From ff62581a874915df21b1423a145c84ca00419ef3 Mon Sep 17 00:00:00 2001 From: unknown Date: Wed, 20 May 2026 12:40:32 +0700 Subject: [PATCH] fix: resolve 500 error on generate-proxy (malformed cookie, session reuse, retry) Breaking changes: None. Fully backward-compatible. Bugfixes: - Malformed Cookie header fixed: '; sb-api-auth-token' -> 'sb-api-auth-token' (leading semicolon broke Udio's cookie parser, causing 500 Server Error) - Added requests.Session with connection reuse (was creating new TCP socket per request, triggering anti-bot heuristics) - Exponential backoff retry for 500/502/503/504 (was: fail immediately) - Error output now shows Udio's response body (was: just status code) - Updated User-Agent from Chrome 123 -> 125 New features: - Optional cloudscraper support (pip install cloudscraper, use_cloudscraper=True) - Configurable timeout, max_retries, proxies - Python logging instead of print() Refs: #7 --- example.py | 44 +++++++ requirements.txt | 3 +- setup.py | 14 ++- udio_wrapper/__init__.py | 245 +++++++++++++++++++++------------------ 4 files changed, 190 insertions(+), 116 deletions(-) create mode 100644 example.py diff --git a/example.py b/example.py new file mode 100644 index 0000000..f5a9bb2 --- /dev/null +++ b/example.py @@ -0,0 +1,44 @@ +#!/usr/bin/env python3 +""" +Example: Using the improved UdioWrapper (v0.0.4). +Fixes the 500 error from Issue #7. +""" + +import logging +import sys + +from udio_wrapper import UdioWrapper + +logging.basicConfig( + level=logging.INFO, + format="%(asctime)s [%(levelname)s] %(message)s", + datefmt="%H:%M:%S", +) + +AUTH_TOKEN = "YOUR_SB-API-AUTH-TOKEN" # Get from Udio cookies + +# Fix #1: use_cloudscraper=True bypasses Cloudflare if Udio added it +# Fix #2: retries on 500/502/503/504 with exponential backoff +# Fix #3: fixed malformed Cookie header (was "; sb-api-auth-token" → "sb-api-auth-token") +# Fix #4: proper error logging that shows Udio's response body +wrapper = UdioWrapper( + auth_token=AUTH_TOKEN, + timeout=90, + max_retries=3, + use_cloudscraper=False, # set True if you install cloudscraper +) + +# Quick health check — verify the session works +print("Generating song...") +result = wrapper.create_song( + prompt="A relaxing jazz melody with piano", + seed=-1, +) +if result: + print(f"Success!
