Topic: AerisWeather forecast in Saratoga template [Resolved]

[Vasco]

Decided to try Aeris forecast to be ready for the demise of Dark Sky, but I'm not getting anything. Changed Settings.php to use Aeris, entered access ID and secret key, entered forecast area and units, but nothing. Aeris website records API hits but no json in .../cache.

Note that I do have to use a proxy for cURL, but that is/has been working fine for the DS forecast and all the other cURLs in the template.

Also, everything works OK for Aeris forecast in my PWS_Dashboard (not currently selected).

What have I forgotten?

So, a couple of issues.  Running a view source on wxforecast.php?force=1 shows

Code: [Select]

So first, the cache file isn't writable.. that likely needs a permissions fix.  I suspect the second issue is due to proxy headers being returned, but can't validate until the cache file is writable and visible from your website.

I'll check; but I get DS-forecast-json, meteoalarm, UV forecast and metarcache OK?

I suspect the second issue is due to proxy headers being returned, but can't validate until the cache file is writable and visible from your website.

Ahhh, we've seen that before. . .

EDIT: /cache has 775. . .

And, you'll need to replace

Code: [Select]

  $i = strpos($html,"\r\n\r\n");
  $headers = substr($html,0,$i-1);
  $content = substr($html,$i+4);
with

Code: [Select]

  $stuff = explode("\r\n\r\n",$html); // maybe we have more than one header due to proxy redirects
  $content = (string)array_pop($stuff); // last one is the content
  $headers = (string)array_pop($stuff); // next-to-last-one is the headers
for the two instances.  That's what we did with DS-forecast.php

That's what we did with DS-forecast.php

I've just found the PM of 11/8/22. . . sorry, Ken 

EDIT: That's it! Thanks, Ken.

No problem!  I'll remember to update the source with the next update to AW-forecast.php as needed.

[Vasco]

No problem!  I'll remember. . .

Wish I could say the same 

[Vasco]

Just been doing some updating, so I thought I would modify the new forecast scripts for my cURL proxy problems - just in case. Pleasantly surprised to find the $stuff mod already included in OWM-forecast.php  . . . but not in PW and VC. I presume I would need to do them too?


 

[saratogaWX]

Yes, sorry.. forgot to retrofit those into the basic DW-forecast script adapted for PirateWeather and VisualCrossing displays.  For some reason, the OWM request ALWAYS had an internal redirect to the actual data, so had to apply the $stuff mod to make it work.
