Generate a one-time, quick expiration challenge to be used in challenge/response authentication methods.
Inputs
None.
Example Request
POST /interface/xmlrpc HTTP/1.0 User-Agent: XMLRPC Client 1.0 Host: www.dreamwidth.org Content-Type: text/xml Content-Length: 97 <?xml version="1.0"?> <methodCall> <methodName>LJ.XMLRPC.getchallenge</methodName> <params> <param> <value><struct></struct></value> </param> </params> </methodCall>
Outputs
auth_scheme Scalar. Required. You can ignore this for now. By default this is the highest version of our authentication schemes, if in the future if we implement other auth schemes or change the default. In that case we'd add a new capabilities exchange: Your client could say, "I know c0 and c1", and our server would then say, "Use c1, it's the best."
challenge Scalar. Required. An opaque cookie to generate a hashed response from.
expire_time Scalar. Required. The expiration time of the challenge, as measured in seconds since the Unix epoch.
server_time Scalar. Required. The server time when the challenge was generated, as measured in seconds since the Unix epoch.
Example Response
HTTP/1.1 200 OK Connection: close Content-length: 557 Content-Type: text/xml Date: Tue, 16 Jul 2002 00:30:01 GMT Server: Apache/1.3.4 (Unix) <?xml version="1.0"?> <methodResponse> <params> <param> <value><struct> <member> <name>auth_scheme</name> <value><string>c0</string></value> </member> <member> <name>challenge</name> <value><string>c0:1073113200:2831:60:2TCbFBYR72f2jhVDuowz:0fba728f5964ea54160a5b18317d92df</string></value> </member> <member> <name>expire_time</name> <value><int>1073116091</int></value> </member> <member> <name>server_time</name> <value><int>1073116031</int></value> </member> </struct></value> </param> </params> </methodResponse>
