Allow passing an SSL context to the httpx client

[ap--]

Hello everyone 👋

Because the SyncFunctionsClient verify argument is cast to bool, it's not possible to pass down an SSL Context to the underlying httpx.Client.
This can be problematic when working with custom certificates in corporate environments.

SyncFunctionsClient

functions-py/supabase_functions/_sync/functions_client.py

Line 36 in 2675964

verify=bool(verify),

httpx.Client

https://github.com/encode/httpx/blob/26d48e0634e6ee9cdc0533996db289ce4b430177/httpx/_client.py#L646

# the verify arg of `httpx.Client` accepts ssl.SSLContext
verify: ssl.SSLContext | str | bool = True,

proposed fix

A trivial fix would be to remove the bool() cast. I'll open a PR for discussion.

Cheers,
Andreas

We're working on a better option of allowing you to pass your own httpx client so that you can access all the params directly and customize your httpx client to it's fullest without any limitations. #201

Hi @ap-- in the latest version you can pass a custom httpx instance when initializing the client, use that for providing the SSL context.

Thanks.

This can now be done in version 2.16.0 of supabase-py using your own custom httpx client.

import certifi
import ssl
from httpx import Client
from supabase import create_client, ClientOptions

# This SSL context is equivelent to the default `verify=True`.
ctx = ssl.create_default_context(cafile=certifi.where())

with Client(verify=ctx) as http_client:
    # Create a client with the custom httpx client
    options = ClientOptions(httpx_client=http_client)

    client = create_client(supabase_url, supabase_key, options=options)

or if you use this library directly you can do:

import certifi
import ssl
from httpx import Client
from supabase_functions import SyncFunctionsClient

# This SSL context is equivelent to the default `verify=True`.
ctx = ssl.create_default_context(cafile=certifi.where())

with Client(verify=ctx) as http_client:
    # Create a client with the custom httpx client
    client = SyncFunctionsClient(
        url="https://example.com",
        headers={"Authorization": "Bearer token"},
        http_client=http_client,
    )
