MoinMoin 1.5.8 上传附件的XMLRPC API实现

一、服务端

1. 修改/usr/lib/python2.5/site-packages/MoinMoin/wikirpc.py，在class XmlRpcBase中增加如下函数：

    def xmlrpc_putAttachment(self, pagename, attachname, data):
        """ Set attachname associated with pagename to data

        @param pagename: pagename (utf-8)
        @param attachname: attachment name (utf-8)
        @param data: file data (base64)
        @rtype boolean
        @return True if attachment was set
        """
        pagename = self._instr(pagename)
        # User may read page?
        if not self.request.query_string.startswith('action=xmlrpc'):
            if not self.request.user.may.read(pagename):
              return self.notAllowedFault()

            if not self.request.cfg.xmlrpc_putpage_enabled:
              return xmlrpclib.Boolean(0)
            if self.request.cfg.xmlrpc_putpage_trusted_only and not self.request.user.trusted:
              return xmlrpclib.Fault(1, "You are not allowed to edit this page")
            # also check ACLs
            if not self.request.user.may.write(pagename):
              return xmlrpclib.Fault(1, "You are not allowed to edit this page")

        attachname = wikiutil.taintfilename(attachname)
        filename = AttachFile.getFilename(self.request, pagename, attachname)
        if os.path.exists(filename) and not os.path.isfile(filename):
          return self.noSuchPageFault()
        open(filename, 'wb+').write(base64.decodestring(data))
        os.chmod(filename, 0666 & config.umask)
        AttachFile._addLogEntry(self.request, 'ATTNEW', pagename, os.path.basename(filename))
        return xmlrpclib.Boolean(1)

另外别忘记import相关库：

import os, base64

2. 修改/usr/lib/python2.5/site-packages/MoinMoin/PageEditor.py，对class PageEditor的saveText函数做如下修改：
找到如下行：

if not self.request.user.may.save(self, newtext, rev, **kw):
            msg = _('You are not allowed to edit this page!')
            raise self.AccessDenied, msg

修改为：

if not self.request.user.may.save(self, newtext, rev, **kw) and not self.request.query_string.startswith('action=xmlrpc'):
            msg = _('You are not allowed to edit this page!')
            raise self.AccessDenied, msg

这么做的主要原因是，有时候xmlrpc客户端无法认证，导致执行失败，所以内部用的话，干脆就取消xmlrpc的认证了…

3. 重启MoinMoin

二、客户端代码举例

import xmlrpclib
import base64

#import  MoinMoin.auth as authmodule
#from MoinMoin.support.BasicAuthTransport import BasicAuthTransport
#username = 'will'
#password = 'mima'
#authtran = BasicAuthTransport(username, password)

wiki = xmlrpclib.ServerProxy("http://192.168.0.100/mywiki/?action=xmlrpc2")

file = open('ar01.png', 'r').read()
print wiki.putAttachment("pageName", "at01.png", base64.encodestring(file))

print wiki.WhoAmI()
