Access Denied Error with InvokeHTTP

ChuckE — Sat, 21 May 2022 01:04:47 GMT

I am using NiFi v.1.16.1

When I attempt to retrieve the weather data from the below URL, I don't get any response unless I specify "Always Output Response", and then I get an Access Denied response. However, these are free data feeds that work just fine using any other client,

e.g. curl https://w1.weather.gov/xml/current_obs/KSFO.xml

Anyone have any ideas what may be going on here?

Hi,

After some research I found in order to avoid getting the 403 error, you need to provide the User-Agent to the header as explained by the FAQ under the same domain (scroll below until you find 403 error):

https://weather-gov.github.io/api/general-faqs

To solve your problem you need to set the UserAgent Property on the invokeHttp processor. It can be something like: nifi/version 1.16.0

Hope that helps, if it does please accept solution.

Thanks

Yep! That is absolutely correct. Thanks for that. I spent more time trying to resolve this than I care to admit, because of my bias. Thanks for this @SAMSAL
