httplib HTTPConnection request problem

[scummer]

Hi,

I am having a problem with the httplib HTTPConnection object. While I
can easily send requests that don't have any payload (ie. "get"), I
encounter issues if I want to post xml data. If you look at the class
below, when req == 'getFreeBusyInf o' all functions perfectly, but when
req == 'conflictReques t' I run into problems of the nature "400 Bad
Request". As you will notice, I also tried the shorter HTTPConnection
instance method "request", feeding it a dictionary of the header
arguments and the xml payload, but that didn't fly either. With the
headers in this format, I get the error:

AttributeError: 'str' object has no attribute 'iteritems' in line 737
of httplib.py

However, this dictionary format is exactly the same as what I found in
an example in the python documentation.

Class description and example of the xml payload are as follows:

class Connector:
def __init__(self, server):
self.server = 'http://'+server
#self.h1 = httplib.HTTPCon nection('my.pro xy.org', 3128)
self.h1 = httplib.HTTPCon nection('xxx.xx x.xxx.xxx', 80)

def sendInfo(self, req, confDict, xml=None):
print xml
if req == 'getFreeBusyInf o':
self.h1.putrequ est('GET',
self.server+"/servlet/webdav.freebusy ?username="+con fDict['users']+"&server=netli ne.de&start="+s tr(confDict['request_start'])+"&end="+str(c onfDict['request_end']))
self.h1.puthead er('Accept-Language', 'de, en-us;q=0.2')
self.h1.puthead er('Translate', 'f')
self.h1.puthead er('User-Agent', 'SLOX HolidayInfo')
self.h1.puthead er('Host', self.server)
self.h1.endhead ers()
elif req == 'conflictReques t':
self.h1.putrequ est("POST",
self.server+"/servlet/webdav.calendar/conflict.xml")
self.h1.puthead er("Accept-Language", "de, en-us;q=0.2")
self.h1.puthead er("Translate" , "f")
self.h1.puthead er("User-Agent", "SLOX HolidayInfo")
self.h1.puthead er("Host", confDict['server'])
self.h1.puthead er("Content-Length", str(len(xml)))
self.h1.puthead er("Authorizati on", "Basic
"+str(confD ict['base64Auth']))
self.h1.endhead ers()
self.h1.send(xm l)
#headers = {"Accept-Language": "de, en-us;q=0.2", "Translate" : "f",
"User-Agent": "SLOX HolidayInfo", "Host": confDict['server'],
"Content-Length": str(len(xml)), "Authorization" : "Basic
"+str(confD ict['base64Auth'])}
#self.h1.reques t('POST',
self.server+"/servlet/webdav.calendar/conflict.xml", headers, xml)

def receiveInfo(sel f):
rec = self.h1.getresp onse()
return rec

def closeConnection (self):
print 'Closing connection....'
self.h1.close()


The XML data looks something like this:

<?xml version="1.0" encoding="UTF-8"?><D:multista tus
xmlns:D="DAV:"> <D:propertyupda te
xmlns:D="DAV">< D:set><D:prop>< S:begins
xmlns:S="SLOX:" >108180720000 0</S:begins><S:end s
xmlns:S="SLOX:" >108197994000 0</S:ends><S:clien tid
xmlns:S="SLOX:" >HolidyInfoID </S:clientid><S:f olderid
xmlns:S="SLOX:" ></S:folderid><S:t itle xmlns:S="SLOX:" >HolidayInfo
Conflict Request</S:title><S:appo intment_request
xmlns:S="SLOX:" >yes</S:appointment_r equest><S:membe rs
xmlns:S="SLOX:" ><S:member>xyzx yz</S:member></S:members></D:prop></D:set></D:propertyupdat e></D:multistatus>

Incidentally, I set this same thing up using sockets and everything
worked perfectly. However, I need to now use with a proxy so that is
why I moved to the httplib module. I also tried the urllib2 module
but the only request data to be sent is
application/x-www-form-urlencoded and I need to send xml.

If someone can help me out here, I would certainly appreciate it.

Thanks,

Scum

Re: httplib HTTPConnection request problem

First make sure that you urlencode the xml like the docs do:

params = urllib.urlencod e({'xml': xml})

Make sure the key is something the server is expecting. Then make sure you call request properly:

self.h1.request ('POST', self.server+"/servlet/webdav.calendar/conflict.xml",
params, headers)

Notice that params comes before headers.

Not tested but that looks like what your problem might be...

dunno what's wrong with your code, but i recently used HTTPConnection
to transfer an XML payload to an apache + webware setup. the code below
actually works:

# --- BEGIN ---

from httplib import HTTPConnection

atomMIME = 'application/x.atom+xml'
conn = HTTPConnection( 'locahost', 80)

print '--------------------------------'
print 'Create a new entry'
print '--------------------------------'

headers = {'Content-Type': atomMIME}
postData = '''
<?xml version="1.0" encoding="iso-8859-1"?>
<entry xmlns="http://purl.org/atom/ns#">
<title>A post</title>
<created>2003-08-12T23:53:03Z</created>
<summary>An automated post</summary>
<content type="text/html" mode="escaped"> This is a test</content>
</entry>
'''.strip()

conn.request('P OST','/reflex/atom/AtomHandler', postData, headers)
res = conn.getrespons e()
assert res.status == 201 # created?

print res.status, res.reason

entryURI = res.msg['location']
print "location:" , entryURI

print '*** PASSED ***'

conn.close()

# --- END ---



hope this helps.
