帮我修正以下代码:#include <SoftwareSerial.h> SoftwareSerial espSerial(1, 0); // 设置ESP8266的RX和TX引脚 // LED引脚 const int redLED = 4; const int yellowLED = 5; const int blueLED = 6; void setup() { Serial.begin(9600); // 与电脑串口通信 espSerial.begin(115200); // 与ESP8266通信 // 初始化ESP8266 sendCommand("AT+RST"); // 重启ESP8266 delay(2000); // 等待ESP8266重启完毕 // 连接WiFi网络 sendCommand("AT+CWJAP=\"123\",\"aaalcc16\""); // 替换为你的WiFi网络的SSID和密码 delay(5000); // 等待ESP8266连接到WiFi网络 } void loop() { // 发送HTTP请求获取天气数据 sendCommand("AT+CIPSTART=\"TCP\",\"api.seniverse.com\",80"); delay(2000); // 构建HTTP请求 String getRequest = "GET /v3/weather/now.json?key=S-l4ShgyRNWTaQJ3a&location=guangzhou HTTP/1.1\r\nHost:api.seniverse.com\r\nConnection: close\r\n\r\n"; String cmd = "AT+CIPSEND="; cmd += getRequest.length(); sendCommand(cmd); delay(1000); sendCommand(getRequest); delay(5000); // 等待服务器响应 // 获取天气信息 const char* text = doc["results"][0]["now"]["text"]; // 根据天气信息控制LED if (strcmp(text, "晴") == 0) { digitalWrite(redLED, HIGH); digitalWrite(yellowLED, HIGH); digitalWrite(blueLED, LOW); } else if (strcmp(text, "雨") == 0) { digitalWrite(redLED, LOW); digitalWrite(yellowLED, LOW); digitalWrite(blueLED, HIGH); } else { digitalWrite(redLED, LOW); digitalWrite(yellowLED, LOW); digitalWrite(blueLED, LOW); } delay(60000); // 每隔60秒获取一次天气数据 } void sendCommand(String cmd) { espSerial.println(cmd); while (!espSerial.available()); while (espSerial.available()) { Serial.write(espSerial.read()); } }

在代码中,获取天气信息的部分缺少了JSON解析的代码。你需要引入ArduinoJson库并添加相应的代码来解析JSON格式的天气数据。以下是修正后的代码:
```
#include <SoftwareSerial.h>
#include <ArduinoJson.h>
SoftwareSerial espSerial(1, 0); // 设置ESP8266的RX和TX引脚
// LED引脚
const int redLED = 4;
const int yellowLED = 5;
const int blueLED = 6;
void setup() {
Serial.begin(9600); // 与电脑串口通信
espSerial.begin(115200); // 与ESP8266通信
// 初始化ESP8266
sendCommand("AT+RST"); // 重启ESP8266
delay(2000); // 等待ESP8266重启完毕
// 连接WiFi网络
sendCommand("AT+CWJAP=\"123\",\"aaalcc16\""); // 替换为你的WiFi网络的SSID和密码
delay(5000); // 等待ESP8266连接到WiFi网络
}
void loop() {
// 发送HTTP请求获取天气数据
sendCommand("AT+CIPSTART=\"TCP\",\"api.seniverse.com\",80");
delay(2000);
// 构建HTTP请求
String getRequest = "GET /v3/weather/now.json?key=S-l4ShgyRNWTaQJ3a&location=guangzhou HTTP/1.1\r\nHost:api.seniverse.com\r\nConnection: close\r\n\r\n";
String cmd = "AT+CIPSEND=";
cmd += getRequest.length();
sendCommand(cmd);
delay(1000);
sendCommand(getRequest);
delay(5000); // 等待服务器响应
// 解析JSON格式的天气数据
String response = "";
while (espSerial.available()) {
char c = espSerial.read();
response += c;
}
StaticJsonDocument<512> doc;
deserializeJson(doc, response);
const char* text = doc["results"][0]["now"]["text"];
// 根据天气信息控制LED
if (strcmp(text, "晴") == 0) {
digitalWrite(redLED, HIGH);
digitalWrite(yellowLED, HIGH);
digitalWrite(blueLED, LOW);
} else if (strcmp(text, "雨") == 0) {
digitalWrite(redLED, LOW);
digitalWrite(yellowLED, LOW);
digitalWrite(blueLED, HIGH);
} else {
digitalWrite(redLED, LOW);
digitalWrite(yellowLED, LOW);
digitalWrite(blueLED, LOW);
}
delay(60000); // 每隔60秒获取一次天气数据
}
void sendCommand(String cmd) {
espSerial.println(cmd);
while (!espSerial.available());
while (espSerial.available()) {
Serial.write(espSerial.read());
}
}
```
需要注意的是,以上代码中的JSON解析部分使用了ArduinoJson库的StaticJsonDocument类,需要在代码的顶部添加以下代码引入ArduinoJson库:
```
#include <ArduinoJson.h>
```
