translate POST request to API in PHP to Swift - php

Question

Hello I'm trying to translate POST request api code written in php:
<?php
$methodParams = '{
"date_confirmed_from": 1407341754,
"get_unconfirmed_orders": false
}';
$apiParams = [
"method" => "getOrders",
"parameters" => $methodParams
];
$curl = curl_init("https://api.baselinker.com/connector.php");
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_HTTPHEADER, ["X-BLToken: xxx"]);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($apiParams));
$response = curl_exec($curl);
To Swift but I don't have idea why it doesn't work:
import UIKit
struct Parameters: Codable {
let date_confirmed_from: Int
let get_unconfirmed_orders: Bool
}
struct BodyData: Codable {
let method: String
let parameters:Parameters
}
let url = URL(string: "https://api.baselinker.com/connector.php")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.allHTTPHeaderFields = [
"X-BLToken": "xxx"
]
let bodyData = BodyData(method: "getOrders", parameters: Parameters(date_confirmed_from: 1407341754, get_unconfirmed_orders: false))
let encoder = JSONEncoder()
do {
let encodeData = try encoder.encode(bodyData)
request.httpBody = encodeData
let session = URLSession(configuration: .default)
let task = session.dataTask(with: request) { (data, response, error) in
if let error = error {
print(error)
}
if let data = data {
}
}
task.resume()
}catch {
print(error)
}
When I'm testing my Swift code I'm getting error answer from API can someone help me to find fault in my code?

Answer 1

Does the PHP curl work?
It is not what the baseline documentation is asking for.
The documentation asks for this post data:
array (
'method' => 'getOrders',
'parameters' => '{"date_from": 1407341754}',
)
Your PHP curl request post data:
'array (
'method' => 'getOrders',
'parameters' => '{
"date_confirmed_from": 1407341754,
"get_unconfirmed_orders": false
}',
)'
The documentation asks
parameters = arguments of the requested function in JSON format.
Your parameters are an array, not JSON.

Okay I find out solution for this problem:
import UIKit
let url = URL(string: "https://api.baselinker.com/connector.php")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.setValue("application/x-www-form-urlencoded",forHTTPHeaderField: "Accept")
request.setValue("xxx",forHTTPHeaderField: "X-BLToken")
let data: Data = "method=getOrders&parameters={\"date_confirmed_from\": 1407341754&\"get_unconfirmed_orders\":false}".data(using: .utf8)!
request.httpBody = data
let session = URLSession(configuration: .default)
let task = session.dataTask(with: request) { (data, response, error) in
if let error = error {
print(error)
}
if let data = data {
let dataString = String(data: data, encoding: .utf8)
print(dataString!)
}
}
task.resume()
The biggest problem was coding of data. curl in PHP by default sending data as x-www-form-urlencoded
