java实现homeassistant api控制开关

可以使用Java的HTTP请求库,向HomeAssistant的API发送控制开关的请求。具体实现可以参考HomeAssistant的API文档和Java的HTTP请求库的使用方法。以下是一个简单的示例代码:
```
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class HomeAssistantAPI {
public static void main(String[] args) {
String url = "http://your-homeassistant-ip:8123/api/services/switch/turn_on";
String data = "{\"entity_id\": \"switch.your_switch_entity_id\"}";
try {
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
// add request header
con.setRequestMethod("POST");
con.setRequestProperty("Content-Type", "application/json");
con.setRequestProperty("Authorization", "Bearer your_access_token");
// send post request
con.setDoOutput(true);
OutputStreamWriter out = new OutputStreamWriter(con.getOutputStream());
out.write(data);
out.flush();
out.close();
int responseCode = con.getResponseCode();
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
// print result
System.out.println(response.toString());
} catch (Exception e) {
e.printStackTrace();
}
}
}
```
其中,`url`是HomeAssistant的API地址,`data`是控制开关的请求数据,`Authorization`是访问HomeAssistant API的access token。需要注意的是,`switch.your_switch_entity_id`需要替换成你要控制的开关的实体ID。
