Password
If the Control Password is enabled on WebRelay-10 and the state.xml page is requested through a
browser, the user will be prompted for a password. If the XML request is sent from an XML application,
the html request will need to contain the password, encoded as Base64. The following is an html request
header without the password:
GET /state.xml?relay1State=1&noReply=1 HTTP/1.1
(Terminated w/ two
\r\n
.)
The following example adds the password:
GET /state.xml?relay1State=1&noReply=1 HTTP/1.1
(Terminated with
\r\n
.)
Authorization: Basic bm9uZTp3ZWJyZWxheQ==
(Terminated with two
\r\n
.)
bm9uZTp3ZWJyZWxheQ==
is the Base64 encoded version of the user “name:password,”
none:webrelay.
A utility is provided at http://www.controlbyweb.com/encoder to encode the password. Simply type the
string username:password into the website and press 'Encode'.
