fetch data from an API with the use of ID in flutter - flutter

Question

I work on a delivery man application and I need to have from an API the details of an order received on the account of a delivery man.
here is an example:
{
"Status": "1",
"Order": {
"deliveryCost": "5.000",
"amount": "38.400",
"total": "43,400",
"hors_remise": "34.560",
"Dishes": [
{
"cartID": "00000",
"dishID": "13548",
"dimensionID": 0,
"title": "Classic 16 pieces trays:",
"ingredient": "10 piece trays + 2 gunkan + 4 shrimp crunchy",
"price": "38.400",
"quantity": "1",
"imagePath": "https://www.monresto.net/test/plats/P_170121112803.jpg",
"Options": []
}
],
and to access of all this information I must specify the "KEY" I had on the postan
my question is how can i add (orderID)?
there is my code :
import 'package:http/http.dart' as http;
import 'dart:convert';
import 'package:flutter/material.dart';
class datePageClass extends StatefulWidget {
#override
_datePageClassState createState() => _datePageClassState();
}
class _datePageClassState extends State<datePageClass> {
void getData() async {
http.Response response = await http.post(
'https://api/ws/v3/Delivery/orderDetails.php');
if (respo
nse.statusCode == 200) {
String data = response.body;
var cmddetails = jsonDecode(data);
print(cmddetails);
} else {
print(response.statusCode);
}
print('');
}
#override
Widget build(BuildContext context) {
getData();
return MaterialApp(
home: Scaffold(
backgroundColor: Colors.lightBlue,
),
);
}
}

Answer 1

Did you try this?
var response = await http.post('https://www.apiurl.com/ws/v2/details.php', body: {'OrderID': 1209, 'OtherParam': 'value'});
Then in PHP
$OrderID = $_POST["OrderID"];
$OtherParam = $_POST["OtherParam"];
Make sure to sanitize the variables to avoid SQL Injections
And then you can send JSON back to dart/flutter.

Pre-check: Are your sure that this URL expects http-POST not http-GET?
You want to add orderID to the request, right?
If that's the case, first you need to find if API expects this parameter as query parameter or part of the body.
Nevertheless, here are examples for both cases.
String orderDetailsUrl = 'https://www.monresto.net/ws/v3/Delivery/orderDetails.php';
orderID as query parameter:
orderDetailsUrl += "?orderID=FIXME_ORDER_ID";
http.Response response = await http.post(orderDetailsUrl);
orderID as part of request body:
Map<String, dynamic> data = Map()
..putIfAbsent("orderID", () => "FIXME_ORDER_ID")
var body = jsonEncode(data);
http.Response response = await http.post(orderDetailsUrl, headers: {"Content-Type": "application/json"}, body: body);
