授权:bearer如何添加到header中 部分，如图所示。

Answer 1

授权:bearer如何添加到header部分，哪个 如图所示

使用

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

而不是

headers.put("access_token", access_token);

Answer 2

您好，使用下面的代码希望它能解决您的问题

public void getDataFromServer(final Context context, String url, Integer method, final Map<String, String> params, final String sector ,final String AaccessToken ) {
    RequestQueue queue = Volley.newRequestQueue(context);
    StringRequest myReq = new StringRequest(Request.Method.GET, url,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {

                }
            },
            new Response.ErrorListener() {

                @Override
                public void onErrorResponse(VolleyError error) {

                }
            }) {

        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            Map<String, String>  params = new HashMap<String, String>();
            params.put("access_token", "your access token");

            return params;
        }

        protected Map<String, String> getParams()
                throws com.android.volley.AuthFailureError {
            return params;
        };


    };



    myReq.setRetryPolicy(new DefaultRetryPolicy(15000,

    queue.add(myReq);
}
