[propose] Named access to HTTP response

[ccidral]

Request

Ability to refer to HTTP response data by name.

Implementation

A fellow named Huachao Mao wrote an amazing HTTP client for VSCode from which we can get some inspiration: https://github.com/Huachao/vscode-restclient

His HTTP client allows binding a variable name to an HTTP request, so that the HTTP response becomes accessible via that name. It uses the syntax @name variable_name in a comment in the scope of the HTTP request.

Example:

###
# @name bananas
GET http://localhost/greeting

###
POST http://localhost/something/{{bananas.response.body.foo}}

{
  "message": "{{bananas.response.body.greeting}}"
}

The example above assumes that:

1. GET http://localhost/greeting returns { "foo": 123, "greeting": "hello" }
2. The content type is application/json so that the response is automatically parsed as JSON

The rest is self-explanatory.

Once the response is received, it binds the response object to the bananas variable name.

Thanks for request! For now you can solve this task using response handlers scripts. But maybe there is should be more easier and obvious way. I created issue: https://youtrack.jetbrains.com/issue/IDEA-240301
