Android 获取数据-如何？

我正在尝试根据设备坐标从api获取数据。 我正在通过模拟器中的外部控件传递纬度和经度。我正在尝试根据用户的输入显示属性详细信息。提前感谢您的帮助。 但是我得到的是状态代码

403

错误消息：

Failcz.msebera.android.httpclient.client.HttpResponseException： 禁止的

代码如下：

public class WeatherController extends AppCompatActivity {

    final long MIN_TIME = 5000;
    // Distance between location updates (1000m or 1km)

根据，您需要将API密钥作为头发送。我在你的代码中没有看到这一点。我猜这就是服务器拒绝您的请求的原因。

您的“if（grantResults.length>0&&…”行后面是否应该有一个分号？我想这表示，“if grantResults.length>0&&…什么都不做。现在，始终调用getWeatherForCurrentLocation（），即使grantResults.length为0。您可能应该考虑添加{}”或者至少去掉if语句的分号。仍然得到相同的错误，但谢谢。请告诉我如何将其作为标头传递？我不熟悉AsyncHttpClient库，但似乎您可以只执行

client。addHeader（key，value）

解决了它，感谢您为我指明了正确的方向
