, dass wir nicht den gesamten Code anzeigen können.
Derzeit versuche ich, den AP-Modus in ESP32 zu öffnen und HTML-Informationen an die verbundene Person zu senden.
Ich versuche jedoch, chart.min.js oder chart.min.js.gz zu senden.
Die Die Anfrage wurde eindeutig von esp32 empfangen.
Ich kann Ihnen keine Daten senden.
Was soll ich tun?
