Question

我正在尝试通过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，但我一直收到错误 - 给定位置无效。＆＃34;访问API的参数似乎是正确的，但我不确定为什么我无法检索数据。

    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 = "2e31c60ad62bae1a7bba53403d1a5a40";
    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();
    }
}

在这里输入代码

Answer 1

如果您要检查发送给API的请求以及API发送给您的请求，那么您应该实施OkHttp logging interceptor。使用它简单易行。

Answer 2

首先，我从答案中删除了您的秘密密钥，并将其替换为“ SECRET-KEY”。 DarkSky每天只有1000个免费请求，因此有人可以抓住该密钥并重新使用它。您必须为此付费。

我会去https://darksky.net/dev/account并重置密钥以避免风险。

第二，将交换您的坐标。您当前有

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

以下结果：

https://api.darksky.net/forecast/SECRET-KEY/-104.8319,39.7294?exclude=minutely,hourly,daily,flags,alerts

则为“ 400，位置无效”，因为世界上没有位置为-104，经度为39。

正确的是

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

那么您的urlString是：

https://api.darksky.net/forecast/SECRET-KEY/39.7294,-104.8319?exclude=minutely,hourly,daily,flags,alerts

在浏览器中输出的

{
"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
}

P.S：注意，我添加了exclude查询项以缩短响应以显示示例。删除该部分，您将获得所有响应，包括分钟，每天等等。
