如何使用curl访问IBM语音到文本api? [英] How can I access IBM speech-to-text api with curl?

问题描述

我无法使用curl访问IBM Bluemix上的语音文本API！我从文档中尝试了该示例，以获取带有curl的无会话请求，但该示例无效.我收到无效的userID/密码消息.

I cannot access the speech-to-text API on IBM Bluemix with curl! I tried the example from the documentation for a sessionless request with curl and it didn't work; I got an invalid userID/password message.

这是我遇到的错误:

" {代码":401，错误":未授权"，说明": "2016-10-08T15:22:37-04:00，发生错误ERCDPLTFRM-DNLKUPERR时， 进入 https://158.85.132.94:443/speech-to-text/api/v1/recognize?timestamps=true&word_alternatives_threshold=0.9&continuous=true ， 无效的用户名和/或密码.请确认您的凭据 与您要访问的端点匹配.一个常见的错误正在尝试 针对GA使用实验性或Beta版的凭据 释放，反之亦然"}"

"{ "code" : 401 , "error" : "Not Authorized" , "description" : "2016-10-08T15:22:37-04:00, Error ERCDPLTFRM-DNLKUPERR occurred when accessing https://158.85.132.94:443/speech-to-text/api/v1/recognize?timestamps=true&word_alternatives_threshold=0.9&continuous=true, Invalid UserId and/or Password. Please confirm that your credentials match the end-point you are trying to access. A common error is trying to use credentials from an experimental or beta release against a GA release or vice versa" } "

任何人都可以向我展示一个如何通过curl获得对语音到文本api的无会话请求的api的可行示例吗?

Can anyone show me a working example of how to get an api sessionless request to speech-to-text api with curl?

推荐答案

无会话调用的文档可用

The documentation for sessionless calls is available here.

确保您创建了Watson Speech-to-Text服务的实例，并使用了该服务中的凭证(而不是Bluemix用户ID和密码).

Make sure you create an instance of the Watson Speech-to-Text services and use the credentials from that service (not your Bluemix user id and password).

您可以在Bluemix UI中创建服务并获取凭证，也可以通过命令行创建它:

You can create the service in the Bluemix UI and get the credentials, or you can create it via command line:

$ cf create-service speech_to_text standard my_service

然后您可以创建服务凭证并获取它:

And then you can create service credentials and get it:

$ cf create-service-key my_service credentials-1

$ cf service-key my_service credentials-1
Getting key credentials-1 for service instance my_service as [e-mail]...

{
 "password": "FJXUG6????",
 "url": "https://stream.watsonplatform.net/speech-to-text/api",
 "username": "147e438e-f633-4e40-8351-aaaaaaaaaa"
}

然后，您可以在curl脚本中使用上面的用户名和密码.请参阅下面的curl命令和结果(为安全起见，我屏蔽了用户名，密码和其他字段):

You can then use the username and password from above in your curl script. See curl command and results below (I masked username, password and other fields for security):
