添加带有截击请求和响应的自定义头为“data”:“此字段是必需的”

我刚开始使用定制请求截击请求这里是我用来发送定制头的代码的和平。标题必须是 headers.put(“Accept”,“application/json”); headers.put(“内容类型”,“应用程序/json”);

邮递员行数据

和 标题

StringRequest stringRequest = new StringRequest(Request.Method.POST,
            WebConstants.BASE_URL + method,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {

                    if (dialog != null)
                        dialog.dismiss();

                    if (response != null) {
                        dialog.dismiss();
                        Log.e("res", response);
                        //    eventHandler.onResponse("" + method, response);
                    }

如果我这边有什么问题,请告诉我。
