I'm trying to use the xml.metadata.insert service on an installation of Geonetwork 3.1. I've had success putting the parameters (a snippet in the case of data) directly in the URL in a web-browser, such as the correct response is returned (uuid and id of the created resource) and a metadata record is created.

However, trying to emulate the same thing in either python (through the "requests" package) or in postman, results in a strange behaviour of a 200 status code, but html being returned (below) instead and the resource not being created.

<!DOCTYPE html
  SYSTEM "html">
<html ng-app="gn_login" lang="eng" id="ng-app">
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

    </head>
    <body data-ng-controller="GnCatController">
        <div class="navbar navbar-default gn-top-bar" data-ng-hide="layout.hideTopToolBar" data-ng-include="'../../catalog/templates/top-toolbar.html'"></div>
        <div data-ng-include="'../../catalog/templates/signin.html'"></div>
        <div ng-include="'../../catalog/templates/info.html'"></div>
        <script>var geonet = {provide:function(s){},require:function(s){}};</script>
        <script src="/geonetwork/static/lib.js"></script>
        <script src="/geonetwork/static/gn_login.js"></script>
        <noscript>
            <div class="alert" data-ng-hide="">
                <strong></strong>
            </div>
        </noscript>
    </body>
</html>

Is there anything that I'm doing incorrectly to receive this response?

It's been a few years since I was working with GeoNetwork, but I think you may need to handle authentication. With the requests library you can use a Session to store your credentials. Here's a function I used as part of a larger script.

def create_geonetwork_session(self):
    BASE_URL = "https://yourgeonetworksite.com/geonetwork/srv/eng/"
    LOGIN = BASE_URL + "j_spring_security_check"
    self.gn_session = requests.Session()
    self.gn_session.auth = (self.USER, self.PASSWORD)
    login_r = self.gn_session.post(LOGIN)

The most important thing is using requests.Session() and supplying your credentials in a tuple to session.auth. Once you have a session created, use that for performing your insert (ie. instead of requests.post, use session.post) and the login should get passed along.

Hope this helps!
