Hi guys,
i have a rest call that returns json how would i go about using that data in my web Parser..

Json data from REST call data is as below
{
"value": "NORMAL"
}

Url="http://SomePlace/rest/status/server"
RegExp="(?siU)"value": "(.*)".*"

i would like to know if this is possible or am i smoking my socks.

Could some pne please point me in the right direction.

Thanks in advance.

Pretty much exactly like that...

Code: Select all

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

[MeasureServer]
Measure=Plugin
Plugin=WebParser
Url=http://SomePlace/rest/status/server
RegExp=(?siU)"value": "(.*)"

[MeasureRest1]
Measure=Plugin
Plugin=WebParser
Url=[MeasureServer]
StringIndex=1

[MeterRest1]
Meter=String
MeasureName=MeasureRest1
FontSize=12
FontColor=255,255,255,255
SolidColor=47,47,47,255
Padding=5,5,5,5
AntiAlias=1

Hi jsmorley,
Thanks for the quick response.

i have tried your example and i am getting the following error

NOTE (18:54:21.114) WebParserGuide\WebParserGuide.ini: Refreshing skin
DBUG (18:54:21.114) WebParserGuide\WebParserGuide.ini: Reading file: C:\Users\wlucas\Documents\Rainmeter\Skins\WebParserGuide\WebParserGuide.ini

ERRO (18:54:21.114) WebParserGuide\WebParserGuide.ini - [MeasureServer]: WebParser: RegExp matching error (-1)

Are there setting on rain meter that could cause it to fail on my side. i am using your code exactly other than the correct url.

do you know of any public restful services that return json that you could use in an example, like a twitter feed. could it be that my server is returning the json weird. i looks like it finds the resource, the regular expression is what fails and that is my Achilles heel.

the code is fine.
the problem is your initial post. you did not post the actual JSON response. you posted something you probably copied and pasted from a manual and is formatted to make it easier to read.

Hi moshi
i kind of figured it was that. i am using postman the chrome add on. i see you are right that which i pasted earlier was the pretty view of the json.
this is the Raw view, from postman

{"value":"NORMAL"}

i have modified the RegEx it now looks like this,

Url=http://10.0.1.124:7080/rest/status/server
RegExp=(?siU)"value":"(.*)"

even with the modified script i am getting "WebParser: RegExp matching error (-1)"

i managed to resolve the issue.

turns out jsmorley code worked

i had an authentication problem, i found this by running fiddler. As soon as the widget updated i got a 401 error. My jboss server would return authentication failure html page. how i found this was by making my regEx "(?siU)<html>(.)</html>". Making what the widget pulled visible.

i then put the username and password in the URL as my server does support basic authentication.

thanks jsmorley and moshi

you guys pointed me in the right direction
