I am not getting expected response from Curl request in PHP

Time:08-18

I have a curl request which is working fine in https://reqbin.com/ and in the Postman but when I implement same in PHP it is not working; Below is plain CURL command;

curl -X POST \
'http://example.com' \
-H 'content-type: application/json' \
-d '{"Header": {"Token": "xyz"}, "Body": {"Email": "[email protected]", "FirstName": "test", "Surname": "test"}}'

The response I am getting from this is;

{"Header":{"Status":"OK"},"Body":{"BackUrl":"https:example.com","Redirect":"YES"}}

But when I implement same in PHP as;

$curl = curl_init();
$headers = array(
    "content-type: application/json"
);

$postData = '{"Header": {"Token": "xyz"}, "Body": {"Email": "[email protected]",  "FirstName": "test", "Surname": "test"}}';

$opt_arr = array(
    CURLOPT_URL => 'http://example.com',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => '',
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 0,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_CUSTOMREQUEST => 'POST',
    CURLOPT_POST => true,
    CURLOPT_HTTPHEADER => $headers,
    CURLOPT_POSTFIELDS => $postData
);
curl_setopt_array($curl, $opt_arr);
echo $resp = curl_exec($curl);
curl_close($curl);

I do not receive the expected response;

{"Header":{"Status":"ERROR","ErrorMsg":"INVALID_REQUEST"},"Body":{"BackUrl":"","Redirect":"NO"}}

I need help converting the above working curl to the correct PHP code.

I am not familiar with PHP, regardless of that I see a difference in sending "Header": {"Token": "xyz"}. The curl command sends it in the post data, whereas PHP sends it in the http headers. The PHP variables should be

$headers = array(
    "content-type: application/json"
);
$postDataHeader = array(
    'Token' => 'xyz'
);
$postDataBody = array(
    'Email' => '[email protected]',
    'FirstName' => 'test',
    'Surname' => 'test'
);
$postData = json_encode(array(
    'Header' => $postDatHeader,
    'Body' => $postDataBody
));

and $postData must be set in CURLOPT_POSTFIELDS, not CURLOPT_HTTPHEADER.

fixed PHP example:

<?php
$ch = curl_init();
curl_setopt_array($ch, array(
    CURLOPT_URL => 'http://example.com',
    CURLOPT_HTTPHEADER => array(
        'content-type: application/json'
    ),
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => json_encode(array(
        'Header' => array(
            'Token' => 'xyz',
        ),
        'Body' => array(
            'Email' => '[email protected]',
            'FirstName' => 'test',
            'Surname' => 'test',
        ),
    ), JSON_THROW_ON_ERROR)
));
curl_exec($ch);

After many unsuccessful attempts in PHP, I tried to implement it in javascript and here I got to know that error is with SSL security, hence I added HTTPS into the URL, and it worked.

$curl = curl_init();
$headers = array(
    "content-type: application/json"
);

$postData = '{"Header": {"Token": "xyz"}, "Body": {"Email": "[email protected]",  "FirstName": "test", "Surname": "test"}}';

$opt_arr = array(
    CURLOPT_URL => 'https://example.com',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => '',
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 0,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_CUSTOMREQUEST => 'POST',
    CURLOPT_POST => true,
    CURLOPT_HTTPHEADER => $headers,
    CURLOPT_POSTFIELDS => $postData
);
curl_setopt_array($curl, $opt_arr);
echo $resp = curl_exec($curl);
curl_close($curl);
