How to Set Custom Header in Volley Request

How to set custom header in Volley Request

It looks like you override public Map<String, String> getHeaders(), defined in Request, to return your desired HTTP headers.

How to add a header to a request from volley library

I find my problem and the solution is as like as below

I just replace object with JsonObjectRequest and then use overriding getHeaders function

            val request :JsonObjectRequest = object : JsonObjectRequest(Request.Method.POST,
            URL,
            body,
            Response.Listener<JSONObject> { response ->
                Log.e(tag, response.toString())
            },
            Response.ErrorListener{ error ->
                Log.e(tag, error.message )
            }) {

            @Throws(AuthFailureError::class)
            override fun getHeaders(): Map<String, String> {
                val headers = HashMap<String, String>()
                headers.put("Content-Type", "application/json");
                headers["x-sms-ir-secure-token"] = tokenKey
                return headers
        }

Add custom headers in volley request

you can write a class extends Request.(override getHeaders() and so on)
just like

public abstract class AbsRequest<T> extends Request<T>{

    public AbsRequest(int method, String url, Response.ErrorListener listener) {
        this(method, url, null, listener);
    }

    public AbsRequest(int method, String url, Map<String, String> params, Response.ErrorListener listener) {
        this(method, url, params, null, listener);
    }

    public AbsRequest(int method, String url, Map<String, String> params, Map<String, String> head, Response.ErrorListener listener) {
        this(method, url, params, head, null, listener);
    }

    public AbsRequest(int method, String url, Map<String, String> params, Map<String, String> head, String bodyContentType, Response.ErrorListener listener) {
        this(method, url, params, null, head, bodyContentType, listener);
    }

    public AbsRequest(int method, String url, String body, Map<String, String> head, String bodyContentType, Response.ErrorListener listener) {
        this(method, url, null, body, head, bodyContentType, listener);
    }

    private AbsRequest(int method, String url, Map<String, String> params, String body, Map<String, String> head, String bodyContentType,  Response.ErrorListener listener) {
        super(method, url, listener);
    }
}

How to send Authorization header in Android using Volley library?

StringRequest request = new StringRequest(Request.Method.POST, YourUrl, new Response.Listener<String>() {
    @Override
    public void onResponse(String response) {
        if (!response.equals(null)) {
            Log.e("Your Array Response", response);                    
        } else {
            Log.e("Your Array Response", "Data Null");
        }
    }

}, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        Log.e("error is ", "" + error);
    }
}) {    

 //This is for Headers If You Needed
    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
        Map<String, String> params = new HashMap<String, String>();
        params.put("Content-Type", "application/json; charset=UTF-8");
        params.put("token", ACCESS_TOKEN);
        return params;
    }

 //Pass Your Parameters here
    @Override
    protected Map<String, String> getParams() {
        Map<String, String> params = new HashMap<String, String>();
        params.put("User", UserName);
        params.put("Pass", PassWord);
        return params;
    }
};
RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
queue.add(request);

Set custom headers to all volley requests

I believe the best way is extend the HttpStack sub-class which you choose to use, then intercepting the performRequest() method, put your global headers inside it.

public class MyHurlStack extends HurlStack {
    @Override
    public HttpResponse performRequest(
            Request<?> request, Map<String, String> additionalHeaders)
            throws IOException, AuthFailureError {

        Map<String, String> headers = request.getHeaders();
        // put your global headers
        headers.put("Via", "netroid");
        headers.put("Accept-Charset", "UTF-8");
        headers.put("Origin", "http://netroid.cn/");

        return super.performRequest(request, additionalHeaders);
    }
}

public class MyHttpClientStack extends HttpClientStack {
    public MyHttpClientStack(HttpClient client) {
        super(client);
    }

    @Override
    protected void onPrepareRequest(HttpUriRequest request) throws IOException {
        // put your global headers
        request.setHeader("Via", "netroid");
        request.setHeader("Accept-Charset", "UTF-8");
        request.setHeader("Origin", "http://netroid.cn/");
        super.onPrepareRequest(request);
    }
}

when RequestQueue initializing, use the customize HttpStack instead of.

if (stack == null) {
    if (Build.VERSION.SDK_INT >= 9) {
        stack = new HurlStack();
    } else {
        stack = new MyHttpClientStack(AndroidHttpClient.newInstance(userAgent));
    }
}

Network network = new BasicNetwork(stack);

Adding Header with Specified Parameter in Volley?

how can the authorization :bearer be added in the header section,which
is shown in the Given picture

Use

headers.put("Authorization", "Bearer " + access_token);

instead of

headers.put("access_token", access_token);
