Volley:[355] NetworkDispatcher.processRequest:未处理的异常 java.lang.IllegalArgumentException

问题描述

我正在尝试运行以下代码将数据发布到在线 MySQL 数据库

Hi I'm trying to run the below code to post data to a an online MySQL database

    if (data.getCount() > 0) {
                    data.moveToFirst();
                    do {
                        save(orderId,client, data.getString(0),data.getString(3),String.valueOf(finalCost),data.getString(4),longitude,latitude,"_",progressDialog);
                    } while (data.moveToNext());
                       data.close();
                    mydb.clearCart();

    private void save(final String orderId, final String client, final String prodid, final String Seller, final String amount, final String quantity, final double longi, final double lat, final String location, final ProgressDialog progressDialog) {
    String URL_ORDER = "https://foodfuzz.co.ke/foodfuzzbackend/market/orders/order.php";
    StringRequest orderStringRequest = new StringRequest(Request.Method.POST, URL_ORDER,
            //android M

            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    try {
                        JSONObject orderObject = new JSONObject(response);
                        String orderSuccess = orderObject.getString("success");
                        if(orderSuccess.equals("1")){
                            pay.setVisibility(View.GONE);
                            progressDialog.dismiss();
                            Toast.makeText(CheckOutActivity.this,"Order Placed Successfully " , Toast.LENGTH_SHORT).show();
                        }else{
                            Logger.getLogger("Error",orderObject.getString("message"));
                            pay.setVisibility(View.GONE);
                            progressDialog.dismiss();
                            Toast.makeText(CheckOutActivity.this,"Order failed "+orderObject.getString("message") , Toast.LENGTH_SHORT).show();
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                        progressDialog.dismiss();
                        Toast.makeText(CheckOutActivity.this,"Unable to place order " + e.toString(), Toast.LENGTH_SHORT).show();
                        pay.setEnabled(true);
                    }
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    progressDialog.dismiss();
                    error.printStackTrace();
                    Toast.makeText(CheckOutActivity.this,"Error placing order " + error.toString(), Toast.LENGTH_SHORT).show();
                    pay.setEnabled(true);
                }
            }){
        protected Map<String, String> getParams() {
            Map<String, String> params = new HashMap<>();
            params.put("orderId",orderId);
            params.put("client", client);
            params.put("name", prodid);
            params.put("seller", Seller);
            params.put("amount", amount);
            params.put("quantity",quantity);
            params.put("longitude",String.valueOf(longi));
            params.put("latitude",String.valueOf(lat));
            params.put("location",location);
            return params;
        }
    };
    RequestQueue orderRequestQueue = Volley.newRequestQueue(this);
    orderRequestQueue.add(orderStringRequest);

}

数据来自可正确检索的 sqlite 数据库.当我在低于 26 的 android 版本上运行它时它可以正常工作，但在高于 26 的版本上我得到以下错误

The data is from an sqlite database wchich is retrieving it correctly. When I run this on android version less that 26 it works correctly but on version greater than 26 I get the error bellow

我是否需要更新代码以处理新版本?如果是，那是什么?

Could there be something that I need to update on my code to take care of the new version? If yes what is it?

推荐答案

它在堆栈跟踪中说明了

It says it in the stacktrace

java.lang.IllegalArgumentException:Request#getParams() 或 Request#getPostParams() 返回一个包含空键或值的映射:(客户端，空).所有键和值都必须非空.

protected Map<String, String> getParams() {
    Map<String, String> params = new HashMap<>();
    params.put("orderId",orderId);
    params.put("client", client);  // <<<  HERE
    params.put("name", prodid);
    params.put("seller", Seller);
    params.put("amount", amount);
    params.put("quantity",quantity);
    params.put("longitude",String.valueOf(longi));
    params.put("latitude",String.valueOf(lat));
    params.put("location",location);
    return params;
}

您的 client 值为 null : params.put("client", client);
