Curl to wp_remote_post convert - php

Question

I would like to convert these into wp_remote_post()
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, "https://clients6.google.com/rpc");
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_POSTFIELDS, '[{"method":"pos.plusones.get","id":"p","params":{"nolog":true,"id":"'.rawurldecode($this->url).'","source":"widget","userId":"#viewer","groupId":"#self"},"jsonrpc":"2.0","key":"p","apiVersion":"v1"}]');
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
$curl_results = curl_exec ($curl);
curl_close ($curl);
$json = json_decode($curl_results, true);
I almost tried with this
$params = array(
'method' => 'POST',
'timeout' => 45,
'blocking' => true,
'headers' => array(
'Content-Type' => 'application/json'
),
'body' => array(
'method' => 'pos.plusones.get',
'id' => 'p',
'params'=> array (
'nolog' => true,
'id' => rawurldecode($url),
'source' => 'widget',
'userId' => '#viewer',
'groupId' => '#self',
),
'jsonrpc' => '2.0',
'key' => 'p',
'apiVersion' => 'v1',
),
);
$connection = wp_remote_post('https://clients6.google.com/rpc', $params);
But there is a error message like this - "Unable to parse json"
Please help
Thank You

This works
$params = array(
'method' => 'POST',
'timeout' => 45,
'blocking' => true,
'headers' => array(
'Content-Type' => 'application/json'
),
'body' => '['.json_encode( array(
'method' => 'pos.plusones.get',
'id' => 'p',
'params' => array(
'nolog' => true,
'id' => rawurldecode( $url ),
'source' => 'widget',
'userId' => '#viewer',
'groupId' => '#self',
),
'jsonrpc' => '2.0',
'key' => 'p',
'apiVersion' => 'v1',
) ).']'
);
$connection = wp_remote_post( 'https://clients6.google.com/rpc', $params );

Noticed a few inconsistencies. not sure if the syntax is throwing the errors but might fix the parsing....
$params = array(
'method' => 'POST',
'timeout' => 45,
'blocking' => true,
'headers' => array(
'Content-Type' => 'application/json'
),
'body' => array(
'method' => 'pos.plusones.get',
'id' => 'p',
'params'=> array(
'nolog' => true,
'id' => rawurldecode($url),
'source' => 'widget',
'userId' => '#viewer',
'groupId' => '#self'
),
'jsonrpc' => '2.0',
'key' => 'p',
'apiVersion' => 'v1'
)
);
