Viewing the Output of Azure Functions (AF)
Let's view the output of Azure Functions (AF).
We'll cover the following...
Viewing output
Let’s try to invoke “Hello” and confirm that it works. We can use the serverless invoke command for that.
serverless invoke \--function hello \--data '{"name": "Viktor"}'
The output is as follows.
Serverless: Initializing provider configuration...Serverless: Logging into AzureServerless: Using subscription ID: 7f9f9b08-7d00-43c9-9d30-f10bb79e9a61Serverless: Invocation url: http://20200628211206-eus-dev-azure-function.azurewebsites.net/api/hello?name=ViktorServerless: Invoking function hello with GET requestServerless: "Hello Viktor"
The last line is the output we’re looking for. We got the “Hello Viktor” message confirming that the response is indeed coming from the newly deployed function. However, while that confirmed our function is accessible through the serverless CLI, we need to verify that it’s available to everyone through an API or a browser. So we need the address that we got when we deployed the function.
We can retrieve almost any information related to the functions in a project by outputting the info.
serverless info
The output is as follows.

As we can see, that’s the same info we got at the end of the deploy process, just in a different format. It’s a strange combination of something at the top (it looks like YAML, but it’s not), and JSON at the bottom.
What matters, for now, is the name of the function that we can use to guess what the URL of the function is. It’s available at the top next to Function App Name, as well as at the bottom under the block with the ...
