Question

我正在尝试通过Json从在线API获取一些数据，但是由于以前从未做过，所以无法弄清楚身份验证的工作原理。它不是用户密码对，而是基于唯一密钥。卷毛看起来像这样：

curl -X GET --header'Accept：application / json'--header“ authorization：Bearer [ unique key ]”'URL to Json Object'

没有做太多尝试，因为我是在Java中实现json的新手。该列表未加载，并且正在logcat中获取以下内容：

E / Volley：[31231] BasicNetwork.performRequest：URL的意外响应代码403

public class MainActivity extends AppCompatActivity {
private RecyclerView mRecyclerView;
private PlayerListAdapter mAdapter;
private ArrayList<PlayerListItem> mPlayerList;
private RequestQueue mRequestQueue;

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

    mRecyclerView = findViewById(R.id.playerList);
    mRecyclerView.setHasFixedSize(true);
    mRecyclerView.setLayoutManager(new LinearLayoutManager(this));

    mPlayerList = new ArrayList<>();

    mRequestQueue = Volley.newRequestQueue(this);
    parseJson();
}

private void parseJson() {
    String url = getString(R.string.url_to_members);

    JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
            new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    try {
                        JSONArray jsonArray = response.getJSONArray("items");

                        for (int i = 0; i < jsonArray.length(); i++) {
                            JSONObject players = jsonArray.getJSONObject(i);

                            String playerName = players.getString("name");
                            String playerRole = players.getString("role");
                            int playerTrophies = players.getInt("trophies");
                            int playerDonations = players.getInt("donations");

                            mPlayerList.add(new PlayerListItem(playerName, playerRole, playerTrophies, playerDonations));
                        }

                        mAdapter = new PlayerListAdapter(MainActivity.this, mPlayerList);
                        mRecyclerView.setAdapter(mAdapter);
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            error.printStackTrace();
        }
    }) {
        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            Map<String, String> headers = new HashMap<>();
            String apiToken = "Bearer" + Base64.encodeToString(getString(R.string.api_key).getBytes(), Base64.NO_WRAP);
            headers.put("Accept:", "application/json");
            headers.put("authorization:", "Bearer " + apiToken);
            return headers;
        }
    };

    mRequestQueue.add(request);
}
}

解析Json时无法弄清楚标头身份验证的工作方式
