如何为Volley请求设置自定义标头？目前，已经有一种方式来设置POST请求的主体内容。我有一个简单的GET请求，但我需要传递自定义标头。我不知道JsonRequest类是否支持这样做。它是否可能实现？

那是我的代码，别忘了 = 对象：如果不放就不起作用

val queue = Volley.newRequestQueue(this)
        val url = "http://35.237.133.137:8080/lamarrullaWS/rest/lamarrullaAPI"
        // Request a string response from the provided URL.
        val jsonObjectRequest = object: JsonObjectRequest(Request.Method.GET, url, null,
                Response.Listener { response ->
                    txtPrueba.text = "Response: %s".format(response.toString())
                },
                Response.ErrorListener { txtPrueba.text = "That didn't work!" }
        )
        {
            @Throws(AuthFailureError::class)
            override fun getHeaders(): Map<String, String> {
                val headers = HashMap<String, String>()
                headers.put("Content-Type", "application/json")
                return headers
            }
        }
        queue.add(jsonObjectRequest)

试一下这个

 public void VolleyPostReqWithResponseListenerwithHeaders(String URL,final Map<String, String> params,final Map<String, String> headers,Response.Listener<String> responseListener) {


    String url = URL;

    Log.i("url:", ":" + url);
    StringRequest mStringRequest = new StringRequest(Request.Method.POST,
            url, responseListener, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            // error


            //Log.d("Error.Response", error.getLocalizedMessage());
        }
    }){
        @Override
        protected Map<String, String> getParams() {
            return params;
        }

        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            return headers;
        }
    };



    mStringRequest.setRetryPolicy(new DefaultRetryPolicy(
            60000,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

    mStringRequest.setShouldCache(true);



    //  dialog.show();
    SingletonRequestQueue.getInstance(context).addToRequestQueue(mStringRequest);
}

这是从Github示例中设置标头的代码：

StringRequest myReq = new StringRequest(Method.POST,
                       "http://ave.bolyartech.com/params.php",
                        createMyReqSuccessListener(),
                        createMyReqErrorListener()) {

 protected Map<String, String> getParams() throws 
         com.android.volley.AuthFailureError {
                        Map<String, String> params = new HashMap<String, String>();
                        params.put("param1", num1);
                        params.put("param2", num2);
                        return params;
                    };
                };
                queue.add(myReq);
