How to define the basic HTTP authentication using cURL correctly?

I'm learning Apigility (Apigility docu -> REST Service Tutorial) and trying to send a POST request with basic authentication via cURL:

$ curl -X POST -i -H "Content-Type: application/hal+json" -H "Authorization: Basic YXBpdXNlcjphcGlwd2Q=" http://apigilityhw.sandbox.loc/status 

YXBpdXNlcjphcGlwd2Q= is the base 64 encoded string with my credentials apiuser:apipwd. The credentials are saved in the /data/htpasswd (apiuser:$apr1$3J4cyqEw$WKga3rQMkxvnevMuBaekg/).

The looks like this:

HTTP/1.1 401 Unauthorized Server: nginx/1.4.7 Date: Mon, 22 Sep 2014 07:48:47 GMT Content-Type: application/problem+json Transfer-Encoding: chunked Connection: keep-alive X-Powered-By: PHP/5.5.12-1~dotdeb.1 WWW-Authenticate: Basic realm="api" 

Where is the mistake here? How to get it work?

How do you use the Basic Authentication in curl?

To send basic auth credentials with Curl, use the "-u login: password" command-line option. Curl automatically converts the login: password pair into a Base64-encoded string and adds the "Authorization: Basic [token]" header to the request.

How do I authenticate an HTTP request?

A client that wants to authenticate itself with the server can then do so by including an Authorization request header with the credentials. Usually a client will present a password prompt to the user and will then issue the request including the correct Authorization header.

How does HTTP basic authentication work?

HTTP basic authentication is a simple challenge and response mechanism with which a server can request authentication information (a user ID and password) from a client. The client passes the authentication information to the server in an Authorization header. The authentication information is in base-64 encoding.

curl -u username:password http:// curl -u username http:// 

From the documentation page:

-u, --user <user:password>

Specify the user name and password to use for server authentication. Overrides -n, --netrc and --netrc-optional.

If you simply specify the user name, curl will prompt for a password.

The user name and passwords are split up on the first colon, which makes it impossible to use a colon in the user name with this option. The password can, still.

When using Kerberos V5 with a Windows based server you should include the Windows domain name in the user name, in order for the server to succesfully obtain a Kerberos Ticket. If you don't then the initial authentication handshake may fail.

When using NTLM, the user name can be specified simply as the user name, without the domain, if there is a single domain and forest in your setup for example.

To specify the domain name use either Down-Level Logon Name or UPN (User Principal Name) formats. For example, EXAMPLE\user and [email protected] respectively.

If you use a Windows SSPI-enabled curl binary and perform Kerberos V5, Negotiate, NTLM or Digest authentication then you can tell curl to select the user name and password from your environment by specifying a single colon with this option: "-u :".

If this option is used several times, the last one will be used.

Note that you do not need --basic flag as it is the default.

as header

AUTH=$(echo -ne "$BASIC_AUTH_USER:$BASIC_AUTH_PASSWORD" | base64 --wrap 0)  curl \   --header "Content-Type: application/json" \   --header "Authorization: Basic $AUTH" \   --request POST \   --data  '{"key1":"value1", "key2":"value2"}' \   https://example.com/
