This document is very preliminary, but describes a working
|
|
system.
|
|
|
|
1 System level requests
|
|
|
|
1.1 Login and authentication
|
|
|
|
Authentication for user logins is handled internally no differently
|
|
than for the typical phpGroupWare login via web browser.
|
|
Server logins, added for XML-RPC and SOAP, are only slightly
|
|
different. For either protocol, user and server login and
|
|
authentication and subsequent requests are handled by their
|
|
respective server apps, xmlrpc.php and soap.php. A server
|
|
is identified by a custom HTTP header, without which a normal
|
|
user login will be undertaken.
|
|
|
|
A client or server sends the appropriate XML-RPC or SOAP
|
|
packet containing host, user, and password information to
|
|
the phpgw server. The server then assigns a sessionid and
|
|
key, which is returned to the client in the appropriate
|
|
format.
|
|
|
|
Our current method for authenticating requests after successful
|
|
login is via the Authorization: Basic HTTP header to be
|
|
sent by the client or requesting server. The format of this
|
|
header is a base64 encoding of the assigned sessionid and
|
|
kp3 variables, seperated by a ':'.
|
|
|
|
Further security may be obtained by using SSL on the client
|
|
and server. In the future, we may encrypt/descrypt the data
|
|
on either end, or at least provide this as an option. The
|
|
sessionid and key variables will make this possible, and
|
|
relatively secure.
|
|
|
|
1.1.1 system.login
|
|
|
|
The first request a client will make is the system.login
|
|
method. Here is a sample of a server login packet in XML-RPC:
|
|
|
|
<?xml version="1.0"?>
|
|
|
|
<methodCall>
|
|
|
|
<methodName>system.login</methodName>
|
|
|
|
<params>
|
|
|
|
<param>
|
|
|
|
<value><struct>
|
|
|
|
<member><name>server_name</name>
|
|
|
|
<value><string>my.host.name</string></value>
|
|
|
|
</member>
|
|
|
|
<member><name>username</name>
|
|
|
|
<value><string>bubba</string></value>
|
|
|
|
</member>
|
|
|
|
<member><name>password</name>
|
|
|
|
<value><string>gump</string></value>
|
|
|
|
</member> </struct></value>
|
|
|
|
</param>
|
|
|
|
</params>
|
|
|
|
</methodCall>
|
|
|
|
And the same in SOAP:
|
|
|
|
<?xml version="1.0"?>
|
|
|
|
<SOAP-ENV:Envelope
|
|
|
|
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
|
|
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" xmlns:xsd="http://www.w3.org/1999/XMLSchema"
|
|
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
|
|
xmlns:si="http://soapinterop.org/xsd"
|
|
|
|
xmlns:ns6="http://soapinterop.org" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
|
|
|
|
<SOAP-ENV:Body> <ns6:system_login>
|
|
|
|
<server_name xsi:type=":string">my.host.name</server_name>
|
|
|
|
<username xsi:type=":string">bubba</username>
|
|
|
|
<password xsi:type=":string">gump</password>
|
|
|
|
</ns6:system_login>
|
|
|
|
</SOAP-ENV:Body>
|
|
|
|
</SOAP-ENV:Envelope>
|
|
|
|
The same style of packet would be required for a user/client
|
|
login. A successful login should yield the following reply:
|
|
|
|
<methodResponse>
|
|
|
|
<params>
|
|
|
|
<param>
|
|
|
|
<value><struct>
|
|
|
|
<member><name>sessionid</name>
|
|

<value><string>cf5c5534307562fc57915608377db007</string></value>
|
|
|
|
</member>
|
|
|
|
<member><name>kp3</name>
|
|
|
|
<value><string>2fe54daa11c8d52116788aa3f93cb70e</string></value>

</struct></value>
|
|
|
|
</param>
|
|
|
|
</params>
|
|
|
|
</methodResponse>
|
|
|
|
And a failed login:
|
|
|
|
<methodResponse>
|
|
|
|
<params>
|
|
|
|
<param>
|
|
|

2 Business layer requests
|
|
|
|
Once a successful login return packet has been received and
|
|
sessionid/kp3 have been extracted, every subsequent packet
|
|
sent to the phpgroupware server must be preceded by an Authorization
|
|
header. Here is a sample header:
|
|
|
|
POST /phpgroupware/xmlrpc.php HTTP/1.0
|
|
|
|
User-Agent: PHP XMLRPC 1.0
|
|
|
|
Host: my.local.host
|
|
|
|
Authorization: Basic ZDgxNDIyZDRkYjg5NDEyNGNiMzZlMDhhZTdlYzAxZmY6NTU3YzkyYjBmNGE4ZDVlOTUzMzI2YmU2OTQyNjM3YjQ=
|
|
|
|
Content-Type: text/xml
|
|
|
|
Content-Length: 875
|
|
|
|
The longish string is a base64 encoding of the $sessionid
|
|
. ':' . $kp3. For now this is our only supported authentication
|
|
method. Additional methods would probably also affect the
|
|
methodCalls. This is certainly open to discussion. Following
|
|
is a typical request for some contact data:
|
|
|
|

|

|

3 More to come...
|
|
|
|
Documenting every single call will be difficult, but should
|
|
be done. In leiu of this, please see the class.bo{APPNAME}.inc.php
|
|
files in each application/inc directory in the phpgroupware
|
|
cvs. In this file will be a list_methods() function, which
|
|
returns the information to the server about input/output
|
|
structure for each call. If the file does not have this
|
|
function, then it is not yet workable via this interface.
|
|
As for the actual functions, they are also in this file.
|
|
Generally, they will all accept associative array input
|
|
and return same, but not always. This code is in flux, have
|
|
fun.
