java - Volley 库在发布请求时给出错误 500

Question

我有以下代码，用于将数据保存到 mysql 数据库中；

    private void save(final String orderId, final String client, final String name, 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,
            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")){
                            Toast.makeText(CheckOutActivity.this,"Order Placed Successfully " , Toast.LENGTH_SHORT).show();
                            pay.setVisibility(View.GONE);
                        }
                    } 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();
                    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<String, String>();
            params.put("orderId",orderId);
            params.put("name", name);
            params.put("client", client);
            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);

}

我的问题是，当我发出 post 请求时，收到错误代码 500。以下是logcat上实际记录的错误

BasicNetwork.performRequest: Unexpected response code 500 for https://foodfuzz.co.ke/foodfuzzbackend/market/orders/order.php

这是服务器上指定网址上的 php 代码

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    require_once '../db/connector.php';
    $orderId = mysqli_real_escape_string($conn, $_POST['orderId']);
    $client = mysqli_real_escape_string($conn, $_POST['client']);
    $product = mysqli_real_escape_string($conn, $_POST['name']);
    $seller = mysqli_real_escape_string($conn, $_POST['seller']);
    $amount = mysqli_real_escape_string($conn, $_POST['amount']);
    $quantity = mysqli_real_escape_string($conn, $_POST['quantity']);
    $longi = mysqli_real_escape_string($conn, $_POST['longitude']);
    $lati = mysqli_real_escape_string($conn, $_POST['latitude']);
    $loc = mysqli_real_escape_string($conn, $_post['location']);
    $status = 1;

    $sql = "INSERT INTO tbl_orders (orderid, client, product, seller, amount, quantity, longitude, latitude, deliveryloc, status) VALUES ('$orderId', '$client', '$product', '$seller', '$amount', '$quantity', '$longi', '$lati', '$loc', '$status')";

    if (mysqli_query($conn, $sql)) {
        $result["success"] = "1";
        $result["message"] = "success";

        echo json_encode($result);
        mysqli_close($conn);
    } else {

        $result["success"] = "0";
        $result["message"] = "error";

        echo json_encode($result);
        mysqli_close($conn);
    }
}

该代码在 postman 上运行，没有任何错误。我可能做错了什么

此错误通常是由您的代码错误引起的，首先最好检查您的 php 脚本以及其他代码是否没有错误。就我而言，发布数据与表列不匹配。
