Pulp_rpm advanced copy workflow using http

Support
#1

Problem:
I am trying to perform the workflow described here using http to talk to the API:

The examples in the docs are high level HTTP commands, and I can’t figure out how to get http to send an option value formatted as a JSON. This is what I have tried:

(pulp) [vagrant@pulp3-source-fedora35 ~]$ echo $CONFIG_STRING
[{"source_repo_version": "/pulp/api/v3/repositories/rpm/rpm/18519322-b653-4eb6-abd6-d4280b051246/versions/1/", "dest_repo": "/pulp/api/v3/repositories/rpm/rpm/e73a0382-9b09-4bfe-bb6d-8e9822580d45/"}]
(pulp) [vagrant@pulp3-source-fedora35 ~]$ http post ${BASE_ADDR}/pulp/api/v3/rpm/copy/ config="$CONFIG_STRING"
HTTP/1.1 400 Bad Request

{
    "non_field_errors": [
        "Provided copy criteria is invalid:'['\\'[{\"source_repo_version\": \"/pulp/api/v3/repositories/rpm/rpm/18519322-b653-4eb6-abd6-d4280b051246/versions/1/\", \"dest_repo\": \"/pulp/api/v3/repositories/rpm/rpm/e73a0382-9b09-4bfe-bb6d-8e9822580d45/\"}]\\' is not of type \\'array\\'']'"
    ]
}

I am sure this is just some trivial http syntax problem, but I don’t know how to solve it. Any help is appreciated.

Try with a colon config:=, see RPM examples here.

You can also read JSON from a file and specify config:=@my.json in parameters, I personally find it the easiest.

Here is also a quite small but helpful cheatsheet for httpie: httpie cheatsheet.
