Why WebParser Download Stops Working?

[balala]

I think in any case the browser-check is passed, but there is then a re-direct to the actual image. WebParser just can't deal with a re-direct like that, where the Powershell function seems to be able to.

Ok, thanks.

I think the key to that may be the C#-based System.Net.WebClient, which is likely a slightly more robust animal than the C++ WinINet API calls used in WebParser.

No comment for my part. Have no idea...

Skin just a bit shorter, and a test in the Powershell to avoid an unwanted log message.

GetMoon.ini

Code: Select all

[Rainmeter]
Update=1000
DynamicWindowSize=1
AccurateText=1

[Variables]
URL=https://static.die.net/moon/800.jpg

[MeasureGetMoon]
Measure=Plugin
Plugin=RunCommand
OutputType=ANSI
Program=PowerShell.exe
Parameter=-NoProfile -ExecutionPolicy Bypass -Command "& '.\GetMoon.ps1' '#URL#' '.\Moon.jpg'"
UpdateDivider=600
OnUpdateAction=[!CommandMeasure #CURRENTSECTION# "Run"]
FinishAction=[!SetOption MeterShowMoon ImageName "Moon.jpg"][!UpdateMeter MeterShowMoon][!Redraw]

[MeterContainer]
Meter=Shape
Shape=Ellipse 100,100,96 | StrokeWidth 0

[MeterShowMoon]
Meter=Image
Path=#CURRENTPATH#
W=200
PreserveAspectRatio=1
Container=MeterContainer

GetMoon.ps1:

Code: Select all

$url = $args[0]
$file = $args[1]

if (Test-Path $file) 
{
  Remove-Item $file
}

$wc = New-Object System.Net.WebClient
$wc.DownloadFile($url, $file)

No need for the separate Calc measure to execute the RunCommand. That measure can execute itself based on UpdateDivider.

I implemented this method and it worked like a charm!

Thank you very much.
Issue solved!

Great!

There was one thing missing:
Since OnDownloadErrorAction does not work in Measure MeasureGetMoon, how to detect Download error in Measure MeasureGetMoon?

I tried my old trick

Code: Select all

IfMatchMode=1
IfMatch=.*\w+
IfNotMatchAction=[!Log "Not Match"]
IfMatchAction=[!Log "Match"]

and it did not work.

IfMatch = .+

Thanks khanhas, but IfMatch=.+ did not work for me (for example, when the URL is wrong) with the above MeasureGetMoon.
There seem to be more problems than regular expression.

Since OnDownloadErrorAction does not work in Measure MeasureGetMoon, how to detect Download error in Measure MeasureGetMoon?

Try the followings: first remove the above set of IfMatch options from the [MeasureGetMoon] measure, then add the following String measure to your code:

Code: Select all

[MeasureGetMoonResult]
Measure=String
String=[MeasureGetMoon]
IfMatch=^$
IfNotMatchAction=[!Log "Error"]
IfMatchAction=[!Log "No error"]
DynamicVariables=1
UpdateDivider=-1
Disabled=1

Finally add the following two bangs to the FinishAction option of the [MeasureGetMoon] measure: [!EnableMeasure "MeasureGetMoonResult"][!UpdateMeasure "MeasureGetMoonResult"] (with these bangs, the complete FinishAction option becomes: FinishAction=[!EnableMeasure "MeasureGetMoonResult"][!UpdateMeasure "MeasureGetMoonResult"][!SetOption MeterShowMoon ImageName "Moon.jpg"][!UpdateMeter MeterShowMoon][!Redraw]).
