Hi all,
I’m working on a Python API call to upload records from a fancy metadata submission form. I’m using the api/0.1/records post method, but I can’t seem to get it to work. It always gives me a 403 error, which if I understand the Swagger UI doc correctly, indicates I don’t have sufficient access. But this is a fresh GeoNetwork server, I’ve opened a session with the default admin username and password, and I can do an empty GET and receive a HTTP 200 response (and changing login details causes that to change to a 401 error).
I’ve tried adding auth details into the post command, but that didn’t change anything.
Any thoughts or ideas?
Code below
-- coding: utf-8 --
“”"
Accesses the GeoNetwork REST API to upload an xml metadata record.
Uses the Requests package for convenience

import requests
from xml.dom import minidom
def gn_api_xml_push(XMLFilePath):
GN_BaseURL = ‘http://[! YOUR GEONETWORK HERE]/geonetwork/’ #removed local IP address
GN_API_URL = GN_BaseURL + ‘api/0.1/records’
session = requests.Session()
session.auth=(‘admin’, ‘admin’) #Your username/password here
loginResponse = session.get(GN_API_URL)
OpenedFile = open(XMLFilePath, ‘r’)
XMLDoc = minidom.parse(OpenedFile) #turns a file object into an XML document
OpenedFile.close()
parameters = {
‘file’: [XMLDoc], #Unsure if this is the Array format needed, but the error is the same even if I pass an empty array in
‘rejectIfInvalid’: True
}
requestResponse = session.post(GN_API_URL, data=parameters)
if requestResponse.status_code == 201:
responseDict = requestResponse.json()
if responseDict[‘numberOfRecordsNotFound’] > 0:
return {‘response’: “not found”}
elif responseDict[‘numberOfNullRecords’] > 0:
return {‘response’: “empty”}
elif responseDict[‘numberofRecordsWithErrors’] > 0:
errorString = ‘’
for error in responseDict[‘errors’]:
errorString = errorString + error[‘message’] + ‘\n’
metadataErrorString = ‘’
for value in responseDict[‘metadataErrors’].values():
metadataErrorString = metadataErrorString + value[0][‘message’] + ‘\n’
return {‘response’:“Errors in metadata record”,
‘errors’: errorString,
‘metadataErrors’: metadataErrorString
}
elif responseDict[‘numberOfRecordsProcessed’] > 0:
return {‘response’: ‘processed’}
else:
return {‘response’: ‘Unknown response - HTTP 201 success’}
elif requestResponse.status_code == 403:
return {‘response’: ‘HTTP 403 - insufficient access’,
‘loginResponse’: loginResponse}
else:
return {‘response’: ‘Unknown’,
‘statuscode’: requestResponse.status_code,
‘loginResponse’: loginResponse}
PS: The Swagger UI “try it out” feature for this request also doesn’t seem to work… I just used a known working XML document but the response is 400 -
{
"message": "MultipartException",
"code": "unsatisfied_request_parameter",
"description": "The current request is not a multipart request"
}
Feels weird to me, but might just mean that the Swagger UI is out of date?
Thanks in advance,
Kim
