RabbitMQ create user programmatically web

Question

I'm developing a web site which allows the administrator to create users on RabbitMQ. I checked the RabbitMQ api doc, and found an example to create user on windows/unix prompt. The command line seens like this:

curl -i -u ADMIN_USER: ADMIN_PASSW -H "content-type:application/json" -XPUT
{"password":"PASSW_WRITTEN","tags":"administrator"}
http://IP_ADRESS:PORT/api/users/USER_NAME

Here follows the link to the doc

http://hg.rabbitmq.com/rabbitmq-management/raw-file/rabbitmq_v3_4_1/priv/www/api/index.html

In the prompt, it works fine. But on a web site, I have no idea how to send this command.

Note I'm developping on Java Web with JSF, but any other web language example is welcome.

Thanks for any help.

After a long time searching on the internet, I finally found how to create users on RabbitMQ programmatically. Basically, you have to send a HTTP request with PUT or POST "status". Since I'm developing on Java Web, I could easily find a Java library to support me. I used Apache HTTP library, you can find it here:

http://hc.apache.org/downloads.cgi

So, my Java code it's posted below:

For libs, imports:

import org.apache.http.client.methods.HttpPut;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.commons.codec.binary.Base64;

The code to create a new User:

// First, save your user/pw with permission to create new users.
// NOTE: this user is already created on RabbitMQ with permission to create new users
String enc = new String( Base64.encodeBase64( "USER_NAME_WITH_PERMISSION:PASS_W".getBytes() ) );

try{
  HttpPut putCriaUsuario = new HttpPut( "http://RABBIT_MQ_IP:PORT/api/users/USER_NAME_TO_CREATE );
  putCriaUsuario.addHeader( "Authorization", "Basic " + enc ); // RabbitMQ requires a user with create permission, create it mannually first
  putCriaUsuario.addHeader( "content-type", "application/json" );
  putCriaUsuario.setEntity( new StringEntity( "{\"password\":\"YOUR_PASS_WORD\",\"tags\":\"none\"}" ) );
  client.execute( putCriaUsuario );

//After create, configure RabbitMQ permissions

  HttpPut putConfiguraPermissoes = new HttpPut( "http://RABBIT_MQ_IP:PORT/api/permissions/QUEUE_NAME/USER_NAME_CREATED" );
  putConfiguraPermissoes.addHeader( "Authorization", "Basic " + enc );
  putConfiguraPermissoes.addHeader( "content-type", "application/json" );
  putConfiguraPermissoes.setEntity( new StringEntity( "{\"configure\":\"^$\",\"write\":\".*\",\"read\":\".*\"}" ) ); // Permission you wanna. Check RabbitMQ HTTP API for details
  client.execute( putConfiguraPermissoes );
  
}catch( UnsupportedEncodingException ex ){
  ex.printStackTrace();
}catch( IOException ex ){
  ex.printStackTrace();
}

This is Java, so it can be used on desktop application or Java Web. On other language follows the same logic, just with another libs. Hope it help us all. Fells happy for sharing knowledge!

for those who are facing a problem with granting permission this one works for me

HttpPut putConfiguraPermissoes = new HttpPut("http://127.0.0.1:15672/api/permissions/%2F/THE_NAME_OF_THE_NEW_USER" );  
putConfiguraPermissoes.addHeader( "Authorization", "Basic " + enc );
putConfiguraPermissoes.addHeader( "content-type", "application/json" );
putConfiguraPermissoes.setEntity( new StringEntity( "{\"configure\":\".*\",\"write\":\".*\",\"read\":\".*\"}" ) );
CloseableHttpClient client2 = HttpClients.createDefault();
lient2.execute( putConfiguraPermissoes );
