Hi Vera,
To allow CORS in Tomcat add the following to the bottom of the web.xml file in
the $TOMCAT_HOME/conf directory
<filter>
<filter-name>CorsFilter</filter-name>
<filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
<init-param>
<param-name>cors.allowed.origins</param-name>
<param-value>*</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CorsFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Hope this helps.
Graham

Subject: Re: [Geoserver-users] Authenticate WFS-T
I managed to get the authentication to work as well. Perhaps you could share
how you did it for future reference.
From leaflet I used ajax as per one of the links I provided:
//this option uses the leaflet.wms.js plugin:
https://github.com/heigeo/leaflet.wms
var options_l = {'transparent': true,'tiled': true,'format':
'image/png'};
var source_l =
L.WMS.source("https://your_server:8080/geoserver/wms?";, options_l);
var myLayer = source_l.getLayer(' myLayer ');// Get the layer
// myLayer .addTo(map); //Optionally add the layer to the map
layerControl.addOverlay( myLayer, " My Layer "); //Optionally
add the layer to the layer control - object must exist.
// Assuming myLayer **WITHOUT** user:pass in the url
// The result is that when the request is first made a login window is
initiated allowing the user to authenticate into GeoServer.
/*
$.ajax({
url: myLayer.url,
data: myLayer.params,
method: 'GET',
error: function(jqXHR, textStatus, errorThrown){
// Handle not authorised here
alert("Could not authorise!");
},
success: function(){
alert("Authorised!");
// Yuppieeeeee!
//map.addLayer(myLayer); // The browser will set up
the
// authentication in the
request for you
}
}); */
I am not certain exactly how this functions because after the initial login the
credentials seam to be saved somewhere even when the page is reloaded and even
when the browser is re-started. I would like to understand where the
credentials are stored.
Now I am trying to enable CORES on tomcat as the next issue is a "No
'Access-Control-Allow-Origin' header is present on the requested resource."
error.

hello
I finally managed to authenticate myself
now it's the content of the query that does not pass :
org.geoserver.wfs.WFSException: Error performing insert: Error inserting

Yet I try to replicate the examples
Le 15/04/2019 à 00:05, Vera Green a écrit :
I have the same problem with leaflet and WMS. Same setup with data in
postgreSQL, basic authentication and the Catalog Mode set to Challenge which I
have read is required.
This related post suggest the authentication should be "handled automatically"
but this does not occur:
https://gis.stackexchange.com/questions/227553/geoserver-rest-authentication-form
<https://gis.stackexchange.com/questions/227553/geoserver-rest-authentication-form>
this post suggests using the fetch API although personally I was not able to
implement this:
https://gis.stackexchange.com/questions/284954/how-to-authenticate-wfs-requests-being-made-to-geoserver-through-openlayers-appl/285069
This post is also related:
https://stackoverflow.com/questions/51758817/how-to-authorize-accessing-the-geoserver-layers
And then there is also this post:
https://gis.stackexchange.com/questions/86790/authentication-in-geoserver-2-4-x-from-a-web-application/97448#97448
Despite of this I am still unable to establish the link between GeoServer and
Leaflet receiving the 401 error. Note that if I am already logged into
GeoSever then the WMS layer works fine, therefore I am confident that
establishing JavaScript or ajax based method to authenticate the user into
GeoServer at the beginning of the session is the solution. However I am still
unsure about how to do this.

Hello
I have a layer cite: administration that is linked to a POSTGRESQL database and
I can not configure a wfs-t authentication. My query in openlayers always gives
error 401 and in geoserver log 'Failed login'
The request is

and in openlayers I try:
var headers = new Headers ({
'Authorization': 'Basic' + btoa (username + ':' + password),
'Content-Type': 'application / x-www-form-urlencoded'
})
fetch ( 'http: // ip_adress: 8080 / geoserver / wfs', {
method: 'POST',
headers: headers,
body: request
}). then (function (response) {
return response.text ();
}). then (function (text) {
var result = text;
console.log ( 'result -------------------------------------------- ------ ',
result)
});
I set up a user group
I tried to put a data access rule for this layer - cite.administration.w - but
it does not memorize. Even with reading the geoserver manual 2.15 I can not do
it.
Can you help me please ?
