PHP: curl script fails - php

Question

The task seemed simple.
The login (email) used for authentication must be passed in the login request parameter. In the request body (Body), the user password is passed as a string encoded in UTF-8.
Example request:
POST /auth/authenticate-by-pass?login=testlogin#testDomain.net HTTP/1.1
Host: somehost.ru
Body: somepassword
Cache-Control: no-cache
If the request is successful, the response will contain a JSON object
Tried to do like this:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://somehost.ru/auth/authenticate-by-pass?login=mylogin#mydomain.com");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt($ch, CURLOPT_POST, true );
curl_setopt($ch, CURLOPT_POSTFIELDS, "mypassword" );
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/plain', 'Host: somehost.ru'));
$result=curl_exec($ch);
$php_obj = json_decode($result, true);
print_r($php_obj);
No result. Nothing is displayed. Please help.

Answer 1

In my understanding what you need can be simply (please amend the headers to further suit your needs if necessary) :
$ch = curl_init();
$post = [
'password' => 'xxxxxx'
];
curl_setopt($ch, CURLOPT_URL, 'http://somehost.ru/auth/authenticate-by-pass?login=mylogin#mydomain.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$headers = array();
$headers[] = 'Content-Type: application/x-www-form-urlencoded';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
$php_obj = json_decode($result, true);
print_r($php_obj);
curl_close($ch);

Solved the problem. Ken Lee and everyone else thanks for the help.
$ch = curl_init();
$post = 'mypassword';
curl_setopt($ch, CURLOPT_URL, 'http://somehost.ru/auth/authenticate-by-pass?login=mylogin#mydomain.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$headers = array();
$headers[] = 'Content-Type: application/x-www-form-urlencoded';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
$php_obj = json_decode($result, true);
print_r($php_obj);
curl_close($ch);
