我使用了 azure 的 TTS（文本到语音）认知服务，使用的库是 python azure-cognitiveservices-speech == 1.17.0 我最初尝试并在 Heroku 云中部署了它，它按预期工作。
但是，当我在 VM 中部署它时，我收到了 CORS 错误。我的 CORS 设置正确，我尝试允许所有也没有帮助的主机（'*'）（我的后端是 Django）
speech_key = settings.SPEECH_KEY
service_region = settings.SERVICE_REGION
speech_config = speechsdk.SpeechConfig(subscription=speech_key, region=service_region)
speech_config.speech_synthesis_voice_name = "ar-SA-Naayf"
filename = './audio.wav'
filename = filename.replace('.wav', '_' + str(random.randint(10, 10000)) + '.wav')
audio_file_path = Path(str(filename)).resolve()
audio_config = AudioOutputConfig(filename=str(audio_file_path))
# Creates a speech synthesizer using the default speaker as audio output.
speech_synthesizer = speechsdk.SpeechSynthesizer(speech_config=speech_config, audio_config=audio_config)
# Receives a text from console input.
text = "Hello World"
result = speech_synthesizer.speak_text_async(text).get()
在我的 CORS 的 prod.py 中
ALLOWED_HOSTS = ['api.abc.com']
在我的 CORS settings.py 中
# Cors Header
# Allowed cors headers
CORS_ORIGIN_ALLOW_ALL = True
CORS_ALLOW_HEADERS = ('Authorization', 'Content-Type', 'Cache-Control', 'X-Requested-With')
错误：
Access to XMLHttpRequest at 'https://api.abc.com/tts/' from origin 'https://api-dev.abc.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
我应该研究哪些设置或更改配置？
