Messaging API作為替代方案

LINE超好用功能要沒了！LINE Notify明年3月底終止服務，有什麼替代方案？

LINE Notify將於2025年3月31日結束服務，官方建議改用Messaging API作為替代方案。

//CHANNEL_ACCESS_TOKEN = 'Messaging API Token';

CHANNEL_ACCESS_TOKEN = 'E2ElxCQeoDszSHF0N1TJsyytnnae+HF1XZ733YVYj1RQcpjAT1oi2Fa2TScNbOz+q815fFVp4MuFW+UC4PsfKbvtc/o0OM6hchpxuQURZyvizGq+/cAz/TgCwJ9wQ4ebkQyEXEDzaYUZ/Dx3yaaBgwdB04t89/1O/w1cDnyilFU=';

USER_ID = 'Ua2f646d82a75d31dee884a6fdfa95f76'; //'使用者ID(不是Line ID)';

message = {

type:'text',

text:'目前日圓匯率：'+msg.payload.jpy

};

headers = {

'Content-Type': 'application/json; charset=UTF-8',

'Authorization': 'Bearer ' + CHANNEL_ACCESS_TOKEN,

};

payload = {

ESP32 與 MFRC522連接方式 (硬體連接)

GND = GND 3.3V = 3.3V

The following table shows the typical pin layout used:

* MFRC522 ESP32

* Reader/PCD

* Signal Pin Pin

* RST/Reset RST GPIO27

* SPI SS SDA(SS) GPIO5

* SPI MOSI MOSI GPIO23

* SPI MISO MISO GPIO19

* SPI SCK SCK GPIO18

[1] (1, 2) Configurable, typically defined as RST_PIN in sketch/program.

[2] (1, 2) Configurable, typically defined as SS_PIN in sketch/program.

[3] The SDA pin might be labeled SS on some/older MFRC522 boards
