Nest change target_temperature_f：如何使用java http PUT通过android代码设置Nest Thermostat的目标温度？

Answer 1

您可以使用HttpClient或HttpURLConnection从Android调用其余API上的PUT。以下是使用HttpURLConnection的示例。

注意：建议您缓存每个用户/访问令牌的重定向URL，并将其重新用于该用户的所有后续调用。

这里假设开头的基础是https://developer-api.nest.com/

如果来自urlconnection的返回码是307（重定向），则缓存该位置并将其用于发出放置请求。（注意这里的缓存表示某种全局缓存/ concurrentMap）

public static int setThermostatTemperatureF(int temperatureF,
    String base, String thermostatId, String accessToken) throws IOException {
try {
    String tChangeUrl = String.format("%s/devices/thermostats/%s/target_temperature_f?auth=%s",
            base, thermostatId, accessToken);
    URL url = new URL(tChangeUrl);
    HttpsURLConnection ucon = (HttpsURLConnection) url.openConnection();
    ucon.setRequestProperty("Content-Type", "application/json");
    ucon.setRequestMethod("PUT");
    ucon.setDoOutput(true);
    // Write the PUT body
    OutputStreamWriter writer = new OutputStreamWriter(ucon.getOutputStream());
    writer.append(Integer.toString(temperatureF));
    writer.flush();

    int responseCode = ucon.getResponseCode();
    if (responseCode == 307) { // temporary redirect
        // cache the URL for future uses for this User
        String redirectURL = ucon.getHeaderField("Location");
        URI u = new URI(redirectURL);
        StringBuilder baseUrl = new StringBuilder(u.getScheme())
                .append("://").append(u.getHost());
        if (u.getPort() != 0) {
            baseUrl.append(":").append(u.getPort());
        }
        baseUrl.append("/");
        cache.put(accessToken, baseUrl.toString());
        return setThermostatTemperatureF(temperatureF, baseUrl.toString(), thermostatId, accessToken);
    } else {
        return responseCode;
    }
} catch (MalformedURLException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
} catch (URISyntaxException e) {
    e.printStackTrace();
}
return -1;

}
