IBM-Watson文字语音转换引发“ 403：禁止”错误

Question

我正在尝试使用IBM watson api进行文本到语音服务。如果我使用curl命令，则该服务有效，但是当我尝试使用Python SDK使用srrvice时，它使我陷入错误之下。

追踪（最近通话）：发送中的文件“ /anaconda3/lib/python3.6/site-packages/ibm_cloud_sdk_core/base_service.py”，第234行response.status_code，error_message，http_response = response）ibm_cloud_sdk_core.api_exception.ApiException：错误：禁止，代码：403方法失败，状态码为403：[禁止

下面是curl命令

curl -X GET -u "apikey:myapiKey" --output hello_world.wav "https://api.eu-de.text-to-speech.watson.cloud.ibm.com/text-to-speech/api/v1/synthesize?accept=audio/wav&text=Hallo%20Welt&voice=de-DE_DieterVoice"

下面是python代码

from ibm_watson import TextToSpeechV1
from ibm_cloud_sdk_core.authenticators import IAMAuthenticator


from ibm_watson import ApiException
import json

IBM_API_ENDPOINT = "https://api.eu-de.text-to-speech.watson.cloud.ibm.com/text-to-speech/api/v1/synthesize"


IBM_TTS_API_KEY = "myAPIKey"

authenticator = IAMAuthenticator(IBM_TTS_API_KEY)
text_to_speech = TextToSpeechV1(authenticator=authenticator)
text_to_speech.set_service_url(IBM_API_ENDPOINT)


try:
    with open('IBM.wav', 'wb') as audio_file:
        audio_file.write(text_to_speech.synthesize("Hallo world", voice='de-DE_DieterVoice', accept='audio/wav').get_result().content)

except ApiException as ex:
    print("Method failed with status code " + str(ex.code) + ": " + ex.message)

Answer 1

这是因为您要在端点末尾添加方法和版本。当您使用用于IBM-Watson的Python SDK时，SDK在调用synthesize时应注意应用该方法。因此，您的终结点应该仅是：

IBM_API_ENDPOINT = "https://api.eu-de.text-to-speech.watson.cloud.ibm.com"
