尝试通过以下方式发送请求：

RequestQueue requestQueue = Volley.newRequestQueue(BP_Details.this);
StringRequest strReq = new StringRequest(Request.Method.POST,
            URL, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            Log.i("response", response);
        } 
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Log.e(TAG, "Login Error: " + error.getMessage());
            Toast.makeText(getApplicationContext(),
                    error.getMessage(), Toast.LENGTH_LONG).show();
        }
    }){

        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
            Log.e(TAG,"Inside getParams");

            // Posting parameters to url
            Map<String, String> jsonBody = new HashMap<>();
            jsonBody.put("COMPANY_NO",s);
            jsonBody.put("LOCATION_NO",s1);
            jsonBody.put("BP_CODE",code);
            jsonBody.put("NAME",name);
            jsonBody.put("ADDRESS1",address1);
            jsonBody.put("ADDRESS2",address2);
            jsonBody.put("CITY",city);
            jsonBody.put("STATE",state);
            jsonBody.put("COUNTRY",country);
            jsonBody.put("ZIP",zip);
            jsonBody.put("AREA_CODE",area);
            jsonBody.put("EMAIL",email);
            jsonBody.put("CURRENCY",currency);
            jsonBody.put("TIN_GRN",tin);
            jsonBody.put("CST_NO",cst);
            jsonBody.put("PAN_NO",pan);
            jsonBody.put("SALES_PERSON_NO",salesPname);
            jsonBody.put("PHONE_NO",mobile);
            jsonBody.put("LOCATION",cLocation);

            return params;
        }
    };
    // Adding request to request queue
    queue.add(strReq);
