烦了，封装起来用来copy

快速上手

#include <ESP8266WiFi.h>
#include <ESP8266WiFiMulti.h>

ESP8266WiFiMulti wifiMulti;    

void wifiInit()
  wifiMulti.addAP("LAPTOP9#337", "xy1229033519");
  wifiMulti.addAP("MI 9", "12345678"); 
  wifiMulti.addAP("ssid_from_AP_3", "your_password_for_AP_3"); 
  Serial.println("Connecting ...");                            
  
  int i = 0;                                 
  while (wifiMulti.run() != WL_CONNECTED) 
    delay(1000); 
    Serial.print(i++); Serial.print(' '); 
     

  Serial.println('\\n');
  Serial.print("Connected to ");
  Serial.println(WiFi.SSID());
  Serial.print("IP address:\\t");
  Serial.println(WiFi.localIP());


void setup()
	Serial.begin(9600);
	wifiInit();
