你能写一段esp8266获取心知天气的代码吗

当然可以，以下是一个简单的示例代码：

#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>
#include <ArduinoJson.h>

const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
const char* host = "api.seniverse.com";
const String location = "your_location"; // 例如："beijing" 或 "ip"
const String apiKey = "your_API_KEY";

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");
}

void loop() {
  WiFiClientSecure client;
  if (!client.connect(host, 443)) {
    Serial.println("Connection failed");
    return;
  }
  String url = "/v3/weather/now.json?key=" + apiKey + "&location=" + location;
  client.print(String("GET ") + url + " HTTP/1.1\r\n" +
               "Host: " + host + "\r\n" +
               "User-Agent: ESP8266\r\n" +
               "Connection: close\r\n\r\n");
  while (!client.available()) {
    delay(100);
  }
  String response = client.readString();
  Serial.println(response);
  const size_t capacity = JSON_OBJECT_SIZE(1) + JSON_OBJECT_SIZE(2) + JSON_OBJECT_SIZE(3) + JSON_OBJECT_SIZE(4) + JSON_OBJECT_SIZE(5) + JSON_OBJECT_SIZE(6) + JSON_OBJECT_SIZE(7) + 260;
  DynamicJsonDocument doc(capacity);
  deserializeJson(doc, response);
  JsonObject results = doc["results"][0];
  JsonObject now = results["now"];
  String text = now["text"];
  int temperature = now["temperature"];
  Serial.print("天气：");
  Serial.print(text);
  Serial.print("，温度：");
  Serial.print(temperature);
  Serial.println("℃");
  delay(60000); // Wait for 1 minute before checking again
}

该代码使用 ESP8266 连接到心知天气 API，获取指定位置的天气信息，并将天气状况和温度打印到串口监视器中。你需要替换 `your_SSID`、`your_PASSWORD` 和 `your_API_KEY` 为你的 WiFi 名称、密码和心知天气 API 密钥。同时你可以修改 `location` 变量以获取其他位置的天气信息。
