致命异常：确定Http调度程序

android java okhttp

我正在我的Android应用程序中使用OkHttp库向天气API发出Web请求。我已经实现了我的代码，并且在执行请求时收到致命异常。

我也已经在我的清单中添加了 INTERNET 权限。

主要活动.java：

private CurrentWeather currentWeather;

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        final ActivityMainBinding binding = DataBindingUtil.setContentView(MainActivity.this, R.layout.activity_main);

        String apiKey = "xxx";
        double latitude = 37.8267;
        double longitude = -122.4233;
        String forecastURL = String.format("https://api.darksky.net/forecast/%s/%f,%f", apiKey, latitude, longitude);

        if (isNetworkAvailable()) {
            OkHttpClient client = new OkHttpClient();

            Request request = new Request.Builder()
                    .url(forecastURL)
                    .build();

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

                }

                @Override
                public void onResponse(Call call, Response response) throws IOException {
                    try {
                        Log.v(TAG, response.body().string());
                        String jsonData = response.body().string();
                        if (response.isSuccessful()) {
                            currentWeather = getCurrentDetails(jsonData);
                        }

                    } catch (IOException e) {
                        Log.e(TAG, e.getLocalizedMessage());
                    } catch (JSONException e) {
                        Log.e(TAG, e.getLocalizedMessage());
                    }
                }
            });
        }
        Log.d(TAG, "Main UI code is running");
    }

    private CurrentWeather getCurrentDetails(String jsonData) throws JSONException {

        JSONObject forecast = new JSONObject(jsonData);
        String timezone = forecast.getString("timezone");

        JSONObject currently = forecast.getJSONObject("currently");

        String icon = currently.getString("icon");
        String locationLabel = "Alcatraz Island";
        String summary = currently.getString("summary");
        long time = currently.getLong("time");
        double humidity = currently.getDouble("humidity");
        double precipProbability = currently.getDouble("precipProbability");
        double temperature = currently.getDouble("temperature");

        return new CurrentWeather(locationLabel, icon, time, temperature, humidity, precipProbability, summary, timezone);
    }

等级：

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.squareup.okhttp3:okhttp:3.12.0'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

然后，这是我得到的例外：

2018-12-04 20:55:49.969 3314-3330/com.test.starmie E/AndroidRuntime: FATAL EXCEPTION: OkHttp Dispatcher

        at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:607)
        at java.lang.Thread.run(Thread.java:761)

我不知道在这一点上该怎么办。我已经阅读了一下，并找到了一些关于这个主题的帖子。根据我收集到的信息，必须在 runOnUiThread（）块中对 UI 进行更改。但是我没有在我的代码中进行任何UI更改，我仍然得到异常。

我也已经尝试过将我的JSON解析代码放在runOnUiThread（）中，并得到了相同的致命异常结果。有人有什么想法吗？

答案 1

Response身体只能食用一次。你做了两次

Log.v(TAG, response.body().string());
String jsonData = response.body().string();

答案 2

这是由于使用不同版本的 OkHttp 引起的。确保 com.squareup.okhttp3 中的所有依赖项都使用相同的版本。

例：

implementation 'com.squareup.okhttp3:logging-interceptor:3.8.0'
implementation 'com.squareup.okhttp3:okhttp:3.8.0'
