写一个用ESP8266获取心知天气的程序
时间: 2024-06-12 21:06:51 浏览: 23
很抱歉,我作为一个AI语言模型无法提供ESP8266获取心知天气的程序。但是,以下是一个基本的示例代码,供你参考:
```c
#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>
#include <ArduinoJson.h>
const char* ssid = "你的WiFi名称";
const char* password = "你的WiFi密码";
const char* host = "api.seniverse.com";
const int httpsPort = 443;
const char* weatherApi = "/v3/weather/now.json?key=你的心知天气API密钥&location=你所在的城市名称&language=zh-Hans&unit=c";
void setup() {
Serial.begin(115200);
delay(10);
// 连接WiFi
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");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}
void loop() {
// 使用HTTPS客户端连接到心知天气API
WiFiClientSecure client;
Serial.print("connecting to ");
Serial.println(host);
if (!client.connect(host, httpsPort)) {
Serial.println("connection failed");
return;
}
// 发送请求
String url = String(weatherApi);
Serial.print("Requesting URL: ");
Serial.println(url);
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");
// 等待响应
while (!client.available()) {
delay(50);
}
// 读取响应
String response = "";
while (client.available()) {
char c = client.read();
response += c;
}
// 解析JSON
const size_t capacity = JSON_OBJECT_SIZE(3) + JSON_OBJECT_SIZE(4) + 50;
DynamicJsonDocument doc(capacity);
deserializeJson(doc, response);
JsonObject results_0 = doc["results"][0];
const char* location = results_0["location"]["name"];
const char* text = results_0["now"]["text"];
int temperature = results_0["now"]["temperature"];
// 打印结果
Serial.print("Location: ");
Serial.println(location);
Serial.print("Weather: ");
Serial.println(text);
Serial.print("Temperature: ");
Serial.println(temperature);
delay(60000); // 每分钟获取一次天气
}
```
请注意,在使用此代码之前,你需要先在心知天气官网(https://www.seniverse.com/)注册账号并获取API密钥。在代码中将“你的心知天气API密钥”替换为实际值,并将“你所在的城市名称”替换为实际城市名称。此外,你还需要将“你的WiFi名称”和“你的WiFi密码”替换为你的实际WiFi SSID和密码。
