【中文标题】请求 HttpResponse<JsonNode> 时 Android 应用程序崩溃

【英文标题】：Android App crashes when requesting HttpResponse<JsonNode>

【问题描述】：

我目前正在使用 FAROO Web Search 开发一个新闻应用程序，但是当应用程序使用 API 代码查找新闻时，它会崩溃。我不认为这是 API 的错，因为在 RapidApi 的测试中它工作得很好。我已经在 android Manifest 中添加了互联网权限，并且一直在稳定连接使用它。 [![API 测试][1]][1] 如图所示，在网络中测试端点时，它可以毫无问题地获得结果。

我还尝试添加“implementation 'org.apache.httpcomponents:httpclient:4.5'”，甚至排除一些文件，因为它们会产生更多错误。

这是主要活动

static final ArrayList<String> title_array = new ArrayList<String>();
static final ArrayList<String> notice_array = new ArrayList<String>();
static final ArrayList<String> author_array = new ArrayList<String>();
ListView list;
BaseAdapter2 adapter;
ProgressBar loader;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) 
    System.out.println("Enter");
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_news_activity);
    list = (ListView) findViewById(R.id.listNews);
    loader = (ProgressBar) findViewById(R.id.loader);
    if(InternetAvaliable(this))
    new TheTask().execute();




class TheTask extends AsyncTask<Void, Void, String> 

    @Override
    protected String doInBackground(Void... params) 
        String str = null;

        try 
            System.out.println("Here1");

                HttpResponse<JsonNode> response = Unirest.get("https://faroo-faroo-web-search.p.rapidapi.com/api?q=food")
                        .header("X-RapidAPI-Host", "faroo-faroo-web-search.p.rapidapi.com")
                        .header("X-RapidAPI-Key", "f18432002emshe33f07d9b71559bp125dd7jsn2d9f1840345f")
                        .asJson();

                System.out.println("Here2");
                str = response.toString();

        
        catch(UnirestException exception)exception.printStackTrace();

        return str;
    


    @Override
    protected void onPostExecute(String result) 
        super.onPostExecute(result);

        String response = result.toString();

        try

            JSONArray new_array = new JSONArray(response);

            for(int i = 0; i < new_array.length(); i++)

                try
                JSONObject jsonObject = new_array.getJSONObject(i);
                if(jsonObject.getBoolean("news")) 
                    title_array.add(jsonObject.getString("title").toString());
                    notice_array.add(jsonObject.getString("kwic").toString());
                    author_array.add(jsonObject.getString("author").toString());
                
                catch (JSONException e)e.printStackTrace();

            

            adapter = new BaseAdapter2(NewsActivity.this, title_array, notice_array, author_array);
            list.setAdapter(adapter);


         catch (JSONException e)e.printStackTrace();
    

错误就在这里

【问题讨论】：

如果您按照here 的解释useLibrary 'org.apache.http.legacy' 会发生什么？

它给出了这个错误：E/AndroidRuntime: FATAL EXCEPTION: AsyncTask #1 Process: com.example.ecoapp, PID: 16335 java.lang.RuntimeException: An error occurred while executing doInBackground() at android.os.AsyncTask$3.done(AsyncTask.java:353) at java.util.concurrent.FutureTask.finishCompletion(FutureTask.java:383) Caused by: java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/http/client/config/RequestConfig;

【参考方案1】：

用okhttp请求试试

下面是请求

OkHttpClient client = new OkHttpClient();

Request request = new Request.Builder()
  .url("https://faroo-faroo-web-search.p.rapidapi.com/api?q=food")
  .get()
  .addHeader("x-rapidapi-host", "faroo-faroo-web-search.p.rapidapi.com")
  .addHeader("x-rapidapi-key", "f18432002emshe33f07d9b71559bp125dd7jsn2d9f1840345f")
  .addHeader("cache-control", "no-cache")
  .addHeader("postman-token", "896be9fc-b0c5-e8eb-5f75-df68fcefab84")
  .build();

Response response = client.newCall(request).execute();

然后像这样得到身体响应

String response =response.body.string()

我希望这会有所帮助，不要忘记添加 okhttp 依赖项
