使用 volley 库获取 json 方法的错误 com.android.volley.AuthFailureError

如何解决使用 volley 库获取 json 方法的错误 com.android.volley.AuthFailureError

我试图从新闻 API 获取新闻，但是当我请求它时，它给了我错误 com.android.volley.AuthFalureError。我也尝试从不同的 mailId 更改 API 密钥，但仍然遇到相同的错误

class InApp : AppCompatActivity(),NewsItemClicked {

    private lateinit var mAdapter: InAppAdapter
    lateinit var inAppRecyclerView: RecyclerView
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_in_app)

        inAppRecyclerView=findViewById(R.id.inappRecyclerView)
        inAppRecyclerView.layoutManager=GridLayoutManager(this,1)
        fetchData()
        mAdapter = InAppAdapter(this)
        inAppRecyclerView.adapter = mAdapter

    }


    private fun fetchData() {
        val url ="https://newsapi.org/v2/everything?q=Apple&from=2021-08-01&sortBy=popularity&apiKey=e0b19add227d45a68147c7c5fd2b2f28"

        val jsonObjectRequest = JsonObjectRequest(
            Request.Method.GET,url,null,Response.Listener { response ->
                Toast.makeText(this,"succ",Toast.LENGTH_SHORT).show()
                val newsJsonArray = response.getJSONArray("articles")
                val newsArray = ArrayList<News>()
                for(i in 0 until newsJsonArray.length()) {
                    val newsJsonObject = newsJsonArray.getJSONObject(i)
                    val news = News(
                        newsJsonObject.getString("title"),newsJsonObject.getString("author"),newsJsonObject.getString("url"),newsJsonObject.getString("urlToImage")
                    )
                    newsArray.add(news)
                }


                mAdapter.updateNews(newsArray)
            },Response.ErrorListener { error ->

                Toast.makeText(this,error.toString(),Toast.LENGTH_LONG).show()
            }
        )
        MySingleton.getInstance(this).addToRequestQueue(jsonObjectRequest)

    }
