How do I chain requests using variables

[lispercat]

I looked in the examples of both IntelliJ and rest.nvim but couldn't find examples of using output saved in variable from a previous request like:

# @name postgress_res
GET https://dev.service-now.com/api/now/table/u_attestation_config?sysparm_query=u_asset_name%3DPostgres
Authorization: Basic xxx

# @name postgress_tech_owner
GET {{postgress_res.response.body.result[0].u_technology_owner.link}}
Authorization: Basic xxx

When I execute this request there are syntax errors in the log. What could be the problem?

There are 2 types of http syntax for REST plugins. One from intellij and one from famous vscode plugin.

Both tree-sitter-http and rest.nvim itself only support intellij-style syntax, where you should put request delimiter (###) between requests to separate them. Unless, every text under header section will be parsed as raw request body.

More detail about syntax

By intellij spec, These lines can *close* the request body.

• response redirect prefix (>> or >>!)
• response handler script prefix (> {%)

Also, tree-sitter-http parser will skip # @name=value syntax while parsing raw response body (this won't close the request body though). This is only custom syntax rule I added on top of intellij-style http syntax.

By following intellij-style http syntax, rest.nvim doesn't provide a way to extract request body inline.
You can add post-request script to do that instead:

# @name postgress_res
GET https://dev.service-now.com/api/now/table/u_attestation_config?sysparm_query=u_asset_name%3DPostgres
Authorization: Basic xxx

# @lang=lua
> {%
local body = vim.json.decode(response.body)
client.global.set("owner_link", body.result[1].u_technology_owner.link)
%}

###
# @name postgress_tech_owner
GET {{owner_link}}
Authorization: Basic xxx

Thanks so much, Seongmin! How can I debug scripts like this? Is there a way to print out a variable from it?

You can use familiar vim.* apis including vim.notify() or vim.print() inside lua post request script.
