我一直在 android 工作室制作新聞 API 項目，但 volley 出現錯誤。 錯誤 - com.android.volley.AuthFailureError。 使用 json

Question

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        RequestQueue requestQueue;
        requestQueue = Volley.newRequestQueue(this);
        List<news_Objects> newsList = new ArrayList<>();
 
        //url for News API 

        String url="https://newsapi.org/v2/everything?q=apple&from=2021-08-31&to=2021-08-31&sortBy=popularity&apiKey=ca3d6c89eff24db2a8ef78868f0af555";

//making json object request
        JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {

                try {
                    JSONArray jsonArr = response.getJSONArray("articles");

                    for (int i = 0; i < jsonArr.length(); i++) {
                        JSONObject newsDetail = jsonArr.getJSONObject(i);

//class name news_Objects created 

                        news_Objects news = new news_Objects();

                        String imtUrl = newsDetail.getString("urlToImage");
                        String title = newsDetail.getString("title");
                        String detail = newsDetail.getString("description");
                        String newsUrl = newsDetail.getString("url");
                        String content = newsDetail.getString("content");

                        news.setNewsImageUrl(imtUrl);
                        news.setNewsTitle(title);
                        news.setNewsDetail(detail);
                        news.setNewsUrl(newsUrl);
                        news.setContent(content);
                        newsList.add(news);
                    }

                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Log.d("fine", "Something Wrong"+error);
                Toast.makeText(MainActivity.this, "Something Wrong "+error, Toast.LENGTH_SHORT).show();
                error.printStackTrace();
            }
        });
        requestQueue.add(request);

    }
}

Answer 1

您的 API 密鑰無效，請檢查您的 API 密鑰。 得到這個響應：{"status":"error","code":"apiKeyInvalid","message":"Your API key is invalid or incorrect. Check your key, or go to https://newsapi.org to create免費的 API 密鑰。”}

Answer 2

也許您的 API 密鑰未激活，請檢查您的 API 密鑰狀態，然后再次點擊 api。
