Parse URL in Azure functions

Question

Am learning how to use Azure functions and so new to it. I have a httptrigger Azure function written in NodeJs. I am thinking of a logic on how to parse data from httptrigger function URL and use it in my code. Would like some suggestions on this?

In simple words,

I would like to know how to pass a string parameter to the functions URL.
Then parse the string from the URL and use it in my code logic.

Can you add an example of that data? Did you checked Azure docs for that? — Daniel Netzer, Feb 08 '18 at 17:34

See an example in Customize the HTTP endpoint.

You can define route in function.json:

"route": "products/{category:alpha}/{id:int?}"

and then get URL parts from context:

var category = context.bindingData.category;
var id = context.bindingData.id;

Mikhail's answer works if you want to put the "parameters" in the base part of the URL separated by /. However, if you wanted to use query parameter syntax (e.g. http://myEndpoint?myParam1=10&myParam2=hello), those show up already parsed in context.req.query
