Json 400错误-给定位置无效

我试图通过API检索JSON数据，并将其解析到我的Android中。我正在尝试记录检索到的JSON数据，但我一直收到一个“400错误-给定位置无效”。访问API的参数似乎正确，但我不确定为什么无法检索数据

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    temperatureLabel = (TextView) findViewById(R.id.temperatureLabel);
    timeLabel = (TextView) findViewById(R.id.timeLabel);
    refreshButton = (ImageView) findViewById(R.id.refreshImage);

    final double latitude = -104.8319;
    final double longtitude = 39.7294;

    refreshButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            getWeatherForecast(latitude, longtitude);
        }
    });

    getWeatherForecast(latitude, longtitude);
}

    public void getWeatherForecast(double latitude, double longtitude) {

    String apiKey = "SECRET-KEY;
    String forecastURL = "https://api.darksky.net/forecast/" + apiKey + "/" + latitude + ","
            + longtitude;

    if (isNetworkAvailable()) {

        //Build and HTTP request
        OkHttpClient client = new OkHttpClient();
        Request request = new Request.Builder().url(forecastURL).build();

        //Make an Api call
        Call call = client.newCall(request);
        call.enqueue(new Callback() {
            @Override
            public void onFailure(Request request, IOException e) {

                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        alertUserError();
                    }
                });
            }
            @Override
            public void onResponse(Response response) throws IOException {
            try {

                String jsonData = response.body().string();
                Log.e(TAG, "JASON DATA" + jsonData);

                if (response.isSuccessful()) {
                    mcurrentWeather = getCurrentWeatherDetails(jsonData);
                    // You want to update the display In the UI.
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            updateDisplay();
                        }
                    });
                } else {
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            Toast.makeText(getApplicationContext(), "API call failed", Toast.LENGTH_LONG).show();
                        }
                    });
                }
            } catch (IOException e) {
               Log.e(TAG, "Exception Caught");
            } catch (JSONException e) {
               Log.e(TAG, "JSONexception Caught");
            }
        }
    });
} else {
    alertUserError();
    }
}

如果您试图检查发送给

API

的请求以及

API

发送给您的请求，那么您应该执行。使用它既简单又容易。

首先，我已从您的答案中删除了您的密钥，并将其替换为“secret-key”。DarkSky每天只有1000个请求是免费的，所以有人可以抓取密钥并重用它。你得付钱

我想去重置密钥以避免风险

第二，坐标交换。你现在有

final double latitude = -104.8319;
final double longtitude = 39.7294;
String forecastURL = "https://api.darksky.net/forecast/" + apiKey + "/" 
        + latitude + ","
        + longtitude;

这一结果是：

然后是“400，位置无效”，因为世界上没有纬度为-104、经度为39的位置

正确的答案是

final double latitude = 39.7294;
final double longtitude = -104.8319;

那么您的

urlString

是：

浏览器中的哪些输出：

{
"latitude":39.7294,
"longitude":-104.8319,
"timezone":"America/Denver",
"currently":{
    "time":1583068320,
    "summary":"Mostly Cloudy",
    "icon":"partly-cloudy-night",
    "nearestStormDistance":9,
    "nearestStormBearing":145,
    "precipIntensity":0,
    "precipProbability":0,
    "temperature":37.32,
    "apparentTemperature":33.14,
    "dewPoint":18.62,
    "humidity":0.46,
    "pressure":1011.5,
    "windSpeed":5.24,
    "windGust":7.61,
    "windBearing":157,
    "cloudCover":0.87,
    "uvIndex":0,
    "visibility":10,
    "ozone":309},
"offset":-7
}

注意，我包含了
