Dynamic values in paramater
Hi,
I am using the below paramters to pass in the URL to get the data from a web source which based on the start date and end date:
the below is from Advance Editor:
let
Source = Json.Document(Web.Contents("http://175.20.9.16:41000/PS/v1/ABC/Device/Meter?start_time=" & DeviceSD & "&end_time=" & DeviceED))
in
Source
I can successfully get the data for these paramaters (hard coded date), Now my requirement is to make these current values dynamic. The current value for the parameters "DeviceED" should be current datetime (like now()) and "DeviceSD" should be 3 days back datetime (like now()-3) rather than passing a hard coded datetime values.
Please suggest how to achieve this.
StartDate
EndDate
Hi jitpbi,
Perhaps you can try to split your url string and add optional parameters 'relative path' and 'query' to confirm if they works on power bi service side:
let url="http://175.20.9.16:41000/", Source = Web.Contents(url, [ RelativePath="PS/v1/ABC/Device/Meter", Query = [ start_time = DateTimeZone.ToText(DateTimeZone.From(Date.AddDays (DateTimeZone.UtcNow(),-3)),"yyyy-MM-ddThh:mm:ssZ"), end_time = DateTimeZone.ToText(DateTimeZone.UtcNow(),"yyyy-MM-ddThh:mm:ssZ") ] ]), Result=Json.Document(Source) in ResultUsing The RelativePath And Query Options With Web.Contents() In Power Query And Power BI M Code

I got the solution for this in my another post:

jitpbi , not very clear. try like DateTime.LocalNow
Hi jitpbi,
It seems like you want to get the current date with UTC format and using in the connector.If this is a case, you can consider using DateTimeZone functions to get the current date and format as specific UTC format you mention then concatenate with your raw URL strings.
let Source = Json.Document(Web.Contents("http://175.20.9.16:41000/PS/v1/ABC/Device/Meter?start_time=" & DateTimeZone.ToText(DateTimeZone.From(DeviceSD),"yyyy-mm-ddThh:mm:ssZ") & "&end_time=" & DateTimeZone.ToText(DateTimeZone.UtcNow(),"yyyy-mm-ddThh:mm:ssZ"))) in SourceRegards,

Hi Anonymous ,
I am getting the below error when tried this:
DataSource.Error: Web.Contents failed to get contents from 'http://175.20.9.16:41000/PS/v1/ABC/Device/Meter?start_time=2020-00-30T09:00:00Z&end_time=2020-08-02T08:08:22Z' (500): time data '2020-00-30 09:00:00' does not match format '%Y-%m-%d %H:%M:%S'
Thanks
Hi jitpbi,
My formula works will and these DateTime values are correctly formatted as the date timezone format as your methods.
According to your error message, I think this issue should more relate to your parameters. Please double-check and modify your query parameter 'start date', it seems like you are try to input an invalid start date with the month '0'.
