From 46fa5683517faabb291926f9397dcb5c109620b8 Mon Sep 17 00:00:00 2001 From: Justin Pecott Date: Tue, 14 Oct 2025 22:58:37 -0700 Subject: [PATCH 01/11] Add automatic browser-based OAuth flow with local HTTPS server MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements a seamless OAuth authentication experience: - Auto-opens browser to authorization URL - Spins up local HTTPS server to capture OAuth callback - Generates self-signed SSL certificate for localhost - Falls back to manual copy/paste flow if automatic fails - Shows success page in browser after authorization This eliminates the need for users to manually copy/paste URLs, making the initial setup much smoother. The implementation follows patterns used by popular CLI tools like gcloud, aws-cli, and gh. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- oauth_session.py | 141 +++++++++++++++++++++++++++++++++++++++++++---- 1 file changed, 130 insertions(+), 11 deletions(-) diff --git a/oauth_session.py b/oauth_session.py index 0ecec26..3a40dda 100644 --- a/oauth_session.py +++ b/oauth_session.py @@ -1,9 +1,46 @@ import json import pathlib +import webbrowser +import ssl +import threading +from http.server import HTTPServer, BaseHTTPRequestHandler from typing import Dict, List, Optional +from urllib.parse import urlparse, parse_qs from requests_oauthlib import OAuth2Session +class CallbackHandler(BaseHTTPRequestHandler): + """HTTP handler to capture OAuth callback.""" + + authorization_response = None + + def do_GET(self): + """Handle GET request with OAuth callback.""" + # Store the full URL + CallbackHandler.authorization_response = f"{self.path}" + + # Send success response + self.send_response(200) + self.send_header('Content-type', 'text/html') + self.end_headers() + + # Show success message + success_html = """ + + Authentication Successful + +

If no response after timeout, fall back to manual 4. If server didn't start, immediately fall back to manual Changes: - Fixed conditional logic to check server_ready first - Only open browser if server started successfully - Separate error messages for "server failed" vs "timeout" - Clearer flow control with nested if/else Now the automatic browser flow actually works! 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- oauth_session.py | 51 ++++++++++++++++++++++++------------------------ 1 file changed, 26 insertions(+), 25 deletions(-) diff --git a/oauth_session.py b/oauth_session.py index 3ac2ccd..71705b4 100644 --- a/oauth_session.py +++ b/oauth_session.py @@ -248,37 +248,38 @@ def _perform_oauth_flow(self) -> Dict: # Start local server to capture callback redirect_response, server_ready = self._start_callback_server(host, port, use_https) - # Wait for server to be ready before opening browser - if redirect_response is None or not server_ready.is_set(): + # Check if server started successfully + if not server_ready.is_set(): # Server failed to start, fall back to manual - print("\nAutomatic flow failed.") + print("\nAutomatic flow failed - server could not start.") print(f"Please visit: {authorization_url}") redirect_response = input("Paste the full redirect URL here: ") else: - # Server is ready, open browser + # Server started successfully, open browser webbrowser.open(authorization_url) - # If automatic flow timed out, fall back to manual - if redirect_response is None: - print("\nAutomatic flow failed or timed out.") - print(f"Please visit: {authorization_url}") - redirect_response = input("Paste the full redirect URL here: ") - else: - # Construct full redirect URL from path - # Parse the redirect URI to get base components - parsed_redirect = urlparse(self.config['redirect_uri']) - # Parse the callback path (includes query string) - parsed_callback = urlparse(redirect_response) - # Combine: use base from redirect_uri, path and query from callback - redirect_response = urlunparse(( - parsed_redirect.scheme, - parsed_redirect.netloc, - parsed_callback.path or parsed_redirect.path, - '', # params - parsed_callback.query, - '' # fragment - )) - print("✓ Authorization received!") + # Check if we got a response (redirect_response is set by _start_callback_server) + if redirect_response is None: + # Timeout waiting for callback + print("\nAutomatic flow timed out waiting for authorization.") + print(f"Please visit: {authorization_url}") + redirect_response = input("Paste the full redirect URL here: ") + else: + # Success!
