Call azure function from ADF

Question

Hi,

I have an azure function which takes three arguments i.e arg1, arg2, arg3 and does some processing. Gives error if the arguments are invalid or None. Here is how the code looks like:

def main(req: func.HttpRequest) -> func.HttpResponse:  
      
    arg1 = req.params.get('arg1')  
    arg2 = req.params.get('arg2')  
    arg3 = req.params.get('arg3')  
      
    if (not arg1) or (not arg3) or (not arg2):  
        return func.HttpResponse(  
             f"Please provide valid arguments. Args receive: arg1: \  
                 {arg1}, arg2: {arg2}, arg3 :{arg3} - Status:500",  
             status_code=500  
        )  
	  
	process(arg1,arg2,arg3)  

The azure function using activity is being called as follows:

but it gives an error as follows:

I have tried with Get method and providing arguments in headers. Can someone please help what could be the case? Could it be the way I am acessing these args in code the wrong way?

Answer 1

Hi,

It appears there was problem I was acessing the parameters inside azure function.

There are two ways with post method:

1. Send params via query and access them using req.params.get('arg1')
2. Send params via body and access them using req_body = req.get_json() arg1= req_body.get('arg1')

I have adopted 2nd approach now and it works fine.
