Create a node using the REST API

Question

I am trying to create a node from a different server via REST API, utilizing the Drupal 8 REST API and the Poster plugin for the browser. I posted the request as shown below, and I got the following output.

{
    "message": ""
}

I already enabled the service end_point to create, retrieve, update, and delete the content in the REST API configuration.

What is happening? Is it the right way of doing it?

Answer 1

Okay, I am going to Explain you in a very simple way using a Postman Software.
1. Enable the restui Module.
2. Add the basic_auth authentication.
3. Get the X-CSRF-Token from /rest/session/token.
4. Follow things by this image:

5. Add the following text into your Body.

And hit the Send Button Its Done!

Answer 2

Drupal officially support 2
Authentication providers

1. Cookie
   
2. Basic_auth
   

( Note ) Personally, I recommend ‘Cookie’,
because it is useful for mobile and third-party developers.

Answer 3

My plan was first make it work using the postman client and port the same using curl request . So first i made a curl request from command line as

curl --include --request POST --user username:password --header 'Content-type: application/hal+json' http://192.168.1.243/node --data-binary '{"_links":
{"type":{"href":"http://192.168.1.243/rest/type/node/article"}}, "title":[{"value":"My first page"}],"body":[{"value":"How are you?"}]}'

And that was worked (created the node in 192.168.1.243) . Then i made the curl request from php as follows :

$data = '{"_links":
{"type":{"href":"http://192.168.1.243/rest/type/node/article"}}, "title":[{"value":"My first page"}],"body":[{"value":"How are you?"}]}';

        $url = "http://192.168.1.243/node";
        $curl_connection = curl_init($url);
        curl_setopt($curl_connection, CURLOPT_COOKIEFILE, "/tmp/cookie.txt");
        curl_setopt($curl_connection, CURLOPT_COOKIEJAR, "/tmp/cookie.txt");
        curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
        curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($curl_connection, CURLOPT_CUSTOMREQUEST, 'POST');
        curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $data);
        curl_setopt($curl_connection, CURLOPT_HTTPHEADER, array('Content-type: application/hal+json'));
        curl_setopt($curl_connection, CURLOPT_USERPWD, "$username:$password");
        curl_setopt($curl_connection, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);

And that was all . The node created in the remote server .

In postman client cant set the HEADER as 'Content-type: application/hal+json' . I think that may caused the issue . Any insights welcome .
