java - Nest 恒温器 API : Connection time out after establishing a request using the retrieved access_token

Question

我正在制作一个 Android 应用程序，使用新发布的 API 与恒温器 NEST 通信。我正在按照此页面中提供的说明进行操作:https://developer.nest.com/documentation/how-to-auth .

我已经让它运行到我成功收到 access_token 的地步。但是使用该 access_token 并建立对 https://developer-api.nest.com/devices.json?auth= 的 HTTP GET 请求{access_token} 我收到连接超时异常!

@mccv 这是我的代码:

private void make_REST_call(String access_token) {

    String access_token_uri = "https://developer-api.nest.com/devices.json?auth="+access_token;

    try {
        URI uri = new URI(access_token_uri);

        // Set the connection timeout value to X seconds (30000 milliseconds)
        final HttpParams httpParams = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(httpParams, 100000);  // In miliseconds
        httpclient = new DefaultHttpClient(httpParams);
        HttpGet httpget = new HttpGet();
        httpget.setURI(new URI(access_token_uri));

        // Execute HTTPs GET request
        Long reqTime = System.currentTimeMillis();
        Log.d(tag + " make_REST_call", " reqTime time= " + reqTime);

        HttpResponse response = null;

        try {
            response = httpclient.execute(httpget);
            Log.d(tag + " make_REST_call", " response is= " + response.getEntity());
        }
        catch (Exception e) {
            e.printStackTrace();
            Log.e(tag + " make_REST_call", e.toString());
        }

        Long resTime = System.currentTimeMillis();
        Log.d(tag + " make_REST_call", " response time= " + (resTime - reqTime));

    }
    catch (Exception e) {
        Log.e(access_token_uri, e.toString());
        e.printStackTrace();
    }
}

我想出了问题所在。

实际上在我访问端口被阻止的服务器的路上有防火墙。通过将我的 httpclient 重定向到代理，我绕过了它，所以问题就解决了。
