Android Volley：不附加标头

Question

我正在尝试在我的 Android 应用程序中实现标记化，为此我总是需要在我向服务器发送授权标头时将其添加到我的请求中。问题是，当我调试服务器实例时，即使发出请求，也没有在其中添加 Authorization 标头

这是我的代码

private void syncDatabases()
{
    String tag_json_obj = "json_obj_req";
    String uri = "random_url";
    final ProgressDialog pDialog = new ProgressDialog(this);
    pDialog.setMessage("Please wait while syncing");
    pDialog.show();

    List<Plane> allPlane = service.gettAllPlane();
    Gson gson = new Gson();
    JSONArray jsArray = new JSONArray();

    for (Plane p : allPlane)
    {
        String jsonString = gson.toJson(p);
        try {
            JSONObject obj = new JSONObject(jsonString);
            obj.remove("ID");
            jsArray.put(obj);

        } catch (JSONException e) {
            e.printStackTrace();
        }
    }

    JsonArrayRequest jsonObjReq = new JsonArrayRequest(Request.Method.POST, uri, jsArray, new Response.Listener<JSONArray>()
    {
        @Override
        public void onResponse(JSONArray response)
        {
            ArrayList<Plane> newList = new ArrayList<>();
            try
            {
                for(int i=0;i<response.length();i++)
                {
                    String planeName,planeEngine,planeProducer,planeCountry,planeYear,wikiLink,ID;
                    JSONObject pl = response.getJSONObject(i);

                    String p1 = pl.optString("ID");
                    if (pl != null && !p1.isEmpty())
                        ID = pl.getString("ID");
                    else
                        ID = "0";

                    String p2 = pl.optString("planeName");
                    if (p2 != null && !p2.isEmpty())
                        planeName = pl.getString("planeName");
                    else
                        planeName = "";

                    String p3 = pl.optString("planeEngine");
                    if (p3 != null && !p3.isEmpty())
                        planeEngine = pl.getString("planeEngine");
                    else
                        planeEngine = "";

                    String p4 = pl.optString("planeProducer");
                    if (p4 != null && !p4.isEmpty())
                        planeProducer = pl.getString("planeProducer");
                    else
                        planeProducer = "";

                    String p5 = pl.optString("planeCountry");
                    if (p5 != null && !p5.isEmpty())
                        planeCountry = pl.getString("planeCountry");
                    else
                        planeCountry = "";

                    String p6 = pl.optString("planeYear");
                    if (p6 != null && !p6.isEmpty())
                        planeYear = pl.getString("planeYear");
                    else
                        planeYear = "0";

                    String p7 = pl.optString("wikiLink");
                    if (p7 != null && !p7.isEmpty())
                        wikiLink = pl.getString("wikiLink");
                    else
                        wikiLink = "";

                    Plane plf = new Plane(Integer.parseInt(ID),planeName,planeEngine,planeProducer,planeCountry,Integer.parseInt(planeYear),wikiLink);
                    newList.add(plf);
                }
            }
            catch (JSONException e)
            {
                e.printStackTrace();
            }

            service.deleteAllFromPlane();
            for (Plane p : newList)
            {
                boolean ok = service.addNewPlane(p);
            }
            pDialog.dismiss();
            tab1.onIorU();

        }

    }, new Response.ErrorListener()
    {
        @Override
        public void onErrorResponse(VolleyError error)
        {
            Log.e("ERROR", "Error occurred ", error);
            pDialog.dismiss();
        }
    })
    {
        @Override
        public Map<String, String> getHeaders() throws AuthFailureError
        {
            SharedPreferences settings = PreferenceManager
                    .getDefaultSharedPreferences(MainActivity.this);
            String auth_token_string = settings.getString("token", "");

            Map<String, String> params = new HashMap<>();
            params.put("Content-Type", "application/json; charset=UTF-8");
            params.put("Authorization", auth_token_string);
            return params;
        }
    };

我已经验证了 auth_token_string 是否为空（不是）。这是我在服务器端看到的（C# Web API 2 服务器）

这是我获取标题的方式：

var authorization = request.Headers.Authorization;

在图片中，您可以看到我尝试在标头字段中发送的令牌的一部分。我究竟做错了什么？谢谢。

在您的授权令牌中，您缺少授权类型。我假设您使用的是 Bacis 身份验证，所以请尝试使用：

params.put("Authorization", "Basic " + auth_token_string);
