PHP Azure OCR - 在數組中轉換JSON

Question

我正在使用Azure OCR服務，現在我想要將數據保存到數組中。 不幸的是我總是收到此錯誤信息：

PHP Warning: json_decode() expects parameter 1 to be string, object given in XXX on line 43 

我的輸出IST：

{"language":"en","textAngle":-2.5000000000000346,"orientation":"Up","regions":[{"boundingBox":"896,2104,1528,688","lines":[{"boundingBox":"896,2104,1528,688","words":[{"boundingBox":"896,2104,1528,688","text":"DFG"}]}]}]} 

我的代碼是：

$request->setHeader($headers); 
    $parameters = array(
     // Request parameters 
     'language' => 'unk', 
     'detectOrientation ' => 'true', 
    ); 

    $url->setQueryVariables($parameters); 
    $request->setMethod(HTTP_Request2::METHOD_POST); 
    $body = array('url' => 'https://i.imgur.com/2sUbQC8.jpg'); 
    $request->setBody(json_encode($body)); 

    // Request body 


    try 
    { 
     $response = $request->send(); 
     echo $response->getBody(); 
     $json = json_decode($response, true); 

    } 
    catch (HttpException $ex) 
    { 
     echo "Fehler :("; 
     echo $ex; 
    } 

?>

你不應該叫echo $response->getBody(); 相反，它分配到一個變量：

$json = $response->getBody();

然後你就可以把它變成一個數組：

$array = json_decode($json, true);
