对于像https://watson-speech.mybluemix.net/microphone-streaming.html这样的简单语音转文本应用程序，是否有一些libcurl脚本？

Question

I made a lite plan on IBM and wanted to transcribe speech from a microphone into a container and create an audio file on my server. (as on the example page here For this, I use the libcurl of PHP.

How do I use the API key and the other variables I got via JSON-snippet?

"apikey": "<api-key>",
"iam_apikey_description": "<description>",
"iam_apikey_name": "<apikey-name>",
"iam_role_crn": "<role-crn>",
"iam_serviceid_crn": "<serviceid_crn>",
"url": "https://gateway-lon.watsonplatform.net/speech-to-text/api"

I tried this:

$json      = file_get_contents('./srv/lb/watson/watson.json');
$json_data = json_decode($json,true);

$file      = fopen('./srv/data/0001.flac', 'r');
$size      = filesize('./srv/data/0001.flac');
$filedata  = fread($file,$size);
$headers   = array(
"Content-Type: audio/flac",
"Transfer-Encoding: chunked"
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $json_data['url']);
curl_setopt($ch, CURLOPT_USERPWD, "apikey:".$json_data['apikey']);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $filedata);
curl_setopt($ch, CURLOPT_INFILE, $file);
curl_setopt($ch, CURLOPT_INFILESIZE, $size);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$executed = curl_exec($ch);
curl_close($ch);
var_dump($executed);

But I got:

string(153) "{ "code": 404, "code_description": "Not Found", "error": "No route found for http://gateway-lon.watsonplatform.net/speech-to-text/api (usher)" }"
