我目前正在使用 FAROO Web Search 开发新闻应用程序，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 test][1]][1] 如图所示，在 Web 中测试端点时，它可以毫无问题地获得结果。

我还尝试添加“实现 'org.apache.httpcomponents:httpclient:4.5'”，甚至排除某些文件，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

尝试使用 okhttp 请求

以下是请求

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();

然后得到身体的反应，比如

String response =response.body.string()

我希望这会有所帮助，不要忘记添加 okhttp 依赖项
