How to load WMS protected with username and password?

[aborruso]

Hi,
I'm able to access via GDAL in this way

gdalinfo --config GDAL_HTTP_AUTH BASIC --config GDAL_HTTP_USERPWD "$USERNAME_WMS":"$PASSWORD_WMS" "WMS:https://ogc-dev.sample.eu/geoserver/wms?"

I cannot find username and password as parameters in the add_wms_layer function. How can I load such a WMS layer into leafmap?

Thank you

Can you try it with ipyleaflet without leafmap? If it works with ipyleaflet, then we should be able to make it work with leafmap. Otherwise, it would be an upstream issue that should be reported to the ipylealfet repo.

Thank you @giswqs , I probably didn't understand you.

In that page the sample code is

from traitlets import Unicode


class TimeWMSLayer(WMSLayer):

    time = Unicode('').tag(sync=True, o=True)


time_wms = TimeWMSLayer(
    url='https://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r-t.cgi?',
    layers='nexrad-n0r-wmst',
    time='2005-08-29T13:00:00Z',
    format='image/png',
    transparent=True,
    attribution='Weather data © 2012 IEM Nexrad'
)

m2 = Map(basemap=basemaps.CartoDB.Positron, center=(30.661, -88.645), zoom=5)

m2.add(time_wms)

How to set username and password parameters?

From ChatGPT. Not sure if it works. If not, it is an ipyleaflet issue.

import ipyleaflet
from ipywidgets import HTML

# Define your WMS service URL and credentials
wms_url = "https://ogc-dev.sample.eu/geoserver/iride/wms?"
username = "your_username"
password = "your_password"

# Create a basic authentication header
auth_header = f"Basic {username}:{password}"

# Create the WMS layer
wms_layer = ipyleaflet.WMSLayer(
    url=wms_url,
    layers='your_layer_name',
    format='image/png',
    transparent=True,
    attribution='WMS Service',
    # Add the custom headers here
    headers={'Authorization': auth_header}
)

# Create a map
m = ipyleaflet.Map(center=(0, 0), zoom=2)

# Add the WMS layer to the map
m.add_layer(wms_layer)

# Display the map
m
