How do I specify a value nested in an array in a Mockoon rule?

Question

I'm trying to mock different responses in mockoon based on value1 in the following body request:

{
"foo":"bar",
"records" : [{
  "key1" : "value1",
  "key2" : "value2"
  }
]
}

The logical approach would have been to point as records[0].key1 to compare the value, but that does not seem to work.

Answer 1

A little reading goes a long way.

The answer for my case is as follows:

records.0.key1

This is from the Adding response rules from the Mockoon documentation, https://mockoon.com/docs/latest/route-responses/dynamic-rules/:

body: keep empty to match against the full raw body content. use a path to access one of its properties. The syntax is based on the object-path library like users.0.name. This is compatible with request's bodies of Content-Type application/json, application/x-www-form-urlencoded, multipart/form-data, application/xml, application/soap+xml or text/xml. Properties containing dots are supported by escaping the dots: key.key.with.dot. Please note that XML bodies are parsed using xml-js package. Refer to this page or the package documentation for more information on how the XML is parsed and how to fetch specific properties. Please also note that multipart/form-data only supports fields. Uploaded files will be ignored.

Aside from the dot notation records.0.key1, Mockoon also supports JSONPath. So, you should be able to fetch an array element by using the following syntax:

$.records[0]
