python: Unable to send a request to a service proxy

I’m trying to make a post request via the proxy API to a service without the k8s cluster without much luck. Found the below candidate API -

connect_post_namespaced_service_proxy
connect_post_namespaced_service_proxy_with_path
proxy_post_namespaced_service
proxy_post_namespaced_service_with_path

But was unable to attach a body (or extra headers to them):

Can anyone point to examples or documentation on how to do this?
What is the difference between the plain & _with_path APIs (the documentation for bot?

connect_post_namespaced_service_proxy:
       :param str path: Path is the part of URLs that include service endpoints, suffixes, and parameters to use for the current proxy request to service. For example, the whole request URL is http://localhost/api/v1/namespaces/kube-system/services/elasticsearch-logging/_search?q=user:kimchy. Path is _search?q=user:kimchy.

connect_post_namespaced_service_proxy_with_path:
       :param str path2: Path is the part of URLs that include service endpoints, suffixes, and parameters to use for the current proxy request to service. For example, the whole request URL is http://localhost/api/v1/namespaces/kube-system/services/elasticsearch-logging/_search?q=user:kimchy. Path is _search?q=user:kimchy.

What is the difference between the two sets of APIs?

connect_post_XXX
proxy_post_XXX

Thanks!

@jbyers19 as a workaround, you could use the ‘call_api’ method directly, sorta like:

path_params = {
        "name": "https:argocd-server:443",
        "namespace": "default",
        "path": "api/v1/session"
    }

body = {
        "username": "admin",
        "password": "password"
    }

response = v1.api_client.call_api(
            '/api/v1/namespaces/{namespace}/services/{name}/proxy/{path}', 'POST',
            path_params,
            [],
            {"Accept": "*/*"},
            body=body,
            post_params=[],
            files={},
            response_type='str',  
            auth_settings=["BearerToken"],
            async_req=False,
            _return_http_data_only=True, 
            _preload_content=True,
            _request_timeout=None,
            collection_formats={})

I’m using the async python client, but this should work with the sync one too I’d guess.

I believe those work the same. Kubernetes apiserver allows the request to specify the subpath that you want to connect to either through a query parameter or by directly composing the URL path. Those two APIs reflect the options that the openapi spec gives.

What is the difference between the two sets of APIs?

connect_post_XXX
proxy_post_XXX

the proxy_* methods are deprecated and removed, use connect_* instead

was unable to attach a body (or extra headers to them)

the upstream openapi spec needs to be fixed so that this client library can support writing body and additional headers. I will take a stab
