How to use activity output with period in fieldname JSON in Azure Data Factory

Question

I am currently setting up a pipeline, where I need to extract a value from a JSON response (Web activity output). This output has a period in the fieldname. How do I use this value?

The simplified output is as follows:

{
"aud": "https://login.----.com/auth/authentication/resources",
"abc.organisationUserCode": "----",
"abc.clusterUrl": "https://url-to-use.com",
}

If I use @activity('GetclusterUrl').output.abc.clusterUrl I get the following error:

The expression 'activity('GetclusterUrl').output.abc.clusterUrl' cannot be evaluated because property 'abc' doesn't exist

Is there a way to for example use an escape character to be able to use this value further down the pipeline?

请试试这个表达：

@activity('GetclusterUrl').output['abc.organisationUserCode']
