Can't hit Web API from php - php

Question

I'm trying to call this
[Route("CreateHL7TestFile")]
[HttpPost]
public IActionResult CreateHL7TestFile([FromBody] JObject data)
{
// Code here
}
from a php function using cUrl. When I try and call the API without passing any data it works fine. It's when I try and add the '$data' that I cannot hit the API. When I call the API with data from Postman it also works fine. So I'm assuming my error is on the php side?
My php function looks like this.
public function CallAPI($method, $url, $data = false)
{
$data = array("value1" => "some value");
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query(array('test1' => 'value1', 'test2' => 'value2')));
$result = curl_exec($ch);
print_r($result);
curl_close($ch);
}
http://localhost:50999/api/ParticipantAPI/CreateHL7TestFile
Any help would be much appreciated.
Thanks,

Answer 1

Use a proper model on the asp.net-core server to bind incoming data
public class MyData {
public string value1 { get; set;}
}
And update action accordingly
[Route("CreateHL7TestFile")]
[HttpPost]
public IActionResult CreateHL7TestFile([FromBody] MyData data) {
// Code here
}
Referencing the following article POSTing JSON Data With PHP cURL
Try the following on the PHP side
$data = array("value1" => "some value");
$data_string = json_encode($data);
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string))
);
$result = curl_exec($ch);
print_r($result);
curl_close($ch);
For your real requests refactor the expected data model accordingly.

Try something like this:
public function CallAPI($method, $url, $data = false)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query(array('test1' => 'value1', 'test2' => 'value2')));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
print_r($result);
curl_close($ch);
}

If you want to send json, then I think you'll have to set the header, something like:
public function CallAPI($method, $url, $data = false)
{
$dat = array("TEST1","TEST2");
$data = json_encode($dat);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
print_r($result);
curl_close($ch);
}
