认知服务-错误创建FaceList和PersonGroup AZURE

Question

你能帮我吗我正在学习使用azure服务的认知服务，但我在使用文档中的forncecido模型时遇到了一些错误

<?php
// This sample uses the Apache HTTP client from HTTP Components (http://hc.apache.org/httpcomponents-client-ga/)
require_once 'HTTP/Request2.php';
// Replace <Subscription Key> with a valid subscription key.
$ocpApimSubscriptionKey = '98471c5c832e466688890f6c86f6c88d'; 

$request = new Http_Request2('https://brazilsouth.api.cognitive.microsoft.com/face/v1.0/facelists/{faceListId}');
$url = $request->getUrl();
$headers = array(
// Request headers
'Content-Type' => 'application/json',
'Ocp-Apim-Subscription-Key' => $ocpApimSubscriptionKey ,
);
$request->setHeader($headers);
$parameters = array(
// Request parameters
'faceListId' => 'sahara'
);
$url->setQueryVariables($parameters);
$request->setMethod(HTTP_Request2::METHOD_PUT);
// Request body
$request->setBody("{body}");
try
{
$response = $request->send();
echo $response->getBody();
}
catch (HttpException $ex)
{
echo $ex;
}
?>

我在php中运行这个脚本，它给了我以下错误

｛"error"：｛"code"："BadArgument"，"message"："请求正文无效。"｝｝

，你能告诉我我做错了什么吗

根据FaceList-Create API，主体格式为

{
"name": "sample_list",
"userData": "User-provided data attached to the face list."
}

我们需要用以下方式发送身体，然后它应该工作。

// Request body
$request->setBody('{"name":"facelistName","userData":"it is optional"}'); //replace it with your name and userData

如果要引用'HTTP/Request2.php';，我们需要安装http_request2

pear install http_request2

如何安装PEAR包管理器，请参阅此链接。

演示代码：

<?php
// This sample uses the Apache HTTP client from HTTP Components (http://hc.apache.org/httpcomponents-client-ga/)
require_once 'HTTP/Request2.php';
$request = new Http_Request2('https://xxx.api.cognitive.microsoft.com/face/v1.0/facelists/{faceListId}');
$url = $request->getUrl();
$headers = array(
// Request headers
'Content-Type' => 'application/json',
'Ocp-Apim-Subscription-Key' => 'xxxxxxxxxx', //replace it with your key
);
$request->setHeader($headers);
$parameters = array(
'faceListId' => 'facelistId'
);
$url->setQueryVariables($parameters);
$request->setMethod(HTTP_Request2::METHOD_PUT);
// Request body
$request->setBody('{"name":"facelistName","userData":"it is optional"}');//replace it with your name and userData
try
{
$response = $request->send();
echo $response->getBody();
}
catch (HttpException $ex)
{
echo $ex;
}
?>
