Starting azure data factory with incoming parameter which is a json

Question

I want to start my data factory with parameters. For that I defined a parameter "param" in my factory. The parameter is of type string and contains a json object like this

{
  "url": "http://mySpecialFile.csv",
  "name": "testing"
  "destination: "farAway"
}

Now how can I a access these values in my factory. Is it necessary to define for each attribue a variable? And can I extract for example the value of url? I tried it like this

(@json(@pipeline().parameters.param).url)

But this does not work, it will write this value into the variable? Is there better way to access the incoming json object? Also if I define for each json entry a variable I need to change my factory if the json changes?

Thanks for any advice

Answer 1

In Azure Data factory pipeline parameter for Json object type of data there is Data type called Object.

Here I created Pipeline parameter named json with Object data type and your sample value.

from this parameter to access particular value you can use dynamic parameter like @pipeline().parameters.json['value_which_you_want']

e.g. @pipeline().parameters.json['url'],@pipeline().parameters.json['name'],@pipeline().parameters.json['destination']

And it is fetching proper data.
