我一直在嘗試註冊一個回撥URL,以便與語音識別服務一起使用,但沒有成功。 我發送了以下POST請求,正文{}
和身份驗證。語音識別回撥註冊失敗
https://stream.watsonplatform.net/speech-to-text/api/v1/register_callback?callback_url=https://skaxsqsiq4.execute-api.us-east-1.amazonaws.com/test/watson/callback
我收到這樣的響應:
{
"code": 400,
"code_description": "Bad Request",
"error": "unable to verify callback url, challenge_string is missing or incorrect"
}
儘管打電話給我的端點自己回聲的挑戰串
curl -XGET https://skaxsqsiq4.execute-api.us-east-1.amazonaws.com/test/watson/callback?challenge_string=12345
返回:
12345
