为ESP8266写一段联网程序

#include <ESP8266WiFi.h>

void setup() {
Serial.begin(115200);
// Connect to a WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);

WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}

Serial.println("");
Serial.println("WiFi connected");

// Print the IP address
Serial.println(WiFi.localIP());
}

void loop() {
// put your main code here, to run repeatedly:
}
