Azure 认知服务上的 PHP "Json Format Error"

Question

我正在尝试使用 Azure OCR 服务来获取图像的文本。 不幸的是，我总是收到此错误：

{"code"："BadArgument"，"requestId"："49cecd3b-7be3-4aaa-9a5e-fXXXXXXXXXXXXX"，"message"："JSON format error."}

我的代码是：

<?php
(http://hc.apache.org/httpcomponents-client-ga/)
require_once 'HTTP/Request2.php';
$request = new Http_Request2('https://westcentralus.api.cognitive.microsoft.com/vision/v1.0/ocr'); 
$url = $request->getUrl();
$headers = array(
'Content-Type' => 'application/json',
'Ocp-Apim-Subscription-Key' => 'c7b9e7ab25b14XXXXXXXXXXXXXXXXXX',
);

$request->setHeader($headers);
$parameters = array(
'language' => 'unk',
'detectOrientation ' => 'true',
);
$url->setQueryVariables($parameters);
$request->setMethod(HTTP_Request2::METHOD_POST);

$request->setBody("https://image.spreadshirtmedia.net/image-server/v1/mp/compositions/P116103877MPC131734766/views/1,width=300,height=300,appearanceId=1,backgroundColor=E8E8E8,version=1472099537/hallo-sprechblase-auf-babybauch-oder-babyshirt-t-shirts-maenner-premium-t-shirt.jpg");  
try
{
$response = $request->send();
echo $response->getBody();  
}
catch (HttpException $ex)
{
echo "Fehler :(";
echo $ex;
}
?>

您已将图像 URL 指定为正文，但需要按照错误消息指示将其编码为 JSON。 尝试：

$body = array('url' => 'https://image.spreadshirtmedia.net/image-server/v1/mp/compositions/P116103877MPC131734766/views/1,width=300,height=300,appearanceId=1,backgroundColor=E8E8E8,version=1472099537/hallo-sprechblase-auf-babybauch-oder-babyshirt-t-shirts-maenner-premium-t-shirt.jpg');
$request->setBody(json_encode($body));
