Re: CONNECTIONTYPE OGR is not working after upgrade to mapserver 7.2.2 from 6.4.1

Hi Jeff,

You really did it! I was searching for missing libs, version
mismatches and wrong path variables but it was as simple as using
the xml file the way you pointed out.

I can confirm that everything works as expected now. I'd like to
point out though (for the record) that the step of

ogrinfo wfs-request.xm

does not only test the file but also prepares it to be used. I
tested using the file without first using ogrinfo but that did not
succeed.

I still do not understand why this was not needed in Mapserver 6
but anyway the problem is solved.

Thanks so much for putting in all that effort and time to help so
very quickly. I think this list is one of the greatest strength
of Mapserver and I want to thank everybody who is helping here!

Best

Thanks
for providing the response, which indeed states "only WFS 1.0.0 or
0.0.14".

I just followed the GDAL WFS driver page now, and locally was able
to generate a map image with a VERSION=1.1.0 request, with the
following steps:

- (the following steps are adapted from the GDAL WFS driver page
https://gdal.org/drv_wfs.html )

- create a new file named "wfs-request.xml"

- paste the contents of:

<OGRWFSDataSource>

<URL> http://demo.mapserver.org/cgi-bin/wfs?SERVICE=WFS&amp;VERSION=1.1.0&amp;MAXFEATURES=1000 </URL>

</OGRWFSDataSource>

- (notice the escaped "&" as noted on the GDAL WFS driver
page)

- make a copy of that file (copy/paste "wfs-request.xml" ) in case
it is overwritten by this process

- test this file/connection through the commandline:

ogrinfo wfs-request.xml

- you should see a response listing the available layers:

INFO: Open of `wfs-request.xml'

using driver `WFS' successful.

1: continents

2: cities

- now we know the name to use in our MapServer layer "DATA"
parameter, so in this case we will use "continents"

- edit your .map file and point your layer to that wfs-request.xml
in the CONNECTION, and set the correct DATA parameter from the
ogrinfo response above, such as:

LAYER

NAME "continents-test"

TYPE POLYGON

STATUS ON

CONNECTION "wfs-request.xml"

CONNECTIONTYPE OGR

DATA "continents"

PROJECTION

"init=epsg:4326"

END

CLASS

NAME "My Continents"

STYLE

COLOR 255 128 128

OUTLINECOLOR 96 96 96

END

END

END # Layer

- (use my small mapfile for testing: https://pastebin.com/GYrXyc9A
)

- now finally have MapServer generate a map image from that WFS
version 1.1.0 connection, by testing at the commandline:

shp2img -m wfs-110-client.map -o ttt.png -all_debug 5

- a file named 'ttt.png' should be generated of the map image, and
at the commandline the response should end with something like:

msSaveImage(ttt.png) total time: 0.015s

msFreeMap(): freeing map at 00228B70.

freeLayer(): freeing layer at 001F1828.

shp2img total time: 3.013s

*** tested with MS4W 4.0.0 (MapServer 7.4.0-dev, GDAL 2.4.0)

Hope that helps,

-jeff
