Question

I am sending a SOAP POST and I am getting a “HTTPError: HTTP Error 415: Unsupported Media Type” @ response = urllib2.urlopen(req)

data = """<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:Header>
    <AutotaskIntegrations xmlns="http://autotask.net/ATWS/v1_5/">
      <PartnerID>1</PartnerID>
    </AutotaskIntegrations>
  </soap:Header>
  <soap:Body>
    <getThresholdAndUsageInfo xmlns="http://autotask.net/ATWS/v1_5/">
    </getThresholdAndUsageInfo>
  </soap:Body>
</soap:Envelope>"""

headers = {
    'Content-Type': 'application/soap+xml; charset=utf-8'
    'Host: "webservices.autotask.net"'
    'Content-Type: text/xml; charset=utf-8'
    'Content-Length: len(data)'
    'SOAPAction: "http://autotask.net/ATWS/v1_5/getThresholdAndUsageInfo"'
    }

site = 'https://webservices.autotask.net/atservices/1.5/atws.asmx'
auth_handler = urllib2.HTTPBasicAuthHandler()
auth_handler.add_password(realm='webservices.autotask.net',
                          uri=site,
                          user='[e-mail]',
                          passwd='mypw')
opener = urllib2.build_opener(auth_handler)
urllib2.install_opener(opener)
page = urllib2.urlopen(site)                            #errors out 415 here
req = urllib2.Request(site, data, headers)
response = urllib2.urlopen(req)

What am I doing wrong? Thanks!

Answer 1

The Content-Length value in the headers dictionary seems wrong

'Content-Length: len(data)' 

and also some other values.

I would fix it with:

headers = {
    'Content-Type': 'application/soap+xml; charset=utf-8',
    'Host': 'webservices.autotask.net',
    'Content-Length': len(data),
    'SOAPAction': 'http://autotask.net/ATWS/v1_5/getThresholdAndUsageInfo'
}
