Re: Geo::WebService::Elevation::USGS
This one gives:
Unable to get page at httpfetch.pl line 35.
I wonder if all of these are redirects:
# Does not work
my $test = get('https://nationalmap.gov/epqs/') or die 'Unable to get
page'; # Does not work
#my $test = get('https://nationalmap.gov/epqs/pqs.php') or die 'Unable
to get page'; # Does not work
#my $test = get('http://www.wrh.noaa.gov/zoa/mwmap3.php?map=usa') or die
'Unable to get page'; # Does not work
#my $test = get('http://www.glorecords.blm.gov/') or die 'Unable to get
page'; # Does not work
#my $test = get('https://glorecords.blm.gov/default.aspx') or die
'Unable to get page'; # Does not work

Good, do we know two things:
- your LWP::Simple is correctly installed
- you have no proxy
Next step is to see what is the result of https://nationalmap.gov/epqs/
So you should try with (note the / at the end):
my $test = get('https://nationalmap.gov/epqs/') or die...
Problem is that it is going through redirections and beacuase it is
encrypted, it is almost impossible to debug by hand.

This is really the first question, the first step to build the
diagnostic.
So far, I cannot even decide whether the version of LWP::Simple
installed on your machine is properly working or not. So I cannot decide
whether it is a network problem or a software problem.

Re: Geo::WebService::Elevation::USGS
I was thinking it might give the fill in form that you get when you go here: https://nationalmap.gov/epqs/ I think you are right. It is acting as intended when visited with a browser.

Re: Geo::WebService::Elevation::USGS
In my Firefox it is set at:
"Use system proxy settings"
I turned it off briefly, but didn't really see
any changes.
I do not implement a proxy in LWP::Simple.
I don't think I use a system Proxy:

Invalid Coordinates".
This URL runs the PHP script pqs.php, this script needs input
coordinates, if there is no coordinates supplied, this script returns
the message about invalid coordinates.
This message is not a message from your browser, it is not a message
from the web server, it is a message from pqs.php. Your browser and the
web server are just fine.
And frankly speaking, what result are you expecting? pqs.php is a script
that returns some data depending on the input data you give. You give no
input, you get no output.
https://nationalmap.gov/epqs/
will. I imagine this may have something
to do with redirects, but who knows.
This URL is missing the filename part (after the last /), in that case,
the web server uses a default file (depending on the configuration of
the web server) and the default file is presenting a page that asks for
coordinates.
So you are asking 2 differents URL, that corresponds to two different
pages, each page giving the correct result.
When I put
https://nationalmap.gov/epqs/pqs.php
into a web browser it says:
General failure: Invalid Coordinates
When I put
http://ned.usgs.gov/epqs/pqs.php
into a web browser it says the same exact thing.
And it is expected that the URL with http and with https give the same
correct result.
When I go to
https://nationalmap.gov/epqs/
and put -90.76983 for X
and put 38.72360 for Y
and hit "Get Elevation"
it gives:
3DEP 1/3 arc-second
583.54
Feet
When I go to:
https://nationalmap.gov/epqs/pqs.php?x=-90.76983=38.72360=feet=xml
it gives:
3DEP 1/3 arc-second
583.54
Feet
So that works.
It works because you are providing correct input.
Best regards,
Olivier

Re: Geo::WebService::Elevation::USGS
The url ending pgs.php requires the query_string data to be looked up. The
url ending in “/“ is for the interactive page for a browser, say. You
shouldn’t have to specify “:443” (from your 500 error) instead just use
“https://“ prefix. In general http connections forward themselves to https;
if I go to nationalmap.gov I get forwarded to
https://www.usgs.gov/core-science-systems/national-geospatial-program/national-map
I don’t think env vars will help.

Re: Geo::WebService::Elevation::USGS
Thank you. That helps me a lot to know that it works for you.
Your code, exactly as you sent it, still does not work for me.
It gives:
500 Can't connect to nationalmap.gov:443 (Bad address) at trash.pl line 19.
I'm going to try to assign an environment variable to my
system. I doubt that will fix it, but I am trying just
about everything.
I still can't figure out why it works on some URL's,
and not others. It's probably going to take me a
long time to figure this out.

Thanks for the response. Yeah, I don't understand why https://nationalmap.gov/epqs/pqs.php won't open in a browser, but https://nationalmap.gov/epqs/ will.

Re: Geo::WebService::Elevation::USGS
Thank you all for the responses.
I now think this has nothing to do with
Geo::WebService::Elevation::USGS. See
the script below for other web links that
LWP::Simple cannot reach and parse. I have
not figured out why, but the problem is not
with USGS.pm,.
#!/usr/bin/perl
use strict;
use warnings;
use LWP::Simple;
chdir 'C:/Copy';
# Works
#my $test = get('http://osgeo-org.1560.x6.nabble.com/') or die 'Unable
to get page'; # Works

print "\nAll done.\n\n\$test = $test\n\n";
__END__
There is stuff posted about this problem. I have
been through using UserAgent, declaring the browser,
environment variables, and other things and it
still doesn't work. Good thing I don't need this
or it would be driving me crazy. I will probably
move on to other things now.

$ua->env_proxy;

Re: Geo::WebService::Elevation::USGS
Telnet doesn’t use the colon $ telnet But i think you’re right about the addresses being wrong bad. “http” means port “:80” and “https” uses port “:443” On Mon, Aug 26, 2019 at 10:27 PM Uri Guttman wrote: > On 8/26/19 8:00 PM, Mike wrote: > > > > > > > > use constant USGS_URL => 'https://ned.usgs.gov/epqs/pqs.php'; > > to > > use constant USGS_URL => 'https://nationalmap.gov/epqs/pqs.php'; > > > > have you tried to just telnet to those hosts? > > telnet nationalmap.gov:443 > telnet: could not resolve nationalmap.gov:443/telnet: Name or service > not known > telnet ned.usgs.gov:443 > telnet: could not resolve ned.usgs.gov:443/telnet: Name or service not > known > > > so there is something wrong with the urls and not the code (or the code > has bad urls). > > and just getting the web pages is also failing > > GET https://ned.usgs.gov/epqs/pqs.php > General failure: Invalid Coordinates > > GET https://nationalmap.gov/epqs/pqs.php > General failure: Invalid Coordinates > > i dunno the module but it seems that you may not be passing in any > coordinates or something else is needed. > > uri > > -- > To unsubscribe, e-mail: beginners-unsubscr...@perl.org > For additional commands, e-mail: beginners-h...@perl.org > http://learn.perl.org/ > > > -- Andy Bach afb...@gmail.com Not at my desk
