Question

我正在按照本教程在IBM Bluemix中设置语音到文本服务： https://www.ibm.com/watson/developercloud/doc/speech-to-text/tutorial.shtml

我已经安装并测试了先决条件，但是当我尝试输入时出现错误：

curl -X POST -u <username>:<password>
--header "Content-Type: audio/flac"
--header "Transfer-Encoding: chunked"
--data-binary @<path>audio-file.flac
"https://stream.watsonplatform.net/speech-to-text/api/v1/recognize?continuous=true"

我收到了以下错误：

curl: no URL specified!
curl: try 'curl --help' or 'curl --manual' for more information

我在直接访问网址时测试了用户名和密码，但它确实有效。我为音频文件输入的路径也是正确的，因为我刚刚复制了它。

有谁知道如何解决这个问题？提前致谢！：）

Answer 1

您缺少新线路的转义。尝试这样的事情：

curl -X POST -u "myusername":"mypassword" \
--header "Content-Type: audio/flac" \
--data-binary "@audio-file1.flac" \
--data-binary "@audio-file2.flac" \
"https://stream.watsonplatform.net/speech-to-text/api/v1/recognize?timestamps=true&word_alternatives_threshold=0.9&keywords=%22colorado%22%2C%22tornado%22%2C%22tornadoes%22&keywords_threshold=0.5&continuous=true"

好的，当我进入路径时，我忘记了双引号。但现在它返回此HTML代码：
