XQuery/Basic Authentication
Appearance
< XQuery
Motivation
[edit | edit source]You want to use a very basic login process over a secure network such as a secure Intranet or over an SSL connection.
Method
[edit | edit source]We will used the base64 encoding and decoding tools to generate the right strings.
xquery version "1.0";
let $user := 'Aladdin'
let $password := 'open sesame'
let $credentials := concat($user, ':', $password)
let $encode := util:string-to-binary($credentials)
return
<results>
<user>{$user}</user>
<password>{$password}</password>
<encode>{$encode}</encode>
</results>
Returns the following:
<results>
<user>Aladdin</user>
<password>open sesame</password>
<encode>QWxhZGRpbjpvcGVuIHNlc2FtZQ==</encode>
</results>
Sample HTTP GET using Basic Authentication
[edit | edit source]xquery version "1.0";
declare function local:basic-get-http($uri,$username,$password) {
let $credentials := concat($username,":",$password)
let $credentials := util:string-to-binary($credentials)
let $headers :=
<headers>
<header name="Authorization" value="Basic {$credentials}"/>
</headers>
return httpclient:get(xs:anyURI($uri),false(), $headers)
};
let $host := "http://localhost:8080"
let $path := "/exist/rest/db/apps/terms/data/1.xml"
let $uri := concat($host, $path)
let $user := 'my-login'
let $password := 'my-password'
return local:basic-get-http($uri,$username,$password)
